TREE [TreeDefi] Token

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

TreeToken._writeCheckpoint(address,uint32,uint256,uint256) (TreeDefiToken.sol#306-324) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (TreeDefiToken.sol#316)
Don't use strict equality to determine if an account has enough Ether or tokens.

TreeToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (TreeDefiToken.sol#172-213) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,TREE::delegateBySig: signature expired) (TreeDefiToken.sol#211)
Avoid relying on block.timestamp.

Pragma version>=0.4.0 (BEP20.sol#3) allows old versions
Pragma version>=0.6.0<0.8.0 (Context.sol#3) is too complex
Pragma version>=0.6.4 (IBEP20.sol#3) allows old versions
Pragma version>=0.6.0<0.8.0 (Ownable.sol#3) is too complex
Pragma version>=0.6.0<0.8.0 (SafeMath.sol#3) is too complex
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.
