🛠️ Upgradable Smart Contract with ERC1967 Proxy

📌 Overview

This project demonstrates how to deploy and upgrade a Solidity smart contract using the ERC1967 Proxy pattern. It includes:

• BasicContractV1: Initial contract version
• BasicContractV2: Upgraded contract version
• ERC1967 Proxy: Used for contract upgradability
• Foundry Tests: Ensures deployment and upgrade functionality

🚀 Installation & Setup

1️⃣ Clone the Repository

git clone https://github.com/Rahber-1/Upgradeable_Contracts_Project.git cd Ugradeable_Contracts_Project

2️⃣ Install Foundry

curl -L https://foundry.paradigm.xyz | bash
foundryup

3️⃣ Install Dependencies

forge install

4️⃣ Compile the Contracts

forge build

5️⃣ Run Tests

forge test -vv

📜 Smart Contract Explanation

1️⃣ BasicContractV1 (Initial Contract)

• Implements the core logic
• Uses OpenZeppelin’s OwnableUpgradeable
• Function: initialize() for initializing state

2️⃣ BasicContractV2 (Upgraded Version)

• Extends BasicContractV1
• Introduces additional functionality

3️⃣ ERC1967 Proxy

• Used to delegate calls to implementation contracts
• Enables upgradability without changing the contract address

📜 Deployment & Upgrade

Deploy V1 Contract

forge script script/DeployBasicContractV1.s.sol --rpc-url YOUR_RPC_URL --broadcast

Upgrade to V2

forge script script/DeployUpgrade.s.sol --rpc-url YOUR_RPC_URL --broadcast

🧪 Running Tests

Test Coverage Includes:
✔️ Deployment of V1 contract
✔️ Ensures correct contract version
✔️ Upgrade to V2 and validation

Run all tests:
forge test -vv
