About Linea

Linea launched mainnet in July 2023. It's a zk-rollup with EVM equivalence — Solidity contracts deploy without changes. ConsenSys operates the prover and sequencer, with plans to decentralize over time.

Linea's competitive advantage is its tight integration with MetaMask (used by hundreds of millions of users) and Infura (RPC infrastructure). MetaMask's built-in swap/bridge features default to Linea for many flows, driving organic user acquisition.

Common Use Cases on Linea

  • MetaMask-integrated dApps and onchain commerce
  • DeFi (Aave V3, Lynex, Mendi)
  • Cross-chain applications requiring fast L1 finality
  • Onchain games leveraging cheap gas + Ethereum security
  • Identity and onchain reputation (ConsenSys ecosystem)

Linea Ecosystem

Mendi (lending), Lynex (DEX), Aave V3, Uniswap V3. Strong incentive programs have driven TVL growth. MetaMask integration provides a unique user-acquisition channel.
