Flare vs Mantle

Flare is an EVM-compatible Layer 1 blockchain built to provide decentralized access to high-integrity data from other blockchains and the internet. Through native protocols such as the Flare Data Connector and Flare Time Series Oracle, it enables developers to build data-intensive applications, cross-chain services, and decentralized finance products. Flare’s architecture is designed to enhance interoperability while bringing smart contract functionality to assets and ecosystems beyond Ethereum.

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.
