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

​
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

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