Arc public RPC endpoints, tested
Every keyless Arc (chain ID 5042) 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. 10 of 10 HTTP endpoints were working.
Working HTTP endpoints
| Endpoint | Latency | Behind best | eth_getLogs | State |
|---|---|---|---|---|
| https://rpc-arc.blockmachine.io | 32 ms | 0 blocks | under 1,000 | recent only |
| https://arc-rpc.blockreq.com/v1/rpc/public | 39 ms | 2 blocks | 1,000 | recent only |
| https://arc-rpc.publicnode.com | 40 ms | 1 blocks | 1,000 | none |
| https://rpc.blockdaemon.mainnet.arc.io | 8 ms | 10 blocks | 10,000+ | recent only |
| https://arc.drpc.org | 25 ms | 5 blocks | under 1,000 | archive (1M+) |
| https://rpc.drpc.mainnet.arc.io | 37 ms | 9 blocks | under 1,000 | archive (1M+) |
| https://rpc.quicknode.mainnet.arc.io | 39 ms | 10 blocks | 1,000 | archive (1M+) |
| https://rpc.swiftnodes.io/rpc/arc (SwiftNodes, keyless: 2 req/s) | 93 ms | 11 blocks | under 1,000 | archive (1M+) |
| https://rpc.mainnet.arc.io | 113 ms | 15 blocks | 1,000 | archive (1M+) |
| https://rpc.beamrpc.com | 130 ms | 4 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.
