0verice

0verice is a peer-to-peer foreign cash exchange protocol on Monad. A Next.js frontend connected to a Solidity escrow contract (Foundry). Tourists swap leftover cash for USDC via local agents. The contract holds USDC in escrow, releases on agent-signed QR confirmation. Agent earns 5% margin (capped 1 USDC). Deployed on Monad Testnet. Local Agent is human not an AI. Travelers are stuck with foreign cash after trips banks and airport kiosks charge 5–10%. There's no peer-to-peer market for cash-for-USDC exchange. 0verice removes the intermediary: tourist meets agent, cash changes hands, USDC settles on-chain instantly near mid-market rate. I learn about escrow, how to build assisted with AI, and some frontend integration with contract.
