Assets and Metadata Structure

Collection Structure

NFT asset files (images,audio, video, GIFs) and metadata.json file to respective assets.

Note: to link the respective assets(images/videos) with respective metadata, it is very important to have the Folder structure in the following format for Assets represtnation and minting.

Folder Structure:
  - images
    - 1.jpg
    - 2.jpg
    - 3.jpg
  - metadata
    - 1.json
    - 2.json
    - 3.json

type - String, bool, number, URI, height

How to Structure the metadata?

// 1.json
{
  "properties": [
    {
      "name": "Block",
      "type": "String",
      "value": "Flash"
    },
    {
    "name": "Eyes",
    "type": "String",
    "value": "black"
    },
    {
    "name": "edition",
    "type": "number",
    "value": 1
    },
    {
    "name":"rare",
    "type": "bool",
    "value": true
    },
  ],
  "description": "This is the sample metadata file",
  "image": "ipfs://baadasdalasdas/images/1.png",

NFT Collection Upload

Once the assets and metadata files are ready, next step is to upload the same at some storage mechanism. It is recommended to use decentralized storage solution such as IPFS.

Option 1 : Using NFT.storage and script

Please ensure that your images are named numerically in a sequential manner.

Steps

Note: Install nodejs in your system
sudo apt install nodejs npm -y
sudo npm i -g npm@latest
sudo npm i -g yarn@latest
sudo npm i -g ts-node@latest

# Create a nft-upload-project directory
# Move your images and metadata folders there
mkdir nft-upload-project
cd nft-upload-project

# Folder Structure
Project
├── nft-upload (tool folder)
    ├── images (assets/images folder)
    ├── metadata (metadata folder)

# Install dependencies
# Change your directory to script folder
cd nft-upload
yarn install

# Create an API on nft.storage and Copy that API key

# Paste that APIKey in config.js file (nftStorageAPIKey) there.
yarn nft-storage-upload

Option 2 : Using Web3.storage and script

Note: Steps are same as NFT.Storage.upload
Note: Install nodejs in your system
sudo apt install nodejs npm -y
sudo npm i -g npm@latest
sudo npm i -g yarn@latest
sudo npm i -g ts-node@latest

# Create a nft-upload-project directory
# Move your images and metadata folders there
mkdir nft-upload-project
cd nft-upload-project

# Folder Structure
Project
├── nft-upload (tool folder)
    ├── images (assets/images folder)
    ├── metadata (metadata folder)

# Install dependencies
# Change your directory to script folder
cd nft-upload
yarn install

# Create an API on web3.storage and Copy that API key

# Paste that APIKey in config.js file (web3StorageAPIKey) there.
yarn web3-storage-upload
