Arbitrum vs Mantle
Arbitrum leads on 3 of 4 shared benchmarks, Mantle on 1. Arbitrum wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (259 ms vs 1.80 s), Fastest Chainlink CCIP source chain by end-to-end delivery latency (19.0 min vs 25.0 min), Fastest LayerZero source chain by end-to-end message delivery (31.71 s vs 1.1 min). Mantle wins on Cheapest blockchain transaction fee, live across 15 L1 and L2 chains ($0.000436 vs $0.000822).
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.
Mantle
Modular OP Stack fork using EigenDA for data availability rather than Ethereum calldata, cutting L1 anchoring cost. 2-second sequencer block time, MNT token for gas (ETH-pegged).

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.
