Base vs zkSync Era
Base leads on both live benchmarks. Base wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (1.93 s vs 5.44 s), Cheapest blockchain transaction fee, live across 15 L1 and L2 chains ($0.000240 vs $0.00181).
Base
Coinbase-operated optimistic rollup on the OP Stack. 2-second sequencer block time, shared bridge with Optimism via the OP Superchain, fastest-growing L2 by TVL since 2024.
zkSync Era
Matter Labs' zk-rollup with the ZK Stack reference implementation and a custom LLVM-based VM (EraVM). Batched producer with variable block cadence (p50 ~3-6 s) tied to proof generation rather than fixed sequencer intervals.

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.
