distributed tool library software for keeping track of where lent out stuff is so the next person can borrow it

Looking for open source free software for building a tool library.

I have a hammer, or post-hole digger, or circular saw. I can list it so people know i’m open to lending it. When someone borrows it, it gets listed as with them. The original owner of the tool (or really any physical object, from decorative lace curtains to a book) is tracked, if the initial giver does not disclaim ownership of it, but more importantly

If the NFT people really wanted a better world and weren’t grifters this is what they’d have done with their non-fungible tokens running on a world computer, but i don’t think anyone is doing anything close to this in that space.

Surprised i cannot find it anywhere else, either.

Maybe i should look attached to timebank software…
