Polish legislators were unable to override President Karol Nawrocki’s veto of a digital-assets bill, effectively halting Prime Minister Donald Tusk’s push to implement crypto regulations aligned with EU standards.

Upbit, South Korea’s largest cryptocurrency exchange, has removed all previously issued deposit addresses as part of its ongoing wallet maintenance. Users will need to create new addresses before making deposits. Starting December 5 at 17:00 KST, deposits and withdrawals for 33 assets across 21 networks will be restored in stages. The update comes in the aftermath of the November 27 security incident that resulted in roughly 44.5 billion KRW in losses.
Anthropic的新研究表明,現代人工智能代理已經發展出顯著的能力來複制鏈上漏洞。在模擬2020年至2025年真實智能合約攻擊的測試中,Claude Opus 4.5、Sonnet 4.5和GPT-5大約重現了460萬美元的歷史漏洞結果。在分析2849個新部署的合約(沒有之前報告的問題)時,模型還識別出兩個未公開的漏洞,並生成了有利可圖的攻擊場景。報告總結稱,人工智能驅動的漏洞活動正在迅速增長,預計收入每1.3個月翻一番——這表明自主、以利潤爲動機的智能合約利用現在已經在技術上可行。
