This repo is convenient for assets owner to update some off-chain information such as website, twitter, etc. of asset displayed in Subscan.

1. Fork this repository
2. If there is no asset you want to update in the description file in the ./assets directory, then create a new file first like ./assets/<any name>.json, and the file format refers to template.json and Description file. Then update the information you need to update in the description file
3. If you need to update the logo, put your logo to ./logos/<network_category_symbol>.<svg/png>, network is the domain part in hostname.
4. Finally, make a pull request to our repo, and replace placeholders of Asset Owner & Signature Account, Signature Hash or Your Identity
5. Done, now you can create and wait for the PR Checker to pass your request, and our team will double-check and confirm your request
6. After pr is merged, we will release new version (usually in one or two days), and asset info will be updated on Subscan.

Some naming conventions about logo file:

• File Extension: png/svg (Uppercase PNG/SVG is considered invalid)
• File Name: network_category_symbol.<png/svg> (e.g. acala-testnet_asset_ABC.png)
• Size: Less than 30KB
• Background: Preferably transparent

In Subscan, assets are currently divided into five categories: asset, system, custom, erc20, and erc721. If the asset category you update is asset, you need to sign your updated description file:

1. Copy the entire description file content
2. You can use polkadot apps signing to sign. In the polkadot apps signing, use the owner or admin account of the asset to sign the file content
3. Then you can get the signed information.

asset, system, custom, erc20, erc721

You can fill in " " for those that cannot be answered at present. No insulting or disrespectful words.

• TokenID: asset/token id or contract address
• TokenSymbol: asset/token symbol
• Logo: asset/token logo
• Description (en): description in English
• Description (zh): description in Chinese
• Website Link: website link
• Twitter Link: twitter link
• Telegram Link: telegram link
• Discord Link: discord link
• Medium Link: medium link
• Github Link: github link
• Category: one of Asset categories

1. Make sure you haven't changed other formats except for angle brackets(<>) and included words
2. Make sure the signature you put is made by the same Asset Owner/Admin
3. Make sure your description file is in valid JSON format
4. Probably our Signature checker give up its job :(
