Crypto security losses reached $1.1 billion in the first half of 2026, according to a report from blockchain security firm Blockaid, underscoring how a single half-year can absorb losses from a wide range of exploits, thefts, and attacks across the industry.

The figure covers H1 2026, the six-month period from January through June, and does not refer to a 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: . That filing tied the security data to regulatory engagement rather than presenting it as a standalone marketing report, making the loss figure part of a broader discussion about how digital-asset security is being tracked and reviewed.

Record exploit activity behind the losses

The half-year losses coincided with a record level 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, although Blockaid did not attribute the total to any single category.

Blockaid shared its findings from the period through its account on X:

Why the figure matters for the market

Large aggregate losses can weigh on user trust and push security and compliance higher on the priority list for platforms handling customer funds. A record exploit count adds to that pressure across the market, especially for systems that depend on uninterrupted wallet and transaction integrity.

The issue affects centralized exchanges, DeFi protocols, and NFT participants, all of which depend on wallet and transaction integrity. The stakes are notable in a market where Ethereum has topped 200 million non-empty wallets, expanding the surface attackers can target.

Institutional exposure adds another layer, 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. At the same time, growth in leveraged venues, including TradFi crypto perpetual open interest that doubled to $2 billion, raises the value at risk if platform security fails.

With the H1 loss figure and a record exploit count now on record, security posture in the second half of 2026 is likely to remain a key focus for exchanges and protocols as firms review controls, monitoring, and incident response.
