opBNB public RPC endpoints, tested
Every keyless opBNB (chain ID 204) 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. 8 of 12 HTTP endpoints were working.
Working HTTP endpoints
| Endpoint | Latency | Behind best | eth_getLogs | State |
|---|---|---|---|---|
| https://api-opbnb-mainnet.n.dwellir.com/2ccf18bf-2916-4198-8856-42172854353c | 50 ms | 0 blocks | under 1,000 | none |
| https://rpc.swiftnodes.io/rpc/opbnb (SwiftNodes, keyless: 2 req/s) | 9 ms | 22 blocks | under 1,000 | none |
| https://opbnb.drpc.org | 90 ms | 127 blocks | under 1,000 | none |
| https://opbnb.api.pocket.network | 95 ms | 107 blocks | 10,000+ | none |
| https://opbnb-mainnet-rpc.bnbchain.org | 102 ms | 142 blocks | 10,000+ | none |
| https://opbnb-rpc.blockreq.com/v1/rpc/public | 119 ms | 114 blocks | 1,000 | none |
| https://opbnb-mainnet.nodereal.io/v1/e9a36765eb8a40b9bd12e680a1fd2bc5 | 144 ms | 106 blocks | 10,000+ | archive (1M+) |
| https://opbnb-rpc.publicnode.com | 250 ms | 124 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.
