Building Hooks

Hooks add custom logic at protocol events.

Interface

interface IHooks {
    // Term events
    function beforeTermInitialize(address caller, TermKey memory termKey, bytes calldata hookData) external;
    function afterTermInitialize(address caller, TermKey memory termKey, bytes calldata hookData) external;
    function beforeTermModifyPosition(address caller, TermKey memory termKey, TermModifyPositionParams memory params, bytes calldata hookData) external;
    function afterTermModifyPosition(address caller, TermKey memory termKey, TermModifyPositionParams memory params, bytes calldata hookData) external;
    function beforeTermSettle(address caller, TermKey memory termKey, TermSettleParams memory params, bytes calldata hookData) external;
    function afterTermSettle(address caller, TermKey memory termKey, TermSettleParams memory params, bytes calldata hookData) external;

    // Loan events
    function beforeAllocate(address caller, TermKey memory termKey, LoanKey memory loanKey, AllocateParams memory params, bytes calldata hookData) external;
    function afterAllocate(address caller, TermKey memory termKey, LoanKey memory loanKey, AllocateParams memory params, bytes calldata hookData) external;
    function beforeRepay(address caller, TermKey memory termKey, LoanKey memory loanKey, RepayParams memory params, bytes calldata hookData) external;
    function afterRepay(address caller, TermKey memory termKey, LoanKey memory loanKey, RepayParams memory params, bytes calldata hookData) external;
}

Use Cases

Access Control - Whitelist addresses, require KYC Protocol Integration - Connect to Aave, Compound, etc. Custom Logic - Rate limiting, timelocks, custom fees

Built-in Hooks

P2P - Manual loan approval AaveV3 - Idle capital optimization Timelock - Delayed execution

Integration Notes

• Implement the interface above

• All functions are optional

• Reverting blocks the operation

• Reference deployed contracts for implementation details
