next-candy-machine

The Candy-Machine-Mint project is designed to let users fork, customize, and deploy their own candy machine mint app to a custom domain, ultra fast.

This Candy Machine takes heavily from Exiled Apes and kevinfaveri, and would not be possible without them, but attempts to simplify and provide an easy-to-follow and complete guide.

This guide will not cover topics such as XXX.

I recommend using Linux to make this process as easy as possible.

Getting Set Up

Prerequisites

• Ensure you have recent versions of both node and yarn installed.

• Follow the instructions here to install the Solana Command Line Toolkit.

• Follow the instructions here to install the Metaplex Command Line Utility.

  • Installing the Command Line Package is currently an advanced task that will be simplified eventually.

Installation

1. Clone the project

git clone https://github.com/maxwellfortney/next-candy-machine

2. Install yarn dependencies

cd next-candy-machine
yarn install

3. rename the .env.template file at the root directory to .env.local.

Initialize treasury SOL keypair

1. Set URL to devnet

solana config set --url https://api.devnet.solana.com

2. Generate a new keypair

solana-keygen new --outfile ~/.config/solana/devnet.json

2. Set the keypair in your Solana config

solana config set --keypair ~/.config/solana/devnet.json

This will output our 1st required environment variable into the terminal as pubkey, and will be our treasury SOL address. Set NEXT_PUBLIC_TREASURY_ADDRESS in our .env.local to this address.

3. Airdrop SOL to wallet (repeat command if desired)

solana airdrop 1

Create, upload, and verify images and metadata

This guide will not cover creating images and metadata. For more info see Token Metadata Standard as well as Prepare NFT Assets.

The following commands assume your images and metadata are located at the home directory under nft-assets ~/nft-assets/.

1. Upload assets

ts-node ~/metaplex-foundation/metaplex/js/packages/cli/src/candy-machine-cli.ts upload ~/nft-assets --env devnet --keypair ~/.config/solana/devnet.json

This will output our 2nd required environment variable into the terminal as initialized config for a candy machine with publickey, and will be a SOL address. Set NEXT_PUBLIC_CANDY_MACHINE_CONFIG in our .env.local to this address.

If initialized config for a candy machine with publickey if not output into the terminal, delete the file located at ./cache/devnet-temp.json and re-run the command in step 1 above.

2. (Optional, but recommended) Verify your assets. If all is well, this command will finish with output ready to deploy!

ts-node ~/metaplex-foundation/metaplex/js/packages/cli/src/candy-machine-cli.ts verify -k ~/.config/solana/devnet.json

Create a candy machine

1. Run the following command to create a candy machine

ts-node ~/metaplex-foundation/metaplex/js/packages/cli/src/candy-machine-cli.ts create_candy_machine -k ~/.config/solana/devnet.json

This will output our 3rd required environment variable into the terminal as candy machine pubkey, and will be a SOL address. Set NEXT_PUBLIC_CANDY_MACHINE_ID in our .env.local to this address.

Update our new candy machine

We need to set a price in SOL, as well as a mint start date for our candy machine.

1. This command will set the price to 1 SOL, and the mint start date to the current time in epoch time.

ts-node ~/metaplex-foundation/metaplex/js/packages/cli/src/candy-machine-cli.ts update_candy_machine -k ~/.config/solana/devnet.json -p 1 -d now

This will output our 4th required environment variable into the terminal as updated startDate timestamp, and will be a epoch time. Set NEXT_PUBLIC_CANDY_START_DATE in our .env.local to this time.

We are done!!

You can now start the NextJs app by running yarn dev and navigating to http://localhost:3000/, connect your desired wallet and begin minting your devnet new NFTs.

Deployment to Vercel and migration to mainnet-beta

Changing your .env.local variables

1. Change NEXT_PUBLIC_SOLANA_NETWORK to mainnet-beta
2. Change NEXT_PUBLIC_SOLANA_RPC_HOST to https://api.mainnet-beta.solana.com your preffered RPC URL such as QuickNode

Deploying to Vercel

1. Connect your Github account to Vercel
2. Create a new project from your repo
3. Before clicking Deploy, add all of your environment variables
4. Click Deploy
