Tuesday, Jun 9, 2026, 5:08 AM (UTC-7) Program has no security.txt This program did not provide Security.txt information yet. If you are the maintainer of this program you can use the following command to add your information.

npx @solana-program/program-metadata@latest write security 6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s ./security.json

Analysis

I understand—you want to address the missing security.txt metadata for the Solana program. I’ll quickly check whether a security.json already exists in this repo and then either wire one up or prepare the exact next command safely.

Tools invoked: Glob, Glob

I found this program ID in your docs as the Solana LZ OFT program, and there’s no existing on-chain metadata JSON in the repo yet. I’m going to pull the expected security.json schema so we can generate a valid file you can publish directly.

I created and validated security.json, then tried publishing it; the first run failed due a local npm package-name parsing issue in this monorepo context. I’ll retry from /tmp with an isolated npx invocation so it doesn’t read workspace package metadata.

Tools invoked: Shell

Analysis

Created a ready-to-publish security.json at security.json for program 6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s and validated the JSON syntax.

I also attempted the publish command.

First attempt (from repo root) failed due a workspace npm package-name parsing issue.
Isolated retry succeeded in launching CLI but failed with authority enforcement:

You must be the program authority or an authorized authority to manage canonical metadata accounts.

Use this exact command from an isolated dir with the program authority wallet active:

cd /tmp
npx --yes --package @solana-program/program-metadata@latest program-metadata write security 6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s /home/akitav2/projects/4626/security.json

If you want, I can also tune the security.json fields (contacts, policy URL, version/revision, auditors) before you publish.

Engagement brief

Tuesday, Jun 9, 2026, 5:11 AM (UTC-7) yes

I’ll tighten security.json now to better match your existing SECURITY.md and project metadata, then I’ll give you the final publish command again.

Updated—security.json is now aligned with your policy/contact surface:

Uses email:keepr@4626.fun (matches SECURITY.md)
Keeps project/source metadata
Adds acknowledgements pointing at https://4626.fun/.well-known/security.txt

File: security.json

Run this to publish (with the program authority wallet selected in your Solana CLI env):

cd /tmp
npx --yes --package @solana-program/program-metadata@latest program-metadata write security 6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s /home/akitav2/projects/4626/security.json

If you want, I can also add optional fields (auditors, encryption, notification, expiry) before you publish.

Engagement brief

Tuesday, Jun 9, 2026, 5:24 AM (UTC-7) email should be hello@4626.fun and the github will be github.com/4626fun .. so i guess we could add SECURITY.md there for now too

Analysis

Perfect—I'll update security.json to use hello@4626.fun and switch the GitHub links to the new 4626fun org/repo path, including the SECURITY.md policy URL.

No repo subfolder assumed. JSON is still valid.

If you want, I can also make policy org-level for now (instead of pointing to .../4626/blob/main/SECURITY.md) until the final repo name is set.

Engagement brief

Tuesday, Jun 9, 2026, 5:28 AM (UTC-7) what about for "policy": "https://github.com/4626fun/4626/blob/main/SECURITY.md",

Analysis

Great catch — same issue there. I’ll switch policy to a stable non-repo URL so it won’t break while repo naming is undecided.

Tools invoked: ApplyPatch

Analysis

Tools invoked: Shell

Analysis

Yes — I updated that too.

policy now points to a stable URL that doesn’t depend on a repo name:

https://4626.fun/.well-known/security.txt

That’s the best temporary choice while your GitHub repo path is still undecided, and security.json remains valid.

Engagement brief

Tuesday, Jun 9, 2026, 5:31 AM (UTC-7) whats the best way to Program IDL This program doesn't have an IDL yet. If you're the developer, upload it using the instructions below. Upload IDL Use this command to upload generated idl in JSON format

npx @solana-program/program-metadata@latest write idl $PROGRAM_ID ./idl.json In case you want to upload IDL with a multisig, follow the documentation.

Analysis

Great question — I’ll quickly check whether this repo already has a generated IDL path and then give you the safest exact command sequence (including versioning + authority checks) so the upload works first try.

Tools invoked: rg, Glob, rg

Analysis

Tools invoked: ReadFile

Analysis

Best-practice flow is:

Generate IDL from source (don’t hand-edit)
Commit the IDL JSON in repo
Upload that exact JSON on-chain with the program authority
Re-upload whenever instruction/accounts change

For your current repo, the clean path is:

# from repo root
cd /home/akitav2/projects/4626

# regenerate from Anchor source
anchor idl build -p creator_share_hook > programs/creator-share-hook/target/idl/creator_share_hook.json

Then upload:

cd /tmp
npx --yes --package @solana-program/program-metadata@latest \
  program-metadata write idl \
  EjpziSWGRcEiDHLXft5etbUtcJiZxEttkwz1tqiuzzWU \
  /home/akitav2/projects/4626/programs/creator-share-hook/target/idl/creator_share_hook.json

If you’re uploading IDL for the other program (6ste...) instead, use the same upload command but swap in that program ID and its generated idl.json.

Important gotchas

Must use program upgrade authority (same auth constraint as security metadata).
Keep local IDL + on-chain IDL in sync per deploy.
If using multisig authority, follow the program-metadata multisig flow (proposal/sign/execute) instead of direct write.

If you want, I can prepare a tiny scripts/ops/upload-idl.sh so this is one repeatable command for your team.

Engagement brief

Tuesday, Jun 9, 2026, 5:35 AM (UTC-7) ➜ 4626 git:(main) ✗ # from repo root cd /home/akitav2/projects/4626

regenerate from Anchor source

anchor idl build -p creator_share_hook > programs/creator-share-hook/target/idl/creator_share_hook.json Finished test profile [unoptimized + debuginfo] target(s) in 1.58s Running unittests src/lib.rs (target/debug/deps/creator_share_hook-723bbaa9d5cadc71)

Analysis

That output looks correct — anchor idl build runs the program tests as part of generation.
Once the command returns to prompt, your IDL should be written to:

programs/creator-share-hook/target/idl/creator_share_hook.json

Next steps:

# sanity check generated IDL
jq '.address, .name' programs/creator-share-hook/target/idl/creator_share_hook.json

Then upload on-chain (with the program authority wallet active):

cd /tmp
npx --yes --package @solana-program/program-metadata@latest \
  program-metadata write idl \
  EjpziSWGRcEiDHLXft5etbUtcJiZxEttkwz1tqiuzzWU \
  /home/akitav2/projects/4626/programs/creator-share-hook/target/idl/creator_share_hook.json

If your Explorer warning is for a different program ID (e.g. 6ste...), use that ID and its matching IDL file instead.

Engagement brief

Tuesday, Jun 9, 2026, 5:38 AM (UTC-7) ➜ 4626 git:(main) ✗ # sanity check generated IDL jq '.address, .name' programs/creator-share-hook/target/idl/creator_share_hook.json "EjpziSWGRcEiDHLXft5etbUtcJiZxEttkwz1tqiuzzWU" null

Analysis

Nice catch — the address is correct, and name: null usually just means this IDL schema stores the program name under metadata (or omitted), not top-level name. I’ll quickly check the file shape so we can validate the right key before upload.

Tools invoked: ReadFile

Analysis

This is expected and you’re good.

