Different versions of Solidity are used:
- Version used: ['0.8.12', '^0.8.0', '^0.8.1']
- ^0.8.0 (@openzeppelin/contracts/access/Ownable.sol#4)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#4)
- ^0.8.0 (@openzeppelin/contracts/token/ERC20/IERC20.sol#4)

- ^0.8.1 (@openzeppelin/contracts/utils/Address.sol#4)
- ^0.8.0 (@openzeppelin/contracts/utils/Context.sol#4)
- 0.8.12 (contracts/token/MetaCloud.sol#2)
Use one Solidity version.
Additional information: link
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/IERC20.sol#4) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/utils/SafeERC20.sol#4) allows old versions
Pragma version0.8.12 (contracts/token/MetaCloud.sol#2) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#4) allows old versions
solc-0.8.12 is not recommended for deployment
Pragma version^0.8.0 (@openzeppelin/contracts/token/ERC20/ERC20.sol#4) allows old versions
Pragma version^0.8.1 (@openzeppelin/contracts/utils/Address.sol#4) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/access/Ownable.sol#4) allows old versions
Pragma version^0.8.0 (@openzeppelin/contracts/utils/Context.sol#4) 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.
