This is a general purpose tokenlist generation app that Balancer uses to generate it's tokenlist.

To make changes to the balancer tokenlist edit the files in src/tokenlists/balancer.

1. metadata.ts - Edit this to change the highlevel tokenlist metadata.
2. tokens/<network>.ts - Edit this to add or remove tokens from the generated tokenlist. E.g Tokens for Arbitrum go in tokens/arbitrum.ts, tokens for Ethereum go in tokens/ethereum.ts.
3. overwrites.ts - Edit this to overwrite any token data that is incorrect when generated automatically.

Once changes are made, the tokenlist can be regenerated by running:

npm run generate

This updates the generated file at /generated/balancer.tokenlist.json

However, you do not need to run this command locally. Simply make changes to the mentioned files and merge them with the main branch. Following this, an autogenerated PR will be created to update the generated tokenlist files.

Although this repo is primarily for maintaining the balancer.tokenlist.json file, it can be forked and used to generate any kind of tokenlist. Simply run:

npm run tokenlist:create my-new-tokenlist

This will create a new template tokenlist in /src/tokenlists with the necessary files. Then, just add token addresses to the tokens.ts file and run npm run generate to generate your tokenlist json file.

To run the generate command locally or in the Github actions of a fork you will need to add these ENV variables:

DRPC_KEY=xxx
INFURA_KEY=xxx
ALCHEMY_KEY=xxx
COINGECKO_API_KEY=xxx

You'll need to sign up for each of those services to get keys:
