I think Firo is pretty legit, in fact the way I found out about it was from a monero blog post: https://www.getmonero.org/2021/12/22/what-is-seraphis.html

Currently the only way to buy it is over TradeOgre or Binance. I'd like to see it implemented on haveno. I think zcoin/firo is bitcoin-based so I'm pretty sure it inherits its scripting mechanisms: should be straightforward to implement atomic swaps.
