Currently, you need to import every single address for your Cardano Wallets which is not ideal user experience. With Cardano, a new wallet address is usually generated for every transaction meaning you could have hundreds of addresses to import, and it’s easy to miss one.
Cardano wallets have a single staking key associated with them from which it is very easy to find all associated address. Please support importing a single Cardano address which finds all associated addresses from the parent staking key.
I’m happy to advise your team on the technical aspects of this, feel free to reach out.
Also, I think staking rewards should also be included, but there is another feature request for this already.
