Neutron RPC endpoints: free public URLs by latency
HTTP round-trip latency for the Tendermint `status` method against every free, no-key public Neutron Cosmos SDK endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Stake&Relax has the lowest median latency of the 3 free public Neutron RPC endpoints measured, 114 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/neutron-rpc. 3 public endpoints, no key: neutron-rpc.stakeandrelax.net, rpc.lavenderfive.com, neutron-rpc.polkachu.com. Full URLs with their 24h median are listed below.

Neutron is a Cosmos SDK smart-contract chain running CosmWasm, secured by Cosmos Hub validators via Interchain Security. Same Tendermint `status` probe used on the rest of the Cosmos cluster; every provider live-verified with 4 consecutive keyless probes at launch. Neutron's official `rpc-kralum.neutron-1.neutron.org` endpoint returned an SSL handshake failure during the launch audit and was excluded; it will be re-audited when the TLS chain is fixed.
Methodology
Neutron: 3 free public RPC endpoints answering `status` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. Stake&Relax leads at 114 ms. We measure the round-trip latency of a single, identical JSON-RPC call (Tendermint `status`) against every no-key public Neutron endpoint that sustains continuous probing, 3 providers live today, every 60 seconds, from us-east, eu-west and Singapore. The harness classifies every response (ok / http_err / jsonrpc_err / stale / timeout) with a Neutron-scaled staleness gap (40 blocks at Neutron's ~2 s block time). The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Neutron-scoped answer with per-region breakdowns as a first-class dimension.
