Create SPL Tokens and NFTs on SOON Testnet

This guide demonstrates how to create Solana Program Library (SPL) tokens and Non-Fungible Tokens (NFTs) on the SOON testnet using the Metaplex Foundation's UMI framework and MPL Token Metadata program.

Prerequisites

• Node.js (v14 or higher)
• npm or yarn package manager
• Basic understanding of Solana, SPL tokens, and NFTs
• Pinata account and API keys (from Pinata.cloud)

Installation

Install the required dependencies:

pnpm i

Setup

1. Clone this repository or create a new directory for your project
2. Make sure you have a funded wallet on SOON testnet
3. Obtain your Pinata API keys from the Pinata.cloud website and add them to a .env file in the project directory:

   PINATA_JWT=your_pinata_jwt_here
   PINATA_GATEWAY_TOKEN=your_pinata_gateway_token_here
   

Configuration

The code uses the following main components:

• UMI instance connected to SOON testnet
• Payer keypair for signing transactions
• Mint signer for the new token and NFT

Important Variables

• umi: UMI instance connected to SOON testnet RPC endpoint
• payerSecretKey: Your wallet's secret key (Keep this secure!)
• mint: Newly generated token mint address
• NFTsigner: Signer for creating the new NFT

SPL Token Parameters

The SPL token is created with the following parameters:

• Name: "BONK"
• Decimals: 7
• Seller Fee: 5.5%
• URI: Points to metadata stored on Pinata

NFT Parameters

The NFT is created with the following parameters:

• Name: "My NFT"
• Description: "This is an NFT on SOON"
• Image: Hosted on Pinata
• External URL: "https://x.com/soon-svm"
• Attributes: "trait1" and "trait2"

Usage

1. Replace the payerSecretKey with your own wallet's secret key
2. Modify the token and NFT parameters in the main() function as needed:
   • SPL Token: name, uri, sellerFeeBasisPoints, decimals
   • NFT: name, description, image, external_url, attributes
3. Run the script:

pnpm nft

Output

The script will output:

• Payer's SOL balance
• Payer's public key
• New token's mint address
• New NFT's mint address
• Transaction hashes

Security Considerations

• Never commit your secret key to version control
• Store sensitive information in environment variables
• Ensure your wallet has sufficient SOL for transaction fees

Network Selection

The code is configured for SOON testnet. To use different networks:

• Devnet
• Testnet
