Uniswap (UNI) Deploys All Protocol Versions on Consensys Linea L2

Uniswap (UNI) has launched all three protocol versions—v2, v3, and v4—on Linea, the zkEVM Layer 2 built by Consensys. The deployment makes Uniswap's full liquidity stack available on yet another Ethereum scaling solution, with immediate access through the Uniswap Web App and API. Mobile wallet support for iOS and Android is rolling out now.

Linea sits at a $75.8 million market cap with LINEA trading at $0.003034, up 1.68% over the past 24 hours. The network has seen growing institutional interest, including a $200 million ETH allocation from Sharplink in early March.

What Linea Brings to the Table

Unlike optimistic rollups, Linea uses zero-knowledge proofs to validate transactions off-chain before posting to Ethereum mainnet. The practical result: faster finality and lower gas costs without the typical seven-day withdrawal window.

The network runs a dual-burn mechanism that creates deflationary pressure on LINEA tokens. A portion of transaction fees gets burned directly in ETH, while the remainder buys and burns LINEA. Bridged ETH also generates native staking yield that flows back into the ecosystem—a feature that could attract yield-seeking LPs.

Full EVM equivalence means existing Ethereum contracts deploy without modification. For Uniswap users, the interface stays identical to what they'd find on mainnet, Base, or Unichain.

Developer Access

The Uniswap API now supports Linea directly, giving builders and institutions access to protocol liquidity without custom integration work. Free API keys are available immediately. Developers can also tap into Uniswap Skills—pre-built tools designed for integrating the protocol into AI agents and applications.

This follows Linea's recent ecosystem expansion. Status added chain support on March 20, signaling growing wallet infrastructure around the network.

How to Use It

Swapping requires selecting Linea from the network dropdown in either the web app or wallet. Liquidity provision works through the Pools page—choose Linea, pick your token pair and fee tier, then confirm.

For LPs weighing options, Linea's native yield mechanics on bridged ETH could provide additional returns beyond standard trading fees. The zkEVM architecture also means faster transaction confirmations compared to optimistic alternatives, reducing the window for impermanent loss during volatile periods.

Uniswap's expansion to Linea marks its continued push across the L2 landscape. With Consensys backing and growing institutional capital flowing into the network, liquidity providers now have another venue to consider—one with built-in deflationary tokenomics and yield generation baked into the infrastructure layer.
