Crypto industry losses from hacks surpassed $1 billion in the first half of 2026. A recent security report from Blockaid revealed that the industry faced 212 security incidents in just six months. This officially marks the highest number of incidents in crypto history for a single six-month period. Across all incidents, the Ethereum and Solana ecosystems bore the heaviest financial hit with nearly equal losses of $332 million and $326 million, respectively.
The spread of these attacks becomes clear when compared to data from the previous year. Throughout 2025, total losses reached $2.58 billion, but that figure came from just 63 incidents, heavily concentrated in the $1.5 billion hack of the Bybit exchange in the first quarter. In 2026, the attack profile shifted toward numerous mid-level exploits. Blockaid, quoting CEO Ido Ben-Natan, verified that high-threshold exploits this year surged 3.4-fold compared to the entirety of 2025. Amid the widespread attacks, the largest single loss of the half fell on KelpDAO, which lost $292 million.
Code Bugs vs. Key Compromises
Although total losses between Ethereum and Solana were separated by only $6 million, hackers’ entry vectors into the two ecosystems were starkly different. On the Ethereum network, the primary vulnerability centered on code or smart contract bugs. Major projects directly victimized by these flaws included Humanity Protocol and StablR. The sole anomaly in the Ethereum ecosystem occurred at decentralized exchange CoWSwap, which Blockaid noted as a major incident purely resulting from user error rather than an inherent flaw in the application.
Solana’s vulnerability did not stem from smart contract code. Instead, more than 98% of losses on the Solana network arose from private key compromises or exploits targeting transaction signing infrastructure. This wave of key thefts was closely linked to North Korean cyber groups targeting established protocols like Drift Protocol and Step Finance. While pure code exploits still occurred on Solana, they were relatively minor and only affected projects such as Raydium and Volo.
Solana Replaces Arbitrum
The high rate of access key leaks reshuffled the ranks of the most frequently breached networks. The $326 million loss officially pushed Solana past Arbitrum to become the industry’s second hardest-hit ecosystem, trailing only Ethereum.
For the crypto industry, the record surge to 212 incidents demonstrates that hackers are no longer bothering to look for loopholes in smart contract code; they are going straight after key holders.
