There’s this decentralized coin-coin marketplace in the works called “Haveno” which is basicially Bisq, but based on monero. I think this is something you ought to look into if you haven’t already. Could really be a boon for Firo usage and awareness.
Looks like someone has already requested a firo listing ([Crypto] Add Firo · Issue #49 · haveno-dex/listing · GitHub). I assume that because firo is based on bitcoin, that you’ll have an easier time setting up the HLTCs needed for doing atomic swaps?
