Robinhood Chain wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 6 more (88 ms vs 1.91 s), Fastest Chainlink CCIP source chain by end-to-end delivery latency (17.3 min vs 17.5 min), Fastest LayerZero source chain by end-to-end message delivery (14.30 s vs 1.5 min), Bridged TVL by chain ($1.82B vs $1.46B). Data as of 2026-10-24 UTC.
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.
Robinhood Chain
Robinhood is a US commission-free investing app with 25M+ funded accounts. It added crypto trading in 2018, launched its own L2 chain (Robinhood Chain) in 2025, and is the #1 most-reviewed financial app on the US App Store with nearly 5 million ratings.

Bridged TVL by chain: how much of a chain's capital came from somewhere else

Bridged TVL is value secured by the chain's bridge, not value locked in its DeFi protocols; a chain can rank high on one and low on the other. The split is L2Beat's: canonical is escrowed on the host chain by the chain's own contracts, external came through a third-party bridge, native was minted here. Rows are the chains L2Beat tracks in its scaling summary; a settled L1 has no row by construction, not by omission. Size is not quality: a large balance says capital came, not that it stayed.
Stablecoin flow by chain: where dollars actually moved over 30 days

Stablecoin float is where dollars are parked, not what they do. A chain can take in a billion that sits idle, and lose float to a single issuer redeeming. The figure is DefiLlama's chain-wide pegged-USD aggregate, every issuer combined; it does not separate a bridge inflow from a native mint, and a dollar bridged to an L2 counts on both chains, so rows are not additive. Read the net dollars with the percentage beside them: the same $400M is a rounding error on Ethereum and a doubling elsewhere.

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.
