// TODO
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 Ethereum like networks and inside of it logo.png
- image representation. Note: Lowercase or uppercase contract addresses are considered as invalid. You can find the checksum address by searching on etherscan.io, for example stablecoin DAI the checksum address is 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 the address must be specified as it was originated on the chain, e.g TRON TRC10: 1002000
, TRON TRC20: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t
etc ...
info
folder contains for now only logo.png
that represents the 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list of address approved based on many criterias (TODO add criterias) and disapproved based on factors such as scam, outdated, abandoned contracts etc ... .

After PR was merged, set of cron workers will update token status normally with in 10 minutes and sometimes up to 30 minutes and token became visible in search result.
A process of removing smart contract information such as (token logo and info) from this repository. Removed contract address will be added to the blacklist and, as a result, will no longer be present in token search results inside the TW app. Why would you want to do this ?. You are contract owner or just good samaritan who noticed contract to be no longer "active" and was an upgrade and abandoned by owning organization, involved in a scam, mimicking by its name or/and symbol a real contract. All facts must be supported with a link to any resource proving these statements.
