IMHO Looks even better 🚀

How about maintaining grip stuff as external, testing library?

What do you mean 👀? It's currently a separate crate in the workspace.

I am thinking about having it as a dedicated repository. So our smart contracts will need to have additional dependency, but future developers may only import this dedicated repository instead of fetching the smart contract library. Just as an open idea, no effort needed.

So you would be able to use grip by just running cargo add grip. If we haven't published yet to crates.io, devs could pull grip by specifying this repo as a git dependency. You can learn more about this in the cargo docs.

It would look like this:

[dependencies]
grip = { git = "https://github.com/OpenZeppelin/rust-contracts-stylus.git" }

Looks awesome!
One question I have. How did you come up with the name grip?

So I wanted it to have something to do with Stylus so I searched on google what parts constitute a stylus pen, and the grip seemed appropriate.

Do you like it?
