The problem Hotkeys solves

HotKeys aims to make ux better when it comes to product keys, instead of using text based keys which are then stored in a centralised database, we can rather leverage nft's as product keys, and take advantage of its features like easy transferability and storablity and original creator royalty whenever it is transferred.
let's take a situation,
Imagine that you're a video editor or even a music professional with a lot of products and plugins to manage Now, every one of these products comes with a product key. And you'll have to manage all that product key in a file or somewhere.
If you're switching machines, you have to authenticate every product with their product key again, not very user friendly.
what if you just connect to your wallet, for example, and it just authenticates your plugins and products just through the NFTs there, that should make your ux better.
Let's take another example. Imagine you're a company who's selling some software. Now as a user, who finds a better product, or just dosen’t use it up anymore, would sell up the used product keys on any marketplace, just how old windows activation keys are sold, which is technically decreasing your user base and your revenue, and you're not even getting royalty for it. But what if on every resale of your product, you'll get a royalty, replacing the traditional old hex keys with NFTs.
we allow you to benefit from NFTs features, like better transferability, giving royalty to the creator every time it's transferred.
and better storability.

Challenges I ran into

I have been working with evm based chains, so most of my work has been in solidity/frontend, but for this picking up rust to write smart contracts for solana proved to a great challenge, and then testing them up.
