ABI reference

The selectors and event topic0 values on this page are the V6 ABI for IntentSettlerV3 and IntentLensV3.

(O) below abbreviates the complete IntentOrder tuple:

(address owner,address recipient,address tokenIn,uint256 amountIn,
 address tokenOut,uint256 startAmountOut,uint256 endAmountOut,
 uint256 startTime,uint256 decayEndTime,uint256 endTime,
 bytes32 appData,uint256 nonce)

Events and topic0

Event signature	topic0
IntentAnnounced(bytes32,address,bytes32,bytes,bytes)	0x6b7c7ccca26b7cb9642ad63c79054835d7bbfb9801b6c6c642a3ba88ece2350f
IntentFilled(bytes32,address,address,address,address,uint256,uint256,uint256,uint256,uint256)	0x9e24c3cf62be0eab4747b63a88ac76a698ffb40e8c7821be18e4f07cd72ccbd5

Indexed and data fields

Event	Indexed topics	Data fields
IntentAnnounced	id, owner, appData	bytes order, bytes auth
IntentFilled	id, owner, solver	recipient, caller, amountIn, requiredOut, fee, receivedOut, aboveFloor
IntentCancelled	id, owner, caller	none

IntentAnnounced.order is abi.encode(IntentOrder). It is complete and self-describing; individual order fields are intentionally not duplicated in the event. In V6, auth is the authorization envelope, requiredOut is gross (floor plus fee), fee is the protocol fee paid by the filler on top, and aboveFloor is the amount received above gross requiredOut and sent to the signed recipient.
