EtherVault Contract

Overview

EtherVault is a secure and efficient smart contract built on Solidity that allows users to deposit and withdraw Ether. The contract includes robust features such as restricted access for administrative functions, individual balance tracking, and event logging for transparency. It is a demonstration of Solidity skills and secure coding practices, showcasing ability to design, deploy, and test smart contracts professionally.

Features

• Deposit and Withdraw: Users can deposit Ether to the contract and withdraw their balances anytime.
• Owner Privileges: The contract owner has exclusive rights to withdraw all funds from the contract.
• Event Logging: Emits events for deposits and withdrawals to provide transaction transparency.
• Balance Tracking: Maintains user-specific balances securely.
• Test Coverage: Includes comprehensive test cases using Foundry for deposit, withdrawal, and edge-case scenarios.

Usage

Prerequisites

• Install Foundry for Solidity development and testing.
• A funded wallet for interacting with the deployed contract on the Sepolia testnet.

Deploy the Contract

1. Clone the repository:

   git clone https://github.com/NishantCoder108/EtherVault.git
   cd EtherVault

2. Deploy the contract:

   forge create --rpc-url <your_rpc_url> --private-key <your_private_key> src/EtherVault.sol:EtherVault --constructor-args <owner_address>

Interact with the Contract

• Deposit: Send ETH to the contract using the deposit function.
• Withdraw: Call the withdraw function with the desired amount.
• Owner Withdraw All: The contract owner can withdraw all funds using the withdrawAll function.

---

Tests

The project includes a complete test suite written in Foundry to ensure correctness and security:

1. Run tests locally:

   forge test

2. Test cases include:
   • Initial setup validation
   • Deposit and withdrawal scenarios
   • Edge cases for invalid actions
   • Owner-specific functions
