Events and errors

AI-generated

Index events by chain ID and deployment, in canonical block, transaction, and log order. Successful receipts and matching events establish completed actions; getSwap alone cannot distinguish terminal outcomes.

Events

event IntentCreated(
    bytes32 indexed swapId,
    address indexed user,
    bytes recipientAddress,
    uint256 ethPrincipal,
    uint64 minXmrAmount,
    uint64 minPaymentHeight,
    uint128 randomxDifficulty,
    uint256 auctionEndTimestamp,
    uint256 deadlineTimestamp
);
event BestBidChanged(bytes32 indexed swapId, address indexed bestSolver, uint64 bidXmrAmount);
event SwapSettled(bytes32 indexed swapId, bytes32 indexed txid);
event SwapExpired(bytes32 indexed swapId);

BestBidChanged does not include the previous bidder, bond, or refund outcome. SwapSettled does not include the selected output key or recipient; those require the stored creation history and settlement calldata. SwapExpired does not encode whether a winner existed; derive the payout from the prior history.

Every terminal transfer is exact-or-revert. A log from a reverted execution is not a committed event.

Custom errors

Signature	Meaning
`Reentrancy()`	A guarded action was reentered.
`InvalidVerifier()`	Constructor verifier address has no code.
`InvalidProgramVKey()`	Constructor program key is zero.
`InvalidDeploymentParameters()`	Invalid positive bounds or minimum greater than maximum.
`InvalidRecipientLength()`	Recipient length is not exactly 95 bytes.
`ZeroPrincipal()`	Creation supplied no ETH principal.
`ZeroIntentField()`	Minimum XMR, minimum height, or difficulty is zero.
`InvalidSettlementWindow()`	Requested window is outside the immutable inclusive bounds.
`SwapNotFound()`	There is no live row for the ID, including after either terminal action.
`AuctionClosed()`	Bid timestamp is at or beyond auction end.
`AuctionNotEnded()`	Action requires auction close but it has not occurred.
`BidTooLow()`	Bid does not strictly exceed stored best XMR.
`IncorrectBond(uint256 expected, uint256 actual)`	Bid ETH value differs from the exact calculated bond.
`InsufficientGasForRefund(uint256 available, uint256 required)`	Replacement bid lacks the pre-refund gas reserve.
`NoWinningSolver()`	Settlement attempted without a winner.
`SettlementDeadlineReached()`	Settlement timestamp is at or beyond the deadline.
`SettlementDeadlineNotReached()`	Winning-bid expiry attempted before the deadline.
`TransactionAlreadyUsed()`	Transaction ID was consumed by a previous successful settlement.
`OutputAlreadyUsed()`	Recipient/output nullifier was previously consumed.
`ProofVerificationFailed()`	Proof selector/length check or verifier call failed.
`EthTransferFailed(address recipient, uint256 amount)`	Final payout failed; the whole settlement or expiry reverted.

These are all 21 custom errors. ABI decoding, arithmetic panics, out-of-gas execution, and infrastructure failures can also prevent success. Indexers must handle reorganizations.
