The variable "amountOutMin" is used to determine the minimal amount of tokens as the result of the swap.

The scope of the review treats the calculation of "amountOutMin" as a black box and assumes its correct calculation.

The contract is serving as the underlying entity to interact with one or more third party protocols. The scope of the audit treats third party entities as black boxes and assumes their functional correctness. However, in the real world, third parties can be compromised and this may lead to lost or stolen assets. In addition, upgrades of third parties can possibly create severe impacts, such as increasing fees of third parties, migrating to new LP pools, etc. ```solidity=17 IUniswapV2Router02 public router; ``` - The contract `PaalXSwapContract` interacts with third party contract with `IUniswapV2Router02` interface via `router`.