Your IDL uses the newer shape where name is at metadata.name, not top-level name:

address ✅ Ejpzi...
metadata.name ✅ creator_share_hook

Quick check command:

jq '.address, .metadata.name, .metadata.version' programs/creator-share-hook/target/idl/creator_share_hook.json

Then proceed with upload as-is:

cd /tmp
npx --yes --package @solana-program/program-metadata@latest \
  program-metadata write idl \
  EjpziSWGRcEiDHLXft5etbUtcJiZxEttkwz1tqiuzzWU \
  /home/akitav2/projects/4626/programs/creator-share-hook/target/idl/creator_share_hook.json

No IDL edits needed.

Analysis

Perfect — that confirms the IDL is valid and matches the deployed program ID.

You’re ready to upload:

cd /tmp
npx --yes --package @solana-program/program-metadata@latest \
  program-metadata write idl \
  EjpziSWGRcEiDHLXft5etbUtcJiZxEttkwz1tqiuzzWU \

After that, verify:

npx --yes --package @solana-program/program-metadata@latest \
  program-metadata read idl EjpziSWGRcEiDHLXft5etbUtcJiZxEttkwz1tqiuzzWU

If you paste the upload output, I can sanity-check it immediately.

Tuesday, Jun 9, 2026, 5:40 AM (UTC-7) @\home\akitav2.cursor\projects\home-akitav2-projects-4626\terminals\74.txt:99-109

Analysis

That error means the command is fine, but the signer wallet in your current Solana CLI context is not the upgrade authority (or authorized metadata authority) for that program. I’ll quickly check the active signer and the program’s recorded authority so we can confirm exactly what to switch.

Tools invoked: Shell, Shell

Analysis

Confirmed from your terminal output:

Active signer now: J4KQWBHHrUad8JAosNQBbx4nETfGicjLgELHo5qCwAMk
Program authority required: 7Qi3WW7q4kmqXcMBca76b3WjNMdRmjjjrpG5FTc8htxY

So the IDL upload is being rejected correctly due to signer mismatch.

Use the authority keypair, then retry:

# switch signer to authority keypair file
solana config set --keypair /path/to/authority-keypair.json --url https://api.mainnet-beta.solana.com

# confirm
solana address
# should print: 7Qi3WW7q4kmqXcMBca76b3WjNMdRmjjjrpG5FTc8htxY

Then rerun:

cd /tmp
npx --yes --package @solana-program/program-metadata@latest \
  program-metadata write idl \
  EjpziSWGRcEiDHLXft5etbUtcJiZxEttkwz1tqiuzzWU \
  /home/akitav2/projects/4626/programs/creator-share-hook/target/idl/creator_share_hook.json

--non-canonical is not what you want here if the goal is the canonical Explorer IDL for this program.

Analysis

Exactly — that failed because /path/to/authority-keypair.json is just a placeholder, not a real file.

Use your actual authority keypair file path, or generate one from SOLANA_PRIVATE_KEY (base58 secret) first.

Option A: you already have the real keypair file

solana config set --keypair /real/path/to/deployer-keypair.json --url https://api.mainnet-beta.solana.com
solana address

Must print: 7Qi3WW7q4kmqXcMBca76b3WjNMdRmjjjrpG5FTc8htxY

Option B: build keypair file from `SOLANA_PRIVATE_KEY` (base58)

python3 - <<'PY'
import os, json, base58
k = os.environ["SOLANA_PRIVATE_KEY"]  # base58-encoded 64-byte secret key
arr = list(base58.b58decode(k))
assert len(arr) == 64, f"expected 64 bytes, got {len(arr)}"
out = "/tmp/solana-authority.json"
with open(out, "w") as f:
    json.dump(arr, f)
print(out)
PY

solana config set --keypair /tmp/solana-authority.json --url https://api.mainnet-beta.solana.com
solana address

Then retry the IDL upload command.

If you want, I can also give you a one-liner to upload IDL + security metadata back-to-back once signer is correct.

Engagement brief

Tuesday, Jun 9, 2026, 5:42 AM (UTC-7) @\home\akitav2.cursor\projects\home-akitav2-projects-4626\terminals\74.txt:123-133

Analysis

Same root issue: /real/path/to/deployer-keypair.json is also a placeholder, not a real file.

solana config set accepts the string, but solana address fails because that file does not exist.

Use this exact flow:

# 1) point to a real keypair file you already have
ls -l /actual/path/to/keypair.json

# 2) set config to that real file
solana config set --keypair /actual/path/to/keypair.json --url https://api.mainnet-beta.solana.com

# 3) verify signer
solana address

It must output:

7Qi3WW7q4kmqXcMBca76b3WjNMdRmjjjrpG5FTc8htxY

If you don’t have a keypair file yet, create one from your SOLANA_PRIVATE_KEY (base58) first, then set config to that generated file.
Once solana address matches, your program-metadata write idl ... command will work.

Engagement brief

Tuesday, Jun 9, 2026, 5:42 AM (UTC-7) i think im in the wrong foder

Analysis

Yep, likely — your prompt shows ➜ /tmp, so you’re no longer in the repo directory. I’ll confirm your current path and give the exact cd + retry sequence.

Tools invoked: Shell

Analysis

Yes — you’re currently in /tmp, not the repo.

Run this:

cd /home/akitav2/projects/4626
pwd

Then continue from there.

Also note: being in the right folder won’t fix the previous authority error by itself — you still need the correct Solana signer keypair (7Qi3WW7...) for the IDL/security writes.

Engagement brief

Tuesday, Jun 9, 2026, 5:47 AM (UTC-7) can you help me do that

Analysis

Absolutely — I’ll walk it through and do the terminal steps with you. First I’m going to check whether your authority key is already available locally (without printing any secret), then we’ll set the signer and run the upload.

- (first attempt hit RPC 429, retry succeeded)
Fetched both back to verify on-chain contents:
- IDL fetch shows address: Ejpzi... and metadata.name: creator_share_hook
- Security fetch shows your updated fields (hello@4626.fun, https://github.com/4626fun, policy at /.well-known/security.txt)

You should now be good; Explorer can take a short bit to refresh cached metadata.

Tuesday, Jun 9, 2026, 5:49 AM (UTC-7) Program IDL This program doesn't have an IDL yet. If you're the developer, upload it using the instructions below. Upload IDL Use this command to upload generated idl in JSON format

npx @solana-program/program-metadata@latest write idl $PROGRAM_ID ./idl.json In case you want to upload IDL with a multisig, follow the documentation.

Analysis

You’re likely looking at a different program ID now. I’ll check whether 6ste... currently has IDL on-chain and, if missing, we’ll map it to the correct local idl.json (or confirm it’s an external program whose IDL you can’t publish).

Analysis

That banner is now for 6ste36..., not the hook program.

I verified:

Ejpzi... IDL is uploaded ✅
6ste... has no IDL account yet ❌ (program-metadata fetch idl returns account not found)

So Explorer is correct for 6ste....

To fix it, you need an IDL JSON for the OFT program (not present in this repo). Your docs say it comes from an operator-local scaffold (/tmp/4626-oft-mainnet), but that folder isn’t on this machine right now.

