CCTP Token Transfer Demo

This is a demo application for making your already deployed token cross-chain using Socket and CCTP. The application allows users to:

1. Select the source chain where their token is deployed
2. Enter their token address
3. Deploy token contracts and vault across multiple chains
4. Transfer tokens between different chains

Supported Chains

• Arbitrum Sepolia
• Optimism Sepolia
• Base Sepolia

Prerequisites

• Node.js 18.x or later
• MetaMask wallet
• Access to the supported testnet chains
