GIGA [Gigantmons] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

gigantmons.addLiquidity(uint256,uint256) (#1243-1258) sends eth to arbitrary user
Dangerous calls:
- pancakeswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,burnAdd,block.timestamp) (#1249-1256)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

gigantmons.addLiquidity(uint256,uint256) (#1243-1258) ignores return value by pancakeswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,burnAdd,block.timestamp) (#1249-1256)
Ensure that all the return values of the function calls are used.

gigantmons.setSwapAt(uint256) (#1133-1135) should emit an event for:
- swapAtAmount = swapAmount (#1134)
Emit an event for critical parameter changes.
