Robinhood Chain runs on the Arbitrum Orbit stack with ~100ms block times; the 60s probe cadence captures 600 blocks per hour. Headline p50/p90/p99 aggregate across regions via Prometheus avg(quantile_over_time(...)).","Payload: eth_getBlockByNumber('latest', false) with a rotating JSON-RPC id. Non-cacheable by design: the rotating id defeats body-keyed edge caches and forces the provider to serve a real Robinhood Chain tip.","Authentication: Chainstack Global Node key (node-scoped, dedicated to Robinhood Chain; key in Railway env, not in repo). Alchemy uses its standard multi-chain key. QuickNode uses its shared-endpoint key for Robinhood Chain. All keys in Railway env, not in repo.","Call-result classification: ok (HTTP 200 with usable block number), http_err, jsonrpc_err (HTTP 200 with error body), stale (block more than 20 behind the cross-provider tip), timeout. Latency is recorded only for ok responses.","Cohort: Chainstack, Alchemy, and QuickNode. Infura and Ankr do not currently list Robinhood Chain in their supported networks. Probe regions are US-only because Robinhood Chain serves a US equity trading audience."],"license":"CC-BY-4.0"}
