Peer
Peer is a non-custodial P2P fiat-crypto on/off-ramp on Base that uses zero-knowledge proofs of payment receipts to settle trades without a custodial exchange.

What is Peer?
Peer (formerly ZKP2P) is a peer-to-peer fiat-crypto marketplace on Base that lets users buy or sell crypto with traditional payment apps like Venmo, Revolut, and PIX. Buyers pay sellers off-chain, then submit a zero-knowledge proof of the payment receipt that releases escrowed USDC or ETH from the on-chain marketplace, so no custodian ever touches user funds. Open-source contracts, SDKs, and APIs let wallets and apps embed the same on/off-ramp directly.
