INK [Ink Finance] Token

FeatherInk.addLiquidity(uint256,uint256) (#984-996) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#988-995)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract creator or owner is blacklisted for past scams

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

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.

Combination 2: Unchecked transfer + 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.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Contract ownership is not renounced (belongs to a wallet)

FeatherInk.slitherConstructorVariables() (#618-1101) uses literals with too many digits:
- _tTotal = 5000000000000 * 10 ** 18 (#630)
Use: Ether suffix, Time suffix, or The scientific notation
