--- ### TSwapPool Final Functions The outstanding functions to check in TSwapPool are getters it seems, let's give them a review. ### totalLiquidityTokenSupply ```js /// @notice a more verbose way of getting the total supply of liquidity tokens // @ Audit-Informational - should be marked external function totalLiquidityTokenSupply() public view returns (uint256) { return totalSupply(); } ``` Looks _mostly_ good, but we should note that getters like these can be marked `external` to save gas. ### getPoolToken, getWeth, getMinimumWethDepositAmount ```js function getPoolToken() external view returns (address) { return address(i_poolToken); } function getWeth() external view returns (address) { return address(i_wethToken); } function getMinimumWethDepositAmount() external pure returns (uint256) { return MINIMUM_WETH_LIQUIDITY; } ``` These three functions all look great, with proper visibilities set. Now our final two functions: ```js function getPriceOfOneWethInPoolTokens() external view returns (uint256) { return getOutputAmountBasedOnInput( 1e18, i_wethToken.balanceOf(address(this)), i_poolToken.balanceOf(address(this)) ); } function getPriceOfOnePoolTokenInWeth() external view returns (uint256) { return getOutputAmountBasedOnInput( 1e18, i_poolToken.balanceOf(address(this)), i_wethToken.balanceOf(address(this)) ); } ``` These are returning the price of 1 weth in PoolTokens and 1 PoolToken in weth respectively. At face value, I'll tell you that these functions look fine. Their math checks out, simple enough. Though in a later section - Thunder Load - you'll learn that functions like these can be deceiving 😉 Having concluded our manual review, we can jump into the reporting phase in the next lesson - let's go!
