Txs like 4c7628f7a5c50c23f1c1d6038d72d9624e1ff9e7f9d3613aa64772c19721e82f (on testnet) should be shown as fulfillment btc txs

Can you remind me the technique you mentioned for locating these ?

one idea..

read stacks burn event,
read the withdraw request txid
get the fulfil address (2nd output)
read transactions to that address and find the one with
- correct opcode in op_return
- matching amount

record the txid and display as fulflment ?

It is probably enough to search for a FulfillBroadcasted event with the bitcoin request tx in it and then use the bitcoin txid of the fulfillBroadcasted event.

radicleart commented 10 months ago

question is where to search for this event? The bridge has no access to romeo events?

The signer has an rpc api. Maybe we will continue from there.
