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.
TL;DR. As of , Chainstack posts the lowest rpc latency at 3 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 on mainnet in July 2026 with a gas 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 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.
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 Singapore, the closest probe region to the chain's Asia-Pacific infrastructure, 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?
Per the live data above: Chainstack at 3 ms p50 (24h). It is the lowest-latency keyed provider for Robinhood Chain in this benchmark.
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 ~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 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.
Where does this benchmark probe from?
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.
