🚀 Upgradeable Smart Contract System

A professional-grade implementation of upgradeable smart contracts using the UUPS (Universal Upgradeable Proxy Standard) pattern. This project showcases advanced Solidity development practices, comprehensive testing, and secure upgrade mechanisms.

🌟 Key Features

• UUPS Proxy Pattern Implementation: Leverages OpenZeppelin's battle-tested contracts for secure upgradeability
• Version Control: Seamless contract versioning with BoxV1 → BoxV2 upgrade path
• Comprehensive Testing: Full test coverage using Foundry's robust testing framework
• Professional Deployment Scripts: Automated deployment and upgrade processes
• Security-First Design: Implements critical security patterns and access controls

🏗️ Technical Architecture

Smart Contracts

• BoxV1.sol - Initial implementation with basic functionality
• BoxV2.sol - Enhanced implementation with additional features
• ERC1967Proxy - Industry-standard proxy contract from OpenZeppelin

Infrastructure

• Framework: Built with Foundry for modern Solidity development
• Testing: Advanced test suite with state management and upgrade verification
• Deployment: Automated scripts for both initial deployment and upgrades

🔒 Security Features

• Initialization protection using OpenZeppelin's Initializable
• Ownership management with OwnableUpgradeable
• UUPS upgrade pattern with access controls
• Constructor safeguards for implementation contracts

Quick Start

git clone https://github.com/SquilliamX/Foundry-Upgradeable-UUPS.git
cd Foundry-Upgradeable-UUPS
forge build
forge install

🧪 Testing

forge test

The test suite includes:

• Proxy deployment verification
• Implementation upgrade validation
• State persistence checks
• Access control verification

📦 Deployment

The system uses a two-step deployment process:

1. Initial Deployment:

forge script script/DeployBox.s.sol

2. Upgrade Process:

forge script script/UpgradeBox.s.sol

🔍 Technical Deep Dive

Upgrade Pattern

The system implements the UUPS pattern, which:

• Maintains a single proxy entry point
• Preserves contract state during upgrades
• Reduces gas costs compared to alternative patterns
• Provides enhanced security through implementation-side upgrade logic

State Management

• Utilizes OpenZeppelin's upgradeable contracts
• Implements proper initialization patterns
• Maintains state consistency across upgrades

🛠️ Development Stack

• Solidity ^0.8.19
• OpenZeppelin Contracts (Upgradeable)
• Foundry Development Framework
• DevOps Tools for Deployment Management
