Peer (formerly ZKP2P) is a decentralized, zero-trust P2P legal currency-encrypted deposit and withdrawal protocol that uses zero-knowledge proof (ZK) and TEE technology to allow users to quickly buy and sell encrypted assets on Base, Solana and other chains without intermediaries through daily payment methods such as Venmo, CashApp, PayPal, Revolut, and Wise. It also supports functions such as liquidity provision, Vaults, and rankings.