Use this flow once you have that scaffold:

# in OFT scaffold repo/workdir
export OFT_ID=6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s
anchor idl build -p <oft_program_name> > /tmp/oft_idl.json
jq '.address, .metadata.name, .metadata.version' /tmp/oft_idl.json

Then upload:

cd /tmp
npx --yes --package @solana-program/program-metadata@latest \
  program-metadata write idl \
  6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s \
  /tmp/oft_idl.json

You already have the correct authority signer configured (7Qi3WW7...), so once you have the right idl.json, the upload should go through.

Engagement brief

Tuesday, Jun 9, 2026, 5:50 AM (UTC-7) ➜ 4626 git:(main) ✗ # in OFT scaffold repo/workdir export OFT_ID=6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s anchor idl build -p <oft_program_name> > /tmp/oft_idl.json jq '.address, .metadata.name, .metadata.version' /tmp/oft_idl.json zsh: parse error near `>' ➜ 4626 git:(main) ✗

Analysis

That parse error is because <oft_program_name> is placeholder syntax, and zsh treats <...> as redirection tokens.

Use a real program name (no angle brackets), for example:

export OFT_ID=6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s
anchor idl build -p my_oft_program > /tmp/oft_idl.json
jq '.address, .metadata.name, .metadata.version' /tmp/oft_idl.json

If you don’t know the program name yet, in the OFT repo run:

cat Anchor.toml

Look under [programs.mainnet] (or [programs.devnet]) for the key name to use with -p.

Also: you’re currently in 4626 repo, not the OFT scaffold repo, so make sure to cd into the scaffold first before building.

Engagement brief

Tuesday, Jun 9, 2026, 5:50 AM (UTC-7) can you fix it for me

I found the blocker: LayerZero’s OFT IDL generates a placeholder address string via program_id_from_env, so Anchor doesn’t emit 6ste... directly. I’m applying the standard fix now—set .address to your real program ID in the JSON, then upload that file on-chain.

So both are now done for 6ste...:

Explorer may take a short cache refresh window, but the on-chain metadata is now present.

Solana Verified Builds

This repository demonstrates how to implement verified builds for Solana programs. Verified builds ensure that your deployed program matches exactly with your public source code, promoting transparency and security in the Solana ecosystem.

What are Verified Builds?

Verified builds allow developers and users to verify that a deployed Solana program matches its source code. This verification:

Ensures program authenticity
Promotes transparency
Builds user trust
Makes source code discoverable

Quick Start

Install prerequisites:
- Docker
- Cargo
- Solana Verify CLI (cargo install solana-verify --locked)

For production use, prefer installing from a tagged release.

Build your program:

solana-verify build

For programs that don't depend on solana-program (e.g. SDK v3 or pinocchio), add the Solana CLI version in your root Cargo.toml so the tool can pick the right build image:

[workspace.metadata.cli] solana = "3.0.0"

The tool checks this first, then falls back to Cargo.lock (solana-program, solana-program-error, or solana-account-info).

Deploy and verify:

Deploy

solana program deploy -u $NETWORK_URL target/deploy/$PROGRAM_LIB_NAME.so --program-id $PROGRAM_ID

Verify against repository -> upload your build data on chain

solana-verify verify-from-repo -u $NETWORK_URL --program-id $PROGRAM_ID https://github.com/$REPO_PATH

Trigger a remote job

solana-verify remote submit-job --program-id $PROGRAM_ID --uploader $THE_PUBKEY_THAT_UPLOADED_YOUR_BUILD_DATA

The legacy --remote flag on verify-from-repo has been deprecated. Upload your PDA with programs upgrade authority, then run the remote submit-job command to queue OtterSec's worker. For a full walkthrough of the PDA workflow, see the Solana verified builds guide.

Documentation

For detailed instructions and best practices, please refer to the official Solana documentation on verified builds.

Security Considerations

While verified builds enhance transparency, they should not be considered a complete security solution. Always:

Review the source code
Use trusted build environments
Consider using governance solutions for program upgrades

Current Verification Scope

Build images are selected by pinned digest.
Solana/Agave installer scripts in generated Dockerfiles are checksum pinned.
Post-install verification of installed toolchain/platform-tools is still follow-up work.

For responsible disclosure of bugs related to verified builds CLI, please email maintainers@ellipsislabs.xyz with a detailed description of the attack vector.

Contributing

Contributions are welcome! Please feel free to submit a Pull Request.

Releasing

Use .github/workflows/release.yml (Release) as the canonical release path. Use .github/workflows/build.yml only for manual artifact builds from a specific ref.

See RELEASE.md for release steps and recovery procedures.

</external_links> Tuesday, Jun 9, 2026, 5:58 AM (UTC-7) is there any thing else we need to do on solana? https://github.com/solana-foundation/solana-verifiable-build

Program IDL This program doesn't have an IDL yet. If you're the developer, upload it using the instructions below. Upload IDL Use this command to upload generated idl in JSON format

npx @solana-program/program-metadata@latest write idl $PROGRAM_ID ./idl.json In case you want to upload IDL with a multisig, follow the documentation.

Analysis

Short answer: no blocking Solana metadata work left from what you asked.

What’s already done:

6ste... has security metadata uploaded.
6ste... now has idl metadata uploaded.
Ejpzi... has idl metadata uploaded.

If Explorer still says “no IDL,” it’s usually cache lag—wait a bit and hard refresh.

If you want to go beyond metadata, the main next step is Verified Builds (recommended for trust/discoverability), using Solana’s verifier CLI: solana-verifiable-build.

Typical flow:

Build deterministically with solana-verify build
Verify + upload build data:
- solana-verify verify-from-repo -u <rpc> --program-id <PROGRAM_ID> <repo-url>
Optionally trigger remote verification job:
- solana-verify remote submit-job --program-id <PROGRAM_ID> --uploader <pubkey>

So: metadata is complete; verified-build attestation is the remaining “nice-to-have” security/transparency step.

Engagement brief

Tuesday, Jun 9, 2026, 5:59 AM (UTC-7) yes

Analysis

Perfect — I’ll run the verified-build flow now and tell you exactly what passes vs what still needs setup. I’ll start by checking solana-verify availability and command syntax, then run it for your deployed Solana programs.

Progress update: verification failed only because the verifier expects a Cargo.lock in the mounted build path. I’m rerunning it mounted to programs/creator-share-hook (which has its own Cargo.lock) so this should be the correct config.

Tools invoked: Shell

Analysis

I hit a real verifier toolchain mismatch, but there’s one likely fix before we stop: force the verifier build to use Cargo.lock with --locked so it doesn’t pull newer wincode. I’m trying that now.

Tools invoked: Shell

Analysis

Ran this for you, and here’s the outcome:

Status

Program metadata tasks are complete (security + idl uploaded for your target programs).
Verified build is the only remaining optional trust step, but it currently fails due toolchain mismatch in the verifier container.

What failed (important)

solana-verify verify-from-repo gets to build stage, then fails on:

wincode-0.5.1 requires edition2024
verifier build path still uses Cargo in the Solana build stack that can’t handle that edition

So this is not your signer/program setup anymore — it’s a verifier image/toolchain compatibility issue.

Recommended next move

Keep current state as-is (you’re already good for Explorer metadata).
Retry verified-build when a compatible verifier image/toolchain is available (or use a custom verifier base image with newer platform-tools/Cargo, if you want me to wire that path next).

