Sonic public RPC endpoints, tested

Every keyless Sonic (chain ID 146) 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. 7 of 15 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.

WebSocket endpoints

  • streams sonic-rpc.publicnode.com: first head after 2060 ms
  • streams sonic.drpc.org: first head after 3589 ms
  • does not stream rpc.swiftnodes.io/ws/sonic (SwiftNodes): subscribe rejected: WebSocket subscriptions require an API key. Get a free key at https://swiftnodes
