Code:

Olympicdogeking.addLiquidity(uint256,uint256) (#735-745) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,teamWallteAddress,block.timestamp) (#737-744)
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.

Contract ticker (Olympic dogeking) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Contract ticker (Olympic dogeking) has length of 16 chars.
Not a direct threat, but may indicate unreliable intentions of developer.

Olympicdogeking.addLiquidity(uint256,uint256) (#735-745) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,teamWallteAddress,block.timestamp) (#737-744)
