Galaxy Digital Head of Research Alex Thorn stated that based on new victim reports received following the incident, the number of attackers exploiting the Coldcard vulnerability has reached at least 15.Thorn noted that information provided by victims helped the research team uncover previously unidentified attack activity. Unlike thefts from centralized exchanges, correlations between the attackers in this vulnerability exploit require confirmation through on-chain analysis and victim feedback.He added that a single victim reporting less than 1 BTC stolen helped the team discover a previously unknown attack, which siphoned approximately 12 BTC from 126 addresses.According to Galaxy Research's earlier estimates, the Coldcard vulnerability has led to at least three rounds of attacks, with losses amounting to approximately $100 million in BTC. Additionally, Galaxy has identified a suspected fourth round of attacks, which could bring total losses to approximately $130 million.Meanwhile, the incident has also sparked discussions regarding the security of Bitcoin self-custody. Dragonfly Managing Partner Haseeb Qureshi stated that "AI security hardening costing around $2" could potentially have prevented this vulnerability, and noted that some AI models were able to rediscover related vulnerabilities within a relatively short timeframe. However, industry insiders pointed out that current claims about the speed of AI discovering vulnerabilities lack rigorous blind testing and verification.Researchers believe that as AI model capabilities improve, the costs of vulnerability discovery and attacks in the crypto industry may continue to decline, requiring wallet developers to further strengthen code audits and security protections.

Odaily News: Michael Saylor stated on the X platform that at block height 961,022, BIP-110 received 38 signals, accounting for 2.70%, making its 55% voluntary threshold unreachable. At block height 961,632, BIP-110 nodes will reject blocks that do not emit signals. Unless major miners change their stance, Bitcoin will continue to operate normally, while BIP-110 will stall or fork into an insignificant state. Its supporters should stop pushing forward.

: Evan Cheng, co-founder of Mysten Labs, the development entity behind Sui, stated that within the next four years, the scale of digital payments carried by Sui will be comparable to the combined scale of traditional internet bank card networks and bank payment rails. Mysten Labs was founded in 2021 by engineers who previously worked on Meta's discontinued Diem blockchain and the Move programming language. Cheng positions Sui as settlement infrastructure for stablecoins, remittances, and agent-to-agent commerce between AI systems. Since June 10, when Mysten Labs removed gas fees for stablecoin transfers at the protocol level, Sui has processed over $65 billion in stablecoin transfers. Since the beginning of 2024, Sui's cumulative stablecoin transaction volume has reached $2.27 trillion. Sui's Hashi testnet went live on July 22, allowing Bitcoin to be used as collateral for decentralized finance loans on Sui without being wrapped as a synthetic token. The bridge was built by Mysten Labs and the Sui Foundation in collaboration with more than 20 participating institutions.
According to the market weekly report released by market maker Wintermute (@wintermute_t), the macro and crypto markets experienced multiple shocks over the past week: On the macro level, the Federal Reserve maintained interest rates unchanged at 3.50-3.75% with a 9-3 vote. Officials Hammack, Kashkari, and Logan rarely voted together to support a 25bp rate hike, marking dissent at the second meeting since Chairman Warsh took office. The 30-year US Treasury yield once touched 5.24%, hitting a new high since July 2007, while the 10-year yielded 4.67%. The yield curve bear-steepened, indicating market doubts about the Federal Reserve's inflation credibility. On the stock market level, AI leveraged fund Situational Awareness (under Leopold Aschenbrenner) encountered margin calls due to leverage as high as 400%. Its size plummeted from $45 billion in early July to about $10 billion, forced to sell all public positions to Citadel at a discount. Long positions in AI infrastructure such as SK Hynix and CoreWeave fell sharply, partially explaining the reason for the continuous decline in chip stocks in July. On the crypto level, BTC fell 2.84% weekly and ETH fell 3.63% weekly, but Wintermute believes major sellers are nearly exhausted, and the painful trade direction has turned upward. ETH has outperformed BTC for two consecutive months,
Odaily News: Hardware wallet manufacturers Trezor and Foundation have warned that following the disclosure of a Coldcard firmware vulnerability, phishing attempts targeting hardware wallet holders have increased, with attackers soliciting recovery phrases and luring victims into downloading malware. Security firm Proofpoint has detected phishing emails impersonating Coldcard, inviting users to complete a "hardware audit" with links to a cloned website. After clicking, users download a batch file hosted on GitHub that installs the remote access tool ScreenConnect. Proofpoint stated that the fraudulent website also features a customer service chat window, where real people guide victims through the installation process. This remote access tool can provide attackers with a pathway to steal data and funds, or further deploy malicious programs such as ransomware. Galaxy Research has confirmed three rounds of theft since July 30, with high-confidence losses of 1,596 BTC, exceeding $100 million; if a fourth round not yet confirmed with victims is included, total losses could reach $130 million.
