No we'll still offer custodial accounts and regular old layer 1 non-custodial bitcoin wallets. Ark will be an optional separate account type for people to try and just another layer that we support receiving into the custodial wallet.

Eventually I might start limiting the custodial accounts so people won't be able to hold large balances there but will still be able to use them for small zaps etc.