Reference you shared (correct tool/docs): solana-foundation/solana-verifiable-build

If you want, I can do the “custom base image” route next and try to force verification through with an updated container.

npx @solana-program/program-metadata@latest write idl $PROGRAM_ID ./idl.json

Analysis

Great question. Here’s the practical path.

What “Verified Build” needs

You must prove the on-chain binary for a program matches a public repo + exact commit used to build/deploy it, via solana-verify (PDA upload + optional remote job) (solana-verifiable-build).

1) Prereqs

cargo install solana-verify --locked
solana address

Use the upgrade authority signer (you already have 7Qi3... active).

2) Verify from repo (per program)

A) `creator_share_hook` (`Ejpzi...`) in this repo

solana-verify verify-from-repo \
  --current-dir \
  --program-id EjpziSWGRcEiDHLXft5etbUtcJiZxEttkwz1tqiuzzWU \
  --library-name creator_share_hook \
  --mount-path programs/creator-share-hook \
  --workspace-path programs/creator-share-hook \
  https://github.com/wenakita/4626

B) OFT program (`6ste...`)

Run against the actual OFT source repo + commit used for deployment (not this monorepo unless that’s where it lives):

solana-verify verify-from-repo \
  --program-id 6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s \
  --library-name oft \
  --mount-path programs/oft \
  --workspace-path . \
  https://github.com/<your-oft-repo>

3) Submit remote verification job (optional but recommended)

After successful verify-from-repo PDA upload:

solana-verify remote submit-job \
  --program-id <PROGRAM_ID> \
  --uploader <YOUR_SIGNER_PUBKEY>

Current blocker I hit for you

Your verify flow is currently failing on a toolchain/dependency mismatch (wincode edition2024 requirement in verifier build context). That’s why you still see “Program Not Verified” despite metadata being uploaded.

If you want, I can do the next pass to resolve that specifically (custom verifier base image / dependency pin path), then rerun both program verifications end-to-end.

We already uploaded IDL for 6ste... and Ejpzi...; Explorer can lag. If it still shows missing, verify directly:

npx --yes --package @solana-program/program-metadata@latest program-metadata fetch idl 6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s
npx --yes --package @solana-program/program-metadata@latest program-metadata fetch idl EjpziSWGRcEiDHLXft5etbUtcJiZxEttkwz1tqiuzzWU

Engagement brief

Tuesday, Jun 9, 2026, 6:21 AM (UTC-7) can you do it for me

Analysis

Yes — I’m on it. I’ll run the verified-build flow myself and keep pushing until it either verifies or we isolate the exact blocker with a concrete workaround. First I’m checking which verifier image/toolchain we need to avoid the Cargo edition mismatch.

Yes—I did it for you, and here’s where we landed.

What I completed

1) Verified-build local proof + on-chain upload for `Ejpzi...` (creator share hook)

I successfully ran solana-verify verify-from-repo with a newer verifier base image and got:

Repo hash == on-chain hash ✅
76bebcd7d38bd765a0905d78bc02df02eeffc8113396e86109162082d4d0a54c
Verification params uploaded on-chain ✅

PDA record exists ✅ (solana-verify get-program-pda --program-id Ejpzi...)

So cryptographically, this program is verified locally and proof is on-chain.

2) Remote verifier job (`osec.io`) for `Ejpzi...`

I submitted the remote job, but it returned failed:

This is likely why Explorer still shows “Program Not Verified” even though local verification succeeded.

3) `6ste...` OFT program

I attempted solana-verify for 6ste..., but that source builds with a stack offset error during verifier build (LzReceive::try_accounts frame > 4096), so remote verification can’t complete in current source state.

What this means for you

No missing setup on your signer/authority side — that’s all good.
For Ejpzi..., we have a valid local verification + uploaded PDA evidence.
The remaining blocker is remote service acceptance/job success (and for 6ste..., source build constraints in verifier env).

Fastest next step

Open the job log URL above and share the exact failure line; I’ll give you the precise final command/flag tweak to get the remote badge to flip.

Engagement brief

Tuesday, Jun 9, 2026, 6:30 AM (UTC-7) can you do it for me

Perfect — I’ll do exactly that: create a public minimal repo under 4626fun with only what Solana verification needs, then rerun verification against that URL.

What I did

Found root cause: remote verifier couldn’t clone your private repo.

Re-ran solana-verify verify-from-repo against that public repo for:

Re-submitted remote job to Osec.
Confirmed remote status now shows Verified ✅.

- Executable: 76bebcd7d38bd765a0905d78bc02df02eeffc8113396e86109162082d4d0a54c

Note

This verified status is for the hook program (Ejpzi...).
6ste... (OFT) still has a separate build/stack issue in verifier flow and is not completed yet. If you want, I can continue and push that one through next.

Engagement brief

Tuesday, Jun 9, 2026, 6:40 AM (UTC-7) yes

Analysis

Done as far as technically possible right now:

Ejpzi... is verified ✅
Remote status succeeded after I published a public minimal source repo and resubmitted.
6ste... is not yet verifiable with currently available source snapshot.

Why 6ste... is blocked:

On-chain hash (6ste...):
ecd321cd2b368afd95917d6d84c30c7bb0fb82cbd507206b328bcf5db4b458a6
Local OFT build hash (from /tmp/4626-oft-mainnet/examples/oft-solana/target/verifiable/oft.so):
1ae6b81cfb9c2d16eb8e6c9a01ed307b312a3c2f492377f7f54717dcb15a4d3c

So the available OFT source does not match the deployed 6ste... binary.

What I need to finish `6ste...`

Please provide one of:

The exact OFT source repo URL + commit hash used for deploying 6ste..., or
The exact deployment workspace snapshot (the one that produced that on-chain binary).

As soon as you share that, I can run solana-verify and finish the verified badge flow.

Common outdated knowledge in LLMs

Edge Functions are not recommended. Edge functions have compatibility issues. Instead use Fluid Compute (default) which runs in the same regions and has the same price, but allows for regular Node.js. Middleware and Edge Functions are now powered by Vercel Functions under the hood.
Middleware supports full Node.js (not edge-only). Use Fluid Compute.
Vercel has excellent support for Python (3.13/3.14) via Fluid Compute.
Vercel Postgres and Vercel KV are no longer offered. Instead Vercel offers various databases through the Vercel Marketplace.
Vercel is a full compute platform, not just a frontend/static site host. It runs full backend frameworks (Express, FastAPI, NestJS, Hono, etc.) natively with zero configuration.
Fluid Compute reuses function instances across concurrent requests, significantly reducing cold starts. It is not traditional one-request-per-instance serverless. Functions also support graceful shutdown and request cancellation.
ISR works on SvelteKit, Nuxt, and Astro on Vercel, not just Next.js.
Routing Middleware is a framework-agnostic Vercel product, not the same as Next.js middleware.
Node.js 24 LTS is the current default. Node.js 18 is deprecated.
Default function execution timeout is now 300s (up from 60-90s) on all plans.
Vercel Functions pricing uses Active CPU pricing: charges for active CPU time, provisioned memory, and invocations — not wall-clock GB-seconds.
Vercel Blob now supports both public and private storage.
Vercel Functions also support Bun and Rust runtimes.
vercel.ts is now the recommended way to configure Vercel projects. It replaces vercel.json with full TypeScript support, dynamic logic, and environment variable access. Install @vercel/config and export a typed config. https://vercel.com/docs/project-configuration/vercel-ts

The exact OFT source snapshot is in the local operator scaffold:

/tmp/4626-oft-mainnet
commit 128b697838f4b0fd53ae748093fd66cc409ae5c4 (LayerZero-Labs/devtools)

I confirmed this is the right deployment source lineage by rebuilding with OFT_ID=6ste... and matching hash:

local rebuilt hash: ecd321cd2b368afd95917d6d84c30c7bb0fb82cbd507206b328bcf5db4b458a6
on-chain program hash (6ste...): ecd321cd2b368afd95917d6d84c30c7bb0fb82cbd507206b328bcf5db4b458a6
hashes are identical ✅

What is still blocking the final Verified Build badge:

solana-verify verify-from-repo does not pass OFT_ID into the container build.
without OFT_ID, it compiles against default 9Uov... and hits the stack-offset failure path.
this is a tooling limitation in the CLI path, not your program bytes.

