How are LP rewards calculated?

The returns would vary for investors who provided liquidity at different times due to different ETH/DAI prices.

Each Uniswap liquidity pool is a trading venue for a pair of ERC20 tokens . When a pool contract is created, its balances of each token are 0; in order for the pool to begin facilitating trades, someone must seed it with an initial deposit of each token.

Uniswap incentivizes users to add liquidity to trading pools by rewarding providers with the fees generated when other users trade with those pools . Market making, in general, is a complex activity.

Every time a trade is executed on Uniswap, liquidity providers (LPs) earn fees proportional to the amount of liquidity they have supplied. This fee is usually set at 0.3% but can be as low as 0.05% for stable assets, and as high as 1% for more exotic pairs .

UniSwap is a protocol that allows traders to swap Ethereum ERC20 tokens without using an order book . The swap rate is based on the demand for both tokens and the balances of the swapping pair. Traditional markets heavily rely on liquidity for their success.
