Crypto losses topped $1 cardinal successful the archetypal fractional of 2026 arsenic the manufacture recorded its highest fig of hacks successful a six-month period, according to onchain information level Blockaid.
Ethereum and Solana recorded the largest losses from incidents affecting their networks, with astir $332 cardinal and $326 cardinal successful stolen funds, respectively, Blockaid said successful its H1 2026 information study published Tuesday.
Blockaid tracked 212 information incidents during the period, with the largest azygous exploit coming from KelpDAO astatine $292 million, portion the level verified 3.4 times arsenic galore high-threshold exploits successful H1 2026 arsenic crossed each of 2025.
Code exploits drove Ethereum incidents, portion breaches of keys and signing infrastructure accounted for astir Solana losses, according to the report.
Ethereum losses reflected the risks of high-value protocols
Ethereum incurred the highest losses from incidents successful H1 2026, with attackers chiefly targeting vulnerabilities successful applications built connected the network.
Blockaid said codification exploits dominated Ethereum incidents by count, with large losses besides linked to cardinal compromises involving Humanity Protocol and StablR. CoWSwap, an Ethereum-based decentralized exchange, was the lone large Ethereum incidental successful the study classified arsenic a idiosyncratic mistake.

Blockaid identified respective communal onslaught methods targeting Ethereum, including bugs successful bridges and astute contracts, unauthorized entree to privileged accounts and marketplace manipulation techniques.
The study said Ethereum remains a large people due to the fact that it hosts galore of the crypto industry’s astir invaluable applications, including restaking platforms, stablecoins and decentralized exchanges.
Solana losses surged arsenic attackers shifted focus
Solana incurred astir arsenic overmuch successful losses arsenic Ethereum during the archetypal fractional of 2026, a crisp summation from the astir $127 cardinal successful stolen funds the web recorded during 2025.
“2025 had $2.58 cardinal mislaid crossed 63 incidents, concentrated successful Q1 by Bybit’s $1.5 billion, with Ethereum and Arbitrum the apical chains by stolen-fund flow,” Blockaid CEO Ido Ben-Natan told Cointelegraph.

The alteration did not stem from a emergence successful astute declaration exploits. Instead, compromised keys accounted for much than 98% of Solana’s losses, driven mostly by incidents involving Drift Protocol and Step Finance, which Blockaid linked to North Korea-linked cyber groups.
Unlike Ethereum, wherever attackers chiefly exploited vulnerabilities successful protocol code, Solana incidents targeted signer infrastructure and organizational security, portion a fistful of codification exploits involving Raydium and Volo accounted for the remaining losses.
