The Uniswap community has voted in favor of deploying Uniswap v3 smart contracts on the Polygon PoS blockchain, marking the latest expansion of the leading DEX into layer-2 ecosystems. Uniswap Labs confirmed via Twitter on December 18 that the contracts will be deployed within “a few days.”
Uniswap v3 Adds Third L2 Network
With a daily trading volume of $1.5 billion and a total value locked of $8.6 billion, Uniswap v3 is the second-largest DeFi protocol by TVL after Curve Finance ($21.8 billion). The exchange already supports Arbitrum One and Optimism, both using optimistic rollups to slash fees. On Ethereum mainnet, swapping tokens costs roughly $31.74, compared to $2.63 on Arbitrum and $2.29 on Optimism. Polygon PoS, a sidechain with its own consensus, offers even lower fees and faster finality.
Polygon CEO Mihailo Bjelic Makes the Case
Polygon CEO Mihailo Bjelic submitted the governance proposal on November 20, arguing that Polygon PoS is “battle-tested” and aligned with Ethereum values. Community supporters echoed the sentiment, with one noting: “ETH fees are killing all of us. Polygon is a battle-tested solution that can save users from slow transactions and high fees.”
Polygon already hosts platforms like Curve, Aave, and OpenSea. It recently launched a $200 million fund for Web3 social media, acquired Hermez Network for $250 million (now Polygon Hermez), and purchased Mir protocol for $400 million. The addition of Uniswap v3 is expected to further boost liquidity and user adoption on Polygon, providing a seamless, low-cost trading experience.