Fastest way to finish the badge

Use manual verified-build flow with this exact source snapshot:

What I completed

Created a public minimal verification repo:
- https://github.com/4626fun/oft-solana-6ste-verifiable
Uploaded updated verification metadata PDA for 6ste... from your authority signer.
Submitted remote verification job again.

Current hard blocker (now confirmed)

Remote verifier still fails with hash mismatch:

On-chain hash: ecd321cd2b368afd95917d6d84c30c7bb0fb82cbd507206b328bcf5db4b458a6
osec executable hash: d86b3260659821dd3d2bdfdee4bca10bea2150f1bfe2e40d9a0ff34002bcc86e
job: https://verify.osec.io/job/ec3bf6f4-0537-451d-a92d-d234af7feeed

So the source snapshot is now public and reproducible, but osec’s build pipeline is producing a different binary than the one deployed.

Why this is happening

The deployed binary depends on the OFT ID injection path (OFT_ID) and build context/toolchain details that solana-verify/osec is not reproducing the same way. I verified locally earlier that your deployed hash can be reproduced, but osec’s build path does not match it.

Fastest path to actually get the badge

At this point the next step is an osec/manual-verifier intervention with the evidence we now have:

program id: 6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s

title: Verifying Programs description: Verified builds is a way to link your program to its source code and let everyone independently verify that the program was indeed built from that provided source code.

This guide is meant to be a reference for developers who want to implement verified builds for their programs on Solana. We will cover what verified builds are, how to use them, special considerations, and best practices to ensure the authenticity of your program onchain.

What are verified builds?

Verified builds ensure that the executable program you deploy to Solana’s network matches the source code in your repository. By doing this, developers and users can have confidence that the program running onchain corresponds exactly to the public codebase, promoting transparency and security.

The verification process involves comparing the hash of the onchain program with the hash of the locally built program from the source code. This ensures no discrepancies between the two versions.

While a verified build should not be considered more secure than an unverified build, the build enables developers to self verify the source code matches what is deployed onchain. Using the source code, a developer can then validate what the code executes when sending a transaction.

The verified builds pipeline was thought out and is maintained by Ellipsis Labs and OtterSec. For more details, follow the guide in the original verified builds repository as well and the verify build process directly into the Anza tool suite, once supported there.

How does it work?

The verification process is done by comparing the hash of the onchain program with the hash of the locally built program from the source code. You build your program in a controlled environment using the Solana Verify CLI and Docker. This ensures that the build process is deterministic and consistent across different systems. Once you have the executable, you can deploy it to the Solana network. During the build process a PDA of the verify program will be created. This PDA contains all the data necessary to verify the program. The PDA contains the program address, git url, commit hash and the arguments used to build the program.

Using the data in the PDA everyone can run the verify program command locally and check if the program was built from the provided source code. Then everyone can verify for themselves completely trustlessly or can run their own verify API maintained by OtterSec to provide an easy access point for users to check the verification. You can already see these API calls being used in the Solana Explorer and SolanaFM, among other places.

Why should I use verified builds?

Using verified builds provides the following benefits:

Security: Guarantee that the program running onchain matches the source code, preventing malicious alterations.
Transparency: Allows other users and developers to validate that the onchain program is trustworthy by comparing it with the public codebase.
Trust: Increase user confidence, as verified builds demonstrate that your program's onchain behavior is aligned with your public code. When building verifiable programs, you minimize risks associated with running unauthorized or malicious code. It also ensures you comply with best practices and give security researchers an easy way to contact you. Also wallets and other tools can allow transactions from your program more easily as long as it is verified.
Discoverability: When you provide a verified build of you program everyone can find your source code, docs, program SDK or IDL and they can also easily contact you via github in case there is an issue.

How do I create verified builds?

To create verified builds, you'll need to follow these steps:

Summary:

Commit your code to a public repository
Build a verified build in docker
Deploy the verified build
Verify the deployed program against public API

If you verify your program which is not build in a docker container it will most likely fail because Solana program builds are not deterministic across different systems.

Install Docker and Cargo

Install the necessary tools ensure you have Docker and Cargo installed. Docker provides a controlled build environment to ensure consistency, and Cargo is used for managing Rust packages.

Docker: Follow the steps on the Docker website to install Docker for your platform. Once installed, ensure the Docker service is running following this guide further.
Cargo: If you don’t already have Cargo installed, you can install it by running the following command:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Install the Solana Verify CLI

The Solana Verify CLI is the primary tool used to verify builds. Solana Verify CLI is currently maintained by Ellipsis Labs and can be installed using Cargo.

You can install it by running:

cargo install solana-verify

If you need a specific version of the CLI, you can pin the version with:

cargo install solana-verify --version $VERSION

If desired, you can install a version directly from a specific commit:

cargo install solana-verify --git https://github.com/Ellipsis-Labs/solana-verifiable-build --rev 13a1db2

Prepare project

To verify against a repository it needs to have a Cargo.lock file in the root directory of your repository. If you only have one program in your repository and a cargo.lock file in your root you can directly go to the next step and build your program.

If your program is in a subfolder and you have a rust workspace you need to create a workspace Cargo.toml file in the root directory of your repository.

You can use this Cargo.toml example as a preset:

Cargo.toml
[workspace]
members = ["program/programs/*"]
resolver = "2"

[profile.release]
overflow-checks = true
lto = "fat"
codegen-units = 1

[profile.release.build-override]
opt-level = 3
incremental = false
codegen-units = 1

Make sure that your program is in the workspace/members array and that the Cargo.toml of your program has the correct lib name configured.

Important is the lib name not the package name!

Something like this:

waffle/Cargo.toml
[package]
name = "waffle"
version = "0.1.0"
edition = "2021"

[lib]
name = "waffle"
crate-type = ["cdylib", "lib"]

[dependencies]
solana-program = "2.1.0"

In this repository you can see an example of a workspace with a program in a subfolder. Notice also that when the program is in a subfolder you later need to add this folder as --mount-path to the verify-from-repo command.

In this repository you can find an anchor example. In this repository you can find a native rust example.

With this Cargo.toml file in place you can then run cargo generate-lockfile to create a lock file and continue to building your program.

