TLDR
Crypto protocols lost around 630 to 650 million dollars to hacks in April 2026, the worst hacking month for crypto in years.
- Data from multiple security firms shows 28 to 40 April exploits with losses estimated between 625 and 651 million dollars, a record incident count and highest losses since early 2025.
- Two giant DeFi hacks on KelpDAO and Drift Protocol made up over 90 percent of the damage, with several reports linking them and many smaller attacks to North Korean Lazarus Group activity.
- Markets reacted by pulling billions from DeFi and pricing in a "security risk premium," while analysts warn that operational security and bridges matter as much as smart contract audits.
Deep Dive
1. How Bad April Was
DefiLlama data cited by several outlets confirms April 2026 as the most hacked month in crypto history by incident count, with 28 to 30 exploits and more than 625 million dollars stolen. One summary pegs losses above 625 million dollars, while another DeFi-focused report puts the total at about 635.2 million dollars across 28 exploits.
Blockchain security firm PeckShield reported 647 million dollars lost in April, up 1,140 percent month over month, and counted around 40 major exploits, underlining that estimates vary but all cluster in the 630 to 650 million dollar range.
Confidence: high, because multiple independent datasets (DeFiLlama, CertiK, PeckShield) converge on similar totals.
2. Main Culprits and Attack Methods
Two attacks dominated the month: a roughly 293 million dollar bridge exploit on KelpDAO and a 285 million dollar drain on Drift Protocol, together responsible for about 90 to 93 percent of April losses according to The Defiant.
TRM Labs and other researchers link both incidents to North Korean state-backed hackers, with some analyses estimating DPRK-linked groups account for roughly three quarters of 2026 hack value so far. Smaller April incidents hit lending markets, vaults, CEX hot wallets, and front ends, often via oracle tricks, key compromises, or phishing.
risk is concentrated in a few large protocols and bridges, but the long tail of smaller bugs and key leaks never really goes away.
3. Market Impact And What To Watch
The KelpDAO exploit alone triggered more than 10 billion dollars in TVL outflows from DeFi bridges and lending platforms, and one review notes over 14 billion dollars in value exited protocols after the major hacks in April.
Research from crypto.news and others describes mid-cap DeFi tokens selling off 5 to 8 percent in short windows as traders priced in a persistent "security risk premium," rotating toward perceived safer venues and large caps. Prediction market odds for aggressive Ethereum and Bitcoin upside in April also weakened following the hacks.
Key things to watch now are: how quickly affected protocols restore backing or compensate users, whether more bridge and infrastructure incidents pop up, and whether insurers and auditors change standards for admin keys, multisigs, and monitoring.
security posture is becoming a direct pricing factor for DeFi and bridge tokens, so users and builders who treat it as core fundamentals, not a checkbox, are better positioned.
Conclusion
Aprils roughly 635 million dollars in hack losses show that a few sophisticated, infrastructure-level attacks can outweigh years of incremental security gains. The concentration in KelpDAO and Drift, plus a record number of smaller incidents, has pushed markets to treat security as part of valuation rather than an afterthought. Going forward, the most important signals are how protocols harden bridges and operations and whether the industry can reduce reliance on single points of failure like weak multisigs and centralized verifiers.
