being new to Bolt, I am not fully confident that Bolt is being used efficiently. If someone could just look over the code and check if the use is reasonably efficient, that would be great.

Ditto. I'm also working on a bolt wrapper and would hugely appreciate a quick check too!

The aim of the wrapper is to streamline simple transactions and key prefix/range scanning.

Any hints, tips, or suggestions would be greatly appreciated!

FWIW, the README now provides a quick overview.
