This skill provides specialized guidance and TypeScript implementation patterns for interacting with Bankr's synchronous signing and submission infrastructure. It enables developers to handle cryptographic signatures—including personal messages, EIP-712 typed data, and raw transactions—and broadcast them to multiple EVM-compatible chains like Base, Ethereum, and Polygon without the complexity of job polling. By providing structured data patterns for the /agent/sign and /agent/submit endpoints, this skill simplifies the creation of secure DeFi applications, automated trading workflows, and Web3 authentication systems within Claude Code.
