Adding chain logos to chain definitions

[haardikk21]

Viem has a large repository of chain definitions which are often used (at least by me) in the backend when doing chain-agnostic data parsing/data collection

Sometimes when doing that then it's helpful to spin up a frontend to make sense of the data. For visual appeal, or if you plan on sharing that frontend with others, a task that can be quite annoying is setting up a mapping of all chain id's to logos (which I need to gather from a variety of sources)

With viem already having a great place to put it, I'd love to see an imageUrl or logo property added to chain definitions to save us that headache. Whether the images themselves should be hosted on the wevm GitHub org, or reference image links from across the internet (CryptoLogos, official brand kits, X, Farcaster, etc) - I don't have an opinion on

Sample use case: looping over all chains supported by Viem and figuring out native currency balances on those chains across a few different wallets to try and see if i have leftover dust somewhere i've forgotten about

Unfortunately we are not interested in Viem being the source of truth for this info at the moment. If something changes in the future, I will update this thread.
