Settlement Model

On Arbitrum, the facilitator validates the EIP-3009 transferWithAuthorization against the payment requirements — same as Base. Recipient, token, amount, and timing are all checked before settlement.

What Integrators Should Validate

  1. The route uses the correct Arbitrum network identifier (eip155:42161)
  2. The payment asset and recipient match the expected requirements
  3. The facilitator accepts the payload and settles successfully
