SignatureRedeemQueue

Purpose

SignatureRedeemQueue extends SignatureQueue to enable instant share redemption from a vault without the usual delay of on-chain oracle processing. It leverages off-chain consensus signatures conforming to EIP-712 or EIP-1271 to authorize redemptions, allowing trusted users to convert shares to assets in a fast and secure manner.

This module provides a low-latency redemption path under stronger trust assumptions, useful in environments where responsiveness is critical and participants are whitelisted by a governance consensus.

Key Features

  • Off-chain authorized redemptions using signed Order messages

  • Oracle-bound price validation to prevent manipulation

  • EIP-712 structured data signature verification

  • Direct burning of shares and asset pulling from the vault and payout

  • Nonce-based replay protection

  • Vault hook execution and balance tracking

  • No redeem fee applied (unlike possible fees in RedeemQueue)

Function: redeem

function redeem(Order calldata order, IConsensus.Signature[] calldata signatures) external payable nonReentrant

Parameters:

  • order: A signed redemption Order struct specifying asset amount and recipient

  • signatures: Validator signatures from the consensus group

Workflow

  1. Validation via validateOrder(...):

    • Signature freshness (deadline)

    • Queue and asset correctness

    • Caller authenticity and correct nonce

    • Signatures validated by registered Consensus contract

    • Price computed from ordered and requested values and verified via oracle

  2. Nonce incremented for the caller to prevent signature reuse

  3. Vault liquid asset check:

    • Ensures enough liquidity is available for the redemption

    • Reverts with InsufficientAssets if funds are lacking

  4. Redemption Processing:

    • Burns order.ordered shares from the user via shareManager

    • Calls vault.callHook(...) for any strategy exit logic

    • Transfers order.requested assets to the user

    • Updates internal vault balance via the RiskManager

  5. Event Emitted:

    • OrderExecuted(order, signatures) confirms successful execution

Error: InsufficientAssets

error InsufficientAssets(uint256 requested, uint256 available);

Thrown when the vault does not have enough liquid assets to fulfill the request. Ensures safety during instantaneous exits.
