Plasma public RPC endpoints, tested

Every keyless Plasma (chain ID 9745) 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. 2 of 7 HTTP endpoints were working.

Working HTTP endpoints

EndpointLatencyBehind besteth_getLogsState
https://rpc.plasma.to5 ms0 blocks10,000+archive (1M+)
https://rpc.swiftnodes.io/rpc/plasma (SwiftNodes, keyless: 2 req/s)34 ms5 blocks10,000+archive (1M+)

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.
