Trust Wallet Assets Info

Overview

Trust Wallet token repository is a comprehensive, up-to-date collection of information about several thousands (!) of crypto tokens.

Trust Wallet uses token logos from this source, alongside a number of other projects.

The repository contains token info from several blockchains, info on dApps, staking validators, etc. For every token a logo and optional additional information is available (such data is not available on-chain).

Such a large collection can be maintained only through a community effort, so feel free to add your token.

How to add token

Please note that brand new tokens are not accepted, the projects have to be sound, with information available, and non-minimal circulation (for limit details see https://community.trustwallet.com/t/how-to-submit-a-token-logo/3863).

Assets App

The Assets web app can be used for most new token additions (Github account is needed).

Quick starter

Details of the repository structure and contribution guidelines are listed on the Developers site. Here is a quick starter summary for the most common use case.

Adding an ERC20 token checklist:

Make sure your smartcontract has more than 2,500 address holders, otherwise you will be rejected
Fork the Github repository
Create folder with name of token smartcontact address in checksum format blockchains/ethereum/assets/<token_smartcontract_address>/.
Tell your designer that token image must be in PNG format, avoid transparent background, recommended size 256x256px, max. 512x512px, with max file size of 100kB, for further details read image rules.
Upload your logo with file named logo.png to previously created folder with smartcontract address, and if you done all correctly your path should look like this. blockchains/ethereum/assets/0x1234567461d3f8Db7496581774Bd869C83D51c93/logo.png
Create info.json file with info about the token/project
Create a pull request to the main repo
Pay the processing fee

On Checks

This repo contais a set of scripts for verification of all the information. Implemented as Typescript scripts, available through npm run check, and executed in CI build; checks the whole repo. There are similar check logic implemeted:

in assets-management app; for checking changed token files in PRs, or when creating a PR. Implemented as a Typescript library, checks diffs, can be run from browser environment.
in merge-fee-bot, which runs as a GitHub app shows result in PR comment. Also uses library, but executes in a non-browser environment.

Trading pair maintenance

Info on supported trading pairs are stored in tokenlist.json files. Trading pairs can be updated -- from Uniswap/Ethereum and Panckaswap/Smartchain -- using update script (and checking in changes). Minimal limit values for trading pair inclusion are set in the config.ts file. There are also options for force-include and force-exclude in the config.
