🛡️ Secure DeFi Timelock Vault

Demonstrating Smart Contract Security & Asset Protection

Project Overview

This repository contains a professional Ethereum vault designed to protect assets. It implements a mandatory 24-hour withdrawal delay to prevent immediate theft if a private key is compromised.

Key Security Features

• 24h Timelock: Prevents instant withdrawals, providing a critical reaction window.
• Reentrancy Protection: Implements OpenZeppelin's ReentrancyGuard to prevent recursive call attacks.
• Emergency Pause: Includes a circuit breaker function for administrators to freeze assets during threats.
• Access Control: Secured via the Ownable pattern.

Technical Proof (Security Test)

The following screenshot demonstrates the vault's security logic in action. An attempt to withdraw funds immediately after depositing results in a transaction revert, as the 24-hour lock is active:
