Cardano Token Registry Questions

What is the Cardano token registry?

The Cardano token registry is an official curated list of native tokens on the Cardano blockchain. It provides a way to associate metadata, such as a token's name, description, and logo, with its unique identifier. This information helps wallets, exchanges, and other services display accurate and consistent information about the token.

What do I need to do to register a token on the Cardano token registry?

After successfully minting your token using our platform, you will be guided through the registration process with a few simple steps:

  1. Confirmation and Metadata Generation:

    • Once your token is minted, a confirmation popup will appear. This popup will provide a reference number and a link to a form you'll need to fill out.
    • Complete the form to generate a JSON file that includes all the required metadata for your token.
  2. Choosing the Registration Method:

    • Manual Registration (Free): You can choose to download the JSON file and manually submit a pull request to the official Cardano token registry repository on GitHub. Follow the instructions provided in the repository to complete your submission.
    • Assisted Registration (Fee-Based): For convenience, you can opt for our assisted registration service by simply clicking the 'Register Token' button and paying the applicable fee. Our team will handle the entire registration process on your behalf, which includes submitting your token's metadata to the registry. Please note that this process can take several days as the token registry is maintained by Cardano's team.

Choose the registration method that best suits your needs. The manual path is free and allows you more control over the submission timing, while the assisted path, although involving a fee, offers you ease and peace of mind as we take care of the technical details.

This version includes the new options available for the user, providing clear, step-by-step instructions and highlighting the choice between manual and assisted registration paths.

What do I need to do a pull request?

A pull request is a way to contribute to a project on GitHub. It allows you to take ownership of your project and submit your changes for review.

In the context of the Cardano token registry, you will need to create a pull request to add your token's metadata to the registry.

What do I need to do with the JSON received for the token registry?

Upon receiving the JSON file for the token registry, ensure to retain the original file name of the JSON you downloaded. Next, proceed by adhering to the guidance outlined in the official guide for submitting an entry to the Cardano Token Registry.

Bear in mind, the review and merge process for a Pull Request may span several days. For a detailed walkthrough, consider watching the following step-by-step video tutorial on YouTube, beginning at the 15-minute and 20-second mark, to cover the necessary steps not discussed prior to this point.

Could you do the Cardano token registration for me?

While the Cardano token registry encourages token creators to independently register their tokens to foster ownership and responsibility, we understand that the process can be complex.

Questions about the service provided

How does it work?

Our platform is a comprehensive toolbox designed for creators on the Cardano blockchain. Here's how it simplifies the process for you:
1. Choose whether you want to create a token or an NFT and fill out a simple form with the necessary details for your project.
2. After submitting the form, you'll be instructed to send a specific amount of ADA to a designated address on the blockchain. This amount covers the minting process.
3. Once we receive the specified amount, we'll take care of all the technical aspects and mint your tokens or NFT.
4. The newly minted tokens or NFT are then sent back to your wallet.
We handle the technical side of things, allowing you to focus entirely on building and growing your project on the Cardano ecosystem.

Why do I have to send you more than 17 ADA while you mentioned that it will cost 15?

When conducting a transaction with a token on the Cardano network, a minimum amount of ADA is required to accompany the token. This requirement is rooted in the technical structure of the Cardano blockchain. For a detailed explanation, refer to the official documentation.

Essentially, when we process the return of your token or NFT, it cannot be sent back without including some ADA. This is why you will receive 2 ADA along with your token(s) or NFT, ensuring the transaction adheres to Cardano's network protocols. Consequently, the effective cost of the transaction fluctuates between 15 to 16 ADA.

Why is it not free?

Because, I believe all work merits salary. And as well, remember transaction are not free.
So yes I'm taking a margin out of it, but I guess that's the way it works.
I don't force anyone to use the service

Can I try your service without paying?

Yes, you can explore and test our service without incurring any costs by utilizing the preproduction (preprod) blockchain of Cardano. The preprod environment mirrors the main Cardano network, offering a realistic testing ground for our services.

To get started, create a wallet specifically for the preprod blockchain, which will allow you to use test ADA (tADA) instead of real assets. This tADA can be used to experiment with all the products and features our service provides, including token and NFT minting, without financial commitment.

