Uniswap has deployed v2, v3 and v4 on Consensys’ Linea zkEVM, bringing its full DEX stack to a low-fee, EVM-equivalent rollup now integrated across the Uniswap app, API and wallet.

Uniswap has announced that Uniswap v2, v3 and v4 are now live on Linea, adding support for the Consensys-built zkEVM Layer 2 network across its core protocol stack. The deployment means traders and liquidity providers can now access familiar Uniswap pools and routing logic on a rollup that offers sub-cent fees, fast finality and Ethereum-level security.

According to Uniswap Labs, Linea is already integrated into the Uniswap web application and Uniswap API, giving aggregators, front ends and bots access to the new L2 without changing their existing tooling. Support in Uniswap Wallet on iOS and Android is being phased in, extending the mobile app’s current coverage — which includes Ethereum mainnet and other L2s — to Linea as availability is approved in each app store region.

Linea’s zkEVM stack under Uniswap

Linea is a Type 2 zkEVM rollup developed by Consensys to bring EVM-equivalent execution and zk-rollup security guarantees to Ethereum. Consensys describes Linea as combining Ethereum-grade security with ultra-low transaction costs and rapid block finality, while keeping full compatibility with existing Solidity contracts and developer tools.

Because Linea is EVM-equivalent and uses ETH for gas, Uniswap’s contracts can be deployed with minimal changes, allowing the same v2 AMM, concentrated liquidity design of v3, and hook-enabled architecture of v4 to function on the L2 as they do on mainnet. Earlier governance discussions between Consensys and the Uniswap community laid the groundwork for the deployment, positioning Linea as a strategic rollup within the broader Uniswap ecosystem.

Multichain reach and lower-fee DeFi

The Linea launch adds another scaling venue to Uniswap’s roster alongside existing deployments on networks such as Arbitrum, Optimism and Polygon. For users, it opens up the possibility of swapping and providing liquidity with lower gas costs while still settling to Ethereum security, and for developers it offers a new environment where Uniswap can anchor DeFi apps, wallets and integrations tied into the Consensys toolchain.

As zkEVM rollups mature, Uniswap’s presence on Linea is likely to serve as both a liquidity magnet and a benchmark for how much activity major DEXs can attract to L2s built around deep infrastructure integrations with incumbents like Consensys.
