Crypto losses topped $1 billion within the first half of 2026 because the business recorded its highest variety of hacks in a six-month interval, in response to onchain safety platform Blockaid.
Ethereum and Solana recorded the most important losses from incidents affecting their networks, with roughly $332 million and $326 million in stolen funds, respectively, Blockaid mentioned in its H1 2026 safety report printed Tuesday.
Blockaid tracked 212 safety incidents throughout the interval, with the most important single exploit coming from KelpDAO at $292 million, whereas the platform verified 3.4 instances as many high-threshold exploits in H1 2026 as throughout all of 2025.
Code exploits drove Ethereum incidents, whereas breaches of keys and signing infrastructure accounted for many Solana losses, in response to the report.
Ethereum losses mirrored the dangers of high-value protocols
Ethereum incurred the best losses from incidents in H1 2026, with attackers primarily focusing on vulnerabilities in purposes constructed on the community.
Blockaid mentioned code exploits dominated Ethereum incidents by rely, with main losses additionally linked to key compromises involving Humanity Protocol and StablR. CoWSwap, an Ethereum-based decentralized trade, was the one main Ethereum incident within the report labeled as a person mistake.

Blockaid recognized a number of frequent assault strategies focusing on Ethereum, together with bugs in bridges and good contracts, unauthorized entry to privileged accounts and market manipulation strategies.
The report mentioned Ethereum stays a significant goal as a result of it hosts most of the crypto business’s most respected purposes, together with restaking platforms, stablecoins and decentralized exchanges.
Solana losses surged as attackers shifted focus
Solana incurred practically as a lot in losses as Ethereum throughout the first half of 2026, a pointy improve from the roughly $127 million in stolen funds the community recorded throughout 2025.
“2025 had $2.58 billion misplaced throughout 63 incidents, concentrated in Q1 by Bybit’s $1.5 billion, with Ethereum and Arbitrum the highest chains by stolen-fund circulation,” Blockaid CEO Ido Ben-Natan instructed Cointelegraph.

The change didn’t stem from an increase in good contract exploits. As an alternative, compromised keys accounted for greater than 98% of Solana’s losses, pushed largely by incidents involving Drift Protocol and Step Finance, which Blockaid linked to North Korea-linked cyber teams.
Not like Ethereum, the place attackers primarily exploited vulnerabilities in protocol code, Solana incidents focused signer infrastructure and organizational safety, whereas a handful of code exploits involving Raydium and Volo accounted for the remaining losses.
