What HEY checked — why it says this
Active.
“Active” by the activity rule's longer window: 2 meaningful events in the last 45 days (the rule needs at least 2); the newest, 2026-09-08, is more than 30 days old.

    Initial release. Verify-only x402 facilitator for Robinhood Chain (eip155:4663), settling in USDG. 🟢 Live: https://x402-facilitator-evm.purplesquirrelnetworks.workers.dev The hosted x402.org facilitator serves only Base Sepolia; this one serves Robinhood Chain. USDG (the chain has no canonical USDC) implements EIP-3009, established by probing revert selectors since USDG is an EIP-2535 Diamond. Scope: /verify only. No /settle — that needs a funded hot signer and is deliberately out of scope; the service holds no keys and CI enforces that invariant.…
