👨‍🔬How to Create a Token

How to create your own NEP-141 Token with no coding required

Create a Token in Two Steps

Step 1: Set the Basics

1. Token Name: Input the desired name of your token.

   • Ex: Bitcoin, Ethereum, Jump Token, Neko Token

2. Symbol: Input the desired symbol of your token.

   • Ex: BTC, ETH, JUMP, NEKO

3. Token Image: Paste a link to your token logo; a small image associated with your token. The token logo image must be formatted as a Data URL to enable fast loading while protecting user data. It is recommended to upload an optimized SVG file, which allows for high resolution images and small storage costs.

   • Convert your token logo image into a optimized SVG file here.

   • Upload optimized SVG file as a Data URL:

     • Download IPFS to your desktop.

     • 

       • Import the optimized SVG file of your token logo to IPFS.

       • Click "Share Link" and copy the link to your Data URL.

       • Paste your Data URL into the Token Image section of the Jump Token Laboratory.

4. Decimals: Select the quantity of decimals for your token. Decimals refer to how divisible a token can be, from 0 (not at all divisible) to 18 (pretty much continuous) and even higher if desired. Ethereum uses 18 decimals and it is the standard for ERC-20 tokens. This is a safe choice for the majority of token use-cases.

5. Reference (Optional): A link to a valid JSON file containing various keys offering supplementary details on the token.

   • Example: /ipfs/QmdmQXB2mzChmMeKY47C43LxUdg1NDJ5MWcKMKxDu7RgQm, https://example.com/token.json, etc. If the information given in this document conflicts with the on-chain attributes, the values in reference shall be considered the source of truth.

6. Hash Reference (Optional): The base64-encoded sha256 hash of the JSON file contained in the reference field. This is to guard against off-chain tampering.

Step 2: Setup the Tokenomics

Welcome to the final step of your token creation journey! Now you must select either a fixed supply token or a mintable supply token.

Once the token type is selected and you input desired supply quantities (maximum supply for fixed token or initial supply for mintable token) you are all set to create your token!

Fixed Supply Token

The fixed supply token establishes a maximum supply for your NEP-141 token. Tokens with a maximum supply are standard for the majority of use-cases. Select this token type if scarcity is the intent of your tokenomics.

Mintable Supply Token

The mintable supply token enables you to increase the supply of your token, supply is unlimited. You will define an initial supply of tokens to be minted which can be increased per your requirements. A mintable supply token is often used for in-game currencies or other use-cases where scarcity is not a desired factor.
