# Peer - Move Money Peer to Peer > Peer is a privacy-preserving, non-custodial peer-to-peer fiat<>crypto marketplace and payment protocol. Users move between fiat and crypto through buyer-generated cryptographic payment proofs, onchain escrow, and direct peer liquidity instead of a centralized exchange or custodial middleman. Peer was previously known as ZKP2P and is built on Base. Primary URL: https://peer.xyz App: https://app.peer.xyz Docs: https://docs.peer.xyz ## What Peer is Peer is a peer-to-peer crypto onramp and offramp. You can buy crypto using payment apps like Venmo, PayPal, Revolut, and Cash App, or sell crypto back to fiat. It is non-custodial, uses direct peer liquidity, and avoids custodial middlemen. Buyers generate cryptographic proofs that verify fiat payments while limiting exposed payment details. ## How Peer works 1. SEND - Connect via wallet, email, or socials, choose an offer, and send payment through a payment app you already use (Venmo, PayPal, Revolut, Cash App, etc.). 2. VERIFY - The buyer generates a cryptographic proof of the payment details needed for settlement without exposing their full account history. 3. RECEIVE - Once verified, crypto is released directly to your wallet. Timing depends on the payment rail and order flow. ## Why Peer - FAST: Use direct payment rails and live order state instead of waiting on custodial provider approvals. - FAIR: No custodial middleman and no hidden spread. Every transaction is direct, transparent, and priced by the market. - SIMPLE: Pick an amount, pay the way you normally do, and you are done. No confusing steps. - SECURE: Built on buyer-generated cryptographic payment proofs, not promises. Peer is non-custodial. ## Supported payment methods Venmo, PayPal, Revolut, Cash App, Zelle, Wise, Monzo, N26, Chime, Mercado Pago, Alipay, and Luxon. More payment methods are added regularly.

If you bridge to another chain, up to a 0.5% bridge fee also applies. - Order sizes: determined by each seller's configured range, current liquidity, and route validation. Taker tiers do not set caps. - Settlement time: varies by payment rail, proof verification, onchain release, and any bridge route. ## Privacy and verification Buyer-generated cryptographic payment proofs confirm that the payment happened while limiting exposed payment details. Peer uses wallet connection and payment verification instead of a separate custodial offramp account flow. ## Who Peer is built for - Privacy advocates: powered by buyer-generated cryptographic payment proofs, with minimized payment data exposure. - Newcomers: get crypto simply and safely, without confusing steps. - Liquidity providers: transparent demand and fair, market-driven returns. - Traders: move value fast and stay ahead without extra verification. - Businesses: Peer Pay (https://pay.peer.xyz) is checkout software on the Peer protocol for merchants that mainstream processors overlook. Customers pay in everyday apps, a buyer-generated cryptographic proof verifies each payment, and USDC settles to a wallet the merchant controls, with no processor balance, rolling reserve, or payout schedule. ## Frequently asked questions Canonical FAQ page: https://peer.xyz/faq Q: What is Peer?
