Solana storage fees are not one-and-done. You have to pay "rent" over time to maintain that data's persistence on-chain.

If you don't pay, your data could get garbage collected 🗑️

Interestingly, if you gain "good credit" (not a real term) by paying rent for 2 years, then you no longer have to pay rent for that [non-executable] account

You can prepay for 2 years and get permanent storage, right? Also iirc you get a refund if you delete paid for storage?

Wow, so the docs are out of date on this one. Apparently, as of June 2022, you *must* prepay 2 years for your account storage. "Rent" doesn't really exist anymore.

But yes, you get your SOL back if you delete your data. The full amount, too, regardless of time.

Interesting, wonder what the issue was... or maybe just simplifying the logic.
