Mantle vs Optimism
Mantle leads on 2 of 6 shared benchmarks, Optimism on 4. Mantle wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (1.85 s vs 1.94 s), Fastest LayerZero source chain by end-to-end message delivery (52.50 s vs 2.3 min). Optimism wins on Cheapest blockchain transaction fee, live across L1 and L2 chains ($0.0000026 vs $0.000597), Fastest Chainlink CCIP source chain by end-to-end delivery latency (17.9 min vs 25.0 min), Fastest Axelar GMP source chain by end-to-end delivery (25.0 min vs 45.0 min), Bridged TVL by chain ($1.61B vs $1.33B). Data as of 2026-10-11 UTC.
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.

Bridged TVL by chain: how much of a chain's capital came from somewhere else
Blockchains| Provider | Bridged TVL | Bridged share | 7d change | 7d vs peers | Native | Canonical | External |
|---|---|---|---|---|---|---|---|
| Mantle | $1.33B | 96.7% | - | - | $44.91M | $680.68M | $647.59M |
| Optimism | $1.61B | 79.8% | 0.69% | 3.04% | $409.48M | $1.29B | $321.05M |

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
Blockchains| Provider | 30d change | Stablecoin float | Net 7d | 7d change |
|---|---|---|---|---|
| Mantle | - | $553.38M | - | - |
| Optimism | 31.6% | $632.96M | $63.26M | 11.1% |

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.
