ERC-4626 Deviation Note — CreatorOVault

CreatorOVault inherits OpenZeppelin’s ERC4626 and presents a recognizable ERC-4626 share token interface. It is not a pure drop-in implementation.

Intentional Deviations

Area	Standard ERC-4626 Behavior	CreatorOVault Behavior
Large withdrawals	Instant	≥ largeWithdrawalThreshold must go through queueWithdrawal → delay → claimQueuedWithdrawal
Preview functions	Symmetric	previewRedeem subtracts queued shares. previewDeposit / previewMint / previewWithdraw remain vanilla OZ and can be inaccurate when queues or strategies are active
redeem / withdraw	3-argument only	Also exposes 4-argument versions with Yearn-style maxLoss (bps)
Access control	Open	deposit / mint gated by whitelist + pause + shutdown. Exit paths have different guards
totalAssets	asset.balanceOf(address(this))	Includes strategy marks + idle clamp via OVaultViewLib
Virtual shares	Optional	Fixed _decimalsOffset() = 3 (1000 virtual shares) for inflation protection

Integrator Guidance

• Prefer previewRedeem when queued withdrawals may be non-zero.
• Do not assume instant liquidity for large positions.
• Treat this vault as ERC-4626 + protocol extensions, not a vanilla implementation.
• The 4-arg redeem/withdraw overloads are intentional (Yearn-style maxLoss).

Design Stance

The contract is an ABI + storage facade. Core logic lives in modules. Future product features should not be added as new methods on CreatorOVault.
