Robinhood Chain RPC endpoints: free public URLs and private API-key providers by latency
HTTP round-trip latency for eth_getBlockByNumber against every free, no-key public Robinhood Chain RPC endpoint (probed every 60 seconds from 3 regions) and, under the Access selector (Private), against the API-key endpoints of Chainstack, Alchemy, QuickNode and GetBlock (every 120 seconds from us-east and eu-west). The two cohorts are ranked separately, never against each other.
TL;DR. As of , dRPC has the lowest median latency of the 4 free public Robinhood Chain RPC endpoints measured, 35 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/robinhood-rpc. Chain ID 4663. 4 public endpoints, no key: robinhood.drpc.org, robinhood-rpc.publicnode.com, robinhood.rpc.blxrbdn.com, rpc.mainnet.chain.robinhood.com. Full URLs with their 24h median are listed below; Chainstack, Alchemy, QuickNode, GetBlock, Dwellir (private, API key) are ranked apart under the Private tab.

Robinhood Chain (chain ID 4663) is Robinhood's Arbitrum Orbit L2 for tokenized equity trading, live on mainnet since July 2026 with about 100 ms blocks. Its RPC field is young: a rate-limited official endpoint, three public gateways (dRPC, PublicNode, bloXroute) and keyed endpoints at Chainstack, Alchemy, QuickNode and GetBlock. This page measures both sides with one probe, `eth_getBlockByNumber` with a rotating request id, every 60 seconds on the 4 free endpoints from us-east, eu-west and Singapore, and every 120 seconds on the keyed ones from us-east and eu-west: GetBlock does not offer Robinhood Chain in Singapore, and averaging a two-region row against three-region rows would compare different populations, so the keyed cohort is measured from the two regions the chain is served from. The Access selector switches between the two cohorts, which are never ranked against each other.
Methodology
Robinhood Chain: 4 free public RPC endpoints answering `eth_getBlockByNumber` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. dRPC leads at 35 ms; the Robinhood-operated endpoint measures 131 ms. The same page carries the private cohort (API key), Chainstack, Alchemy, QuickNode and GetBlock on their keyed Robinhood Chain endpoints every 120 seconds from us-east and eu-west: switch the Access selector; Chainstack leads it at 6 ms. We measure the round-trip latency of a single, identical RPC call (`eth_getBlockByNumber`) against every no-key public Robinhood Chain endpoint that sustains continuous probing, 4 providers, every 60 seconds, from us-east, eu-west and Singapore, and against the keyed endpoints of Chainstack, Alchemy, QuickNode and GetBlock every 120 seconds from us-east and eu-west, the two regions the chain is served from. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) so the leaderboard rewards sustained, honest availability rather than a fast error message. Robinhood Chain runs on the Arbitrum Orbit stack with about 100 ms block times; the probe samples the serving path, not block production.

Frequently asked
Which Robinhood Chain RPCs work without an API key?
4 endpoints are probed on this chain; each is listed with its URL, 24h median and success rate in the endpoints table on this page, and the list changes as providers come and go. Every (provider, chain) pair was live-verified no-key before inclusion; anything that key-gates, region-blocks or rate-limits below the 60-second cadence is excluded rather than listed with an asterisk.
Which Robinhood Chain RPC provider is fastest with an API key?
Per the live data: Chainstack at 6 ms (eth_getBlockByNumber p50 over 24h, averaged across us-east and eu-west); Alchemy measures 12 ms, Chainstack 6 ms and QuickNode 7 ms; GetBlock measures 10 ms. The keyed cohort is measured from those two regions only, because GetBlock does not offer Robinhood Chain in Singapore and averaging a two-region row against three-region rows would compare different populations; no keyed row exists for the Singapore tab, which is a coverage fact rather than a failed measurement. On the free cohort dRPC leads at 35 ms, measured on the same call from 3 regions; the two cohorts are never ranked in one table (shared gateways at 60 s against metered endpoints at 120 s). Switch the Access selector to Private for the region tabs and the p99 column; plan tiers are disclosed in the methodology.
What is Robinhood Chain?
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 about 100 ms block times and a gas fee subsidy running through September 29, 2026. It supports EVM tooling and standard eth_ JSON-RPC methods; the official endpoint rpc.mainnet.chain.robinhood.com is free, rate-limited and documented as suited to wallet connectivity and testing.
