 * so no shared public infrastructure sits on the payment-signing path and no
 * extra configuration is required to use them.
 *
 * All other networks (Polygon, Arbitrum, World, etc.) have no default RPC.
 * RPC URLs are optional for core payload signing on those networks — they're
 * only needed to backfill optional extension capabilities (for example,
 * `eip2612` gas-sponsoring enrichment) — so callers that need one must supply
 * it explicitly via the `rpcUrls` config option or `CDP_X402_RPC_URLS`
 * environment variable.

 * that resolved successfully.
