Mantle vs Sonic

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.

Sonic is an ultra‑fast EVM Layer‑1 claimed to reach 400k TPS and sub‑second finality via a custom SonicVM and DAG‑based consensus dubbed Tempo. Blocks are final once two‑thirds of stake attest, and state is stored in an in‑memory ledger that snapshots to disk every epoch. The project focuses on GameFi and real‑time social dApps, with an incentive testnet launched in May 2025.
