Compilation

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

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

Copy
npx hardhat compile

The hardhat tool automatically selects Solidity version 0.8.22 based on the version specified within the hardhat.config.ts file.

The project contains discrepancies with regards to the Solidity version used as the pragma statements of the contracts are open-ended (^0.8.0).

We advise them to be locked to 0.8.22 (=0.8.22), 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.

To note, the compiler version utilized makes use of the Shanghai target EVM and thus will introduce the PUSH0 opcode which is incompatible with certain Layer-2 chains.

We advise the Astrolab DAO team to evaluate whether the chains they wish to deploy their contracts to properly support the operation code when they intend to deploy so as to avoid any deployment failures and thus waste of resources.