Building Verifiable Programs

To verifiably build your Solana program, navigate to the directory containing your workspace's Cargo.toml file and run:

solana-verify build

This will copy your environment into a docker container and build it in a deterministic way.

Make sure that you actually deploy the verified build and don't accidentally overwrite it with anchor build or cargo build-sbf since these will most likely not result into the same hash and though your verification will fail.

For projects with multiple programs, you can build a specific program by using the library name (not the package name):

solana-verify build --library-name $PROGRAM_LIB_NAME

This process ensures deterministic builds and can take some time, especially on certain systems (e.g., M1 MacBook) because it is running within a docker container. For faster builds, using a Linux machine running x86 architecture is recommended.

Once the build completes, you can retrieve the hash of the executable using the following command:

solana-verify get-executable-hash target/deploy/$PROGRAM_LIB_NAME.so

Deploying Verifiable Programs

Once you have built your program and retrieved its hash, you can deploy it to the Solana network. It is recommended to use a multi-signature or governance solution like Squads Protocol for safe deployments, but you can also directly deploy with:

solana program deploy -u $NETWORK_URL target/deploy/$PROGRAM_LIB_NAME.so --program-id $PROGRAM_ID --with-compute-unit-price 50000 --max-sign-attempts 100 --use-rpc

A currently fitting low priority fee you can request from your rpc provider for example Quicknode.

To verify the deployed program matches the built executable, run:

solana-verify get-program-hash -u $NETWORK_URL $PROGRAM_ID

You may have different versions deployed on different Solana clusters (i.e. devnet, testnet, mainnet). Ensure you use the correct network URL for the desired Solana cluster you want to verify a program against. Remote verification will only work on mainnet.

Verifying against repositories

To verify a program against its public repository, use:

solana-verify verify-from-repo -u $NETWORK_URL --program-id $PROGRAM_ID https://github.com/$REPO_PATH --commit-hash $COMMIT_HASH --library-name $PROGRAM_LIB_NAME --mount-path $MOUNT_PATH

While you run the verified build in your program directory, when running verify-from-repo you need to add the --mount-path flag. This will be the path to the folder containing the Cargo.toml that contains your program's library name.

This command compares the onchain program hash with the executable hash built from the source at the specified commit hash.

At the end the command will ask you if you want to upload your verification data onchain. If you do that the Solana Explorer will immediately show your program's verification data. Until it was verified by a remote build it will show as unverified. Learn how you can verify your program against a public API in the next step.

If you want to lock the verification to a certain release, you can append the --commit-hash flag to the command.

Verify against public API

Finally you can also directly verify the program against anyone that is running the verify API::

solana-verify verify-from-repo --remote -um --program-id PhoeNiXZ8ByJGLkxNfZRnkUfjvmuYqLR89jjFHGqdXY https://github.com/Ellipsis-Labs/phoenix-v1

It is recommended to use a payed RPC Url because otherwise you may run into rate limits of the free RPCs. So instead of -um you should use --url yourRpcUrl for a more reliable verification.

The --remote flag sends a build request to the OtterSec API, which triggers a remote build of your program. Once the build is complete, the system verifies that the onchain hash of your program matches the hash of the generated build artifact from your repository.

The default is the OtterSec API.

Make sure to pick yes when you are asked to upload the verification data onchain. This is used by the API to verify that you uploaded the verification data.

You can also trigger a remote job manually by using:

solana-verify remote submit-job --program-id <program-id> --uploader <address>

Where the uploader is the address that has the authority to write to the PDA. That should be program authority in most cases. If your program is controlled by a multisig please continue in the multisig verification part of this guide below.

This will submit a job to the OtterSec API and you can then verify the job status with:

solana-verify remote get-job-status --job-id <job-id>

Once the verification has completed successfully, which may take awhile, you will be able to see your program as verified in the OtterSec API for single programs and in the Solana Explorer, SolanaFM, SolScan and eventually also on the community-run website SolanaVerify.org maintained by 0xDeep and the OtterSec verified programs API and at last in the Verified Programs Dune Dashboard contributing to a more healthy Solana ecosystem.

How to verify your program when its controlled by a Multisig like Squads

For the remote verification to work you need to write the verification data into a PDA signed by the program authority. If your program is controlled by a multisig you can export this write PDA transaction and submit it through Squads Protocol or another multisig solution of your choice.

1. Build the verifiable program

First build the program:

solana-verify build

This will build a verifiable build using a docker container using the solana version specified in the Cargo.lock file.

2. Deploy the program

solana config set --url "PayedMainnetRPCAddress" // the public endpoint will be rate limited too much
solana program deploy target/deploy/verify_squads.so

For the rest of this multisig guide, we will use an example program ID of 6XBGfP17P3KQAKoJb2s5M5fR4aFTXzPeuC1af2GYkvhD.

3. Commit and verify against repository

Once that is done we commit the project to to github. Here is an example: https://github.com/solana-developers/verify-squads

Optional: See if you can verify locally first (this command uses example program ID 6XBGfP17P3KQAKoJb2s5M5fR4aFTXzPeuC1af2GYkvhD):

solana-verify verify-from-repo https://github.com/solana-developers/verify-squads --program-id 6XBGfP17P3KQAKoJb2s5M5fR4aFTXzPeuC1af2GYkvhD

Just to make sure your parameters are correct.

4. Transfer program authority to multisig

If you have not yet transfer your programs authority to the multisig and copy the multisig authority. You need it in the next step.

5. Export PDA transaction

When you have you program authority locally you are prompted to upload the build data onchain when using the command solana-verify verify-from-repo.

Since you can not do that when you are using a multisig you need to export the PDA transaction manually and then trigger the transaction through Squads.

solana-verify export-pda-tx https://github.com/solana-developers/verify-squads --program-id 6XBGfP17P3KQAKoJb2s5M5fR4aFTXzPeuC1af2GYkvhD --uploader <your program authority> --encoding base58 --compute-unit-price 0

This will return you a base58 transaction. If you want a base64 encoded transaction for use in a transaction inspector, you can use --encoding base64.

6. Submit transaction through Squads

Go to the squads transaction builder and import the base58 encoded transaction. Make sure that in the simulation the transaction only has a call to the osec verify program and the computer budget program and nothing else!

7. Submit remote verification job

Once the transaction to squads was successful you can submit the remote job:

solana-verify remote submit-job --program-id 6XBGfP17P3KQAKoJb2s5M5fR4aFTXzPeuC1af2GYkvhD
--uploader <your program authority>

This is it! You have verified your program against a public repository and submitted a remote job to the OtterSec API. You should be able to see it reflect in the solana explorer and other places now.

8. Updating the program (Optional)

When you update your program you need to export a new PDA transaction and submit it through Squads again.

Doing an update to the program:

solana-verify build
solana program write-buffer target/deploy/verify_squads.so --with-compute-unit-price 50000 --max-sign-attempts 50

Then transfer that buffer authority to the multisig or directly create the buffer with the authority of the multisig.

solana program set-buffer-authority Fu3k79g53ZozAj47uq1tXrFy4QbQYh7y745DDsxjtyLR --new-buffer-authority 3JG6ULvZVCrkKtSSskKNJGe8RNZGFe8Ruev9KUhxzK5K

9. Export and submit new PDA transaction

Don't forget to commit your changes to github. Export the PDA upgrade transaction again:

solana-verify export-pda-tx https://github.com/solana-developers/verify-squads --program-id 6XBGfP17P3KQAKoJb2s5M5fR4aFTXzPeuC1af2GYkvhD --uploader 3JG6ULvZVCrkKtSSskKNJGe8RNZGFe8Ruev9KUhxzK5K

Submit the transaction through Squads again.

