An atomic swap is not instant by design. Each side has to publish a transaction and wait for the other chain to confirm it, so the time it takes is set mostly by the block spacing of the two chains involved rather than by anything either party does.

The final claim did not go through on the first attempt

The record stops at MakerPaymentSpendFailed. The taker's claim on the maker's coin was rejected; it can be retried for as long as that payment is unspent.

the transaction was rejected by network rules. transaction already in block chain

By this step both payments were on their chains and the price had been struck, so the trade counts toward the reference price. The claim can still be made for as long as the payment is unspent, and since the timelock has passed the payer can take it back as well, so whichever lands first settles it. Whether it was retried is a question for the chain rather than for this log.

The chain says the claim landed: the payment was spent with the preimage, in 065ed95c40f90520b6d05d4ed19b693f33b5ea0d6b25ae2393e454e0e79981c0. Checked 2026-10-26 18:30:21 UTC.

Both payments are on their chains and locked to the same secret hash 3af04db720581e966145031b1138154c43df70f5, and a preimage hashing to it was published on chain when one side claimed.

No flags are stored against this swap. Flags are written while a swap sits inside a live pricing window, so on an older swap their absence means it was never assessed rather than that it was assessed and found clean.
