Ethereum and Solana Dominate Crypto Hack Losses in H1 2026

Crypto losses topped $1 billion in the first half of 2026 as the industry recorded its highest number of hacks in a six-month period, according to onchain security platform Blockaid.

Ethereum and Solana recorded the largest losses from incidents affecting their networks, with roughly $332 million and $326 million in stolen funds, respectively.

Blockaid tracked 212 security incidents during the period, with the largest single exploit coming from KelpDAO at $292 million.

Ethereum incurred the highest losses from incidents in H1 2026, with attackers primarily targeting vulnerabilities in applications built on the network. Code exploits dominated Ethereum incidents by count, with major losses also linked to key compromises involving Humanity Protocol and StablR. CoWSwap, an Ethereum-based decentralized exchange, was the only major Ethereum incident in the report classified as a user mistake.

Solana incurred nearly as much in losses as Ethereum during the first half of 2026, a sharp increase from the roughly $127 million in stolen funds the network recorded during 2025. Compromised keys accounted for more than 98% of Solana’s losses, driven largely by incidents involving Drift Protocol and Step Finance.
