In a major turnaround for the decentralized finance (DeFi) scene, Uniswap has disclosed its v4 upgrade, presenting with it a revolutionary feature called “Hooks.”
This momentous change is not merely a slight tweak or two; it is a serious rethinking of what DEXs can be. With v4, Uniswap is no longer just an automated market maker (AMM); it has become a highly flexible modular liquidity engine that can do a whole lot more than just what we used to imagine DEXs can do.
Introducing Hooks: A Programmable Future for Liquidity
The v4 upgrade of Uniswap brings to life the programmable nature of a liquidity pool through the introduction of Hooks. In essence, Hooks allows Uniswap to become a highly flexible and programmable liquidity protocol, which lets developers create unique and varied strategies for not just liquidity provision but for trading and yield optimization as well. Once static and relatively rigid, liquidity pools are now also fully programmable, which empowers users to better fine-tune not just the operation of the pools but the environment in which they operate. This is a game-changer for the world of AMMs.
The innovation at the heart of this is the ability for developers to create custom strategies that are just right for their specific use cases. Hooks let developers do a number of important things. First, they let them automate a lot of what we do today to keep our investments on track (think of rebalancing portfolios), and they let them internalize the profits they make when they execute certain trades (that’s called miner-extractable value, or MEV). These new capabilities give liquidity providers (LPs) and traders who use Uniswap a way to have control over their liquidity provision that was literally impossible until just a few months ago.
In addition, introducing these customizable strategies can lead to improved yield optimization for LPs, thereby driving extra participation and liquidity in the platform. For users who want to maximize returns from their assets, Uniswap v4 offers an unprecedented level of control and flexibility. And with the addition of Hooks, deploying custom strategies has never been easier for developers. All this clearly broadens the space for innovation in DeFi.

The Singleton Model: Lowering Costs and Enhancing Efficiency
Uniswap v4 brings alongside its introduction of Hooks the potential for significantly reduced gas fees across its platform with the Singleton model. This model merges all the pools into a single contract. The need for multiple, separate contracts for each pool has gone away. Uniswap now operates much like a DApp with a single contract at the core of its operation. And it gives users much better pricing on their swaps. (Also: the better price you get, the less you pay for gas.)
Given that Uniswap allows for much more efficient contract interaction while operating under much less gas, you should be able to make a swap at a price that works out to be better than what you would receive under its previous versions.
Not just small improvements, the gas fee savings can potentially lead to a fundamental change in user interaction with the platform. For the trading-against-ETH set of instructions, we save on gas fees because those instructions are executed in parallel, rather than in series, as they would be in Ethereum’s original, pre-upgrade architecture.
For users who frequently trade or perform high-volume transactions, the potential to alter how they use the platform with incentive gas fee reductions should lead to more activity and more volume on the platform.
Indeed, merely one month post-initiation of Hooked pools, Uniswap has already recorded remarkable outcomes. These new pools have produced in excess of $190 million in trading volume—clearly demonstrating a demand for liquidity that is both more flexible and cost-effective. Projects like Flaunch and Bunni v2 have already begun to utilize these Hooked pools in ways that pioneer new models altogether. And that, folks, is a sign of just how potentially disruptive Uniswap v4 could be.
Uniswap’s v4: More Than Just an Upgrade
The v4 upgrade of Uniswap represents a profound change in the decentralized exchange arena. The automated market maker (AMM), used primarily for token swaps, has now taken on a life of its own: it’s become a liquidity engine, offering a programmable and highly customizable experience. I don’t even know where to begin with this, since there really is an ocean of potential out there; suffice to say, if you’re a developer working in DeFi, LP, or trader—there is much to love about Uniswap v4.
The shift to programmable liquidity also means Uniswap can be a top innovator in DeFi. And as the DeFi ecosystem keeps changing, platforms that let developers and users have even more control over how they interact with liquidity are the platforms that will succeed. The introduction in Uniswap v4 of Hooks and the Singleton model is a big step in this direction, keeping Uniswap very much in the DeFi game.
Uniswap v4’s influence could extend much further. It lets users make custom liquidity pools and strategies, which gives them power not just over their own funds but also over the kind of decentralized financial products and services that can reach a broad user base. What’s truly exciting is that we can now also expect a surge of new use cases built on this framework, as an ecosystem of developers extends the Uniswap construct and ratchets up the creative voltage that makes it a mainstay of DeFi.
