Mantle vs OP Mainnet

Mantle is a modular Ethereum Layer‑2 that decouples execution, data availability and settlement, using Optimistic rollup proofs on Ethereum mainnet and EigenDA for cheap blob‑based data. Its BitDAO‑backed treasury subsidises sequencer fees, keeping swaps under $0.05 even during L1 congestion. The network went live in July 2023 and now hosts over 150 dApps including the Mantle DEX and Fusion perpetuals.

OP Mainnet (Optimism) is an optimistic rollup that batches transactions to Ethereum and relies on fraud proofs submitted during a seven‑day challenge window. The Bedrock upgrade in 2023 cut L1 calldata costs by 40 % and introduced multi‑proof modularity. ‘RetroPGF’ rounds redistribute protocol revenue to public‑goods builders, governed by the OP token‑holder Collective.
