aribaBank is a simple yet powerful example of a transparent, decentralized banking system built entirely on the blockchain.
It allows users to deposit, withdraw, and transfer ETH securely — all actions are recorded on-chain for full transparency.
This project aims to teach Solidity beginners how to handle Ether transactions, mappings, modifiers, events, and security mechanisms such as reentrancy protection.
Mission Summary
To teach Solidity beginners how decentralized banking logic works on-chain.
To demonstrate secure handling of ETH using best practices.
To provide a transparent, easy-to-understand example of deposits, withdrawals, and transfers.
To help developers learn key Solidity concepts such as events, mappings, ownership, and reentrancy protection.
To create a foundation that can be expanded into more advanced DeFi applications.
Problem:-
Beginners learning Solidity struggle to understand how to securely manage ETH inside smart contracts.
Common challenges include handling deposits, withdrawals, internal transfers, and preventing security vulnerabilities like reentrancy.
There is a lack of simple, transparent examples that show how an on-chain banking system works end to end.
Developers need a clear reference project demonstrating ownership control, events, mappings, and transaction handling on the blockchain.
Solution
aribaBank provides a beginner-friendly smart contract that enables secure deposits, withdrawals, and transfers of ETH.
The contract uses mappings for balance tracking and exposes functions for checking personal and public balances.
Security is enforced through nonReentrant protection, owner-only emergency withdrawal, and structured modifiers.
All actions (deposit, withdraw, transfer) are logged with events, ensuring transparency on-chain.
The project serves as a practical learning tool for understanding Solidity fundamentals.