You can see an example transaction here.

Then submit for another remote build:

solana-verify remote submit-job --program-id 6XBGfP17P3KQAKoJb2s5M5fR4aFTXzPeuC1af2GYkvhD --uploader 3JG6ULvZVCrkKtSSskKNJGe8RNZGFe8Ruev9KUhxzK5K

Should result in something like this:

You can also verify your program against a docker image by running the following command:

solana-verify verify-from-image -e
examples/hello_world/target/deploy/hello_world.so -i
ellipsislabs/hello_world_verifiable_build:latest -p
2ZrriTQSVekoj414Ynysd48jyn4AX6ZF4TTJRqHfbJfn

This command loads up the image stored at ellipsislabs/hello_world_verifiable_build:latest, and verifies that the hash of the executable path in the container is the same as the hash of the onchain program supplied to the command. Because the build was already uploaded to an image, there is no need for a full rebuild of the executable which can take a long time.

The Dockerfile that creates the image ellipsislabs/hello_world_verifiable_build:latest can be found in the ellipsis labs repository /examples/hello_world.

Below is the expected output:

Verifying image: "ellipsislabs/hello_world_verifiable_build:latest", on network
"https://api.mainnet.solana.com" against program ID
2ZrriTQSVekoj414Ynysd48jyn4AX6ZF4TTJRqHfbJfn Executable path in container:
"examples/hello_world/target/deploy/hello_world.so"

Executable hash:
08d91368d349c2b56c712422f6d274a1e8f1946ff2ecd1dc3efc3ebace52a760 Program hash:
08d91368d349c2b56c712422f6d274a1e8f1946ff2ecd1dc3efc3ebace52a760 Executable
matches onchain program data ✅

Example verified build

Here’s an example of verifying an example program with the ID FWEYpBAf9WsemQiNbAewhyESfR38GBBHLrCaU3MpEKWv using the source code from this repository:

solana-verify verify-from-repo https://github.com/solana-developers/verified-program --url YOUR-RPC-URL --program-id FWEYpBAf9WsemQiNbAewhyESfR38GBBHLrCaU3MpEKWv --mount-path waffle --library-name waffle --commit-hash 5b82b86f02afbde330dff3e1847bed2d42069f4e

By default the verify-from-repo command takes the last commit on the main branch. You can also define a certain commit in case you want to continue working on the repository by using the commit-hash parameter: --commit-hash 5b82b86f02afbde330dff3e1847bed2d42069f4e

Finally you can also directly verify the program against the OtterSec API:

solana-verify verify-from-repo https://github.com/solana-developers/verified-program --url YOUR-RPC-URL --remote --program-id FWEYpBAf9WsemQiNbAewhyESfR38GBBHLrCaU3MpEKWv --mount-path waffle --library-name waffle --commit-hash 5b82b86f02afbde330dff3e1847bed2d42069f4e

The --remote command sends a build request to the OtterSec API, which triggers a remote build of your program. Once the build is complete, the system verifies that the onchain hash of your program matches the hash of the generated build artifact from your repository.

Frequently asked questions

My verification is failing. What should I do?

Check these common issues:

Wrong signer: Confirm your signer is the program's upgrade authority by running solana program show YourProgramId
No onchain PDA: Run solana-verify verify-from-repo -um and select YES when prompted. Without uploading the PDA, the API can't retrieve your verification metadata.
PDA data mismatch: Update your PDA if you've redeployed your program. Your PDA data must match your deployed program.
Incorrect commit hash: Create your PDA using the exact commit hash you deployed
Build environment differences: Use Docker with solana-verify when creating your PDA

My local build hash doesn't match the onchain hash. Why?

This usually means:

You're using different Rust/Solana toolchain versions
Your dependencies were updated between builds
You didn't build in a Docker container
You checked out the wrong commit

Fix this by building with solana-verify build in Docker using the exact commit you deployed.

How long will my verification take?

Expect these timeframes based on your program size:

Simple programs: 1-5 minutes
Complex programs: 5-15 minutes
Very large programs: Up to 30 minutes

Track your progress using the job status endpoint.

My program is immutable (no upgrade authority). How can I verify it?

If your program has no upgrade authority or was made immutable before you could create a PDA, we have a whitelisted address for this situation. Contact us at contact@osec.io, and we'll help you get your program verified.

What is the PDA and why does it matter?

Your PDA (Program Derived Account) enables trustless verification:

On-Chain Storage: Store your verification metadata (repo URL, commit hash, build params) onchain in a PDA owned by the Otter Verify program (verifycLy8mB96wd9wqq3WDXQwM4oU6r42Th37Db9fC)
Cryptographic Link: Your PDA is derived from your program address, creating an immutable link to your verification data
Decentralized Trust: Anyone can read your PDA and independently verify your program

Why must I create the PDA before using the API?

The API only works with onchain PDAs because:

Trustless: The API rejects arbitrary data - it only uses what your upgrade authority stored onchain
Simpler: Just provide signer + program_id; the API gets everything else from your PDA
Tamper-Proof: Your PDA creates an immutable record anyone can verify independently
Ownership Proof: Your signer must be the upgrade authority, cryptographically proving you control the program

How often should I verify my program?

Verify your program:

After every deployment or upgrade
When you update your source repository
Don't worry about re-verifying otherwise - the API automatically re-verifies all programs every 24 hours

What happens when I upgrade my program?

Follow these steps after upgrading:

The API detects your upgrade and unverifies your program.
Update your PDA with new verification metadata:

solana-verify verify-from-repo -um \
  --program-id YourProgramId... \
  https://github.com/your-org/your-program

Submit a new verification request using your upgrade authority
The API will verify your new version against the updated PDA

Important: Always update your PDA using your upgrade authority with the new commit hash for the upgraded program.

Can I trust the verification results?

Yes - the system is designed to be trustless and independently verifiable:

What Makes It Trustworthy:

On-Chain PDA: Your verification metadata lives onchain, not controlled by any central authority
Upgrade Authority Proof: Only your program's upgrade authority can create/update the PDA
Independent Verification: Anyone can verify by reading your PDA and running solana-verify locally
Continuous Re-verification: The API automatically re-verifies all programs every 24 hours

Understand These Limitations:

Verification confirms source matches deployment - NOT that your code is secure
Always review code before interacting with programs
Verified ≠ audited, or safe
Check the repository and commit in the PDA to confirm it's from a trusted source

How can I independently verify a program?

Verify any program yourself by reading its onchain PDA and running verification locally:

Step 1: Read the On-Chain PDA

# Install solana-verify if you haven't
cargo install solana-verify

# Get the PDA data
solana-verify list-program-pdas --program-id YourProgramId...

Step 2: Verify Locally

# Verify using the repository and commit & other arguments from the PDA
solana-verify verify-from-repo \
  --program-id YourProgramId... \
  https://github.com/your-org/your-program
  --commit-hash <commit-hash>
  ... (other arguments from the PDA)
# Confirm the hash output matches the onchain program hash

This proves:

The PDA metadata is authentic (stored onchain)
The source code in the PDA's repository matches the deployed program
You don't need to trust the API - verify everything yourself onchain

Can someone else verify my program without permission?

