Launch a Token

Create a token on Spark, mint supply, and send your first token transfer.

Create and launch your first token on Spark in minutes. This quickstart will walk you through setting up your wallet, issuing a token, minting supply, and sending your first transfer. All on Spark, without touching L1 or waiting for confirmations.

1. Setup: Run the CLI

   Clone and launch the Spark CLI, powered by the Spark SDK:

   CLI

   # Clone the Spark SDK repo
   git clone https://github.com/buildonspark/spark.git
   
   # Navigate to the JS folder
   cd spark/sdks/js
   
   # Install dependencies and build the SDK
   yarn && yarn build
   
   # Navigate to the JS CLI example
   cd examples/spark-cli
   
   # Start the CLI
   yarn cli
   
2. Initialize your wallet

   Create a wallet to serve as the issuer of your token:

   CLI

   > initwallet
   

   Example output:

   CLI

   Mnemonic: rhythm torch mistake reopen device surround cabin wish snake better blind draft
   Network: REGTEST
   

   Important: Keep your mnemonic safe and offline. The wallet you create here becomes the root of trust for your token. It’s the only wallet authorized to mint or burn supply.

3. Create a token

   Launch your token directly on Spark:

   CLI

   > createtoken <tokenName> <tokenTicker> <decimals> <maxSupply> <isFreezable>
   # Example:
   > createtoken MyToken MTK 6 1000000 false
   

   View Token Parameters

   name · string · required

   Human-readable name of the token.

   ticker · string · required

   Short symbol for the token (typically 3–6 characters).

   decimals · number · required

   Decimal precision used for display and arithmetic.

   maxSupply · number · required

   Hard cap on total mintable supply.

   freezable · boolean · required

   Whether the issuer can freeze or unfreeze token balances.

   CLI

   TxID: 9c5d17acb7fe203ab6342b3f556b4e5f3b4dabe1bca3b0b98b1b3d9cf7d92c4d
   Token ID: btkn1qv6cps0n0ttm3p4gx62rzty4rjhzqwe5eqv2wlt
   

   View Response Fields

   txId · string · required

   Spark transaction ID of the token creation.

   tokenId · string · required

   Bech32m token identifier (e.g., btkn1…) used in later operations.

   Your token now exists on Spark. It’s ready for minting and transfers.

4. Mint tokens

   Bring new tokens into circulation. Only the issuer wallet can mint, up to the max you set before.

   CLI

   > minttokens 500000
   

   Example response:

   CLI

   Minted: 500000 MTK
   Remaining mintable: 500000 MTK
   

   You can verify the token balance:

   CLI

   > gettokenbalance
   Token: MTK
   Balance: 500000
   
5. Send tokens

   Tokens on Spark move instantly and cost nothing. You can choose to create a new wallet to find a sender.

   CLI

   # Wallet 2
   > initwallet
   Mnemonic: explain bullet cradle segment lava enable someone lemon bracket fossil invite crash
   > getsparkaddress
   sparkrt1pgw6rrt6s4y3xghx6cl5v4mm08eylktaygff62mg8uk3u5zqq2zwqf9t9d0
   

   Then send tokens from your issuer wallet:

   CLI

   # Wallet 1 (Issuer)
   > transfertokens btkn1qv6cps0n0ttm3p4gx62rzty4rjhzqwe5eqv2wlt 100000 sparkrt1pgw6rrt6s4y3xghx6cl5v4mm08eylktaygff62mg8uk3u5zqq2zwqf9t9d0
   

   That’s it. The transfer settles instantly on Spark.
