Multi-sig Security in 2026 — What Bybit Lost, and Five Mistakes That Cost Less but Hurt Worse

Описание: Bybit didn't lose to a hack. It lost to a UI. Here's what actually happened — and the five cheaper ways to lose money the same way.

$1.4 billion. 401,347 ETH. Signed by three people on hardware wallets. The biggest theft in crypto history wasn't a flaw in multi-sig and it wasn't a Safe contract exploit — the contracts were never touched. It was the layer above them. This is the full breakdown, and the five mistakes that put your own setup at the same kind of risk for free.

WHAT YOU'LL LEARN
• What actually happened at Bybit — the real attack chain, in plain language
• Why "Safe was hacked" is wrong: the protocol-vs-application boundary
• Why the architecture held and the interface didn't
• Five multi-sig mistakes that are cheaper to make and far more common
