The only one I have used is peach bitcoin, it's a kyc free peer 2 peer exchange, relai is another kyc free exchange, but not peer 2 peer, but both of these are only kyc free under a certain threshold. They are both based in Switzerland hence the kyc loophole.
Discussion
Are they on-chain based or lightning based?
They are both on chain as far as I know. Robosats is the lightning kyc free one right? Not tried that one out yet, but it looks good.
Oh yeah, these guys are only really available in Europe too I believe.
Robosats is lightning for sure! But supports on chain as well.
Btw, how is the liquidity on peach btc?
I've only ever bought on peach (never sold a sat... zapped a few though lol) but when I bought there were plenty of offers and enough competition that the % over market was pretty low.
