Crypto theft losses totaled $76 million in June, a 7% month-over-month decline, according to blockchain security firm PeckShield's monthly tracker published by The Block. The largest single exploit of the period targeted Humanity Protocol, the firm said.

The $76 million figure places June in the lower band of monthly readings since the start of 2025. Monthly totals have ranged from below $100 million in quiet periods to more than $300 million when a major exchange or cross-chain bridge breach occurs. June sits closer to the floor than the ceiling of that range.

What does the tracker actually measure?

The monthly figures count only on-chain, externally observable theft. Off-chain fraud, traditional phishing, and rugpulls involving tokens that never reached a public chain are excluded. By design, the headline number functions as a floor on industry-wide theft, not a comprehensive tally.

The methodology covers three principal categories of on-chain losses:

• Smart-contract exploits, including reentrancy, logic bugs, and access-control failures
• Cross-chain bridge or messaging failures, the historical source of several record-setting incidents
• Private-key or operator-compromise drains from protocol-controlled wallets

Why did June's losses decline?

A small number of marquee incidents typically account for the majority of any month's losses. June's 7% drop suggests none of the multi-hundred-million-dollar breaches that defined prior reporting periods occurred during the window. The composition — weighted toward mid-tier protocol exploits — produced a smoother headline number but does not on its own indicate reduced attacker activity across the period.

Where does Humanity Protocol sit?

Humanity Protocol operates in the proof-of-humanity and decentralized identity space, a category that has accumulated treasury capital ahead of token launches and mainnet deployments. The project became the top single target of the month per PeckShield's summary. Audit firms have repeatedly flagged decentralized identity contracts in 2025 as risk surfaces, particularly around sybil-resistance modules and credential verification flows.

What changes in the July reading?

PeckShield will publish July figures in early August. The trajectory of on-chain losses through the second half of 2025 will move with whether a major bridge or exchange exploit occurs; a single high-value breach can shift the monthly total by an order of magnitude and reset year-to-date comparisons. Private-key compromises and cross-chain bridge failures have remained the two highest-loss vectors across the past 12 months of reporting, and that pattern is unlikely to shift without coordinated defensive action across the operator teams that hold bridge validators and protocol treasuries.