Testing on the preprod blockchain is an excellent way to familiarize yourself with our platform's capabilities and ensure your projects are fully prepared before launching on the main network. For instructions on setting up a preprod wallet and acquiring tADA, please refer to our comprehensive guide available on our website.

How can I be sure it's not a scam?

Our commitment to transparency and trust is fundamental to our service. Every transaction processed through our website is verifiable, as we openly share our blockchain address in the website's footer. This transparency allows you to conduct your research and verify the legitimacy of transactions directly on the blockchain.

Additionally, our service has played a crucial role in minting some of the most recognized tokens on the Cardano network, including the popular meme coin, SNAKE. This not only showcases our platform's capability but also affirms our credibility within the Cardano community.

We encourage our users to explore these transactions and our contributions to the Cardano ecosystem to assure themselves of our service's authenticity and reliability.

How do decimals work for native tokens on Cardano?

Understanding decimals for native tokens on Cardano involves recognizing that the smallest unit of any token is, by default, 1. This unit represents the minimum value your token can have, a foundational concept when considering decimal places. For instance, creating 100 xTokens with a setting of 2 decimal places means each xToken has a "real value" of 1.00.

Setting the decimal value to 1 implies your xTokens would effectively be divided into 10 units, allowing transactions of 0.1 tokens but not 0.12, highlighting a key difference from ERC20 tokens. The decimal value, adjustable by the token creator, plays a crucial role in the token's divisibility and its representation across wallets and exchanges. It's pivotal to determine the appropriate decimal setting post-minting, based on the total amount minted, to ensure a seamless and consistent user experience.

When registering your token's decimal places in the Cardano token registry, the value you declare influences how exchanges display your token's total supply. For example, minting 100 tokens with an intended two decimal places but registering it with one decimal place would result in a displayed total supply of 10.0 tokens on Cardanoscan, following the registry's approval of your metadata.

Opting for no decimal places simplifies the token's structure, appealing to certain use cases. Ultimately, the choice of decimal representation is a consensus between the developer and the users, with Cardano's infrastructure accommodating an integer-based system for token quantities.

What does it mean to have a dedicated wallet and access to the Skey?

If you want to have full access on your token, we offer you the possibility to mint it from a wallet where you will have full control.

If you pay an extra fee and select this option, after minting your tokens, you will be able to directly retrieve the full information on the wallet and the skey.

2 JSON files will be available for download.

One will contain the Seed Phrase that you can import with any wallet provider.

The other one will include the skey which can be useful for the Token Registry.

It guarantees you complete access to the wallet which minted the token.

Of course, you can still use our form to generate the JSON directly from our website.

The keys are stored on a secure Server where one could have access.

What is a 'skey'?

A skey or signing key is a cryptographic key that is unique to a wallet, enabling the wallet to authorize transactions on the blockchain securely. On our platform, for convenience and maintainability, all tokens are initially created using a common wallet. Because of this:

  • Security: The skey should not be shared, as possession of it would grant the ability to control the wallet and any tokens associated with it.
  • Dedicated Wallet Option: We offer the option to create your token from a new, dedicated wallet. This wallet will be used exclusively for your token, enhancing the security and autonomy of your token management.

What's the difference in the process if I pay extra for a skey and wallet?

Opting for a dedicated skey and wallet provides significant benefits:

  • Autonomy and Independence: With your own skey, you gain full control over the token registration process, including the ability to independently generate the required JSON metadata file for the Cardano token registry.
  • Flexibility: Owning the skey allows you to generate this JSON metadata either through our form or locally on your computer with appropriate tools, providing flexibility for future updates or changes.
  • Default Process Without skey: If you do not opt for the dedicated skey, you will rely on our platform's form to generate the JSON metadata. This is straightforward but means you must use our platform for any future metadata updates required by the token registry.

If I don't use this option, does this mean I don't have full control over the token I create?

Even without a dedicated skey, you maintain full control over your token in terms of ownership and total supply management. The primary consideration is how you manage updates to your token’s registry information:

  • Without the skey: You will need to use our platform’s form to generate and update the JSON metadata for the token registry.
  • With the skey: You have the option to use our form or handle the metadata generation and updates independently, giving you more control and flexibility.

