85 Critical Vulnerabilities Found Across the Bitcoin Ecosystem

85 Critical Vulnerabilities Found Across the Bitcoin Ecosystem

<p class="text-left mb-4 ">A large-scale security review of the Bitcoin ecosystem uncovered thousands of potential software vulnerabilities in just 27.5 hours. A volunteer team reported 4,962 findings across 390 <a href="https://jrkripto.com/tr/coin/btc" target="_blank" rel="noreferrer" class="text-primary underline">Bitcoin </a>projects, including 85 classified as critical.</p><p class="text-left mb-4 "> <figure class="my-6"> <img src="https://minio-api-1.jrkripto.com/blog/ekran-g-r-nt-s-2026-08-06-191243-6ac225ea.webp" alt="Ekran görüntüsü 2026-08-06 191243.png" width="auto" height="auto" class="w-full rounded-lg border" /> </figure> </p><p class="text-left mb-4 ">According to data shared by Calle, the pseudonymous developer behind the Cashu e-cash protocol, 16 Bitcoin developers participated in the review. The team used artificial intelligence models to examine the code of Bitcoin wallets, cryptographic libraries and infrastructure software.</p><p class="text-left mb-4 ">Calle described the situation as “extremely bad.” In addition to the 85 critical vulnerabilities, the findings included 635 issues classified as high severity.</p><p class="text-left mb-4 ">These figures do not mean that thousands of vulnerabilities were found directly in Bitcoin’s core protocol. The review covered open-source wallets, tools and various infrastructure projects connected to Bitcoin.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">Critical vulnerabilities reported to project owners</h2><p class="text-left mb-4 ">According to Calle, the team is privately disclosing critical findings to the developers responsible for the affected projects instead of releasing them publicly. Project owners quickly verified most of the critical reports.</p><p class="text-left mb-4 ">Before submitting a report, the developers also attempt to reproduce each vulnerability in a local testing environment using a working proof of concept. This process helps filter out inaccurate AI-generated results and provides project teams with findings they can independently verify.</p><p class="text-left mb-4 ">However, the large number of reports generated within such a short period has created another problem. Calle said the ecosystem was experiencing considerable chaos, with project maintainers struggling to process the volume of submissions.</p><p class="text-left mb-4 ">The team does not yet operate a fully automated system. A significant portion of the review still requires human guidance, while developers continue to improve the automated testing infrastructure.</p><p class="text-left mb-4 ">Calle said allowing team members to use their preferred review methods has proved to be the most effective approach so far. The AI models can therefore operate with different testing methods, while developers assess whether the generated reports point to genuine security vulnerabilities.</p><p class="text-left mb-4 ">Rob Hamilton, who is developing the team’s automated review infrastructure, said identifying software vulnerabilities was no longer the main challenge. According to Hamilton, the hardest part is delivering reports to the correct project maintainers and coordinating the remediation process.</p><p class="text-left mb-4 ">The review comes as the Bitcoin ecosystem continues to deal with the consequences of a vulnerability affecting Coldcard hardware wallets. Attacks linked to a software flaw dating back to 2021 have reportedly resulted in the theft of as much as $114 million worth of Bitcoin since July 30.</p><p class="text-left mb-4 ">The attackers involved in the Coldcard incident did not need physical access to the affected devices. A flaw in the firmware made the key space associated with generated seed phrases predictable, allowing the attackers to remotely transfer funds from vulnerable wallets.</p>

