This period will depend on the implementation of Ethereum’s Dencun hard fork, which is scheduled to take place in March. The V4 upgrade follows a comprehensive security audit of the protocols, starting with Dencun.
Uniswap is the most widely used automated market maker. It is a decentralized exchange that uses liquidity pools to facilitate trading between tokens, rather than relying on a traditional order book where buyers and sellers directly match orders.
Launched in 2018, Uniswap has gone through several iterations, with Uniswap V3 being the current version introduced in May 2021. The main feature of V3 is that it supports “concentrated liquidity”. That is, it allows liquidity providers to choose a specific price range within which their capital operates. Earn higher commissions.
The V4 draft code indicates that Uniswap is moving towards a more modular structure, primarily through the integration of “hooks”. These hooks are smart contracts that facilitate further customization in Uniswap’s liquidity pools using methods such as dynamic fees, on-chain limit orders, and custom on-chain oracles.
The V4 release also introduces a “flash accounting” system that offers lower fees to liquidity providers. This mechanism relies on “ephemeral storage”, which will be enabled by the proposed EIP-1153 change to the Ethereum protocol, which is scheduled to be incorporated in the upcoming Dencun upgrade.