Can I get the policy signing keys?

Since April 2024, we have introduced the capability to mint tokens and optionally retrieve the policy signing keys. This new feature is available for an additional fee, allowing for greater flexibility and control over your tokens.

In the meantime, you can still automatically generate the JSON file for the Cardano token registry using the reference received during your token's minting process. This step ensures your token is properly registered and meets all necessary standards within the Cardano ecosystem.

What is a policy which is not time-locked?

A non-time-locked policy on the Cardano blockchain refers to a token policy that does not have an "expiration date".

This means the policy does not impose a time limit on tokens minted or burned.

Policy owners can manage their tokens indefinitely, allowing them to mint new tokens or burn existing ones at any time in the future. This can done using the Cardano CLI command through simple transactions, providing flexibility and control over token supply.

Our service will soon offer the possibility to mint more tokens or burn some existing tokens with an open policyId.

What is the "tips" for?

When I developed the platform, I thought that it would be funny to be linked to some projects who want to share their Native Tokens. Moreover, what happens if in one or two years your new ada native tokens are worth a lot? This is a completely optional feature, that I thought would be cool.

Why is my token displayed as collectible in Nami?

Your tokens are displayed as collectibles in Nami due to an issue with NAMI. We mint tokens using the CIP-25 Cardano metadata structure, which is necessary for displaying a logo on However, this structure is also used for NFTs, causing Nami to be unable to differentiate between collectibles and tokens.
To avoid this issue, you could decide mint tokens without using the CIP-25 standard (advanced options) , but this would prevent logos from being visible on
If you prefer, you can move your tokens to another wallet like Eternl, which will not display them as collectibles.

How can I be sure my NFT is unique?

That's an excellent question.
Your NFT will be composed of three elements: a policyID, an asset Name, and a quantity.
For NFTs, all of these components shall be UNIQUE, otherwise it's not an NFT anymore.
To ensure we cannot use the same POLICY ID again in the future and potentially create another similar NFT, we are using a Time-Locking policy.
Long story short again: we make sure that this policyID cannot be used after the specific slot on the blockchain.
To be fully transparent, the slot number is automatically sent with the metadata when you receive the token.
It's accessible in the following property of the metadata object: mintedBeforeSlotNumber.

How can I see my NFT content?

An NFT is a token but you generally link a file with it.
On our platform, we accept images, videos, and audio files up to 15mb.
When your transaction is confirmed, the file is automatically pinned on an IPFS node.
This means that your file will be permanently accessible, and almost impossible to delete.
You will receive the IPFS hash of your file in the transaction metadata.
If you want to visualize it, you can use the official IPFS gateway:
Example:{{YOUR IPFS HASH}}
You can also see your minted token or NFT on You will find the link in the confirmation message.

Which file type are you accepting for NFT?

On our platform, we accept images, videos, and audio files up to 15mb.
If you need something specific, just contact us at

Can I create an NFT collection on your website?

I prefer to be honest and let you know that, for the moment on my website, we don't provide solutions to create collections of NFT.
Each NFT minted comes with a different policy.
If you really want to create a collection, I suggest turning towards services such as NFT-MAKER PRO.
With that in mind, otherwise, my service works well for single NFT.

What is IPFS?

The InterPlanetary File System (IPFS) is a protocol and peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting all computing devices.
Check the official website.

Why can't I use my Kraken, Binance, or Coinbase Account?

Because it's not your personal wallet. When you have ADA on an exchange platform, it's centralized in a pool. Only when you withdraw it to a personal wallet will you be the real owner of your ADA.

General questions about the blockchain

What is a NFT?

Official documentation from WIKIPEDIA:
A non-fungible token (NFT) is a unit of data stored on a digital ledger, called a blockchain, that certifies a digital asset to be unique and therefore not interchangeable. NFTs can be used to represent items such as photos, videos, audio, and other types of digital files. Access to any copy of the original file, however, is not restricted to the buyer of the NFT. While copies of these digital items are available for anyone to obtain, NFTs are tracked on blockchains to provide the owner with a proof of ownership that is separate from copyright.
