How to add an image to the CoW Swap default token list

In order to add a new token to the CoW Swap default token list follow these steps

  • Find an icon with reasonable quality/size (256px, <100kB).
  • Add the icon to src/public/images/<chainId>/<address>.png 1
  • Upload the image to IPFS (https://www.pinata.cloud/ is a simple recommended service to do that)
  • Create a new entry in src/public/CowSwap.json containing token address, symbol, etc. (use IPFS link for icon!)
  • Make sure you bump the version using SemVersions
  • Create a PR with these changes

Setup

# Install dependencies
yarn

# Generate Coingecko list
yarn coingecko

Download images

There's a script that will fetch all images form the CowSwap list and store them in src/public/images/<chainId>/<address>.png

yarn downloadImages
