Assignment 8: Create a cNFT Collection

Overview

This assignment involves creating a cNFT (compressed NFT) collection and airdropping it to other fellows. The application will use the Solana blockchain to mint and distribute the cNFTs.

Tech Stack

• TypeScript: For writing the application code
• Solana Web3.js: For interacting with the Solana blockchain
• Express: For building the backend API
• dotenv: For managing environment variables
• @metaplex-foundation/umi: For handling NFT creation and transactions
• @metaplex-foundation/mpl-bubblegum: For managing Merkle Trees and compressed NFTs
• @metaplex-foundation/mpl-token-metadata: For handling token metadata
• @metaplex-foundation/umi-bundle-defaults: For default Umi bundle configurations
• @metaplex-foundation/umi-web3js-adapters: For adapting Umi to Web3.js
• @solana/actions: For Solana blockchain actions
• bs58: For Base58 encoding/decoding

Project Structure

The main components of the project include:

• index.ts: Entry point of the application
• utils.ts: Utility functions for Solana and Umi integration
• Merkle-Tree.ts: Functions for creating and managing Merkle Trees
• cNFT.ts: Functions for minting individual cNFTs
• cNFTCollection.ts: Functions for minting and managing cNFT collections

How to Use

1. Clone the repository
2. Install dependencies: npm install
3. Set up your environment variables in a .env file based on the .env.example
4. Start the development server: npm run dev

Key Components

• Minting Handler: Mints cNFTs with specified metadata
• Airdrop Handler: Airdrops the minted cNFTs to specified addresses
• Merkle Tree Handler: Creates and manages Merkle Trees for compressed NFTs

Solana Integration

The application uses Solana for minting and airdropping cNFTs. Key steps include:

1. Setting up Solana configuration and environment variables
2. Creating and managing Merkle Trees
3. Minting cNFTs with metadata
4. Airdropping cNFTs to other fellows
