Step 1: Create Your Shop

Head over to and connect your wallet.

After connecting your wallet, you can create your own shop.

Now, your shop is ready. Take note of the parameters candyShopCreatorAddress, treasuryMint, and candyShopProgramId, we will use them in Step 2.

Step 2: Setup your shop repo locally

Fork and clone our ready-made React storefront locally

git clone

Install npm packages


Define your environment variables (.env file)

Rename the .env.example file at the root directory to .env and update the following variables in the .env file with the parameters you got from Step 1:


In the .env file, define the blockchain network you want to connect to:


Options are:

  • Ethereum: ETH (mainnet) and GOERLI (testnet)
  • Polygon: MATIC (mainnet) and MUMBAI (testnet)

You can also specify an RPC server that your web app will access the Ethereum or Polygon network through.


Run your code locally

yarn start

Your shop should now be live on localhost:3000

Edit the code to customise your storefront

Step 3: Deploy your shop

When you’re happy with how your shop looks, commit and push your code to github and you can one-click deploy your shop with Vercel. With that, your shop is live!

That’s a wrap!
