HalloApp allows users to deposit, withdraw, and track their Ether savings directly on the blockchain.
Every transaction (deposit or withdrawal) is stored permanently on-chain with a timestamp — ensuring complete transparency and security.
This project is designed for beginners learning Solidity and blockchain app development using the Celo network or EVM-compatible blockchains.
Our mission is to create a simple, transparent blockchain fund system that removes trust issues in online money collection. Using a Solidity smart contract, anyone can deposit, everyone can view the balance, and only the owner can withdraw. This ensures security, transparency, and zero misuse of funds.
People donate money online, but they don’t know where the money goes.
Many donation websites lack transparency.
Solution With Your Smart Contract
A smart contract where:
✔ Anyone can deposit money
✔ Balance is visible publicly
✔ Only the owner can withdraw
✔ No scam because the contract is public
