Key facts
- Total crypto losses reached over $1 billion in the first half of 2026.
- Ethereum recorded approximately $332 million in stolen funds, while Solana lost around $326 million.
- A total of 212 security incidents were tracked by Blockaid during the period.
- The largest single exploit involved KelpDAO, resulting in $292 million in losses.
- Code exploits were the primary cause of incidents on Ethereum, whereas key compromises dominated Solana's losses.
Crypto security incidents resulted in over $1 billion in losses during the first half of 2026, marking the highest number of hacks in a six-month period, according to a report by onchain security platform Blockaid.
Ethereum remained the most affected blockchain, with approximately $332 million stolen, primarily due to code exploits targeting vulnerabilities in applications built on the network. These included bugs in bridges and smart contracts, unauthorized access to privileged accounts, and market manipulation. Blockaid noted that Ethereum's high value and the presence of numerous valuable applications like restaking platforms, stablecoins, and decentralized exchanges make it a prime target.
Solana experienced the second-highest losses, with around $326 million stolen. This represents a significant increase from previous periods. Unlike Ethereum, Solana's losses were largely driven by compromised keys and signing infrastructure, accounting for over 98% of the total. Incidents involving Drift Protocol and Step Finance were linked to North Korea-linked cyber groups. While code exploits did occur on Solana, they were less prevalent than key compromises.
Overall, Blockaid tracked 212 security incidents in H1 2026, a substantial rise compared to previous periods. The largest single exploit identified was from KelpDAO, which resulted in $292 million in losses. The report also highlighted a 3.4 times increase in high-threshold exploits in H1 2026 compared to the entirety of 2025.
