Hello and welcome to Trust Wallet assets info contribution guide. We appreciate your effort to open-source. Token repository (repo) is a source of images used by Trust Wallet including:

  1. ERC20, ERC223 tokens on Ethereum compatible networks supported by Trust Wallet such as:

  2. BEP2 Binance DEX token (native marketplace on Binance Chain)

  3. TRC10, TRC20 tokens on TRON blockchain

  4. coins integrated in Wallet Core

  5. DApp images available in Browser section in Trust Wallet and at and bookmarks icons. read requirments

  6. Staking validators info available on Trust Wallet Staking Platform

  7. Coming soon: token info, token price

Contribution steps

  1. Prepare image requirements

  2. Get familiar with folder strcture, will give you understanding where asset image should be placed

Image Requirements

  • File location: must be placed in the correct folder and subfolder within the folder structure.

  • File extension: png. Uppercase PNG is considered invalid.

  • File name:logo.png.

  • Dimension: 256px by 256px or 512px by 512px.

  • Background: preferably transparent (should fit dark mode as well; black logos need light border/background).

  • File size: up to 100KB. Tip: optimize image size, e.g. using simple drag-and-drop online service tinypng.

blockchains folder contains many subfolders and represents chains e.g. ethereum, binance ...

assets folder contains token folders named by smart contract address in checksum address for Ethreum like networks and inside of it logo.png - image representation. Note: Lowercased or uppercased contract addresses considered invalid. You can find checksum address by searching on, for example stablecoin DAI checksum address located at the top left corner of the page and has both uppercase and lowercase characters. Or convert Ethereum address to Checksum address. For other networks address must be specified as it was originated on a chain, e.g TRON TRC10: 1002000, TRON TRC20: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t etc ...

info folder contains for now only logo.png that represents coin image

validators folder contains folders: assets same structure as above and list.json information about validators.

blacklist.json and whitelist.json files you may find in folders like tron, ethereum but not limited to, contain list of address approved based on many criterias (TODO add criterias) and disapproved based on factors such as scam, outdated, abandoned contracts etc ... .

Why do I still see old logo in Trust Wallet after uploaded new one

Both clients, Android and iOS keep old image cache for up to 7 days. In order to see changes immediately, reinstall Trust Wallet. But as always, make sure you have a backup of all your wallets.
