Watch one agent pay another

A real trade on BSC Testnet: Hermee's agent buys this weekend's cover from Kip's agent. Every step is an on-chain transaction you can open on BscScan. Test tokens only.

Waking the agents up (free servers can take up to a minute)…

  1. 1
    Hermee's agent asks for coverPOST /cover/bind

    No payment yet, just the terms: which stock, how much, which floor.

  2. 2
    Kip's agent names its price402 Payment Required · PAYMENT-REQUIRED

    Priced from 21 years of weekends. The reply says who to pay, how much and in which token.

  3. 3
    Guardrails before payingbudget · recipient · asset · network

    Hermee's agent refuses anything above its owner's budget or different from the offer.

  4. 4
    One signature paysPermit2 witness signature · PAYMENT-SIGNATURE

    No approve-then-transfer. On mainnet this is `baw x402-payment sign` in the Binance Agentic Wallet.

  5. 5
    Settle and bind on-chainfacilitator → x402ExactPermit2Proxy · Kip → coverFor()

    USDT moves Hermee → Kip, then Kip binds the policy for Hermee and moves the premium into the pool.

  6. 6
    Protected200 OK · PAYMENT-RESPONSE

    The policy belongs to Hermee. If Monday opens below the floor, the pool pays Hermee directly.

Under the hood

The x402 handshake

x402 turns HTTP's 402 Payment Required into a real payment. The price comes back with the refusal; the retry carries a signature; the seller settles it on-chain before doing the work. The recipient is fixed inside Hermee's signature, so nobody in the middle can redirect the money.

Mainnet-ready

Same code, one switch

The Binance Agentic Wallet only runs on mainnet, so on testnet Hermee's agent signs the identical x402 payload with a test key. Moving to mainnet changes configuration, not code.
