Hello and welcome to Trust Wallet assets info contribution guide. We appreciate your effort to open-source. Token repository https://github.com/trustwallet/assets (repo) is a source of images used by Trust Wallet including:
BEP2 Binance DEX token (native marketplace on Binance Chain)
TRC10, TRC20 tokens on TRON blockchain
Staking validators info available on Trust Wallet Staking Platform
Coming soon: token info, token price
Prepare image requirements
Get familiar with folder strcture, will give you understanding where asset image should be placed
PNG considered invalid.
name：file name requirements for:
logo.png name, but folder naming where they placed is most important part of contribution
256px by 256px
background: preferably transparent
use simple drag and drop online service tinypng to optimize image size
blockchains folder contains many subfolders and represents chains e.g.
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 etherscan.io, 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.
whitelist.json files you may find in folders like
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list of address approved based on many criterias (TODO add criterias) and disapproved based on factors such as scam, outdated, abandoned contracts etc ... .
