Bridge Contracts for Cross-Chain Asset Transfers

A decentralized bridge implementation that enables secure cross-chain transfers between Base Sepolia and Holesky networks.

Overview

This project implements a bridge contract system allowing asset transfers between:

• Base Sepolia Chain
• Holesky Chain (Ethereum testnet)

Technical Stack

• Hardhat Development Environment
• TypeScript
• Hardhat Ignition for deployment management
• Environment configuration via dotenv
• Testing framework with Chai assertions

Key Features

• Secure cross-chain asset transfers
• Owner-controlled bridge deployment
• Automated testing suite
• Configurable deployment parameters

Setup

1. Install dependencies:

npm install

2. Configure environment variables: Create a .env file with:

INFURA_API_KEY=your_infura_key
PRIVATE_KEY=your_private_key
ETHERSCAN_KEY=your_etherscan_key
BASESCAN_KEY=your_basescan_key

Testing

Run tests:

npx hardhat test

Deployment

1. Deploy the bridge contract:

npx hardhat run scripts/deploy.ts --network <network>

2. Verify the contract on Etherscan:

npx hardhat verify --network <network> <contract_address>

Security

• Owner-controlled deployment
• Comprehensive test coverage
• Network-specific configurations

Networks

• Base Sepolia: For Base testnet operations
• Holesky: For Ethereum testnet operations
