April 2026 turned out to be a major crisis in the crypto world. According to CertiK, a blockchain security company, the total amount lost to hacks, scams, and exploits this month crossed $650.9 million.
This makes it the worst month for crypto losses since March 2022, when the industry lost about $715 million.
Big Actions Cause Losses
According to CertiK documentsmost losses are due to exploitation rather than fraud or fraud.
The biggest spend came from KiloEx, which alone lost about $291.3 million. This was followed by Drift Protocol, which lost an estimated $285.23 million, making it one of the biggest events of the month.
Meanwhile, other well-known threats included Rhea Finance at $18.47 million, Grinex at $16.23 million, and using the contract marked 0x8B84 with a loss of about $6.585 million.


Wallet Hacking Caused Losses
Looking at the amount of money lost, the wallet was the biggest group, which cost more than $610 million.
Cost-cutting measures came in second at about $18.88 million, followed by code risk at about $17 million.
Meanwhile, the fraud attacks, while minor, still cost $3.57 million across multiple incidents. The final raid ended the series at $544,703.
DeFi Will Remain the Biggest Focus
CertiK’s crash shows that DeFi platforms continue to be the most affected sector. By sector, DeFi platforms were hit hard, losing about $609.39 million in April alone.
Central platforms posted losses of about $8.48 million, while game-related projects lost about $3.41 million.
Minor damages were recorded in bridges ($2.83 million) and other categories totaling approximately $9.85 million.
What This Means for the Crypto Market
The number of security incidents also increased steadily from January to April, with April recording the highest number of incidents.
The increase in damage is creating new security concerns for the entire industry. While innovation continues to advance the field, these developments highlight the urgent need for robust research, risk management, and user awareness.
Despite these obstacles, the industry has shown resilience in the past.
