Arbitrum vs Lava
Arbitrum leads on 2 of 2 shared benchmarks, Lava on 0. Arbitrum wins on Fastest free public RPC for Ethereum, BNB, Polygon and 7 more EVM chains (244 ms vs 380 ms), Fastest free Arbitrum RPC, live no-key endpoint latency (244 ms vs 400 ms).
Arbitrum
Optimistic rollup built on Nitro stack with a fast-finality sequencer. Sub-second block times (~250 ms) via a 250 ms default block interval, far below the 2 s OP Stack convention. 7-day fraud-proof window for L1 finality.
Lava
Lava Network is a decentralized RPC mesh with permissionless validators. Public no-key endpoints work for Ethereum (`eth1.lava.build`) and Arbitrum (`arb1.lava.build`); other chains require an account-issued key.

How this pair was selected
A pair is published when all four conditions hold. Both providers run in the same OpenChainBench benchmark for at least seven consecutive days. Each provider has at least 1000 samples in the measurement window. The head to head query has observable third party search demand. Both providers have a public /products/[slug] page on OCB. The full pair ledger is versioned in the public repo so the methodology is externally verifiable.
