#美国非农就业数据表现优于预期 PORT3 lost 98% of its market capitalization overnight—this disaster stemmed from a fatal error during a contract upgrade.

Incident timeline review (UTC+8 2025-11-23):
At 5:35 AM, Golden Finance reported: PORT3 encountered a hacker infiltration during a system upgrade. The attackers exploited a contract vulnerability to mint 1 billion tokens out of thin air, and then crazily dumped them on the market. The price plummeted from $1.3 to $0.00004 in a matter of hours, nearly reaching zero.
What are the core flaws exposed by this incident? The minting authority in the smart contract was not adequately restricted. The lack of a multi-signature audit mechanism before the upgrade provided an opportunity for attackers.
Several prevention suggestions:
First, it is essential to check the project contract code before investing—pay special attention to whether the minting function and emergency pause mechanism are complete. Secondly, subscribe to the project's official channels and remain alert for significant upgrades. Moreover, prioritize protocols that have been audited by top security firms.
It is worth mentioning that a leading exchange quickly released an announcement at 2:30 PM, suspending PORT3USDT perpetual contract trading and executing automatic liquidation. This wave of risk control response speed indeed demonstrates the platform's crisis management capability. $BNB , as the cornerstone asset of this ecosystem, may further highlight its long-term value in such events. Some analysts believe that BNB could reach the $2000 mark by the end of the year.