According to the official announcement, Upbit will list QUID KRW, BTC, and USDT trading pairs.
According to Bitcoin.com, Fireblocks released the 2026 "Financial Grid" survey report, covering over 600 executives. The report shows that 99% of Continental European institutions and 100% of UK institutions expect regulatory policies to support digital asset development. Influenced by the clarity of the MiCA regulatory framework, 53% of European institutions have completed capital commitments before 2026, higher than the global average of 42%; as the UK's regulatory framework is still being formulated, this proportion is only 36%, but an additional 59% of UK institutions plan to complete budget allocations within 2026. In terms of product strategy, European institutions lead in tokenized money market funds (62% vs 45%) and tokenized securities; the UK is more aggressive in stablecoin issuance, with 50% of institutions planning to issue stablecoins independently, higher than Europe's 40%. Both markets list 24/7 settlement and real-time payments as primary application scenarios.
Odaily Planet Daily Report: Bitcoin hardware wallet manufacturer Coinkite disclosed in late July 2026 that a firmware build error introduced in March 2021 caused some Coldcard wallets to generate mnemonics from a smaller range, reducing the randomness of user private keys. Galaxy Research analysts stated that the Coldcard exploit occurred in multiple rounds, with observed Bitcoin losses rising from approximately $88 million to nearly $114 million within days. Researchers warned that other vulnerable addresses could still become targets, prompting many Coldcard users to move their Bitcoin. Coldcard is a Bitcoin-only wallet that supports offline signing via microSD card and optional QR codes. Launched in 2017, it has long been regarded as one of the security-focused Bitcoin hardware wallets.
Odaily News: Bitcoin News posted on X platform, stating that Boltzhq has indefinitely suspended its swap service after reporting an increase in AI-assisted attacks and multiple contained exploits. Due to its non-custodial design, user funds were never at risk, but wallets relying on Boltz for Lightning Network swaps, including AquaBitcoin and BULLBITCOIN, experienced service disruptions while alternative infrastructure is being deployed.

Odaily News: Bitcoin wallet service provider Nunchuk has issued an important update regarding the recent Coldcard security incident, recommending that users with multisig wallets containing Coldcard-generated keys migrate their funds as soon as possible.Nunchuk has categorized response levels based on the number of affected Coldcard keys in a multisig wallet: if the number of Coldcard-generated keys has reached the signing threshold, attackers could theoretically transfer funds directly, and such users should migrate immediately; if the wallet contains only 1 Coldcard-generated key and it is below the signing threshold, a single compromised key cannot move funds independently, making the risk relatively lower, but migration is still strongly recommended. If users cannot confirm the exact number of Coldcard keys in their wallet, they should treat it as a high-risk situation.Additionally, Nunchuk announced that an upcoming mobile update will automatically enable the Slipstream channel for paid users. At that point, any auxiliary multisig wallet transaction containing at least one Coldcard key will bypass the public mempool and be submitted via Slipstream, reducing the risk of transaction monitoring and replacement. For users who wish to act immediately or for free-tier users, Nunchuk offers a manual migration option: users need to create a migration transaction, complete multisig signing without broadcasting, and then submit the raw transaction data to the Slipstream platform.
According to PR Newswire, AI data center company Hyperscale Data (NYSE: GPUS) announced the successful implementation of a Bitcoin-backed DeFi financing strategy via the Morpho protocol. As of August 2, 2026, the company has completed approximately $30 million in Bitcoin-collateralized borrowing through the protocol, with a current variable interest rate of approximately 4.9%. The raised funds will be used to support the continued construction of its Michigan AI data center campus, as well as general corporate purposes such as daily working capital. The company stated that this move aims to transform its Bitcoin treasury from a passive reserve asset into a source of low-cost growth capital, while retaining exposure to Bitcoin's long-term appreciation and reducing reliance on dilutive equity financing.
