Hello everyone,
trust you all good, I know this is kind of off topic, but I feel this is the best place seek for better insight. been working on a dex fronted and have noticed the use of token lists in Uniswap, PancakeSwap, and SushiSwap and I have went through their repos. I'm trying to understand how these tokenlists were hosted, and consumed on the frontend APIs. 
I checked the token list repositories of various platforms, but I'm finding it difficult to understand the entire procedure. Balancer, have their own even more complex.
Please has anyone worked on similar projects? I'd be grateful if you could offer some insight on how these token lists are actually managed, hosted, and consumed. Any thoughts or advice?
