Crypto security losses reached $1.1 billion in the first half of 2026, according to a report from blockchain security firm Blockaid, underscoring the scale of exploits, thefts, and attacks that hit the industry through midyear.
The figure covers H1 2026, the six-month stretch from January through June, rather than any single incident. Blockaid, whose work spans wallet and transaction security, published the loss total as part of its assessment of the crypto threat landscape, with the company's focus outlined on its official site.

The reported total also appeared in Blockaid's written submission to the SEC, tying the security data to regulatory engagement rather than a standalone marketing report. For related coverage, see Bitcoin Trading Volume Falls More Than 75% From Late-2024 Peak.
The half-year losses coincided with a record volume of attacks, with 212 exploits recorded in H1 2026, a new high for a first half.
An aggregate loss of this size typically reflects multiple attack vectors rather than one breach. Common categories in crypto security incidents include wallet compromises, smart contract exploits, phishing, and front-end attacks, though the brief does not attribute the total to any single one of these.
Blockaid shared findings from the period through its account on X, where the firm posts security research and threat updates.

Large aggregate losses weigh on user trust and push security and compliance higher on the priority list for platforms handling customer funds. A record exploit count reinforces that pressure across the market.
The relevance extends to centralized exchanges, DeFi protocols, and NFT participants, all of which depend on wallet and transaction integrity. The stakes are visible in a market where Ethereum has topped 200 million non-empty wallets, expanding the surface that attackers can target.
Institutional exposure adds another dimension, as products like Morgan Stanley's Ethereum and Solana trusts bring regulated investors closer to assets whose underlying security still depends on the same threat landscape. Meanwhile, growth in leveraged venues, such as TradFi crypto perpetual open interest doubling to $2 billion, raises the value at risk if platform security fails.
With the H1 figure and a record exploit count on record, security posture heading into the second half of 2026 becomes the metric to watch for exchanges and protocols alike.
