Uniswap Labs said that version 4 deployment will begin to be gradually rolled out this week for developers to test hooks and integrations on the chain, and all contracts are expected to be fully deployed and launched next week.
“We expect all contracts to be deployed for a full launch next week,” Uniswap Labs said Tuesday on X.
Uniswap v4 inherits the capital efficiency gains of v3 while introducing various architectural improvements.
One of the most notable changes in v4 includes implementing a “singleton” liquidity architecture — helping consolidate liquidity via a single smart contract. This could result in faster transactions, lower gas fees and a smoother user experience.
Another feature is the protocol's increased modularity, most notably the introduction of “hooks.” Hooks are contracts that can be built atop Uniswap, enabling developers to customize functions in liquidity pools further.
It will also introduce a “flash accounting” system for the platform. Instead of transferring assets in and out of pools at the end of every swap in v3, this system transfers only on net balances, which, according to the team, would result in significant gas savings in Uniswap v4.
Uniswap developers had planned to roll out Uniswap v4 in 2024, but it was delayed due to multiple code audits and security competitions.
