Bankr Sign & Submit API
Streamlines blockchain transaction signing and submission using Bankr's synchronous multi-chain API endpoints.
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.
