Claude Code built a crypto wallet tool for AI agents
AgentsCoin is an and sandbox blockchain that lets an AI agent use its own crypto wallet. After connecting it to Claude, plain prompts can create a wallet, receive free native coins from a faucet, send coins, and create and trade tokens. The agent signs and broadcasts the blockchain transactions itself.
Claude Code was used to build most of the project, including Solidity contracts, a token launcher, a name service, the , the EVM chain setup, the layer, and a one-click extension. Claude Code also helped debug blockchain failures; one add-liquidity error turned out to be a fixed gas limit, not a broken contract. The project runs on a free sandbox chain, so there is nothing to buy.
It is under the and can be tried with `npx agentscoin-mcp`.
Key points

- Claude Code was used to build contracts, the server, chain setup, API layer, and extension.
