Key Takeaways
- Uniswap v4 goes live with Ethereum, Arbitrum, OP Mainnet, and Base support.
- New “hooks” contracts enable custom pool interactions, deeper liquidity, and more transactions.
- Lower gas fees make v4 the most cost-efficient version of Uniswap.
Uniswap Labs has officially launched Uniswap v4, the latest iteration of its decentralized exchange protocol. The upgrade supports Ethereum, Arbitrum, OP Mainnet, and Base, and its exchange function will roll out in the coming days.
This version introduces “hooks” contracts, allowing developers to tailor interactions within liquidity pools, exchanges, fees, and liquidity provider (LP) positions. The added flexibility is expected to drive deeper liquidity and more transactions.
According to the announcement, the protocol’s previous versions—v2 and v3—have collectively processed over $2.75 trillion in trading volume without a single hack.
The latest release expands network compatibility, going live on Ethereum, Polygon, BNB Chain, Avalanche, and several other chains. Users can already provide liquidity through the Uniswap web app while swapping functionality will be gradually enabled as liquidity transitions to v4.
Uniswap v4 Introduces Developer-Friendly “Hooks”
Uniswap v4 reimagines the protocol in terms of a developer platform with added customizability. With new hooks—reusable, modular plugins for manipulating pools, fees, and LP positions—developers have new options for DeFi use cases. There have been over 150 developed, including fee dynamics and liquidity management automation.
By granting developers direct access to try out, v4 accelerates integration and innovation. Greater liquidity and swap activity, in return, deepen its overall network effects, with the protocol foreseeing them. Hook flexibility has, in fact, prompted out-of-the-box thinking, with even more in store for future development, with v4 taking off.
Enhanced Efficiency and Security
Adaptability is not all about Uniswap v4, but it is about significant cost savings, too. Costs for new pool creation have reduced between 99.99%, and multi-hop trading comes with lowered gas fees. Natively supported ETH reduces even additional expenses for ETH-related actions.
Security is a top priority, with v4 having been subjected to deep audits. Codebase has been examined through nine audits, a $2.35 million security challenge, and a record bug bounty of up to $15.5 million for critical vulnerabilities. To date, no critical security vulnerabilities have been discovered.
Now, it is in 10 chains, with full feature rollout in preparation soon. Existing positions can migrate, and new ones can be added through liquidity providers’ hooks. Developers can follow integration guides in an effort to utilize v4’s capabilities, opening a new era for Uniswap’s ecosystem.
