+  Robinhood Chain endpoints every 60 seconds from us-east, eu-west, and
+  Singapore. Chainstack recorded p50 of 72ms in internal pre-launch tests

   data on this page reflects continuous measurement since the bench
   launched; Robinhood Chain data accumulates over the first 24 hours.
   This is the only independently-run public latency benchmark for
   Robinhood Chain.
 
 abstract: |
   We measure the round-trip latency of eth_getBlockByNumber against the
-  keyed endpoints of Chainstack and Alchemy on Robinhood Chain. The probe
-  uses a rotating JSON-RPC id to defeat edge caches, fires every 60
-  seconds from 3 regions, and classifies each response as ok, http_err,
+  keyed endpoints of Chainstack, Alchemy, and QuickNode on Robinhood Chain.
+  The probe uses a rotating JSON-RPC id to defeat edge caches, fires every
+  60 seconds from 3 regions, and classifies each response as ok, http_err,
   jsonrpc_err, stale, or timeout. Only ok responses contribute to the
   latency distribution. This is a new bench; the first 24h of live data
   will replace the pre-launch internal test numbers in the findings.
 
 methodology:
   - "Cadence: every 60 seconds per provider from each of 3 probe regions (us-east, eu-west, sgp). 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 with the Robinhood Chain endpoint. Both are from paid accounts; the serving infrastructure matches the free-tier Global Node product."
+  - "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 and Alchemy. QuickNode supports Robinhood Chain per their documentation but a keyed endpoint is pending provisioning. Infura and Ankr do not currently list Robinhood Chain in their supported networks."

 findings:
-  - "{{name:chainstack}} leads at {{p50:chainstack}} (p50, 24h). In pre-launch internal tests (50 samples, single region), it recorded 72ms vs Alchemy at 86ms and the official public RPC at 170ms."

 faq:
   - q: "Which Robinhood Chain RPC provider is fastest?"
-    a: "Per the live data above: {{name:chainstack}} at {{p50:chainstack}} (p50 over 24h). In internal pre-launch tests Chainstack recorded 72ms vs Alchemy at 86ms. If you already use Alchemy for Ethereum or Arbitrum, adding Robinhood Chain requires no new account."

QuickNode also supports Robinhood Chain via its shared-endpoint fleet. If you already use Alchemy for Ethereum or Arbitrum, adding Robinhood Chain requires no new account."
   - q: "What is Robinhood Chain?"
     a: "Robinhood Chain (chain ID 4663) is an Arbitrum Orbit L2 built by Robinhood for tokenized equity trading. It launched in March 2026 with ~100ms block times and a gas fee subsidy running through September 29, 2026. It supports EVM-compatible tooling and standard eth_ JSON-RPC methods."
   - q: "Why is this the only Robinhood Chain latency benchmark?"
-    a: "Robinhood Chain is a new chain with limited third-party RPC support at launch. OpenChainBench added it within days of Chainstack and Alchemy support going live, making this the first and so far only independent latency measurement. Additional providers will be added as they launch keyed endpoints."
