Node Provider Protection with JWTs in Frontend dApps

This project demonstrates how to protect node provider API keys (e.g., for services like Alchemy) in frontend dApps using JWTs. By leveraging short-lived JWTs, we can securely manage access to node providers without exposing API keys directly in the frontend. For a detailed explanation, check out the blog post here, and see the solution in action in the demo app.
