Soneium public RPC endpoints, tested

Every keyless Soneium (chain ID 1868) endpoint listed on Chainlist and chainid.network, tested the same way on 2026-10-11: 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.

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.
