Ethereum validator withdrawals spike 72,000% amid $625M DeFi hacks, causing a 7-day withdrawal delay

Ethereum's validator withdrawal queue surged to 433,158 ETH, a 72,000% increase in two weeks, driven by major DeFi security breaches in April 2026 that caused $625 million in losses. The largest single hack was the $292 million KelpDAO bridge exploit linked to North Korea's Lazarus Group. This triggered widespread withdrawals and a 7-day delay for validator fund access, though staking entry remains strong with 3.6 million ETH queued. Despite the turmoil, total staked ETH holds steady at 38.6 million, suggesting a sector rotation rather than a mass exit from staking.
