🧾 Intellectual Property Registration DApp (Blockchain)

A simple decentralized application (DApp) for registering and managing intellectual property (IP) using blockchain technology.
Users can register patents, copyrights, trademarks, and other forms of IP securely on the blockchain.

⚠️ Note: This DApp works only with MetaMask.
MetaMask is required for wallet connection and blockchain interactions.

⚙️ Smart Contract Setup

Before running the DApp, you must add your own contract ABI and contract address.

Steps:

1. Write your Solidity contract (e.g., ipregistry.sol).
2. Open Remix IDE (browser-based Solidity compiler).
3. Paste your Solidity code into a new file.
4. Compile the contract using Remix Compiler.
5. Deploy it to Sepolia Test Network using MetaMask.
6. After deployment:
   • Copy the ABI → paste it into abi.js
   • Copy the Contract Address → paste it into config.js

Without adding ABI + address, the app cannot interact with the blockchain.
