Compilation

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

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

Copy
npm hardhat compile

The hardhat tool automatically selects Solidity version 0.8.7 as specified within the hardhat.config.js file.

The project contains discrepancies with regards to the Solidity version used containing open-ended declarations (^0.8.7) rather than locked ones (=0.8.7). We advise the WallFair team to lock the pragma statements to 0.8.7, 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.

An additional configuration for live deployments exists labelled as hardhat-deploy.config.js that allows deployment of the contract system to one of the live chains.
