Sorry but you need to have an account with Etana custody service, complete their KYC process, and open a joint account (venture) with Kraken
using your public account ID
This isn't Etana. No goddamn way would I sign up with them. They sound like deadbeats.
This is a new service with an operation called Clear Junction. There's no indication of needing a separate sign up. I'd like that to be confirmed. I won't bother if it is required.
