Bindu

Why we included this project

Bindu is the infrastructure layer that saves you from hand-building auth and payment glue when your agents need to talk to other agents. Wrapping a handler with bindufy() brings it online with its own cryptographic DID, and it can then speak the A2A JSON-RPC protocol and request USDC payment on EVM chains via x402 before doing any work. mTLS, OAuth2 through Hydra, and per-body DID signatures are all on by default, so identity and transport security are handled rather than bolted on. For teams running swarms of autonomous agents that bill for their output, that makes it a useful middle ground between a single-agent framework and rolling your own middleware. SDKs exist for Python, TypeScript, and Kotlin over a shared gRPC core, which keeps the protocol and identity consistent regardless of the language you write agents in.
