Key Highlights

Uniswap V2

• It uses a simple automated market maker (AMM) model that allows users to trade tokens without relying on order books.
• Uniswap V2 uses a constant product market maker algorithm, which means that the product of the number of tokens in each pool is always constant. This ensures that the price of the token is automatically adjusted based on the supply and demand of the token.
• Uniswap V2 has a 0.3% fee per transaction, where 0.25% is allocated to the liquidity provider, while the remaining 0.05% goes to the DEX treasury.
• Uniswap V2 has a fixed fee structure, which means that liquidity providers cannot customize fees for their pools.
• Uniswap V2 has no limit on the number of liquidity providers that can contribute to a pool, which can result in high slippage for larger trades.

Uniswap V3

• Uniswap V3 was launched in May 2021 and introduced several new features, including concentrated liquidity and multiple fee tiers.
• Uniswap V3 allows liquidity providers to concentrate their liquidity in specific price ranges, which can result in higher capital efficiency and lower slippage for traders.
• Uniswap V3 has three fee tiers (0.05%, 0.3%, and 1%), which liquidity providers can choose from based on their risk tolerance and expected returns.
• Uniswap V3 has a more complex AMM model that uses a range of prices instead of a fixed price. This allows Uniswap V3 to provide more granular price exposure and reduce the impact of impermanent loss.
• Uniswap V3 has a customizable fee structure, which means that liquidity providers can choose the fee tier that best suits their needs.
• Uniswap V3 has a limit on the number of liquidity providers that can contribute to a pool, which can result in lower slippage for larger trades.

This feature allows for more efficient capital utilization and provides finer control over market exposure.

Multiple Fee Tiers

Uniswap v3 introduces the concept of multiple fee tiers. Liquidity providers can select different fee levels for their positions, enabling them to optimize their earnings based on the perceived risk and demand for the tokens they provide liquidity for. This flexibility provides additional options for liquidity providers and promotes a more dynamic ecosystem.

Oracle-Based Price Feeds

To enhance the accuracy of pricing information, Uniswap v3 incorporates oracle-based price feeds. These price feeds help ensure that trades are executed at fair and reliable prices, reducing the impact of impermanent loss and enabling more informed decision-making for traders.

Choosing Between Uniswap v2 and Uniswap v3
