Fastest free Astar Network RPC, live no-key endpoint latency
HTTP round-trip latency for eth_getBlockByNumber against every free, no-key public Astar Network RPC endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , OnFinality leads rpc latency at 52 ms (p50, 24h) on Fastest free Astar Network RPC, live no-key endpoint latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/astar-rpc.

Astar Network (chain 592) is Polkadot's flagship EVM and WebAssembly parachain, ASTR gas token, supporting both Solidity and ink! smart contracts. Developed by Startale (formerly Stake Technologies) and chosen by Sony for Soneium infrastructure, it exposes a standard EVM endpoint alongside Substrate RPC. The Foundation's evm.astar.network, BlastAPI, and OnFinality provide keyless access probed every 60 seconds from three regions.
Methodology
Per-chain member of the RPC latency cluster, extended to Astar Network. We measure the round-trip latency of a single, identical RPC call (`eth_getBlockByNumber`) against every no-key public Astar Network endpoint that sustains continuous probing, 4 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) so the leaderboard rewards sustained availability rather than fast error messages. The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Astar Network-scoped answer with per-region breakdowns as a first-class dimension.
Frequently asked
What is the fastest free Astar Network RPC right now?
OnFinality currently leads at 52 ms (`eth_getBlockByNumber` p50 over the last 24h), measured against 4 no-key providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples.
Which Astar Network RPCs work without an API key?
4 endpoints sustain continuous keyless probing at launch: Astar Foundation, BlastAPI, OnFinality, 1RPC. Every listed endpoint was live-verified before inclusion.
Does the fastest Astar Network RPC change by region?
Often. The region tabs at the top of the page re-scope every number to a single origin; pick the one closest to where your requests originate.
How is Astar Network RPC latency measured here?
One identical JSON-RPC POST (`eth_getBlockByNumber`) every 60 seconds against each provider from each of 3 regions. Responses are classified so an endpoint stuck on an old head or returning errors is never ranked as fastest.
