CRSS [Crosswise V1] Token

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

CrssToken.addLiquidity(uint256,uint256) (contracts/CrssToken.sol#387-403) sends eth to arbitrary user
Dangerous calls:
- (liquidity) = crosswiseRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(this),block.timestamp) (contracts/CrssToken.sol#392-399)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

CrssToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/CrssToken.sol#612-630) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/CrssToken.sol#622)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.
