Ethereum, Solana Lead Crypto Hacks with $1 Billion in Losses

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.

Ethereum incurred $332 million in losses, while Solana lost around $326 million. The largest single exploit came from KelpDAO at $292 million. Code exploits drove Ethereum incidents, while breaches of keys and signing infrastructure accounted for most Solana losses.

The report said 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. Blockaid identified several common attack methods targeting Ethereum.

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.
