 Node Extensions are a game-changing enhancement to our existing production node. This feature allows devs to create custom JSON-RPC method names and write custom JS/TS code snippets that are executed each time the method is called. It’s like having your very own sorcerer’s apprentice working behind the scenes! 🧙‍
