🔓 The $600 Million Poly Network Hack — And the Hacker Who Gave It Back

In August 2021, the decentralized finance (DeFi) protocol Poly Network was hacked for over $600 million in crypto assets — the largest DeFi exploit in history at the time.

🧑‍💻 The hacker exploited a vulnerability in Poly Network’s smart contracts to drain funds from Ethereum, BNB Chain, and Polygon. The crypto world watched in disbelief as massive transactions appeared on-chain.

🪙 But the twist? Within days, the attacker began returning the funds — bit by bit — claiming they did it “for fun” and to “expose vulnerabilities.”

🎭 The hacker, dubbed “Mr. White Hat,” was even offered a $500,000 bounty and a job by Poly Network (which they refused).

💬 The event raised serious questions about DeFi security, ethics in hacking, and how the community handles gray-hat attackers.
