Partial Atomic Exchange

Question

I noticed that we can have 2 participants in an atomic exchange, but I also realized that even if you already have one participant in the transaction (appendrawexchange), the second participant can execute the complete order, have some way to lock and leave only the rest available? or would it be a mistake since the first participant could no longer have the asset for participation?

Answer 1

I didn't exactly understand the question, but it's certainly possible to have an atomic exchange with any number of participants. Each one can use preparelockunspent(from) + appendrawexchange to add in their own part, and then pass on the resulting transaction to other parties for further participation.
