--- ### ITSwapPool.sol ITSwapPool.sol is up next in our climb towards more complex code bases to review in Thunder Loan. ```solidity // SPDX-License-Identifier: AGPL-3.0-only pragma solidity 0.8.20; interface ITSwapPool { function getPriceOfOnePoolTokenInWeth() external view returns (uint256); } ``` This looks like another simple interface with a TSwap contract. We can assure it's being executed correctly by comparing things like parameters required and return values types with the underlying function. Have a peek at this function within TSwapPool quickly. ```js function getPriceOfOnePoolTokenInWeth() external view returns (uint256) { return getOutputAmountBasedOnInput( 1e18, i_poolToken.balanceOf(address(this)), i_wethToken.balanceOf(address(this)) ); } ``` We can see this takes no parameters and returns a uint256 as described by our interface. Things look great here. One question we may have for the Thunder Loan team: ```js // @Audit-Question: Why are we only using the price of a pool token in weth? ``` The limited nature of tokens being used may raise questions pertaining to the protocol's intent, we should always ask when unsure! ### Wrap Up Wow, another quick one down, we're flying through these quick wins. Thanks Tincho Method!
