Circle's public chain Arc has officially announced that it has launched proxy payments.

Its Facilitator Service provides a hosted access path for x402 developers, allowing the acceptance of USDC and supporting on-chain settlements on Arc, Base, and Polygon; this path does not require a Relayer key or a separate Gas fee wallet.
