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

yarn

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
