I'm trying to test this branch on Arbitrum but it only shows me Ethereum tokens:

@jmealy did you manage to get it to show Arbitrum tokens?

@jmealy did you manage to get it to show Arbitrum tokens?

I got it working now, I didn't have Arbitrum in the config.

I was using chainlist to see what Tokens to support for each chain, but it told me Arbitrum used ETH, so I only added that: https://chainlist.org/?chain=42161&search=42161

Do you want to it just have Arbitrum tokens or Etherium also?

Edit: adding both for now

Tested on the new chains, it now works and lists tokens on those chains correctly. ✅
