opBNB public RPC endpoints, tested
Every keyless opBNB (chain ID 204) endpoint listed on Chainlist and chainid.network, tested the same way on 2026-10-04: 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. 8 of 12 HTTP endpoints were working.
Working HTTP endpoints
| Endpoint | Latency | Behind best | eth_getLogs | State |
|---|---|---|---|---|
| https://opbnb.api.pocket.network | 70 ms | 0 blocks | 10,000+ | none |
| https://opbnb-rpc.publicnode.com | 23 ms | 12 blocks | 10,000+ | none |
| https://opbnb.drpc.org | 41 ms | 8 blocks | under 1,000 | none |
| https://rpc.swiftnodes.io/rpc/opbnb (SwiftNodes, keyless: 2 req/s) | 66 ms | 21 blocks | 10,000+ | none |
| https://opbnb-mainnet-rpc.bnbchain.org | 102 ms | 22 blocks | 10,000+ | none |
| https://opbnb-mainnet.nodereal.io/v1/64a9df0874fb4a93b9d0a3849de012d3 | 108 ms | 20 blocks | 10,000+ | archive (1M+) |
| https://opbnb-mainnet.nodereal.io/v1/e9a36765eb8a40b9bd12e680a1fd2bc5 | 108 ms | 19 blocks | 10,000+ | archive (1M+) |
| https://public.1rpc.io/opbnb | 110 ms | 6 blocks | under 1,000 | 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.
