The $6.3 Billion Binance Hack: Keys Held, Signing System Failed, Freeze Button Saved Nearly Half

Hackers drained about $6.3 billion from Binance hot wallets in 20 minutes using its own signing system. Stablecoin freezes stopped nearly half. What executives and users should ask now. On the evening of October 29, 2026, around 20:05 UTC, Binance’s own signing systems authorized transfers of approximately $6.3 billion from its hot wallets across ten blockchains. Most of the funds left in about 20 minutes. That is four times the previous record set by Bybit in February 2025 and, according to Elliptic, almost certainly the largest theft of any kind on record.
