TestContract

The TestContract is designed to interact with Caerus's storage slots. It allows users to set and get a storage variable (slot0) and offers a method to fetch the storage value based on a historical block number.

Methods:

1. setSlot0(uint256 _slot0)

• Sets the value of slot0 to the provided integer _slot0.

2. getSlot0()

• Returns the current value stored in slot0.

3. getSlot0Caerus(uint256 blockNumber)

• Fetches the value of slot0 at a specified block number.
• Throws an error if the provided block number is greater than or equal to the current block number.

Prerequisites

• Node.js v12+ LTS and npm (comes with Node)
• Hardhat

Installation

Clone the repository:

git clone https://github.com/Caerus-Chain/test-contract

Navigate to the project folder:

cd test-contract

Install dependencies:

npm install

Set Up Configuration:

1. Review the .example.env file.
2. Create a .env file based on the example and adjust the values as needed.

For Linux or macOS:

cp .example.env .env

For Windows:

copy .example.env .env

Compilation

Compile the smart contracts using Hardhat:

npx hardhat compile

Quick Start Guide

1. Testing

Run the following command to execute the contract tests. Make sure you've written the tests in your Hardhat project's test directory.

npx hardhat test

2. Deployment:

Run the following command to compile the contracts using the Solidity compiler and deploy the TestContract to your Caerus network.

npx hardhat run scripts/deploy.js --network caerus

3. Interaction:

Before running the script, make sure to replace the placeholder contract address in test.js with your deployed contract address.

npx hardhat run scripts/test.js --network caerus

• Use the setSlot0 function to change the value of slot0.
• Use the getSlot0 and getSlot0Caerus functions to fetch the value stored in slot0.
