Verify and settle. Gasless.

The x402 facilitator for Robinhood Chain and Arc. Signed authorizations — USDG or USDC — are verified onchain and settled by our relayer. Funds move payer to merchant; we never hold them.

HOW IT PRINTS 3 steps

Verify

EIP-712 signature, nonce, window, balance

Settle

relayer submits transferWithAuthorization

Done

USDG lands at payTo, no custody

NON-CUSTODIAL · GASLESS FOR PAYERS

Status

Two rails, one endpoint.

A payment names the chain it belongs to; this facilitator answers on that one.

Mechanics

Three steps, one transaction.

Verify

Signature recovered against the token's EIP-712 domain. Nonce, time window, and balance checked onchain.

Settle

The relayer submits transferWithAuthorization and pays the gas — ether on Robinhood Chain, USDC on Arc. Payers never hold either.

Done

The stablecoin lands at the merchant's payTo address. One transaction, no custody.
