Launch and mint your first NFT collection

Time: 15-30min
The Comet SDK lets you launch new Solana NFT collections, and lets anyone mint them using a credit card. Never worry about a wallet private key or clunky fiat onramp again.
First things first
You’ll need your Comet API key and Comet publishable key. For instructions, go to the link below:
Getting Started
In addition, if you want to launch a paid NFT collection, you need to set up Stripe x Comet to send payments to your bank account. To do this, go to withcomet.com/settings/payments and log in using the same phone number you used to create your API key.
Launching a new collection
To launch a new collection, you’ll need one thing - an image. Preferably 840x840, which will be part of the membership pass. Once you have that file on your computer, you’re ready to get started.
The examples in this doc will use cURL to call the Comet REST API, but you can do this via Javascript, Python, or any other language you’d like!
To launch a collection using the Comet REST API, you’ll need the following information:
1.Your Comet API key (see First things first above)
2.The name and symbol you want for your NFT
3.The description of the membership pass
4.The price you want to sell your pass for (in USD)
5.The maximum supply of the token
6.The path to the image on your computer
Once you have those ingredients, you can call the REST API as follows:
curl -X POST 'https://api.withcomet.com/v1/collection' \
     -H "Authorization: Bearer <COMET API KEY>" \
     -F name='my test collection' \
     -F symbol='TEST' \
     -F description='whats good' \
     -F price=10 \
     -F maxSupply=100 \
     -F backgroundUpload=@/path/to/image.jpg
You’ll get a result that looks like this:
{
  "id": "f4b2e771029e",
  "name": "my test collection",
  "symbol": "TEST",
  "type": "milky_way_nft",
  "chainType": "solana",
  "chainId": 101,
  "subtype": "numbered_pass",
  "description": "whats good",
  "infiniteSupply": false,
  "maxSupply": 100,
  "price": 10,
  "pricingModel": "pay_once",
  "deployed": false,
  "isCometToken": true,
  "backgroundUpload": "VYkbVHtWhV3LakmWYhOVMMURs24Adk9yH1Bp6G1W4dklE1fZIfaMuJqdvSkzKOwl"
}
Congrats! You’ve started to deploy your first NFT collection with Comet. You can use the id to retrieve this collection from the API later on:
curl -X GET 'https://api.withcomet.com/v1/collection/<ID>' \
     -H "Authorization: Bearer <COMET API KEY>"
Once deployed is equal to true, you’re officially live on Solana mainnet! Usually deployment takes 30-60 seconds.
Letting others mint your collection
Comet provides a React component you can drop in to any project, which lets any user mint your NFT (including accepting credit card if the NFT requires it). To get started, create a new Create React App project (instructions are in the link). Once you’ve created it, just do the following:
First, install the Comet React SDK (v1 alpha) in your project:
npm install --save @comet-labs/react
In your index.js, you will need to wrap your entire app in a CometProvider. The CometProvider component unlocks Comet's Web3 functionality for the rest of your app's components. You will need to provide your Comet publishable key here.
index.js
import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import './index.css';
​
import { CometProvider } from '@comet-labs/react';
​
const cometProviderConfig = {
  publishableKey: '<PUBLISHABLE KEY>',
}
​
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <CometProvider config={cometProviderConfig}>
      <App />
    </CometProvider>
  </React.StrictMode>
);
Then, in your App.js, you can simply import the MintButton component and drop it into the page. Here you will need the collectionId from the collection you created earlier in the tutorial.
App.js
import logo from './logo.svg';
import './App.css';
import { MintButton } from '@comet-labs/react';
​
function App() {
  return (
    <div className="App">
      <MintButton
        collectionId="<ID>"
      />
    </div>
  );
}
​
export default App;
Run npm run start and you’ll see a mint button. Now mint your NFT with a credit card without ever touching a crypto wallet!
