Coldcard Hardware Wallet Flaw Drains ~$70M BTC
Topic: Crypto,
Sources: CoinDesk, CoinTelegraph.
More than 1,000 BTC, valued at about $70 million, was swept from nearly 1,200 Coldcard wallets in a 41-minute window on July 30. Galaxy Research analysis shows the attacker reconstructed private keys offline via a firmware flaw that made seed generation enumerable rather than truly random, without ever accessing the physical devices. Losses nearly doubled initial reports as additional addresses were identified; funds remain unmoved in four addresses. Coinkite has issued warnings for affected models while noting newer devices are safer, and Binance founder CZ urged wallet diversification.
Hardware wallets are marketed as the gold standard for self-custody by isolating keys from internet-connected systems. The flaw stemmed from a build setting that bypassed the dedicated hardware RNG, falling back to a software substitute based on serial numbers and clock registers, collapsing the keyspace to roughly four billion possibilities on some models—computationally feasible to brute-force against the public blockchain. Victims cannot easily verify if their seeds were generated on vulnerable firmware.
This incident exposes a core tension in crypto security: the assumption that offline keys are unguessable versus the reality of implementation bugs. It may accelerate a shift toward ETFs and custodial solutions among retail holders wary of self-custody risks, even as the attack size remains smaller than major exchange hacks. Further waves remain possible if holders do not migrate funds promptly, and investigators have traced the operator via blockchain data provider logs.
Oil Surges on Hormuz Risks Amid Iran Tensions

Crude posted its biggest July gain in over 30 years as US-Iran conflict re-escalated, with WTI holding near $85 per barrel. A Qatari LNG tanker was struck while transiting the Strait of Hormuz, contributing to supply fears; Indian Oil made record spot crude purchases on Mideast disruptions. US sanctions targeted an Iran-linked bitcoin insurance scheme for Hormuz shipping. Gulf exports struggle to fully recover despite some traffic rebound.
The Strait of Hormuz remains a critical chokepoint for global oil and LNG flows. July’s volatility stemmed from strikes, vessel incidents, and broader Middle East risks, lifting inflation expectations even as central banks held rates steady. Energy markets decoupled sharply from equities.
Key uncertainties include whether diplomatic off-ramps or further military actions will dominate, and how sustained high oil prices feed into broader inflation and rate-path debates. Physical market tightness contrasts with earlier glut narratives, creating contradictions for demand forecasts into late 2026.
July Market Jolt: Tech Wreck, Bond Yield Spike, BTC Resilience

July delivered Nasdaq’s worst performance in 22 years and bonds’ largest yield spike since 2005, driven by oil-driven inflation fears and AI trade capitulation. Bitcoin held monthly gains near $63,000–$64,000 despite late selling, with spot ETFs ending the month in the green on $172 million net inflows (though YTD still negative). Analysts flag a choppy August as forced selling exhausts and rate-hike concerns linger.
The US-Iran flare-up and energy shock reversed consensus positions, pressuring growth stocks and momo trades while commodities catapulted. Crypto showed relative resilience amid the equity and fixed-income bloodbath, with Tether reporting $1.5 billion Q2 operating profit.
Tensions center on whether oil-driven inflation forces tighter policy longer, potentially capping risk assets, versus exhausted selling creating bounce setups. Uncertainties include Fed path clarity, AI sector stabilization, and whether crypto’s July hold signals decoupling or delayed correlation.
