Arbitrum Nova public RPC endpoints, tested
Every keyless Arbitrum Nova (chain ID 42170) 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. 5 of 10 HTTP endpoints were working.
Working HTTP endpoints
| Endpoint | Latency | Behind best | eth_getLogs | State |
|---|---|---|---|---|
| https://docs-demo.nova-mainnet.quiknode.pro | 13 ms | 0 blocks | 10,000+ | archive (1M+) |
| https://arbitrum-nova-rpc.publicnode.com | 17 ms | 0 blocks | 10,000+ | recent only |
| https://arbitrum-nova.drpc.org | 22 ms | 0 blocks | under 1,000 | recent only |
| https://nova.arbitrum.io/rpc | 122 ms | 0 blocks | 1,000 | recent only |
| https://rpc.swiftnodes.io/rpc/arbitrum-nova (SwiftNodes, keyless: 2 req/s) | 123 ms | 0 blocks | 10,000+ | recent only |
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.
