Centralized Exchange Failure attacks on Ethereum

An attacker hijacked a Binance Ethereum hot wallet via an EIP-7702 delegation and swept an estimated $6.3 billion across several chains — the largest theft in crypto history.

Attackers compromised Bitget's wallet backend to spoof withdrawals and drain roughly $387.5 million across eight blockchains, in 2026's largest crypto theft.

Canada's largest crypto exchange collapsed when its CEO 'died' in India holding sole access to ~$190M in customer funds; regulators later ruled it a Ponzi.
