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 2026-10-11: 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. 6 of 10 HTTP endpoints were working.

Working HTTP endpoints

Endpoint	Latency	eth_getLogs	State
https://docs-demo.nova-mainnet.quiknode.pro	15 ms	10,000+	archive (1M+)
https://arbitrum-nova-rpc.publicnode.com	31 ms	10,000+	recent only
https://arbitrum-nova.drpc.org	42 ms	under 1,000	recent only
https://rpc.swiftnodes.io/rpc/arbitrum-nova (SwiftNodes, keyless: 2 req/s)	56 ms	10,000+	recent only
https://lb.routeme.sh/rpc/evm/42170	90 ms	under 1,000	none
https://nova.arbitrum.io/rpc	118 ms	1,000	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.
