Rainbow Wallet Assets

Overview

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

Rainbow Wallet uses token logos from this source

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.

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 lowercase 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. Please us Image Optim or similar on larger files.
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

Scripts

There are several scripts available for maintainers:

make check -- Execute validation checks; also used in continuous integration.
make fix -- Perform automatic fixes where possible
make update-auto -- Run automatic updates from external sources, executed regularly (GitHub action)
make add-token asset_id=c60_t0x4Fabb145d64652a948d72533023f6E7A623C7C53 -- Create info.json file as asset template.
make add-tokenlist asset_id=c60_t0x4Fabb145d64652a948d72533023f6E7A623C7C53 -- Adds a token to tokenlist.json.

On Checks

This repo contains a set of scripts for verification of all the information. Implemented as Golang scripts, available through make check, and executed in CI build; checks the whole repo. There are similar check logic implemented:

in assets-management app; for checking changed token files in PRs, or when creating a PR. Checks diffs, can be run from browser environment.
in merge-fee-bot, which runs as a GitHub app shows result in PR comment. Executes in a non-browser environment.
