Tree Defi is a leveraged-yield farming protocol built on the Binance Smart Chain. It allows yield farmers to earn higher return by opening leveraged positions. Moreover, one third of the deposit fees on our platform will be used to plant trees in real life. Our donations will have proof of purchase and will by trackable by users through the blockchain.

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.
