Unlocked Compiler Versions - Floating pragmas

[sangier]

The contracts have unlocked compiler versions.

An unlocked compiler version allows the user to compile it at or above a particular version. This can lead to differences in the generated bytecodes between the compilations that can be different to what was originally tested. Additionally it can led to ambiguity when debugging specific compilers related bug that may occur.

• Decide which solidity version we wanna use.
• Lock the compiler version e.g. pragma solidity 0.8.25;

Just noted that the new solidity version 0.8.26 allows custom error support inside require statement. IMO we should use this type of error management instead of revert
