Using uniswap, I want to check the amount of token0 and token1 deposited by user. For instance, user created pair Token0/Token1 in Uniswap. First, user input amount of Token0 and Token1. When start trading and used user's token, the remaining amount would be changed. (I think it seems that the remaining amount is called reserve.
If someone knows about this, please help me. Thank you
