Creating a Token-2022 on Solana

Quickly mint a Token-2022 compliant SPL token on Solana Devnet or Mainnet using the command-line interface (CLI).

This guide explains how to quickly mint a Token-2022 compliant SPL token on Solana Devnet using the command-line interface (CLI). It also shows how to enable and use token extensions such as metadata and transfer fees.

Prerequisites

1. Install Solana CLI

   sh -c "$(curl -sSfL https://release.solana.com/stable/install)"

2. Install SPL Token CLI (must support Token-2022)

   cargo install spl-token-cli

3. Set Up Solana CLI for Devnet

   solana config set --url https://api.devnet.solana.com
   solana config set --keypair /path/to/your/dev-wallet.json

4. Airdrop Some SOL for Fees

   solana airdrop 2

Step-by-Step Token-2022 Minting

1. Create a Token-2022 Mint

spl-token create-token \
  --program-id TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb

Save the returned token mint address.

2. Create a Token Account for Your Wallet

spl-token create-account <TOKEN_MINT_ADDRESS> \
  --program-id TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb

3. Mint Tokens to Your Account

spl-token mint <TOKEN_MINT_ADDRESS> 1000 \
  --program-id TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb

4. Confirm Token Balance

spl-token accounts --program-id TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb

Adding Token Extensions

Token-2022 supports advanced features called extensions. Below are examples of two useful ones.

Extension 1: Transfer Fee

This allows collecting fees on every token transfer.

Create Mint with Transfer Fee Extension

spl-token create-token \
  --program-id TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb \
  --enable-extensions transferFeeConfig

Initialize Transfer Fee

spl-token enable-transfer-fee \
  <TOKEN_MINT_ADDRESS> \
  --transfer-fee-config-authority <YOUR_WALLET_ADDRESS> \
  --transfer-fee-basis-points 25 \
  --maximum-transfer-fee 10

This sets a 0.25% fee (25 basis points) with a max of 10 tokens per transfer.

---

Extension 2: Metadata

This enables rich token metadata like name, symbol, and image.

Initialize Metadata

spl-token initialize-metadata <TOKEN_MINT_ADDRESS> \
  "My Test Token" "MTT" "https://example.com/token-metadata.json"

Make sure the JSON metadata file at that URL is hosted and follows the standard format.

Notes

• You must use the --program-id Tokenz... flag for all Token-2022 interactions.

• Some extensions require initializing during the token mint creation.

• Not all wallets or exchanges currently support Token-2022 tokens.
