Trustramp

Trustless escrow for P2P crypto-to-fiat remittance trades, built for UK↔Nigeria transfers. P2P trades between strangers run on blind trust: no rate transparency, and no protection if the other side doesn't pay. Trustramp fixes the trust problem specifically — the sender locks stablecoin in an onchain escrow contract, the receiver confirms once the fiat leg lands, and only then does the sender release funds. If the receiver never confirms, the sender can reclaim everything automatically once the window closes. Every trade also updates each wallet's onchain reputation, so before you trade with a stranger you can check their history of clean trades, refunds, and disputes. Built on Monad testnet: Solidity escrow contract (OpenZeppelin primitives, 13 tests covering the full lifecycle — confirm/release, refund-on-timeout, dispute resolution both directions, and access control), verified onchain, with a Next.js/wagmi frontend. Also includes a live USD→NGN rate-check widget so senders can catch a lowballed P2P offer before they even open a trade. Scope, honestly: no KYC, no bank rails — this solves the "will I get paid" trust problem, not FX conversion itself. Dispute resolution is a single trusted arbiter for this MVP; a production version would need a multisig.
