The payment proof that releases your USDC runs in a desktop Chrome extension. It can't complete inside a phone browser. Open 4sight.money on desktop Chrome to finish. Quotes appear above when matching USD liquidity is available; selling stables and viewing rates work here on mobile.

Payment proof runs in the PeerAuth extension (desktop Chrome). Your wallet signs the onchain settlement. 4SIGHT never holds your keys.

Funds sit in Peer escrow on Base, linked to your wallet. Fiat moves directly between bank apps; zk payment proofs release escrow. 4SIGHT never custodies your money.

How P2P settlement works

01 · ESCROWYou lock stablecoins

Deposit USDC into Peer escrow on Base and set your platform, currency, and rate.

02 · INTENTA buyer takes your offer

The buyer commits onchain to your deposit. Your escrow is reserved at your quoted rate.

03 · PAYThey pay you in fiat

The buyer sends fiat to your Wise, Revolut or Venmo at exactly the quoted rate. Your USDC stays escrowed until proof.

04 · PROVEProof releases escrow

A zkTLS proof verifies the bank transfer, and escrow releases the USDC to the buyer. You keep the fiat. Timing depends on payment and proof completion.
