Crypto Losses Soar to $1 Billion as Hackers Target High-Value Protocols

The first half of 2026 saw crypto losses top $1 billion as hackers exploited vulnerabilities in high-value protocols, according to onchain security platform Blockaid.

Ethereum and Solana were hit hardest, with roughly $332 million and $326 million in stolen funds, respectively. Code exploits dominated Ethereum incidents by count, while breaches of keys and signing infrastructure accounted for most Solana losses.

Blockaid tracked 212 security incidents during the period, with the largest single exploit coming from KelpDAO at $292 million. The platform verified 3.4 times as many high-threshold exploits in H1 2026 as across all of 2025.
