GitHub·medium signal

Bindu wraps any AI agent handler with bindufy() to generate a signed, secure microservice with A2A JSON-RPC communication on port 3773, decentralized identity (DIDs with Ed25519 signing), and x402 payment integration for USDC transactions on Base blockchain. The platform provides Python, TypeScript, and Kotlin SDKs built on a gRPC core, compatible with AG2, Agno, CrewAI, and LangChain frameworks. At 4.9K stars with 1,325 commits, Bindu is one of the first platforms to combine agent interoperability (A2A) with native crypto payments (x402) in a single deployment wrapper.