Hyperliquid ETF Inflows Stall as JPMorgan Warns of Rising Competition

Hyperliquid ETF Inflows Stall as JPMorgan Warns of Rising Competition

<p class="text-left mb-4 ">Wall Street giant JPMorgan reported that strong inflows into Hyperliquid (HYPE) exchange-traded funds (ETFs) in May and June have nearly come to a complete halt since July. According to the bank, the slowdown reflects growing concerns about the protocol’s competitive position.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">Sharp decline after the May-June peak</h2><p class="text-left mb-4 ">According to JPMorgan’s report, Hyperliquid ETFs outperformed all non-Bitcoin crypto funds in May and June when inflows were measured relative to assets under management. However, this momentum largely disappeared in July and early August.</p><p class="text-left mb-4 ">In a report published on Thursday, JPMorgan analysts led by Nikolaos Panigirtzoglou said decentralized platforms such as Hyperliquid face significant challenges to their market share.</p><p class="text-left mb-4 ">Hyperliquid became one of the most closely watched crypto stories of the year as the value of its HYPE token rose rapidly. Investors showed strong interest in the protocol’s decentralized perpetual futures exchange.</p><p class="text-left mb-4 ">This growth turned Hyperliquid into one of the largest crypto ecosystems outside Bitcoin and Ethereum. Institutional capital, corporate treasury buyers and ETF issuers all began directing funds toward the protocol.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">Competition from centralized exchanges intensifies</h2><p class="text-left mb-4 ">JPMorgan analysts said the cooling demand partly reflects growing competition between decentralized derivatives platforms and regulated centralized exchanges. The launch of regulated crypto futures products in the United States could draw trading volume away from offshore decentralized platforms such as Hyperliquid.</p><p class="text-left mb-4 ">These platforms continue to face uncertainty around licensing, regulatory compliance and investor protection. Regulated alternatives may therefore become more attractive to institutional investors seeking greater legal clarity.</p><p class="text-left mb-4 ">The analysts also highlighted intensifying competition in prediction markets, an area Hyperliquid is exploring as it seeks to expand beyond perpetual futures trading. This segment is particularly important because trading fees remain one of the main factors supporting the token’s value.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">HYPE ranks fourth among corporate crypto treasuries</h2><p class="text-left mb-4 ">JPMorgan described Hyperliquid as one of the crypto market’s standout performers this year. The bank also said HYPE has become the fourth-largest asset held by corporate crypto treasuries, behind Bitcoin, Ethereum and Solana.</p><p class="text-left mb-4 ">Bitcoin is currently trading at $64,893.33, while Ethereum stands at $1,916.12. <a href="https://jrkripto.com/tr/coin/hype" target="_blank" rel="noreferrer" class="text-primary underline">Hyperliquid</a>, meanwhile, is trading at $55.92 after falling around 2%.</p><p class="text-left mb-4 "> <figure class="my-6"> <img src="https://minio-api-1.jrkripto.com/blog/hypeusdt-2026-08-06-18-17-22-ab26bf15.webp" alt="HYPEUSDT_2026-08-06_18-17-22.png" width="auto" height="auto" class="w-full rounded-lg border" /> </figure> </p><p class="text-left mb-4 ">Despite its strong performance, JPMorgan said it remains unclear whether Hyperliquid can continue gaining market share against larger rivals such as Solana and XRP.</p><p class="text-left mb-4 ">The report also showed that Bitcoin and Ethereum continue to dominate the crypto ETF market. Bitcoin ETFs manage approximately $77 billion in assets, while Ether ETFs hold around $10 billion.</p><p class="text-left mb-4 ">By comparison, ETFs tied to other cryptocurrencies, including Solana, XRP and Hyperliquid, manage only $2 billion to $3 billion combined.</p><p class="text-left mb-4 ">The HYPE token has lost more than 3% over the past 24 hours and is currently trading at approximately $55.30.</p><p class="text-left mb-4 ">Institutional interest still appears strong, but the arrival of regulated products from centralized exchanges could make the coming months more challenging for decentralized platforms. It also remains uncertain whether Hyperliquid’s expansion into new areas such as prediction markets can offset this competitive pressure.</p>

