Fastest free dYdX Chain RPC, live no-key Cosmos SDK endpoint latency
HTTP round-trip latency for the Tendermint status method against every free, no-key public dYdX Chain Cosmos SDK endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Polkachu leads rpc latency at 186 ms (p50, 24h) on Fastest free dYdX Chain RPC, live no-key Cosmos SDK endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/dydx-rpc.

dYdX Chain (dydx-mainnet-1) is a Cosmos SDK app-chain running the dYdX perpetuals DEX entirely on-chain in CometBFT consensus, with ~1 s block time and the DYDX governance token. PublicNode, Polkachu, and LavenderFive all run keyless Tendermint RPC endpoints probed every 60 seconds from three regions.
Methodology
Per-chain member of the RPC latency cluster, extended to dYdX Chain. We measure the round-trip latency of a single, identical Cosmos SDK call (Tendermint `status`) against every no-key public dYdX Chain endpoint that sustains continuous probing, 3 providers at launch, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a dYdX-scaled staleness gap (40 blocks at ~1 s block time). The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the dYdX Chain-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free dYdX Chain RPC right now?
Polkachu currently leads at 186 ms (Tendermint `status` p50 over the last 24h), measured against 3 no-key providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples.
Which dYdX Chain RPCs work without an API key?
3 endpoints sustain continuous keyless probing at launch: PublicNode, Polkachu, LavenderFive. Every listed endpoint was live-verified before inclusion.
Does the fastest dYdX Chain RPC change by region?
Often. Public infra concentrates in specific regions; a node that wins from Virginia can lose from Singapore by multiples. The region tabs at the top of the page re-scope every number to a single origin.
How is dYdX Chain RPC latency measured here?
One identical Tendermint `status` POST every 60 seconds against each provider from each of 3 regions. Responses are classified (`ok` / `http_err` / `jsonrpc_err` / `stale` / `timeout`) so an endpoint stuck on an old block is never ranked as fastest.
