Settlement

​

Input settlement

• InputSettlerEscrow. Standard escrow that associates tokens with their intent.
• InputSettlerCompact. Long-lived deposits via The Compact resource lock.

​

StandardOrder

struct StandardOrder {
    address user;
    uint256 nonce;
    uint256 originChainId;
    uint32 expires;
    uint32 fillDeadline;
    address inputOracle;
    uint256[2][] inputs;
    MandateOutput[] outputs;
}

​

MandateOutput

struct MandateOutput {
    bytes32 oracle;
    bytes32 settler;
    uint256 chainId;
    bytes32 token;
    uint256 amount;
    bytes32 recipient;
    bytes call;
    bytes context;
}

​

Finalization

1. finalise Called by the solver. The caller designates where to send assets and whether to make an external call.
2. finaliseWithSignature Called by anyone with an AllowOpen signature from the solver containing destination and call details.

​

Compact Registration

struct BatchCompact {
    address arbiter;
    address sponsor;
    uint256 nonce;
    uint256 expires;
    uint256[2][] idsAndAmounts;
    Mandate mandate;
}

struct Mandate {
    uint32 fillDeadline;
    address inputOracle;
    MandateOutput[] outputs;
}

​

Escrow Registration

1. Direct open by the owner through ERC-7683 function open(bytes). Emits event Open(bytes32 indexed orderId, bytes order).
2. ERC-3009 with the orderId as nonce. A signature per input is required.
3. Permit2 with an EIP-712 signed PermitBatchWitnessTransferFrom.

​

Integration Examples

• Smart contract registration: RegisterIntentLib.sol
• UI signing (Batch Compact): lintent.org demo
• UI deposit and registration: lintent.org demo

Configuring Auction Type

// Simple limit order (no auction)
context = "0x" or "0x00";

// Dutch auction
context = abi.encodePacked(0x01, slope, stopTime);
