Fees and lottery
Configured ShareOFT fees, lottery mechanics, and conditional reward routing. Availability depends on the deployment and active integrations.
These mechanics require active, correctly wired integrations. The newly listed AKITA vault was unfunded with no gauge binding at the September 25, 2026 verification block. The documented gauge remains bound to the legacy stack, with voting and voter-distributor addresses unset.
Once a vault is trading live, each buy of its ShareOFT on the Base market does two things: it pays a fee, and it enters an instant lottery.
What counts as a qualifying buy
Only a DEX buy of ShareOFT on the live Base ShareOFT/ETH market qualifies. These do not:
- Wrapping or depositing into the vault
- Receiving ShareOFT over a bridge
- Selling
Where the fee goes
The inspected new ShareOFT had its native buy fee configured to 6.9% (buyFeeBps = 690) at the verification block. The owner can change this rate, subject to the current source cap of 1,000 bps. Fee flags, address classifications, exemptions, and venue configuration determine applicability; it is not a fee on every swap. Sell fees depend on the venue or hook. The current gauge source defines the following allocation proportions, separately from the fee rate:
| Slice | Share of the fee | What it does |
|---|---|---|
| Lottery pot | 69% | Added to the vault's jackpot reserve |
| Voters / protocol | 21.39% | Eligible voters when configured; otherwise the source routes to protocol treasury, or the jackpot if treasury is unset |
| Burn | 9.61% | Unwrapped and burned; the accounting effect depends on remaining vault assets |
Illustration, assuming the full 6.9% fee applies: on a $100 buy, that is $6.90 in fees: about $4.76 to the pot, $1.48 to voters, and $0.66 burned. Most of the fee stays in ShareOFT; only the burn slice is unwrapped.
If vault assets stay unchanged, burning outstanding vault shares can increase accounted creator-coin units per remaining share. This does not guarantee a higher market price, a dollar gain, or liquid redemption. Strategy losses, creator-coin price changes, and fees can outweigh that effect. Income and fees can be zero. Qualified creator earnings can flow into a vault only where the relevant routing is configured.
How the lottery works
Every qualifying buy is a lottery ticket. Chainlink VRF draws a random number for each one.
- If you win, you receive 69% of the pot, paid in ShareOFT from the vault's gauge.
- If you don't, the pot keeps growing for the next buyer.
The fee split sends 69% of each fee to the pot. A win pays out 69% of the pot (6900 bps of the pot). They happen to share a number but measure different things.
Your odds
Your chance of winning grows with the size of your buy, up to a cap. The pot's size does not change your odds.
| Buy size | Chance to win |
|---|---|
| $100 | 0.04% |
| $1,000 | 0.4% |
| $10,000 or more | 4% (the cap) |
In plain terms, your chance is your buy in USD divided by 250,000, capped at 4%. Onchain this is BasePPM = min(swapUSD / 250_000, 40_000), in parts per million (40,000 ppm = 4%). Tickets that come from Solana are scaled by 400/690, which only adjusts the odds; it is not a second fee.