Türkiye’s Capital Markets Board Moves to Block Access to 12 Crypto Websites

Türkiye’s Capital Markets Board Moves to Block Access to 12 Crypto Websites

<p class="text-left mb-4 ">Türkiye’s Capital Markets Board (SPK) has initiated proceedings to block access to 12 websites that it determined were providing unauthorized crypto asset services to users in the country. The list includes international crypto exchanges such as Toobit and Bit2Me, alongside lesser-known investment platforms.</p><p class="text-left mb-4 ">The SPK announced the decision in its weekly bulletin dated August 5, 2026. The regulator will initiate the necessary legal proceedings under Article 99/A of the Capital Markets Law to restrict access to the platforms.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">Toobit and Bit2Me are also on the list</h2><p class="text-left mb-4 ">The websites <a href="https://spk.gov.tr/data/6a7395628f95db1c20deaf20/2026-49.pdf" target="_blank" rel="noreferrer" class="text-primary underline">named </a>by the SPK include toobit.com, rainiks.pro, webtrader.ifc-f1nance.online, bit2me.com, app.bit2me.com and coinup.io.</p><p class="text-left mb-4 "> <figure class="my-6"> <img src="https://minio-api-1.jrkripto.com/blog/ekran-g-r-nt-s-2026-08-06-124444-55904092.webp" alt="Ekran görüntüsü 2026-08-06 124444.png" width="auto" height="auto" class="w-full rounded-lg border" /> </figure> </p><p class="text-left mb-4 ">The regulator issued the same decision for neroxinvest.com, alveon-ltd.com, limartu-ledthra.org, goartex.com, parabu.io and coinbalina.com. Bit2Me’s main website and app address were counted separately, bringing the total number of listed web addresses to 12.</p><p class="text-left mb-4 ">Some of the domains appear to belong to investment websites without a widely known corporate identity or a significant user base in Türkiye. However, Toobit and Bit2Me are among the international crypto platforms operating across multiple countries.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">The decision does not constitute a fraud finding</h2><p class="text-left mb-4 ">The SPK’s decision does not mean that every website on the list has committed fraud. The regulator did not describe the platforms as scams or accuse them of fraudulent activity in its bulletin.</p><p class="text-left mb-4 ">The stated reason for the action is that the platforms allegedly provided crypto asset services to Türkiye-based users without authorization from the SPK. Therefore, lesser-known websites that may appear suspicious can be listed alongside established international exchanges under the same regulatory grounds.</p><p class="text-left mb-4 ">Under Türkiye’s regulations, a foreign platform may be considered to target users in the country if it creates a Turkish-language website, promotes its services directly in Türkiye or conducts marketing activities through Türkiye-based individuals or organizations.</p><p class="text-left mb-4 ">The decision comes as Türkiye tightens its oversight of unauthorized foreign platforms operating in its crypto market. <a href="https://jrkripto.com/tr/analytics" target="_blank" rel="noreferrer" class="text-primary underline">Crypto </a>asset service providers came under the SPK’s supervision in 2024, while secondary regulations introduced in 2025 established detailed requirements covering capital, custody, asset listings and the protection of customer funds.</p><p class="text-left mb-4 ">The latest bulletin indicates that the regulator has begun applying this framework not only to domestic companies but also to foreign platforms targeting users in Türkiye, gradually expanding the scope of its enforcement.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">Users should monitor the process closely</h2><p class="text-left mb-4 ">The publication of the websites in the bulletin does not mean that access was immediately blocked. At this stage, the SPK has decided to initiate the legal proceedings required to enforce the restrictions.</p><p class="text-left mb-4 ">The accessibility of the platforms, withdrawals and the availability of their mobile applications will now become key issues for account holders. Users may need to review their accounts, open positions and custody arrangements before any potential access restrictions take effect.</p>

