UNI is a decentralized exchange that recently announced its V4 development plan. However, the launch of V4 will have to wait for the completion of the Ethereum Cancun upgrade. If there are no security issues or delays in the upgrade and audit, V4 may be launched later this year. #UNI
Currently, UNI's V3 version is limited by the capacity of the Ethereum network, resulting in high fees and slow transaction times. But with the adoption of Ethereum 2.0 and the launch of layer 2 solutions, V4 is expected to be able to handle a larger number of transactions without encountering these problems.
V4 introduces many new features, including a "flash accounting" system to reduce fees for liquidity providers, and expanding the token swap capabilities of DEX by introducing "pegging" and custom liquidity pools. The goal of the new features is to implement features such as on-chain limit orders and dynamic fees. In addition, the cost of creating a pool on V4 will also be cut by 99% because all pools are located in a single contract.
