1.0.0 is a ground-up rewrite to a TypeScript-only pnpm/turbo monorepo. The previous Python + TypeScript SDK moved to legacy/ for reference.

Supported schemes: exact, upto, batch-settlement, auth-capture (EVM), and exact_gasfree (TRON).

📦 Published Packages

@bankofai/x402-core, x402-evm, x402-tron, x402-fetch, x402-express, x402-mcp, x402-extensions — all at 1.0.0.

npm install @bankofai/x402-fetch @bankofai/x402-evm @bankofai/x402-tron

✨ Highlights

  • Network-driven signer factories keyed by CAIP-2 IDs, with @bankofai/agent-wallet integration.
  • New schemes: upto, batch-settlement, auth-capture.
  • BSC support — testnet + mainnet (eip155:56) USDT.
  • MCP transport for the Agentic Web.
  • Injectable global Logger with structured verify/settle logging.

🐛 Key Fixes

  • TRON settle receipt polling switched to gettransactioninfobyid — no more false REVERT on mainnet.
  • Hardened TRON settle confirmation with packed-speed polling.
  • GasFree returns [] on 404 (network unsupported).

✅ Verification

  • BSC testnet USDT exact settle: 0x477f00…a9edd (SUCCESS).
  • TRON mainnet USDT exact: 604f51c8…0acc (contractRet: SUCCESS).

Compatibility: Node.js ≥ 20, pnpm ≥ 11.