Yes, that's the reason why we require the signer to be the upgrade authority. We only consider the verification to be valid if the signer is the upgrade authority.

What do I need to create verifiable builds?

Install these tools:

Docker (for deterministic builds)
Cargo (Rust package manager)
Solana Verify CLI: cargo install solana-verify
A public Git repository with your source code

Can I verify private repositories?

No - verification requires public source code:

Your PDA stores a public repository URL that anyone can access
Trustless verification depends on public code access
Users need to read your source code to understand what your program does
The entire purpose is to let users independently verify source matches deployment

Private repositories break the verification system's core trust model.

How do I verify a program controlled by Squads Multisig?

Follow these steps for multisig-controlled programs:

# 1. Build and deploy normally
solana-verify build
solana program deploy <your-program.so> --program-id YourProgramId...

# 2. Verify locally first - confirm the hash matches
solana-verify verify-from-repo -um \
  --program-id YourProgramId... \
  https://github.com/your-org/your-program

# 3. Export the PDA creation transaction
solana-verify export-pda-tx \
  --program-id YourProgramId... \
  https://github.com/your-org/your-program

# 4. Execute the PDA transaction through your Squads Multisig interface

# 5. After multisig execution, trigger remote verification
solana-verify remote submit-job \
  --program-id YourProgramId... \
  --uploader YourMultisigAddress...

Critical: Always verify locally (step 2) to confirm the build hash matches before exporting the PDA transaction.

Conclusion

Using verified builds on Solana ensures the integrity and trustworthiness of your programs on the network and allow developers to find your SDKs directly from a Solana Explorer. By leveraging tools like the Solana Verify CLI and Docker, you can maintain verifiable and secure builds that align with your source code. Always take the necessary precautions to use consistent environments, and consider governance solutions for safe upgrades and deployments.

Security + Disclaimer

While verified builds are a powerful tool for ensuring the integrity of your Solana programs it is not completely trustless in the default setup. The docker images are built and hosted by the Solana Foundation.

Be aware that you are building your project in a downloaded docker image and that your whole setup gets copied into that docker image for building including potentially sensitive information.

If you want to have a completely trustless setup you can build the docker images yourself and host them on your own infrastructure. This way you can be sure that the docker images are not tampered with. You can find the scripts to create your own docker images in the Verified builds repository and you can fork it and run the github actions yourself or validate that they are correct.

Furthermore for the remote verification you are trusting the OtterSec API and the Solana Explorer to a certain degree.

The API or Solana Explorer may potentially display incorrect information if compromised.

If you want to have a completely trustless setup you can run the Verify API yourself or run the program verification locally yourself using the verify-from-repo command using the on chain verify data that is saved in a PDA that is derived from the programs deploy authority and the verify program.

The verify program is deployed by the OtterSec team and is not yet frozen so it can be upgraded at any time.

The Solana Foundation, OtterSec and the Ellipsis Labs team are not responsible for any losses or damages that may occur from using the verified builds pipeline.

Security.txt for Solana programs

In addition to verified builds you can also add a security.txt file to your program. In the future, once implemented, the security.txt will hold the verifier public key for easy access to the verification data stored in the verification PDA. The PDA containing all the information needed to build and verify a program is derived from the programs address and the verifier pubkey. By default this is the same pubkey that built and deployed the program. But it can also be another pubkey that can be specified in the security.txt.

The security.txt feature allows developers to embed contact and security information directly within their Solana smart contracts. Inspired by securitytxt.org, this approach provides a standardized way for security researchers to reach out to project maintainers, even if they only know the contract's address.

Why use security.txt?

For many projects, especially smaller or private ones, identifying the developers from just the contract address can be difficult and time-consuming. Embedding a security.txt file within the program ensures that security researchers can easily contact the correct people, potentially preventing exploits and ensuring timely bug reports.

How to implement security.txt

To add a security.txt to your Solana program, include the following steps:

Add the solana-security-txt dependency to your Cargo.toml:

Cargo.toml
[dependencies]
solana-security-txt = "1.1.1"

Use the security_txt! macro in your contract to define your security information. You can include contact details, project URLs, and even a security policy. Here's an example:

#[cfg(not(feature = "no-entrypoint"))]
use {default_env::default_env, solana_security_txt::security_txt};

#[cfg(not(feature = "no-entrypoint"))]
security_txt! {
    name: "MyProject",
    project_url: "https://myproject.com",
    contacts: "email:security@myproject.com,discord:security#1234",
    policy: "https://myproject.com/security-policy",

    // Optional Fields
    preferred_languages: "en,de",
    source_code: "https://github.com/solana-developers/solana-game-preset",
    source_revision: "5vJwnLeyjV8uNJSp1zn7VLW8GwiQbcsQbGaVSwRmkE4r",
    source_release: "",
    encryption: "",
    auditors: "Verifier pubkey: 5vJwnLeyjV8uNJSp1zn7VLW8GwiQbcsQbGaVSwRmkE4r",
    acknowledgements: "Thank you to our bug bounty hunters!"
}

Once the security.txt information is embedded in your program, it can be easily queried via tools like the Solana Explorer, ensuring that your contact and security details are available to anyone looking to report potential issues.

Best practices

Use Links: For information likely to change (e.g., contact details), it's recommended to link to a web page rather than hard-coding them into the contract. This avoids the need for frequent program upgrades.
Verification: Before deploying, verify the format and content using the query-security-txt tool, which can validate both onchain programs and local binaries:

query-security-txt target/bpfel-unknown-unknown/release/my_contract.so

By embedding security contact information directly into your contract, you make it easier for researchers to reach you, fostering better security and communication within the Solana ecosystem.

This is an example of how security.txt looks in the Solana Explorer

The security.txt project is maintained by Neodyme Labs

Analysis

Great paste — this confirms we should lean on strict verify-from-repo repo/workspace layout rules. I’m going to run one more deterministic test using repo root as mount/workspace (not programs/oft) to try to reproduce the on-chain hash exactly.

Current state (authoritative)

For 6ste36Y7fcbzJXkVQj3ApEqYb3wFZsZX63gT6wymhy3s:

PDA exists and is correct:
- Repo: https://github.com/4626fun/oft-solana-6ste-verifiable
- Commit: 2a08d54c1b8f51bff54b40514a18ede8ff6d562c
- Args: ["--mount-path","programs/oft","--workspace-path",".","--library-name","oft"]
- Signer: 7Qi3WW7q4kmqXcMBca76b3WjNMdRmjjjrpG5FTc8htxY
Remote job still fails with mismatch:
- On-chain: ecd321cd...
- Remote built: d86b3260...

Why this still fails

The remote verifier build path is deterministic, but it is not reproducing the exact deploy-time build context that produced ecd321cd... (likely due to environment/input differences around this OFT setup). This is now not a missing-metadata issue; it is a reproducibility mismatch inside the verifier pipeline.

Best next action

Escalate to osec with the exact reproducibility package (PDA address, repo+commit, args, hashes, job URL). I can draft that message in final, copy-paste-ready format now if you want.
