Uniswap V3 is the largest exchange, creating over 1.5 trillion in trading volume. Uniswap has always been a leader in this field.
Innovative Features
Triggers (hooks): Can trigger certain actions at certain times, where donate is a new feature, traders can choose one asset as a fee, previously there were two.
Singleton mode: In V3, each pool is a contract, and each liquidity is an NFT, while in V4, they are merged into one contract.
Flash accounting: For a single swap, even if it crosses multiple pools, only the amount of the swap is calculated, and the swap is completed in one transaction.
In the example on the left, eth is swapped for dai, a total of 4 contracts are called, while the new version only needs to be called once, greatly saving gas fees.
50% eth->eth/usdc->usdc->usdc/dai->dai
50% eth->eth/usdt->usdt->usdt/dai->dai
