Bankr X402 SDK Transaction Builder

If you're building blockchain interactions into Claude workflows, this handles the transaction construction part across common operations like ERC20 transfers, NFT purchases, wrapping ETH, and cross-chain bridges. It supports the major use cases you'd expect: sending tokens, minting NFTs from Manifold or SeaDrop contracts, and bridging between chains. The prompt interface is straightforward, you just tell it what you want in plain language and it builds the transaction object. Useful if you're prototyping DeFi tools or building agents that need to interact with Ethereum and L2s without writing transaction logic from scratch every time. The repo has 78 stars, so there's at least some community validation here.
