BTC-XMR atomic swaps are now live on their mainnets. I have been talking with some Monero developers about how BCH-XMR atomic swaps could be implemented. They say they do not think it is possible without SegWit.
Is this true? If it isn’t true, then it could be good to demonstrate that BCH can do XMR-BCH atomic swaps without SegWit. However, I am not in a position to implement an atomic swap capability nor even really understand the technical details of how it might be done. I can provide the Monero developer’s discussion contact upon request if there is interest in this.
