Uniswap Labs, the event workforce behind crucial decentralized alternate (DEX) on the Ethereum community, introduced that the most recent model of its protocol might be launched subsequent week, between January 27 and February 2.
A publish on the corporate’s X social community reported that official implementations of the brand new model of the protocol start this week.
Model 4 (v4) deployments will start for builders to check the hooks and chain integrations.

The event workforce estimates that “all contracts might be deployed for a full launch subsequent week”, that’s, that the v4 protocol of the decentralized alternate might be accessible to the general public.
What’s new in Uniswap v4?
Uniswap v4 comes with quite a few updates that promise to enhance the performance and efficiency of the alternate platform. Among the many most notable options talked about in its whitepaper is a brand new liquidity mannequin, referred to as “singleton«, that retains all of the liquidity of the swimming pools in a single sensible contract.
Architecturally, all pool states and operations are managed by a single contract: PoolManager.sol. The singleton design presents vital fuel financial savings. For instance, making a pool is now a standing replace as a substitute of deploying a brand new contract. Swapping between a number of swimming pools not requires the switch of tokens to intermediate swimming pools.

One other replace to Uniswap v4 is the introduction of «hooks» customizable. These hooks have an effect on the performance of liquidity swimming pools and different improvement instruments, giving them extra flexibility. It can additionally permit builders to introduce so-called dynamic charges, that may enhance the effectivity of exchanges and the power to “adapt charges to altering market circumstances”
Builders can connect Solidity logic to the swap lifecycle by the hooks. The logic is executed earlier than and/or after vital operations, reminiscent of pool creation, liquidity addition and elimination, swapping, and donations. The hooks They’re deployed contracts and are referred to as by the Uniswap v4 PoolManager for permissionless execution.

One other implementation is the «flash accounting» or accounting flash. Any alternate or modification in liquidity generates stability and stability modifications within the Uniswap protocol. “With flash accounting, these stability modifications are effectively recorded in transient storage and offset in opposition to one another. This method permits customers to pay solely the ultimate stability change, with out the necessity to resolve intermediate stability modifications,” feedback the technical doc of the brand new model.
Lastly, Uniswap v4 will help native tokens with out the necessity for contain them or develop them within the passage from one chain to a different. For instance, from ether, the native token of the Ethereum community, to wrapped ether (WETH9).
How does Uniswap v4 enhance on the earlier one?
The introduction of model 4 of Uniswap will enhance the present model in a number of methods. The creation of liquidity swimming pools, the mechanism by which customers can alternate tokens with out permission, can be simpler within the newest model.
In one other sense, the introduction of accounting flash will permit additional configuration of the pool parameters. “As a result of accounting flash just isn’t current in model 3, it’s the duty of the mixing contract to hold out token transfers, after every particular person name, to every particular person group contract”, feedback Uniswap Labs evaluating each variations.
Lastly, Uniswap model 4 will cut back or get rid of the prices related to the motion of wrapping tokens. Uniswap will now host native tokens in liquidity swimming pools, which suggests fewer further steps throughout exchanges and liquidity choices, in addition to decrease transaction charges.
