Cronos zkEVM RPC endpoints: free public URLs by latency
HTTP round-trip latency for eth_getBlockByNumber against every free, no-key public Cronos zkEVM endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Cronos (Crypto.com) has the lowest median latency of the 2 free public Cronos zkEVM RPC endpoints measured, 160 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/cronos-zkevm-rpc. 2 public endpoints, no key: mainnet.zkevm.cronos.org, cronos-zkevm.drpc.org. Full URLs with their 24h median are listed below.

Cronos zkEVM (chain 388) is Crypto.com's zkEVM Layer 2 built on the zkSync Era stack, distinct from Cronos EVM. CRO is the bridged gas token. 2 keyless endpoints are probed continuously: the Cronos official mainnet gateway (mainnet.zkevm.cronos.org) and dRPC (cronos-zkevm.drpc.org).
Methodology
Cronos zkEVM: 2 free public RPC endpoints answering `eth_getBlockByNumber` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. Cronos (Crypto.com) leads at 160 ms; the chain-official endpoint measures 160 ms. We measure the round-trip latency of a single, identical RPC call (`eth_getBlockByNumber`) against every no-key public Cronos zkEVM endpoint that sustains continuous probing, 2 providers live today, every 60 seconds, from us-east, eu-west and Singapore. The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Cronos zkEVM-scoped answer with per-region breakdowns as a first-class dimension.
