About
Niche is a CLI skill for a peer-to-peer trading card marketplace on Base Sepolia, enabling users to list, browse, and purchase cards using a secure, partial USDC deposit system. Its key feature is an on-chain escrow that allows buyers to deposit funds, inspect the card in person, and then complete the transaction. The skill uses a thin client architecture, offloading core logic like auth and signing to a hosted Supabase backend, and includes automated background tasks for checking card matches.
