x402-demo: Base mainnet + CDP facilitator (durability) - #218
Merged
Conversation
Env-driven network (X402_NETWORK=eip155:8453 → Base mainnet) with the authenticated Coinbase CDP facilitator for verify/settle (the public x402.org facilitator is Sepolia-only). Default stays Base Sepolia. Drops railway.json watchPatterns, which never matched under the --path-as-root manual upload and silently SKIPPED deploys. This is the state already running in prod on x402.codespar.dev (deployed via manual railway up); this commit makes it durable in main. Only the four demo files change — no catalog packages touched.

What
Makes the mainnet x402-demo durable in main.
x402.codespar.devhas been selling on Base mainnet since 07-09 (deployed via manualrailway up), but the code only lived on an old divergent branch + the running container. This lands exactly that state, cleanly.server.ts— env-driven network:X402_NETWORK=eip155:8453→ Base mainnet via the authenticated CDP facilitator (the public x402.org facilitator is Sepolia-only). Default stays Sepolia.package.json/package-lock.json— adds@coinbase/x402(the CDP facilitator client).railway.json— dropswatchPatterns, which never matched under--path-as-rootmanual upload and silently SKIPPED deploys.Why a fresh branch
The original work sat on
feat/x402-cdp-connection, branched from an old main — diffing it now showed ~40 catalog packages as deletions (branch was behind). This PR is a fresh branch off currentorigin/maincarrying only the 4 demo files — no catalog packages touched.🤖 Generated with Claude Code
