PENNY.byToken(bytes[],uint256[],address[],address[],uint256[],string[],bytes32) (#358-396) contains a tautology or contradiction:
- require(bool,string)(details[0] >= 0 && details[0] < 8,Invalid Type) (#369)

Pragma version0.8.10 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.10 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.
