🧠 What is RPC?

RPC = Remote Procedure Call

It’s just a way for one computer (like your app) to talk to another computer (like an Ethereum node) over the internet — and ask it to do something.

In Web3, that means:

• You send requests like:

  → "Hey node, what’s the balance of this address?"

  → "Hey node, run this smart contract function!"

The Ethereum node listens and responds.

🧰 Example in Real Life

Imagine:

• You = DApp frontend
• Ethereum Node = Blockchain librarian
• RPC = Your phone call to ask for info

You say:

📞 “What’s Arif’s token balance?”

The librarian says:

📚 “It’s 23.4 tokens.”

That “phone call” is RPC.
