Severity:
Use specific version of Solidity, instead of wide version.
Vulnerability Details
The smart contracts for One Shot project are using ^0.8.20 version, which means from 0.8.20 up to, but not including 0.9.0. However a future version of Solidity could be released that contains a bug, that can introduce a potential vulnerability in these contracts.
Impact
Allowing the use of later-on versions of Solidity, that haven't undergone extensive testing can leave the protocol open for exploits.

Recommendations
