• 2 owner privileges.

3.1. Owner Privileges

Severity: owner privileges

Description

Contract owner allow himself to:

1. Upgrade the token contract and implement any logic in the new contract:

    function setTokenAddress(IERC20 token) public onlyOwner returns(bool){
        LCXToken = token;
        return true;
    }      

2. Revoke the vesting, and take users tokens for himself even if the tokens were bought by the users using ETH or a different asset.

    function revoke(address account) public onlyOwner {
        VestedToken storage vested = vestedUser[account];
        require(!vested.revoked);
        uint256 balance = vested.totalToken;
        uint256 vestedAmount = _vestedAmount(account);
        uint256 refund = balance.sub(vestedAmount);
        require(refund > 0);
        vested.revoked = true;
        vested.totalToken = vestedAmount;
        LCXToken.safeTransfer(owner(), refund);
        emit VestingRevoked(account);
    }

4. Conclusion

The audited contract is safe if the owner is trustworthy otherwise the users should be aware of the risks.
