UnityVenturesToken.addLiquidity(uint256,uint256) (dist/UnityVenturesToken.sol#1315-1328) sends eth to arbitrary user
Dangerous calls:
- uvSwapRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,operator(),block.timestamp) (dist/UnityVenturesToken.sol#1320-1327)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

UnityVenturesToken._writeCheckpoint(address,uint32,uint256,uint256) (dist/UnityVenturesToken.sol#1630-1648) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (dist/UnityVenturesToken.sol#1640)
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.
UnityVenturesToken._transfer(address,address,uint256) (dist/UnityVenturesToken.sol#1231-1260) performs a multiplication on the result of a division:
-taxAmount = amount.mul(transferTaxRate).div(10000) (dist/UnityVenturesToken.sol#1247)
-burnAmount = taxAmount.mul(burnRate).div(100) (dist/UnityVenturesToken.sol#1248)
Consider ordering multiplication before division.

UnityVenturesToken.addLiquidity(uint256,uint256) (dist/UnityVenturesToken.sol#1315-1328) ignores return value by uvSwapRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,operator(),block.timestamp) (dist/UnityVenturesToken.sol#1320-1327)
Ensure that all the return values of the function calls are used.

Rename the local variables that shadow another component.

UnityVenturesToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (dist/UnityVenturesToken.sol#1496-1537) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,UV::delegateBySig: signature expired) (dist/UnityVenturesToken.sol#1535)
Avoid relying on block.timestamp.

UnityVenturesToken.getChainId() (dist/UnityVenturesToken.sol#1655-1659) uses assembly

Remove the equality to the boolean constant.

Remove unused functions.
Additional information: link
Pragma version>=0.4.0 (dist/UnityVenturesToken.sol#821) allows old versions
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

transferOperator(address) should be declared external:
- UnityVenturesToken.transferOperator(address) (dist/UnityVenturesToken.sol#1425-1429)
Use the external attribute for functions never called from the contract.
