Mantle vs Optimism
Split decision: Mantle leads on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (1.81 s vs 1.96 s) and Fastest LayerZero source chain by end-to-end message delivery (59.06 s vs 1.3 min); Optimism leads on Fastest Chainlink CCIP source chain by end-to-end delivery latency (17.5 min vs 21.4 min) and Fastest Axelar GMP source chain by end-to-end delivery (25.6 min vs 50.0 min).
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).
Optimism
Optimistic rollup and the canonical OP Stack reference implementation. 2-second sequencer block time, 7-day fraud-proof window, anchored to Ethereum L1 via batch submissions to the Optimism Portal.

How this pair was selected
Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing — panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
