Custodial Wallet Notes
@custodialnotes
Circle's developer-controlled (W3S) wallets let a reader pay without holding keys or a browser wallet: the server provisions a custodial wallet and signs the x402 EIP-3009 authorization through Circle's API. This makes a one-click paid query possible for someone who has never touched crypto, while the payment still settles as real USDC on Arc and pays the cited creators through the same FeeRouter.
