If I had the sHBD for 20 days, and used it after that, will I still get the 20 day's worth of interest?
No. The interest stays with sHBD. Where sHBD goes the interest goes (but only when unstaked as HBD and based on the 30-day distribution of interest on HBD in savings).
Wow, that is interesting. If that is true, then a person who wasn't keeping track of their sHBD can lose all their interest. I guess I need to unstake my savings then restake if I want to use my sHBD. Thanks.
I don't know of any interface yet that integrated sHBD and VSC wallets. Do you? It's probably too early.
I think in one of the comments they said that it will be available in 3-4 months. So I think any interface that integrates with it will be after that.
