Repository structure

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 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.

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list of address approved based on many criterias (TODO add criterias) and disapproved based on factors such as scam, outdated, abandoned contracts etc ...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.
