Your Contract is Your Backend 🧠

Think of a traditional app: you have a frontend (UI) and a backend (server). In Web3, your smart contract is the backend!

"In JavaScript, this means..." your app doesn't call a cloud function; it talks directly to the blockchain to handle payments, data access, and storage.

Nice! Once you deploy your contract with Hardhat, you’ll get two "golden keys" to unlock the front-end connection:

1. Contract Address: The unique location of your "brain" on the blockchain.

2. ABI (Application Binary Interface): A JSON "menu" that tells the front-end exactly which functions it can call.

With just these two elements, your React app is ready to rock the VeChainThor network!

Note: VeChainThor recently upgraded its "heartbeat" to Delegated Proof of Stake (DPoS) for better decentralization, so your backend is running on cutting-edge tech!