According to Cointelegraph, Coinkite, the manufacturer of Coldcard hardware wallets, disclosed that its devices have contained a random number generator (RNG) vulnerability persisting for up to five years since March 2021. The vulnerability stemmed from a firmware upgrade that mistakenly routed wallet seed generation to a less secure MicroPython pseudo-random number generator (PRNG), rather than the originally designed true random number generator (TRNG). Since code reviews only verified the existence of TRNG code without confirming whether it was actually invoked, the vulnerability remained undetected for a long period. To date, over 4,500 addresses have been compromised, with nearly $90 million worth of Bitcoin stolen. Kraken Chief Security Officer Nick Percoco stated that this incident should serve as a "wake-up call" for the hardware wallet industry, calling for the introduction of independent third-party testing mechanisms to mandate verification of whether the entropy sources actually invoked by production firmware are certified. Coinkite has suspended all device shipments and destroyed affected inventory after confirming the vulnerability, and stated it will cooperate with law enforcement agencies across multiple countries to trace the responsible parties.
According to Bitcoin.com, a recent survey report released by Bearingpoint shows that 23% of Swiss adults use cryptocurrency at least occasionally, far higher than 11% in Germany and 18% in Austria. The survey was conducted by YouGov in June 2026 among over 4,000 adults in Germany, Austria, and Switzerland. The report points out that Switzerland's leading advantage stems from its Distributed Ledger Technology Act (DLT Act) officially effective in 2021, which provides a clear legal framework for crypto assets, attracting a large number of enterprises to establish operations, and driving the expansion of the "Crypto Valley" ecosystem to 1,749 blockchain companies. Additionally, 37% of Swiss respondents consider cryptocurrency an asset worth investing in, and 45% support it becoming an international reserve currency, both leading Germany and Austria. In contrast, regarding Germany, although retail adoption rates lag behind, the "meinkrypto" platform under DZ Bank and Dekabank's crypto services for the savings bank network are expected to cover approximately 80 million customers, potentially gradually narrowing the gap with Switzerland.
According to CoinDesk, Strategy founder Michael Saylor announced that the company has launched the Bitcoin 200-week moving average (200W MA) and its premium/discount tracking feature on its official website.

Odaily News – On July 30, the minority staff of the U.S. Senate Committee on Banking, Housing, and Urban Affairs released a new analysis raising Democratic objections to the amended draft of the CLARITY Act. The analysis states that Donald Trump’s 2025 crypto revenue amounts to approximately $1.4 billion, and that current ethics provisions still allow him to retain related business arrangements. The analysis reviews World Liberty Financial, the TRUMP meme coin, cryptocurrency investments, staking income, and other business activities, concluding that provisions restricting officials from issuing or sponsoring digital assets would not materially affect the aforementioned financial arrangements. Staff estimated approximately $799 million in revenue related to World Liberty Financial and approximately $635 million from the TRUMP meme coin. Trump’s annual financial disclosure report lists $635.1 million in royalties from a licensing agreement with CIC Digital LLC related to Celebration Coins, along with Bitcoin and Ethereum wallets each valued at over $50 million, and validator rewards obtained through staking agreements on Coinbase. The Senate draft of the CLARITY Act seeks to prohibit covered officials and their spouses from issuing or sponsoring digital assets for compensation during specified periods, while also establishing exceptions for qualified blind trusts, unauthorized third-party activities, continued use of an official’s likeness, and holding digital asset investments.
: Bitgo CEO Mike Belshe deposited 100 BTC into a public Bitcoin address on August 1, worth approximately $6.3 million at the time, and invited Anthropic's Claude model to attempt to move the funds out of the address. On-chain records show the wallet received the funds on July 31, and the balance had not been transferred out as of August 2. Anthropic previously disclosed that during 141,006 cybersecurity assessment runs, 3 incidents were found, with 6 evaluation sessions involving 3 models inadvertently interacting with real organizational systems. The models involved include Claude Opus 4.7, Claude Mythos 5, and an unreleased internal research model. The cause was a configuration error by third-party testing partner Irregular, which led to the test environment being connected to the internet. Anthropic stated that Claude Opus 4.7, during one evaluation, located a real website with the same name as a simulated company, exploited weak passwords and exposed services to recover infrastructure credentials, and accessed a production database containing hundreds of records. The company said the model was attempting to complete assigned tasks, not actively breaking constraints or pursuing independent goals. Belshe's challenge involves Bitgo's institutional custody platform, which uses multi-signature or multi-party computation technology to distribute signing authority across multiple independent keys. As of August 2, Anthropic had not publicly responded to the challenge.
