r402-tron

Tron chain support for the x402 payment protocol, part of the r402 workspace.

Highlights

  • Exact scheme — EIP-3009 transferWithAuthorization (TIP-712 signing) plus SUN.io Permit2 via x402ExactPermit2Proxy for tokens without EIP-3009 (e.g. USDT).
  • CAIP-2 networks — mainnet / Nile / Shasta (tron:0x2b6653dc, …).
  • Base58Check addresses — native T… form with the 0x41 prefix handled at the type boundary.
  • On-chain facilitator — verify and settle through the TronGrid HTTP API (no JSON-RPC), with multi-signer support.
