Mr D Baker: We are unable to add any tokens on Uniswap, since they do not have an API we can use at the moment.

Blockfolio Karl: rocketpool says uniswap?

Mr D Baker: RPL is in their API. If it shows up in search on their site, it's in their API. Tokens that don't show up in search and have to be imported are not in their API. It seems like Uniswap has completely stopped adding to their API. These dexes always do this.
