Functions​

createSession​

Create a new agent session.

function createSession(
    address vault,
    address agent,
    uint256 expiresAt,
    uint256 dailyLimitUSD,
    uint256 perTxLimitUSD,
    uint8 maxPositionSizePct,
    uint16 maxSlippageBps,
    uint8 maxLeverage,
    bytes4[] calldata allowedOperations,
    address[] calldata allowedProtocols
) external

validateOperation​

Validate and record an operation (called by vault).

function validateOperation(
    address vault,
    address agent,
    address target,
    uint256 valueUSD,
    bytes4 operation
) external returns (bool)

getSession​

Get session details.

function getSession(
    address vault,
    address agent
) external view returns (AgentSession memory)

revokeSession​

    address vault,
    address agent
) external

Session Structure​

struct AgentSession {
    address agent;
    uint256 expiresAt;
    uint256 dailyLimitUSD;
    uint256 perTxLimitUSD;
    uint8 maxPositionSizePct;
    uint16 maxSlippageBps;
    uint8 maxLeverage;
    bytes4[] allowedOperations;
    address[] allowedProtocols;
    uint256 dailySpentUSD;
    uint256 lastResetTimestamp;
}
