Astar public RPC endpoints, tested
Every keyless Astar (chain ID 592) endpoint listed on Chainlist and chainid.network, tested the same way on 2026-11-08: does it answer on the right chain, how fast, how far behind the best head, how large an eth_getLogs range it accepts, whether it keeps archive state, and whether its WebSocket actually streams. 3 of 10 HTTP endpoints were working.
Working HTTP endpoints
| Endpoint | Latency | Behind best | eth_getLogs | State |
|---|---|---|---|---|
| https://astar.api.onfinality.io/public | 103 ms | 0 blocks | 1,000 | archive (1M+) |
| https://rpc.swiftnodes.io/rpc/astar (SwiftNodes, keyless: 2 req/s) | 151 ms | 0 blocks | under 1,000 | recent only |
| https://evm.astar.network | 17 ms | 14976 blocks | 1,000 | archive (1M+) |
Order: endpoints within 3 blocks of the best head first, then by median latency. Latency is measured from one server, so yours will differ by region; lag and limits do not.
WebSocket endpoints
