Fastest Robinhood Chain RPC with API key: Chainstack vs Alchemy vs QuickNode
eth_getBlockByNumber latency against keyed Robinhood Chain endpoints (Chainstack, Alchemy, QuickNode), probed every 60 seconds from US-East and US-West.
TL;DR. As of , Alchemy posts the lowest rpc latency at 6 ms (p50, 24h) on Fastest Robinhood Chain RPC with API key: Chainstack vs Alchemy vs QuickNode. Source: OpenChainBench, https://openchainbench.com/benchmarks/keyed-rpc-robinhood.
Robinhood Chain (chain ID 4663) is an Arbitrum Orbit L2 designed for tokenized equity trading, launched in March 2026 with a gas subsidy running through September 2026. It is the first chain where Chainstack launched a Global Node before Alchemy, giving it an early infrastructure advantage on 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) and US-West (Oregon). Robinhood Chain is built for US equity trading; US probe coverage is what matters for the applications that use it. Chainstack recorded p50 of 72ms in internal pre-launch tests vs Alchemy at 86ms; live data on this page reflects continuous measurement since the bench launched. This is the only independently-run public latency benchmark for Robinhood Chain.
Methodology
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 and US-West, and classifies each response as ok, http_err, jsonrpc_err, stale, or timeout. Only ok responses contribute to the latency distribution.
Frequently asked
Which Robinhood Chain RPC provider is fastest?
It depends on your probe region. From US-East (Virginia): Chainstack at 30 ms p50. From US-West (Oregon): Alchemy at 6 ms p50, because Chainstack does not currently respond from Oregon. For East Coast deployments, Chainstack wins. For West Coast, Alchemy is the pick.
What is Robinhood Chain?
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.
Why is Chainstack missing from US-West?
Chainstack's Robinhood Chain Global Node appears to be anchored in a US-East datacenter (Virginia). Probe calls from Oregon return no successful responses, so the US-West latency column shows no data for Chainstack. This is consistent with Chainstack's current infrastructure footprint for this chain.
Why is this the only Robinhood Chain latency benchmark?
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.
Why do you only probe from US regions?
Robinhood Chain is purpose-built for US equity trading. The applications and bots that depend on its RPC latency run in US infrastructure. Probing from EU or Asia would produce numbers irrelevant to the actual use case.
