April 2026 has gone down as one of the most damaging months in the history of decentralized finance, with more than $635 million lost across 28 separate exploit incidents. The scale, frequency & diversity of these attacks highlight a growing imbalance in the ecosystem where innovation continues to accelerate, but security maturity struggles to keep pace.

April recorded 28 exploit incidents in just 30 days, averaging nearly one attack per day. This level of activity is unprecedented and signals that attackers are actively scanning the ecosystem for vulnerabilities across all layers.

The incidents ranged from large-scale protocol breaches to smaller, repeated attacks targeting weak contracts, poorly designed permissions & user-level vulnerabilities. EtherWorld’s ongoing coverage throughout the month reflects this rising trend, including phishing-based attacks such as the $585K Ethereum phishing drain in 11 hours, showing that not all exploits require breaking smart contracts.
