Monero is available on Bisq as one of the payment options, alongside Wise, Revolut, and other banks and payment methods.

However, it is _not_ natively integrated as it is in Haveno/Retoswap.

Although most of the liquidity on Bisq over the years has been on the XMR/BTC pair, their "DAO" did not vote for the integration of Monero...

Probably they didn't want to create competition for Bitcoin, because people would start trading, for example, XMR/Revolut or XMR/Wise instead of pairing it with BTC.

Anyway, whatever. I haven't used Bisq since 2019. It's no longer needed in my toolkit.
