Soneium public RPC endpoints, tested
Every keyless Soneium (chain ID 1868) endpoint listed on Chainlist and chainid.network, tested the same way on 2026-09-24: 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. 5 of 6 HTTP endpoints were working.
Working HTTP endpoints
| Endpoint | Latency | Behind best | eth_getLogs | State |
|---|---|---|---|---|
| https://rpc.swiftnodes.io/rpc/soneium (SwiftNodes, keyless: 2 req/s) | 248 ms | 1 blocks | 10,000+ | none |
| https://rpc.nodeflare.app/soneium/public | 551 ms | 0 blocks | 1,000 | recent only |
| https://rpc.soneium.org | 24 ms | 7 blocks | 10,000+ | archive (1M+) |
| https://soneium.drpc.org | 24 ms | 5 blocks | under 1,000 | archive (1M+) |
| https://soneium-mainnet.rpc.sentio.xyz | 166 ms | 4 blocks | 10,000+ | 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.
