Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
Different versions of Solidity is used:
- Version used: ['>=0.4.22<0.9.0', '^0.8.0']
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#3)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/IERC20.sol#3)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#3)
- ^0.8.0 (@openzeppelin/contracts/utils/Context.sol#3)
- >=0.4.22<0.9.0 (contracts/GoldDust.sol#3)
Use one Solidity version.

Context._msgData() (@openzeppelin/contracts/utils/Context.sol#20-22) is never used and should be removed
ERC20._burn(address,uint256) (@openzeppelin/contracts/token/ERC20/ERC20.sol#274-289) is never used and should be removed
Remove unused functions.

Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#3) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/IERC20.sol#3) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#3) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/utils/Context.sol#3) allows old versions
Pragma version>=0.4.22<0.9.0 (contracts/GoldDust.sol#3) is too complex
solc-0.8.9 is not recommended for deployment
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.

GoldDust.constructor() (contracts/GoldDust.sol#9-11) uses literals with too many digits:
- _mint(msg.sender,1000000000 * 10 ** 18) (contracts/GoldDust.sol#10)
Use: Ether suffix, Time suffix, or The scientific notation
