ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (#1731-1753) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (#1733)
CoinaryToken.mint(address,uint256) (#1885-1896) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp >= nextMintingDate,CoinaryToken: You must wait 24 hours until the next minting) (#1892)
Avoid relying on block.timestamp.
