Please complete the report problem below:

Problem 1

Provide your profitable path, the amountIn, amountOut value for each swap, and your final reward (your tokenB balance).

Solution

Problem 2

What is slippage in AMM, and how does Uniswap V2 address this issue? Please illustrate with a function as an example.

slippage is price change before swaping,we uniswap can set a minimum amount out

Problem 3

Please examine the mint function in the UniswapV2Pair contract. Upon initial liquidity minting, a minimum liquidity is subtracted. What is the rationale behind this design?

This ensures the total supply is always greater than zero, preventing division by zero errors.

Problem 4

Investigate the minting function in the UniswapV2Pair contract. When depositing tokens (not for the first time), liquidity can only be obtained using a specific formula. What is the intention behind this? maintain the pool 50/50

Solution

Problem 5

What is a sandwich attack, and how might it impact you when initiating a swap?

A bigger order placed before my smaller order, then moved the price against me, ending up receiving fewer tokens
