Paycrow

io.github.michu5696/paycrow

This server lets Claude interact with escrow smart contracts on Base for agent-to-agent or human-to-agent payments. USDC gets locked in a contract until work is verified as complete, solving the trust problem when AI agents need to pay each other or receive payment for tasks. You'd reach for this when building autonomous agent workflows that involve money changing hands, like hiring an AI service to process data or commissioning work where you want funds held until delivery. The server exposes operations to create escrow agreements, release funds on completion, and query contract status. It runs on Base L2 to keep gas costs low for microtransactions.
