Arbitrum leads on 2 of 6 shared benchmarks, Robinhood Chain on 4. Arbitrum wins on Bridged TVL by chain ($7.49B vs $1.82B), Stablecoin flow by chain ($57.25M vs $1.40M). Robinhood Chain wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 6 more (88 ms vs 346 ms), Cheapest blockchain transaction fee, live across L1 and L2 chains ($0.00100 vs $0.00102), Fastest Chainlink CCIP source chain by end-to-end delivery latency (17.3 min vs 18.1 min), Fastest LayerZero source chain by end-to-end message delivery (14.30 s vs 24.30 s). Data as of 2026-10-24 UTC.
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.

| Provider | Bridged TVL | Bridged share | 7d change | 7d vs peers | Native | Canonical | External |
|---|---|---|---|---|---|---|---|
| Arbitrum | $7.49B | 74.3% | - | - | $2.59B | $3.33B | $4.15B |

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.
| Provider | Net stablecoin flow (30d) | 30d change | Stablecoin float | Net 7d | 7d change |
|---|---|---|---|---|---|
| Arbitrum | $57.25M | 1.55% | $3.74B | - | - |
| Robinhood Chain | $1.40M | 0.13% | $1.08B | - | - |
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.

On the Bridged TVL by chain benchmark, Arbitrum leads at $7.49B versus Robinhood Chain at $1.82B. Live measurement is updated continuously by the OpenChainBench harness.
On the Fastest L2 block time, live across Robinhood, Arbitrum, Base and 6 more benchmark, Robinhood Chain leads at 88 ms versus Arbitrum at 346 ms. Live measurement is updated continuously by the OpenChainBench harness.
Every benchmark on this page uses the same open methodology, published at https://openchainbench.com/methodology. Data is CC-BY-4.0. Measurement harnesses are MIT-licensed.
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.
