Bisq is a decentralized, peer-to-peer exchange for buying and selling bitcoin with national currencies or other cryptocurrencies. No account creation, no KYC, no central server — trades are coordinated over Tor and settled via 2-of-2 multisig escrow with a third-party mediator.
HodlHodl is a non-custodial, peer-to-peer bitcoin exchange platform. Unlike Bisq, it is web-hosted rather than fully decentralized, but it remains non-custodial through 2-of-3 multisig escrow.

RoboSats is a peer-to-peer exchange for buying and selling bitcoin using Lightning Network payments. It operates entirely over Tor and uses temporary robot identities, meaning users do not accumulate persistent trade history or reputation.
