How Payment Signing Works
Hunazo uses the x402 protocol for USDC payments on Base. This skill never handles private keys directly.
- Agent calls
POST /orders/{listing_id}?buyer_wallet=0x... - Server returns HTTP 402 with payment requirements (recipient, amount, escrow contract)
- Your local x402 client reads
WALLET_PRIVATE_KEYfrom the environment and signs a USDC transfer — signing happens entirely client-side - Agent re-submits with
X-PAYMENTheader containing the signed transaction - Server verifies on-chain payment and creates the order
The WALLET_PRIVATE_KEY env var is read only by your local x402 client library (x402-js or x402-python). The key never leaves your machine. Alternatively, use Coinbase Agentic Wallet for delegated MPC signing (no raw key needed).
