Active addresses peaked near 978,000 on July 31, about 1.6 times July\u2019s daily average, before settling into a still-elevated range of roughly 751,000 per day through the first week of August, versus a July average closer to 610,000.<\/p>\n<figure id=\"attachment_837817\" aria-describedby=\"caption-attachment-837817\" style=\"width:901px\" class=\"wp-caption aligncenter\"><figcaption id=\"caption-attachment-837817\" class=\"wp-caption-text\">Image source: Santiment<\/figcaption><\/figure>\n<p>What makes this spike different from a typical bull-market address boom is what\u2019s missing, i.e. buying. Exchange inflows over the same stretch averaged about $1.55 billion daily, actually slightly below July\u2019s $1.67 billion average. Wallets are multiplying and moving coins, but the money isn\u2019t piling into exchanges to trade. That divergence suggests defensive behavior.<\/p>\n<h2>Inside the Coldcard Flaw<\/h2>\n<p>The trigger traces back to Coinkite\u2019s Coldcard hardware wallets, where a firmware bug (first introduced in a March 2021 build across versions 4.0.1 through 4.1.9) routed seed-phrase generation through a software random-number generator instead of the device\u2019s dedicated hardware entropy chip on affected Mk3 units.<\/p>\n<p>What should have been a 128-bit cryptographic key came out with roughly 40 bits of real randomness on the worst-affected devices, and around 72 bits on some later models. Bitcoin.com News has tracked the toll, with <a href=\"https:\/\/news.bitcoin.com\/featured\/bitcoin-64k-coldcard-losses-114m\/\">losses topping $116 million<\/a> and a fourth wave of thefts <a href=\"https:\/\/news.bitcoin.com\/security\/coldcard-hack-116-million-fourth-wave\/\">still draining wallets<\/a> days after the initial disclosure.<\/p>\n<h2>What the Data Actually Shows<\/h2>\n<p>As word spread that certain Coldcard Mk3, Mk4, Mk5 and Q devices running vulnerable firmware could have their seeds brute-forced, security-conscious holders had every reason to generate new wallets on unaffected hardware, sweep their coins to fresh addresses, and rotate away from any setup that might share the same weak-entropy flaw.<\/p>\n<p>That behavior alone can explain the spike in new and active wallets, paired with exchange inflows that never followed.<\/p>\n<p>Coinkite has since shipped a firmware fix and published an entropy hotfix disclosure detailing exactly how much randomness affected devices actually generated. Independent security researchers have also piled in with one emergency audit effort finding <a href=\"https:\/\/news.bitcoin.com\/security\/bitcoin-red-team-audit-coldcard-vulnerabilities\/\">nearly 5,000 separate vulnerabilities<\/a> across hundreds of bitcoin-adjacent projects in just over a day of testing.<\/p>\n<h2>Not a Protocol-Level Problem<\/h2>\n<p>Experts have been careful to draw a distinction between this incident and a flaw in bitcoin itself. The <a href=\"https:\/\/news.bitcoin.com\/security\/bitcoin-wasnt-hacked-in-coldcard-attack-pompliano-explains\/\">weakness sat entirely<\/a> in how one manufacturer\u2019s firmware generated randomness for seed phrases, a self-custody supply-chain failure rather than anything wrong with the blockchain.<\/p>\n<p>Geographic data added another wrinkle to the mix as researchers tracking victim wallets found <a href=\"https:\/\/news.bitcoin.com\/security\/canadian-users-account-for-25-of-coldcard-exploit-losses\/\">Canadian users account for roughly a quarter<\/a> of the exploit\u2019s losses, likely reflecting Coinkite\u2019s Canadian base and a concentrated early customer footprint there.<\/p>\n<p>Combined with reports that the exploit briefly <a href=\"https:\/\/news.bitcoin.com\/market-updates\/coldcard-exploit-fuels-market-fear-as-2-bitcoin-forks-loom-ahead\/\">fueled market anxiety around unrelated bitcoin fork proposals<\/a> circulating at the same time, the episode has become a case study in how a narrow, patchable firmware bug can still ripple into headline onchain metrics well beyond the affected device count.<\/p>\n<\/p><\/div>\n<p><a href=\"https:\/\/news.bitcoin.com\/featured\/bitcoin-new-wallets-2026-high-coldcard-hack\/\">Source link <\/a><br \/>\n<br \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(Originally posted on : Bitcoin News ) Key Takeaways Bitcoin logged 2.27 million new wallets and 751,000 active wallets, its strongest reading in months.
