Avalanche is a blockchain smart contracts platform similar to Ethereum for developing and deploying smart contracts for NFT minting, dApp deployment, and other Web3-related workflows.
Read below to learn how to launch a generative NFT collection with IPFS and Avalanche.
To do this, navigate to . If you don’t have an account already, , then log in.
Select ‘Create Bucket’ in the top right corner to create a new bucket for your NFTs.
Bucket names must be unique across all Filebase users, be between 3 and 63 characters long, and can contain only lowercase characters, numbers, and dashes.
mkdir avalanche-drop && cd avalanche-drop
npm init -y
npx hardhat
When prompted, select the create empty project option during the Hardhat initialization process.
https://ipfs.filebase.io/ipfs/IPFS_CID
Replace IPFS_CID with your folder’s IPFS CID.
npm install @openzeppelin/contracts
contracts
, then create a new file in this directory called NFT.sol
.Open this new file in your IDE of choice, and paste in the following content:
metadata
.mkdir metadata
metadata-generator.js
.Open this file in your IDE and insert the following content:
This code will generate metadata for each of the files in our IPFS folder. Replace the following values:
“./Images”: The folder name and file path of your image folder that you uploaded to Filebase earlier.
Name: Name for each NFT
Description: Description for each NFT
IPFS_FOLDER_CID: Your Filebase IPFS folder CID.
metadata-generator.js
script with the command:node metadata-generator.js
Upload these files to Filebase using the same folder upload method used at the beginning of this tutorial. Copy the CID of this folder for use in the next step.
hardhat.config.js
file at the root of your project folder.Replace the existing content with the following:
Replace PRIVATE_KEY_FOR_FUJI with your cryptowallet’s private key. To export your private key from MetaMask, select your Account Details, then select ‘Export Private Key’.
In your project’s root directory, create a new file called scripts
:
mkdir scripts && cd scripts
deploy.js
.Open this file in your IDE of choice, then insert the following content:
Replace the METADATA_FOLDER_CID with the IPFS CID of your folder that contains the metadata files we generated earlier. Replace TOKEN_NAME and TOKEN_SYMBOL with your desired information.
npx hardhat compile
npx hardhat run --network avalancheTest scripts/deploy.js
This will return a contract address. Copy this address for use in the next step.
In your scripts folder, create a new file called mint.js
. Enter the following content:
Replace CONTRACT_ADDRESS with the contract address you took note of in the last step, then replace WALLET_ADDRESS with your crypto wallet address that is on the Fuji Avalanche network.
mint.js
script with the following command:npx hardhat run --network avalancheTest scripts/mint.js
You’ve minted your NFTs on the Fuji Avalanche Testnet network! You can view each image and its metadata with the following IPFS URLs:
To view a metadata file:
https://ipfs.filebase.io/ipfs/METADATA_FOLDER_CID/1
To view an image file:
https://ipfs.filebase.io/ipfs/IMAGE_FOLDER_CID/1.png
You can now repeat these steps using the Avalanche mainnet network, and you can use a folder of images that include thousands of NFT collection pieces!
