subsidy running through September 2026. It is a financially-sensitive
chain with low tolerance for RPC latency.
This bench probes Chainstack, Alchemy, and QuickNode on their keyed
Robinhood Chain endpoints every 60 seconds from US-East (Virginia).
Chainstack leads from US-East. This is the only independently-run public
Robinhood Chain endpoints every 60 seconds from Singapore, the closest probe region to the
chain’s Asia-Pacific infrastructure. Chainstack leads. 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, Alchemy, and QuickNode on Robinhood Chain.
The probe uses a rotating JSON-RPC id to defeat edge caches, fires every
60 seconds from US-East (Virginia), and classifies each response as ok,
60 seconds, and classifies each response as ok,
http_err, jsonrpc_err, stale, or timeout. Only ok responses contribute to
the latency distribution.

methodology:
- "Cadence: every 60 seconds per provider from US-East (Virginia). Robinhood Chain runs on the Arbitrum Orbit stack with ~100ms block times; the 60s probe cadence captures 600 blocks per hour."
- "Cadence: every 60 seconds per provider from Singapore. Robinhood Chain runs on the Arbitrum Orbit stack with ~100ms block times; the 60s probe cadence captures 600 blocks per hour."
- "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."

findings:
- "{{name:chainstack}} leads at {{p50:chainstack}} (p50, 24h) from US-East. Its Global Node, launched first on Robinhood Chain, delivers the lowest round-trip latency in this benchmark."
- "{{name:alchemy}} records {{p50:alchemy}} from US-East via its edge infrastructure."
- "{{name:chainstack}} leads at {{p50:chainstack}} (p50, 24h). Its Global Node, launched first on Robinhood Chain, delivers the lowest round-trip latency in this benchmark."
- "{{name:alchemy}} records {{p50:alchemy}} via its edge infrastructure."
- "{{name:quicknode}} delivers {{p50:quicknode}} via its shared-endpoint fleet."

faq:
- q: "Which Robinhood Chain RPC provider is fastest?"
a: "Per the live data above: {{name:chainstack}} at {{p50:chainstack}} p50 (24h, from US-East). It is the lowest-latency keyed provider for Robinhood Chain in this benchmark."
a: "Per the live data above: {{name:chainstack}} at {{p50:chainstack}} p50 (24h). It is the lowest-latency keyed provider for Robinhood Chain in this benchmark."
- 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 on mainnet in July 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. OpenChainBench added it within days of Chainstack, Alchemy, and QuickNode support going live, making this the first and so far only independent latency measurement. Infura and Ankr do not currently list Robinhood Chain in their supported networks."
- q: "Why only US-East?"
a: "The probe runs from US-East (Virginia) where the Railway infrastructure is located. Additional probe regions may be added as the chain matures and more regional endpoints become available."
- q: "Where does this benchmark probe from?"
a: "The probe runs from Singapore, the region closest to the chain’s Asia-Pacific infrastructure, where all three providers serve their lowest-latency responses. Additional probe regions may be added as the chain matures."