Visa and Mastercard Step Up Stablecoin Competition

Visa and Mastercard Step Up Stablecoin Competition

<p class="text-left mb-4 ">Visa and Mastercard, two of the world’s largest payment companies, announced separate partnerships on the same day to expand their <a href="https://jrkripto.com/tr/category/stablecoins" target="_blank" rel="noreferrer" class="text-primary underline">stablecoin </a>infrastructure. Visa is integrating zerohash technology into the Visa Direct network, while Mastercard has launched a new pilot aimed at improving trust and compliance in cross-border stablecoin payments.</p><p class="text-left mb-4 ">The two initiatives focus on different areas. Visa is expanding stablecoin funding and payout capabilities, while Mastercard aims to verify participants in blockchain transactions.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">Visa Direct Opens Up to Stablecoin Payments</h2><p class="text-left mb-4 ">Visa will expand the stablecoin capabilities of Visa Direct through a collaboration with blockchain infrastructure provider zerohash. Eligible Visa Direct clients will be able to prefund merchant accounts with stablecoins and send stablecoin-denominated payouts to recipients.</p><p class="text-left mb-4 ">zerohash will provide both the technical infrastructure and regulatory compliance support for the service. However, the companies have yet to disclose which stablecoins and blockchain networks will be supported or where the service will initially become available.</p><p class="text-left mb-4 ">Visa Direct connects to more than 18 billion endpoints across over 195 countries and territories, including cards, bank accounts and digital wallets. The integration could therefore bring stablecoin-based payments to a broader group of institutional clients.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">Mastercard Focuses on Trust and Compliance</h2><p class="text-left mb-4 ">Mastercard, meanwhile, has launched a Crypto Credential pilot with Borderless.xyz. The companies will test Mastercard’s existing framework to verify participants and standardize compliance checks in cross-border stablecoin transactions.</p><p class="text-left mb-4 ">Crypto Credential generates assurance signals confirming that institutions involved in blockchain transactions meet specific security and compliance standards. Companies participating in the Borderless.xyz network will be able to incorporate these signals into transaction approvals, risk management and compliance procedures.</p><p class="text-left mb-4 ">Infinia, Walapay and Koywe are among the first stablecoin payment companies to join the pilot. Borderless.xyz says its infrastructure connects more than 15 licensed stablecoin providers across over 100 countries.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">Stablecoin Payments Race Accelerates</h2><p class="text-left mb-4 ">Visa’s initiative aims to simplify stablecoin funding and transfers, while Mastercard is strengthening the trust and identity verification layer surrounding these transactions. The two payment giants are therefore addressing different challenges within the stablecoin market.</p><p class="text-left mb-4 ">Mastercard recently completed its acquisition of stablecoin infrastructure company BVNK. Visa, meanwhile, introduced the Visa Stablecoin Platform in July, enabling financial institutions to issue, manage and transfer stablecoins.</p><p class="text-left mb-4 ">The series of developments shows that stablecoins are becoming increasingly embedded in traditional payment networks. Visa and Mastercard are moving beyond crypto-linked cards, creating a place for stablecoins within the underlying infrastructure of cross-border money transfers.</p>

