Great article. I prefer the Greymass wallet and in early days they had released a cold storage feature built in to sign transactions offline (believe it would allow an air-gap computer to function like a hardware wallet).
One thing you might consider to look into is Chintai leasing service for idle tokens. There are 7 day to 28 day leases at the moment. The thing is you have to use Scatter currently versus other wallets, if I recall correctly. I've been considering going through with it because the APRs reached crazy levels in the recent week.
I had saw that option a couple of weeks ago! It was one of the reasons I wanted to get my tokens on a wallet. However, as you mention, they only tie with Scatter at the moment. I’m waiting to see if they do anything to add others. If not, given how widely used Scatter is, I may create another account with Scatter.
