Following the success of v2 and v3, which processed over $2.75 trillion in volume without ever being hacked, the new version offers greater efficiency and customization. The protocol is active as of now on all major blockchains, such as Ethereum, Polygon, Arbitrum, OP Mainnet, Base, BNB Chain, Blast, World Chain, Avalanche and Zora Network.

Among the main new features, new hooks are now available. These modular tools allow you to customize liquidity pools, swaps and fees in a flexible way. It will be possible to use “Limit” orders, of “Time Weighted Average Market Maker” trades, and also make non-productive liquidity, “Out of Range” efficient.

Among other new features, the costs of creating liquidity pools will be reduced by 99.9%. It will also be possible to use ETH again for trading without the need to use the “wrapped” version wETH.

Security, audits and the future of the Uniswap ecosystem

Security was a top priority for this update.

The code passed nine independent audits and a $2.35 million security competition. In addition, the largest bug bounty in history was offered, with a $15.5 million reward .

The release of Uniswap v4 not only improves efficiency, but opens up new development opportunities. Uniswap to date, has created a true ecosystem, also accomplice to the work done on the proprietary layer 2 “Unichain”, scheduled for mainnet by current quarter.

The market has not reacted to an already expected news that does not directly impact the UNI token. UNI ‘s price remains at $12.5, up +4% on the daily but at a -5% from early 2025.
