How to add a token to the List of coins & tokens supported by Trezor?

Follow eight simple steps to add your Ethereum token to the Trezor List.

Step 1. Get a token address in ERC-55 format

Use this application to convert your token’s smart contract address to the ERC-55 format. To pass Trezor verification you should use the ERC-55 address format in the steps described below.

Step 2. Open Github

After signing Github, go to that page.

Step 3. Create a File on Github

Click on the Add file button. Then press on ‘Create new file’.

Step 4. Enter the name

Enter the name of your file. It should be your ERC20 token’s smart contract address but in ERC-55 format. Example: 0x3D371413dd5489F3A04C07c0C2CE369c20986ceb.json
Don’t forget to add a .json extension into the file name.

Step 5. Write the code

The simplest way to write a code for your token is to copy the example below. Just copy-paste the code below and edit by entering your token parameters. Replace YOUC with your token symbol, enter your token smart contract address, decimals, and so on.

{
  "symbol": "YOUC",
  "address": "0x3D371413dd5489F3A04C07c0C2CE369c20986ceb",
  "decimals": 10,
  "name": "yOUcash",
  "type": "ERC20",
  "ens_address": "",
  "website": "https://youengine.io",
  "logo": {
    "src": "https://i.ibb.co/jV6Ymn4/youc-lolo-square-128x128.png",
    "width": "128",
    "height": "128",
    "ipfs_hash": ""
  },
  "support": {
    "email": "info@youengine.io",
    "url": "https://youengine.io"
  },
  "social": {
    "blog": "",
    "chat": "",
    "facebook": "https://www.facebook.com/YouEngineOfficial",
    "forum": "",
    "github": "",
    "gitter": "",
    "instagram": "",
    "linkedin": "https://www.linkedin.com/company/youengine-io",
    "reddit": "",
    "slack": "",
    "telegram": "https://t.me/YouEngineGroup",
    "twitter": "https://twitter.com/younive87630435",
    "youtube": "https://www.youtube.com/c/YOUengine"
  }
}

Note that the required parameters that you must include in the code are:

• symbol: Short ticker style symbol of your token.
• name: long token name token (take it from Ethercsan).
• address: Ethereum address of ERC-20 token, but in ERC-55 format
• decimals: The decimals of the token. As Number and not String.

Optional parameters are the following:

• logo: An optional logo of your token. Must be a square (recommended: 128×128) PNG w/ transparent background.
• support: A support email, support URL, or other way people can get assistance regarding the token.
• website: the link to your project website, and
• other links to your project’s social accounts.

We suggest you include as much as possible parameters.

Step 6. Check and confirm

After you entered the file name and code (as on the picture above), scroll down and click on ‘Propose new file’

Step 7. Create a pull request

Confirm your submission two times as shown below. Also, you can add a comment like “Add [your token name] token”. As the result, you create a Pull Request.

Step 8. Wait for checking

If you successfully created the file (without any errors) then you see the status of your Pull request as verified (colored green on the picture below).

Note that your request will require additional checking. It will be done by Trezor’s authorized team. Your need just wait for passing it.

Also, you can check the status of your request in this folder.
Gray color means that the request is under checking. A green checkmark means that Pull Request has successfully passed Trezor checking.

Trezor team will review your issue and give feedback. They will confirm if they would like to add your token in the firmware. Otherwise, they will decline. Please note that they can not merge each and every token.

When your Pull Request successfully passes all checking, you see it in this section. It means that Pull Requests merged into the Master. After that, just wait for the next Trezor firmware update to see your token in the List.

I can’t pass Trezor verification. What to do?

If you can not pass the verification then review your code, fix errors, and create a file again as described in 1-7 Steps above. If it doesn’t help, contact us via telegram, we will help.

What’s the Trezor?
