Pull Request Overview

Started by updating dependencies in the project:

• Removed all dependencies except for hardhat and dotenv from package.json.
• Executed npm prune and npm install.

Then, upgraded the dependencies and introduced a new development dependency:

• npm install --save-dev @nomicfoundation/hardhat-toolbox.

Major API Changes

• Obtained contract addresses using contractObject.target instead of contractObject.address.
• Changed contract deployment approach:
  • Used deployContract instead of getContractFactory.
  • Replaced .deployed() with waitForDeployment for deployment completion.
  • Updated helper functions usage: No longer need ethers.utils for functions like parseEther and formatEther.

Solidity Contract Compatibility

No necessary changes were required for the Solidity contract between versions "0.8.4" (the original compiler version in the repository) and "0.8.24".
