ZINAX Token

ZINAXDAO.recoverBEP20(IBEP20,address) (#1124-1129) ignores return value by token.transfer(recipient,amount) (#1127)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Different versions of Solidity is used:
- Version used: ['0.6.12', '>=0.6.0<0.8.0', '>=0.6.2<0.8.0']
- >=0.6.0<0.8.0 (#20)
- >=0.6.2<0.8.0 (#237)
- 0.6.12 (#429)
Use one Solidity version.

Additional information: link

Pragma version>=0.6.0<0.8.0 (#20) is too complex
Pragma version>=0.6.2<0.8.0 (#237) 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.
