Ethereum, Solana Lead Crypto Losses in Record-Breaking H1 2026 Hack Wave

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 were the hardest-hit blockchains, with roughly $332 million and $326 million in stolen funds, respectively. These losses are largely driven by key compromises, specifically from incidents affecting their networks.

The largest single exploit came from KelpDAO at $292 million, while Blockaid verified 3.4 times as many high-threshold exploits in H1 2026 compared to all of 2025.
