Astar Network RPC endpoints: free public URLs by 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 is the only free public Astar Network RPC endpoint measured, at 49 ms (p50, 24h, 3 regions). 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. OnFinality and 1RPC provide keyless access probed every 60 seconds from three regions. PublicNode returned 404 and BlastAPI's DNS is dead.
Methodology
Astar Network: 1 free public RPC endpoints answering `eth_getBlockByNumber` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. OnFinality leads at 49 ms. 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, 1 providers, 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
Which Astar Network RPCs work without an API key?
1 endpoints sustain continuous keyless probing, each listed with its URL in the endpoints table above. PublicNode returned 404 and BlastAPI's DNS is dead; both were removed.
