MEDIUM severity: The codebase contains a multitude of contracts and libraries, all of which are defined within the sa. The codebase contains a multitude of contracts and libraries, all of which are defined within the same file. This organizational approach hinders the ease of navigation, development, and auditing of the code. A best practice in software development is to separate each contract or library into its ow...
