Setup Candy Machine

Create New Wallet

// Optional: Make a folder if you dont already have one
mkdir ~/my-solana-wallet

// Make wallet within folder
solana-keygen new --outfile ~/my-solana-wallet/my-keypair.json

// Get wallet address
solana-keygen pubkey ~/my-solana-wallet/my-keypair.json

// Use wallet address to verify with keypair
solana-keygen verify <PUBKEY> ~/my-solana-wallet/my-keypair.json

// Config wallet
solana config set --keypair  ~/my-solana-wallet/my-keypair.json

// Devnet Fund wallet
solana airdrop 1 <PUBKEY> --url https://api.devnet.solana.com

// Config Network (devnet)
solana config set --url https://api.devnet.solana.com

Create whitelist spl token

// Optional: Create Token w/ custom vanity
solana-keygen grind --starts-with US:1

// Create Token (If using custom vanity)
spl-token create-token <TOKEN WITH VANITY> --decimals 0

// Create Token (if NOT using custom vanity start here)
spl-token create-token --decimals 0

// Create token account
spl-token create-account <TOKEN>

// Create token supply
spl-token mint <TOKEN> <NUMBER TOKENS TO CREATE>

// Check token supply
spl-token balance <TOKEN>

Distribute SPL Tokens via Gumdrop (Optional)

// Create JSON file with dist list of wallet address
example-dist.json
[
  {
    "handle": "<DISTRIBUTION-METHOD-SPECIFIC-HANDLE>",
    "amount": <GUMDROP-CLAIM-ALLOWANCE>,
    ["edition": <EDITION-NUMBER>]
  },
]

// Run Gumdrop to distribute SPL token
npx ts-node js/packages/cli/src/gumdrop-cli.ts create -k <KEYPAIR> --claim-integration transfer --transfer-mint <SPL TOKEN> --distribution-method wallets --distribution-list example-dist.json
