Uniswap Labs, the leader in decentralized exchange protocols, has unveiled the highly anticipated Uniswap v4 on Friday.
The new version promises to offer greater flexibility and innovative features for both developers and users.
Described by Uniswap founder and CEO Hayden Adams as “a new era of DeFi,” the launch follows an extensive series of preparations, including a record-breaking $15.5 million bug bounty program, nine security audits, and a $2.35 million security competition.
Uniswap v4 is now live across 12 blockchain networks, including Ethereum, Polygon, Arbitrum, BNB Chain, and Avalanche, among others. This expansion includes Layer-2 solutions like Arbitrum and Base, bringing faster and more cost-effective transactions to the platform. The update introduces a 99.99% reduction in costs for liquidity pools alongside new features, such as modular hooks that enable developers to customize pools, fees, and swap structures.
The launch of Uniswap v4 follows the introduction of Uniswap’s own Layer-2 scaling chain, Unichain, in October 2023. Unichain aims to enhance cross-chain interoperability and provide faster, cheaper transactions.
While Uniswap v4 presents a major upgrade, the protocol’s previous versions, V2 and V3, have already facilitated over $2.75 trillion in token swaps.
