Why Using tx.origin Can Hack Your Smart Contract (Real Exploit)

Описание: In this video, we break down one of the most dangerous beginner mistakes in Solidity: using tx.origin for authentication.

You’ll learn the real difference between msg.sender and tx.origin, why tx.origin is unsafe, and how attackers exploit this mistake to drain smart contract wallets.

This is a real-world Solidity exploit, explained step by step for beginner and intermediate Web3 developers.

What you’ll learn:
What msg.sender and tx.origin actually represent in the EVM
Why tx.origin should NEVER be used for authorization
A real Solidity exploit using tx.origin
How attackers bypass owner checks with malicious contracts
The correct and secure way to protect smart contracts

If you’re learning Solidity, Ethereum, or Web3 security, this is a must-know vulnerability.

🚫 One wrong line can cost millions.
✅ Learn it once. Never make the mistake again.
