Liquidity pools for v4 are now live via the web app, with swaps set to go live within the next few days.

According to the team, this upgrade transforms Uniswap into a developer-friendly platform. The core feature of v4 is the introduction of “hooks”—customizable smart contracts that allow for fine-tuned settings on liquidity pools, swaps, fees, and order interactions.

Uniswap Labs emphasized that v4 is the most cost-efficient version of the protocol to date. The cost of creating liquidity pools is reduced by 99.9% compared to Uniswap v3, while multi-address swaps will be cheaper for users.

The update was built with input from hundreds of community members, according to the team.

The code has undergone 9 security audits, and a $15.5 million bug bounty program was conducted. No critical vulnerabilities were found.

In July 2023, Uniswap Labs announced that Uniswap v4 would launch within four months after the Ethereum Dencun hard fork.

Shortly before that, the team had released a “draft” version of the v4 code, which was still pending audits and refinements.

Reminder: According to dYdX analysts, the DEX derivatives trading volume is projected to hit $3.48 trillion in 2025.
