Blockchain-based TODO List with Ganache

A decentralized application (DApp) that provides a simple TODO list, backed by Ethereum smart contracts. This DApp communicates with a smart contract deployed on a local blockchain managed by Ganache.

🛠 Prerequisites

Ganache - Personal blockchain for Ethereum development Metamask - Crypto wallet & gateway to blockchain apps Node.js - JavaScript runtime

🚀 Getting Started

1. Setup Ganache Launch Ganache and initiate a local blockchain. Remember your RPC server details.

2. Deploy the Smart Contract Navigate to the repo's root:

bash

truffle migrate --reset

This deploys the smart contract to the local Ganache blockchain.

1. Update ABI and Contract Address Post-deployment, make sure to update TODO_LIST_ABI and TODO_LIST_ADDRESS with the new contract's ABI and address respectively.

2. Setup Metamask Install and launch MetaMask. Connect it to your local Ganache blockchain using Ganache's RPC URL. Import a Ganache account into MetaMask with the account's private key.

3. Running the DApp bash

cd todo
npm install
npm start

Open a browser, access the application, connect via MetaMask, and manage your TODOs!