$2.4 Billion AI Coin Is Now a History as Founder Pulls Support

$2.4 Billion AI Coin Is Now a History as Founder Pulls Support

<p class="text-left mb-4 ">AI16Z, once at the center of the AI-focused cryptocurrency frenzy, has gone from a multibillion-dollar valuation to the brink of closure in just 19 months. Shaw Walters, founder of Eliza Labs, announced that the project was ending all support for its successor token, ELIZAOS, and told holders to sell their tokens.</p><p class="text-left mb-4 ">In an Aug. 4 post on X, Walters said ELIZAOS no longer had a future. The ElizaOS Foundation is winding down, while the team will no longer pursue token buybacks, supply reductions or other measures designed to support the price.</p><p class="text-left mb-4 "> <figure class="my-6"> <img src="https://minio-api-1.jrkripto.com/blog/ekran-g-r-nt-s-2026-08-05-161649-38602ed8.webp" alt="Ekran görüntüsü 2026-08-05 161649.png" width="auto" height="auto" class="w-full rounded-lg border" /> </figure> </p><p class="text-left mb-4 ">“The token is dead. Completely,” Walters wrote. He said he would continue developing the ElizaOS software but made it clear that he had no plans to launch another token to fund the project.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">ELIZAOS lost 97 percent of its value</h2><p class="text-left mb-4 ">Following the announcement, ELIZAOS traded near $0.00031, giving the token a market capitalization of approximately $2.3 million. That level represented a decline of roughly 97 percent from its peak.</p><p class="text-left mb-4 ">The project’s original token, AI16Z, reached a market capitalization of $2.39 billion on Jan. 2, 2025. Daily trading volume climbed to $291 million at the time, making AI16Z one of the largest cryptocurrencies in the AI token sector.</p><p class="text-left mb-4 ">The team later launched a migration that replaced <a href="https://jrkripto.com/tr/coin/ai16z" target="_blank" rel="noreferrer" class="text-primary underline">AI16Z </a>with ELIZAOS. Despite the transition, CoinGecko continues to list the abandoned AI16Z contract as a separate asset. Its market capitalization stood at around $375,000 in the early hours of Aug. 5.</p><p class="text-left mb-4 ">Walters said the tokens held in his personal wallet were once worth approximately $25 million. According to the founder, their value fell toward zero as the project encountered mounting problems and lost market confidence.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">Lawsuit drained the foundation’s treasury</h2><p class="text-left mb-4 ">A proposed class-action lawsuit played a decisive role in the closure of the ElizaOS Foundation. Walters said the foundation transferred its remaining tokens and available cash to settle with a group of holders represented by Burwick Law.</p><p class="text-left mb-4 ">Burwick Law filed the proposed class action in the U.S. District Court for the Southern District of New York in April. The plaintiffs raised allegations of false advertising, deceptive business practices, negligent misrepresentation and unjust enrichment.</p><p class="text-left mb-4 ">According to the complaint, the team marketed the project as an “autonomous, AI-managed venture fund.” The plaintiffs, however, alleged that Walters and other insiders retained control over the project and its investment decisions.</p><p class="text-left mb-4 ">The lawsuit also addressed the dilution of existing holders during the migration from AI16Z to ELIZAOS. The plaintiffs claimed that entities controlled by the project’s managers received 40 percent of the newly minted tokens.</p><p class="text-left mb-4 ">Walters described the holders’ claims as “ridiculous.” Still, he said the ElizaOS Foundation lacked the capital required to fight a prolonged legal battle and therefore chose to settle.</p><p class="text-left mb-4 ">The financial terms of the settlement remain undisclosed. Eliza Labs and Burwick Law have yet to provide detailed information about how much holders received or the current status of the federal case.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">The AI16Z name had also sparked controversy</h2><p class="text-left mb-4 ">The project launched on Solana under the AI16Z name in October 2024. The name was an apparent reference to “a16z,” the widely used abbreviation for Silicon Valley venture capital firm Andreessen Horowitz.</p><p class="text-left mb-4 ">Andreessen Horowitz objected to the use of the name, contributing to the project’s decision to rebrand as ElizaOS. Walters and his team later changed the token’s name to ELIZAOS and began moving holders to the new contract.</p><p class="text-left mb-4 ">The transition aimed to achieve more than resolving a branding dispute. The team also sought to emphasize its open-source ElizaOS AI agent framework and move the project away from its identity as a speculative token.</p><p class="text-left mb-4 ">However, falling prices, criticism of the token migration and the lawsuit disrupted that strategy. Walters argued that investors ignored the software tools developed by the team because the token’s price continued to decline.</p><h2 class="text-left text-foreground text-3xl font-bold mb-3 mt-1">The AI agent frenzy proved short-lived</h2><p class="text-left mb-4 ">AI16Z became one of the leading projects in the rapidly growing AI agent token category in late 2024. It attracted attention with a venture capital model in which token holders participated as partners while an AI agent supposedly made investment decisions.</p><p class="text-left mb-4 ">Truth Terminal and the GOAT token launched around it played an important role in the rise of this market narrative. GOAT reached a market capitalization of $1.2 billion within days of its October 2024 launch, fueling demand for tokens linked to AI agents.</p><p class="text-left mb-4 ">Projects such as Virtuals Protocol and AI16Z subsequently reached multibillion-dollar valuations. The sector promised to build a new crypto economy around software agents capable of controlling their own wallets, posting on social media and making independent decisions.</p><p class="text-left mb-4 ">The open-source ElizaOS software will continue operating despite the token’s collapse. ELIZAOS holders, meanwhile, have been left without foundation support, a buyback program or another migration plan.</p>
