Compilation

The project utilizes hardhat as its development pipeline tool, containing an array of scripts coded in JavaScript.

To compile the project, the compile command needs to be issued via the hardhat CLI tool invoked via npx:

Copy
npx hardhat compile

The hardhat tool automatically selects Solidity version 0.8.4 based on the version specified within the hardhat.config.js file.

The project contains discrepancies with regards to the Solidity version used only within its dependencies which can be safely ignored. The Polytrade Finance team has locked the pragma statements to 0.8.4, the same version utilized for our static analysis as well as optimizational review of the codebase.

During compilation with the hardhat pipeline, no errors were identified that relate to the syntax or bytecode size of the contracts of the project.

We should note, however, that the hardhat.config.js file specifies the optimizer within its compilers settings with a runs value of 1000000 which is significantly high. Generally, the optimizer works better the lower the value is and not the other way around that most people think. As a result, we advise a value of 400 or 200 to be utilized.
