Mantle vs Stellar

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.

Stellar is a payments‑focused blockchain that uses the Stellar Consensus Protocol (SCP), a federated Byzantine agreement where each node chooses its own quorum slices. Anchors issue fiat‑backed tokens, and Stellar’s built‑in DEX offers path payments that can hop through multiple assets in a single transaction. The 2023 Soroban upgrade added WebAssembly smart contracts, enabling on‑chain AMMs, lending and other DeFi primitives.
