CrossFlow is a cross-chain decentralized exchange (DEX) powered by Chainlink's Cross-Chain Interoperability Protocol (CCIP). It allows users to seamlessly swap tokens across multiple blockchain networks, providing a user-friendly and secure platform for decentralized finance (DeFi) transactions.
CrossFlow facilitates seamless cross-chain token swaps, allowing users to move assets across different blockchain networks. By leveraging Chainlink's CCIP for cross-chain communication and Chainlink Price Feeds for accurate pricing, CrossFlow ensures secure and efficient transactions.
- Cross-Chain Swaps: Swap tokens across different blockchain networks.
- Chainlink Integration: Utilizes Chainlink CCIP for cross-chain transfers and Price Feeds for accurate market pricing.
- User-Friendly UI: Built with Next.js and Tailwind CSS for a responsive and intuitive interface.
- Secure Wallet Connection: Integrated with WalletConnect for secure wallet interactions.
- Seamless Blockchain Interaction: Powered by Ethers.js for smooth communication with the Ethereum network.
CrossFlow's architecture consists of two main smart contracts: CrossFlow and CrossDex.
- CrossFlow Contract: Handles cross-chain interactions using Chainlink CCIP.
- CrossDex Contract: Manages token swaps, particularly for tokens not natively supported by CCIP. Integrates Chainlink Price Feeds for accurate pricing.
- Frontend: Next.js, Tailwind CSS
- Blockchain Interaction: Ethers.js
- Wallet Integration: WalletConnect
- Smart Contracts: Solidity, Hardhat
- Cross-Chain Protocol: Chainlink CCIP
- Pricing Data: Chainlink Price Feeds
To get started with CrossFlow, follow these steps:
- Node.js (v14 or higher)
- Yarn or npm
- Hardhat
- Clone the repository:
git clone https://github.com/PhantomOz/crossflow.git
- Navigate to the project directory:
cd crossflow - Install dependencies:
npm install
Create a .env.local file in the root directory and add the following environment variables:
WALLETCONNECT_PROJECT_ID=your_walletconnect_project_id
Replace your_walletconnect_project_id with your actual project IDs.
To start the frontend application:
npm run devThe application will be available at http://localhost:3000.
- Compile the smart contracts:
npx hardhat compile
- Deploy the contracts to a local or test network:
npx hardhat ignition deploy ignition/modules/CrossFlow.ts --network <network_name> --verify
Replace <network_name> with your desired network (e.g., localhost, sepolia, baseSepolia).
