Sonic public RPC endpoints, tested
Every keyless Sonic (chain ID 146) 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. 9 of 14 HTTP endpoints were working.
Working HTTP endpoints
| Endpoint | Latency | Behind best | eth_getLogs | State |
|---|---|---|---|---|
| https://lb.routeme.sh/rpc/evm/146 | 29 ms | 0 blocks | under 1,000 | none |
| https://rpc.nodeflare.app/sonic/public | 61 ms | 1 blocks | under 1,000 | recent only |
| https://sonic-rpc.publicnode.com | 15 ms | 11 blocks | 10,000+ | archive (1M+) |
| https://rpc.soniclabs.com | 39 ms | 12 blocks | 10,000+ | archive (1M+) |
| https://sonic.api.pocket.network | 39 ms | 9 blocks | under 1,000 | none |
| https://sonic.drpc.org | 42 ms | 10 blocks | under 1,000 | archive (1M+) |
| https://sonic-json-rpc.stakely.io | 85 ms | 13 blocks | 10,000+ | archive (1M+) |
| https://sonic-mainnet.rpc.sentio.xyz | 167 ms | 8 blocks | 10,000+ | archive (1M+) |
| https://rpc.swiftnodes.io/rpc/sonic (SwiftNodes, keyless: 2 req/s) | 221 ms | 5 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.
