In this guide, we’ll walk through minting a simple NFT on the Avalanche Fuji Testnet using Remix IDE and Core Wallet (Core.app). No coding experience? No problem! I’ll explain each step in simple terms.

What is an NFT?

An NFT (Non-Fungible Token) is a unique digital asset stored on a blockchain. Unlike regular cryptocurrencies like Bitcoin or AVAX, NFTs represent ownership of a unique item, such as digital art, music, or collectibles.

What is Avalanche and Why Use It?

Avalanche is a fast and low-cost blockchain. We are using its Fuji Testnet, which allows us to test things without using real money.

We’ll use:

Remix IDE (a website where we write and deploy smart contracts).
Core Wallet (Avalanche’s official wallet to interact with the blockchain).Step 1: Set Up Core Wallet

1.1 Download and Install Core Wallet
- Go to https://core.app/ and download Core Wallet for your device.
- Install and create a new wallet (or restore an existing one).

1.2 Switch to Avalanche Fuji Testnet

Open Core Wallet.
Click Settings → Network → Switch to Avalanche Fuji Testnet.
This allows us to use test AVAX instead of real money.

1.3 Get Test AVAX (Free!)

We need test AVAX to pay for transactions.

Visit the Avalanche Fuji Faucet.
Paste your Core Wallet address and click Request AVAX.
You’ll receive free test AVAX in your wallet.

Step 2: Write the NFT Smart Contract

A smart contract is a small program that runs on the blockchain. We’ll use it to create and store our NFT.

2.1 Open Remix IDE

Go to https://remix.ethereum.org/.
This is a web-based tool where we can write and deploy smart contracts.

2.2 Create a New File

On the left sidebar, click + to create a new file.
Name it MyNFT.sol.

After that, click on compile and run

- Under the deploy and run transactions. Click wallet connect.
  - Once you’ve connected your wallet,. Click on deploy.
    
    That’s all in creating your first NFT.

Mint an NFT

Now that the contract is live, we can mint an NFT (create a digital collectible).

3.1 Open Your Deployed Contract in Remix
- In Remix, scroll down to Deployed Contracts.
- Click on your contract name (MyNFT at 0x...).

3.2 Mint Your NFT

Find the "createNFT" function.
In the _to field, enter your Core Wallet address.
In the tokenURI field, enter a link to an image or metadata (example: "https://example.com/my-nft.json").
Click Transact and approve the transaction in Core Wallet.

🎉 Your NFT is now minted!

4: Verify Your NFT on Avalanche Blockchain

You can check your NFT on the Avalanche C-Chain Explorer.

4.1 Search for Your Wallet Address

Go to https://cchain.explorer.avax-test.network/.
Paste your Core Wallet address in the search bar.
Look under Transactions for the NFT minting transaction.

4.2 View Your NFT

Some blockchain explorers may not display NFTs, but you can verify it using a tool like SnowTrace.
