Solana NFT and Token Creation Guide

This guide provides step-by-step instructions for creating Solana NFTs and tokens using Metaplex's Candy Machine, and SPL tokens.

Prerequisites

• NodeJs: Version 16 or higher
• Install Solana CLI: If you haven't already, follow the Solana CLI Installation Guide to install the Solana Command Line Interface (CLI).
• Set up Phantom wallet: Download and create a new wallet or use an existing one. You'll need this wallet to interact with Solana and perform the tasks below.
• Sugar CLI: Legacy Version, V1.x

Generate a Solana Keypair

• Open your terminal.
• Run the following command to generate a new Solana keypair:

  mkdir spl-token-nft-mint
  cd spl-token-nft-mint
  solana-keygen new --outfile wallet.json
  

• This will create a new keypair and store it in a wallet.json file.
• Also airdrop 1 SOL to the account:

  solana airdrop 1 <wallet-public-key> --url https://api.devnet.solana.com
  

• Import the wallet's private key to Phantom wallet.

Create and Mint a New SPL Token (MetaToken)

Open the mint-spl-tokens folder:

cd mint-spl-tokens

Install dependencies:

yarn
`or`
npm install

Add your Solana Devnet QuickNode RPC Endpoint:

const umi = createUmi('REPLACE_WITH_SOLANA_RPC');

(Optional) Add the IPFS URL of your token's image metadata:

const metadata = {
    name: "MetaToken",
    symbol: "MTK",
    uri: "IPFS_URL_OF_METADATA",
};

Run the mint script:

ts-node mint.ts

Upon successful execution you should see an output like this:
Successfully minted 1 million tokens ( 3G2wpf585WGES9mkuQuonoP2wr4RHFboAzxA5AfMf51f )

Create, Deploy, and Mint your NFT with sugar CLI

Navigate to the spl-token-nft-mint directory:

cd ../

Confirm your sugar CLI version:

sugar --version
`or`
./sugar --version

Ensure your sugar version is the legacy version 1.x or reinstall.

Validate, Upload, Deploy, and Verify your NFT assets

sugar launch

sugar launch starts a chain of commands:

• sugar validate
• sugar upload
• sugar deploy
• sugar verify

Copy your Candy machine ID after sugar deploy
A config.json file is generated after sugar launch is done running. This file contains the details of how the NFTs are to be minted.

Use the Created SPL Token to Pay for the Mint

To use our SPL tokens to mint, we specify the SPL token address in the config.json file, then run sugar deploy to modify the NFT.

Connect the NFT Contract to Metaplex's Candy Machine UI

Navigate to the candy-machine-ui directory

cd ../
git clone https://github.com/metaplex-foundation/candy-machine-ui
cd candy-machine-ui

Rename .env.example to .env and fill in the necessary details

REACT_APP_CANDY_MACHINE_ID=<YOUR_CANDY_MACHINE_ID>
REACT_APP_SOLANA_NETWORK=devnet
REACT_APP_SOLANA_RPC_HOST=<YOUR_SOLANA_RPC_ENDPOINT>
SKIP_PREFLIGHT_CHECK=false

Install dependencies

yarn
`or`
npm install

Strat the minting app

yarn start

PS: If you get an error running yarn start, open the package.json file and set "start": "SET NODE_OPTIONS=--openssl-legacy-provider && craco start"

Thanks
