Cronos public RPC endpoints, tested
Every keyless Cronos (chain ID 25) 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. 7 of 16 HTTP endpoints were working.
Working HTTP endpoints
| Endpoint | Latency | Behind best | eth_getLogs | State |
|---|---|---|---|---|
| https://api-cronos-mainnet-archive.n.dwellir.com/2ccf18bf-2916-4198-8856-42172854353c | 144 ms | 0 blocks | under 1,000 | none |
| https://cronos-evm-rpc.publicnode.com | 17 ms | 49 blocks | 10,000+ | none |
| https://cronos.drpc.org | 23 ms | 45 blocks | under 1,000 | archive (1M+) |
| https://evm.cronos.org | 42 ms | 51 blocks | 1,000 | archive (1M+) |
| https://rpc.vvs.finance | 68 ms | 41 blocks | 1,000 | archive (1M+) |
| https://cronos.rpc.sentio.xyz | 166 ms | 25 blocks | 10,000+ | archive (1M+) |
| https://rpc.swiftnodes.io/rpc/cronos (SwiftNodes, keyless: 2 req/s) | 176 ms | 6 blocks | 10,000+ | none |
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.
