The privacy protocol Umbra has shut down its hosted frontend website to prevent attackers from using the protocol to transfer stolen funds from recent security incidents.Umbra stated that approximately $800,000 had been transferred through its protocol, but the protocol is only used to hide the identity of the recipient, and the related transactions can still be tracked on-chain. This measure comes after the Kelp protocol was attacked, resulting in losses exceeding $280 million. Umbra stated that it will restore frontend services once it is confirmed that asset recovery efforts are not affected, but it cannot prevent users from continuing to use the protocol through smart contracts or self-hosted frontends.

According to CoinDesk, the prediction market platform Kalshi is preparing to launch cryptocurrency trading in the United States, expanding beyond its core prediction market business. According to insiders, the platform plans to initially introduce perpetual contracts linked to cryptocurrencies like Bitcoin.This move will put Kalshi in more direct competition with cryptocurrency platforms like Coinbase. Coinbase currently does not offer true perpetual contracts in the U.S., but has launched "perpetual-like" futures contracts with long durations and has expressed intentions to introduce more advanced derivatives products within the U.S.Kalshi holds several licenses from the U.S. Commodity Futures Trading Commission (CFTC) and has recently been approved to offer margin trading, positioning it to enter the derivatives market. Insiders say the company expects to start with cryptocurrency-linked perpetual contracts and may expand this model to other asset classes in the future.Kalshi's competitor Polymarket also announced on X plans to launch perpetual futures on its platform, but did not disclose further details. A video in the tweet shows that users will be allowed to trade leveraged long and short positions on assets like gold, NVIDIA, BTC, AAPL, and indicates that registration will provide early access.

Bitcoin Core releases version 31. The main updates are as follows: improved Mempool logic, allowing nodes to more accurately assess the overall value of a set of related transactions to decide whether to retain, forward, or package them; ordinary transfer users are minimally affected, but users utilizing RBF, CPFP, the Lightning Network, complex wallets, or server-side wallets may experience changes in transaction acceptance/rejection behavior; enhanced privacy broadcasting features, supporting broadcasting sendrawtransaction via Tor/I2P, where the recipient cannot know the IP address and geographical location of the transaction initiator.

ChainCatcher reported live that Lennix Lai, the Global Chief Business Officer of OKX, delivered a keynote speech at the 2026 Hong Kong Web3 Carnival. He pointed out that AI Agents are changing the way users interact with wallets and blockchains. OKX is building a wallet operating system from scratch that serves not only human users but also AI Agents: On-chain OS.This system is built on the existing capabilities of the OKX wallet, which includes 1.2 billion API calls per day, over $300 million in daily trading volume, support for more than 60 chains, and aggregation of 500 DEXs. Users can issue commands in natural language, such as "automatically exchange to USDC when ETH drops below 2000," and the Agent will automatically track prices, compare quotes from different DEXs, route the optimal path, and execute the trade upon human confirmation.He emphasized that Agents also need to trade and pay each other, thus requiring an efficient and low-cost microtransaction settlement layer. OKX's Layer 2 network, X Layer, plays this role with zero gas fees and instant finality, and it supports the X402 payment protocol and on-chain Agent identity registration. He stated that future financial infrastructure will no longer serve only top professionals; an individual working with five different Agents can achieve results comparable to those of large institutional investment teams, which is the most significant meaning of AI in the cryptocurrency industry.

At the "Crypto 2026: From Cryptocurrency to Smart Economy" themed forum held in Hong Kong, Gongye Feng, co-founder and CEO of Monera Digital, delivered a keynote speech titled "AI Empowered Private Banking for the Smart Economy."Feng pointed out that what disappeared after 2022 was not the demand for digital assets, but the market's confidence in the ways capital could enter. Monera Digital positions itself as an AI private bank for the smart economy, with the core not being to use AI as traders, but to act as an accelerator, compressing the research, testing, and iteration cycles from months to days.He emphasized that risk control must be institutionalized rather than personalized. Monera has built four lines of defense: source constraints on exposure and collateral, automated clearing and margin management, complete segregation of client assets, and eliminating maturity mismatches while maintaining liquidity buffers. Additionally, AI plays the role of a 24/7 digital CRO, achieving a leap from passive monitoring to proactive warning.In terms of service model, Monera does not operate as a pure technology platform, but insists on "anti-AI illusion," where AI is responsible for optimization and efficiency, while trust, responsibility, and continuity of relationships are still borne by humans. Feng believes that the prerequisite for crypto assets to truly become configurable assets is to translate complexity into clear, continuous, and trustworthy private banking services.

Cryptocurrency exchange Kraken's parent company Payward announced that it will acquire 100% of the digital asset derivatives platform Bitnomial for up to $550 million (cash + stock). The transaction is expected to be completed in the first half of 2026, pending regulatory approval.Bitnomial is the first crypto-native platform to obtain all three U.S. derivatives licenses (designated contract market, derivatives clearing organization, and futures commission merchant). This acquisition will help Payward quickly gain a complete compliant derivatives infrastructure, significantly accelerating its expansion in the U.S. market. After the transaction is completed, Bitnomial's clearing and trading capabilities will be integrated with platforms such as Kraken and NinjaTrader, offering products like spot margin, perpetual contracts, and options to U.S. customers, and will be regulated by the CFTC.This acquisition will also expand Payward Services, allowing banks, fintech companies, and brokerages to access the U.S. compliant derivatives market through a single API. Industry insiders believe that with the market warming up and valuations recovering, merger and acquisition activities in the crypto industry are on the rise, as leading institutions are accelerating their transformation into comprehensive trading platforms for institutional clients by acquiring key capabilities such as compliance, custody, and derivatives.

According to Bloomberg, Flow Capital Partners plans to launch its $150 million private credit fund on a blockchain platform based in Singapore by the end of this month, becoming one of the first asset management firms in Asia to leverage the growing liquidity of stablecoins.The alternative asset management company headquartered in Hong Kong will provide its master fund through DigiFT Tech Pte. and plans to raise an additional $30 million through tokenized shares by the end of this year. The company's Chief Investment Officer Jacky Tian stated that the goal is to expand the fund, which was launched in June, to $250 million by the end of the year.

The Layer 1 blockchain Tempo, developed jointly by Stripe and Paradigm, has launched a privacy feature called Zones. This is a solution for running permissioned parallel blockchains, specifically designed for enterprise-level use cases that require higher confidentiality, such as payroll, fund management, and payment settlement.It is reported that Zones, as a parallel blockchain connected to the Tempo mainnet, provides a private execution environment where internal transactions remain confidential, but assets and funds are fully interoperable with Tempo L1, other Zones, deposit channels, and liquidity pools. Each Zone is managed by trusted entities such as financial institutions or infrastructure providers, allowing operators to view all activities within their environment and implement access controls, but they do not control the underlying assets.

The exchange Zonda stated that its cold wallet holding 4,503 bitcoins (worth approximately $334 million) is currently inaccessible.Zonda CEO Przemysław Kral issued a video statement claiming that the private key for the wallet was never handed over during the company's transition. The private key was supposed to be transferred by Zonda's founder and former CEO Sylwester Suszek, but Sylwester Suszek has been missing since 2022. Przemysław Kral denied allegations of misappropriating funds and stated that an unusual surge in withdrawal requests was triggered by negative media coverage. Zonda plans to take legal action against false statements and is committed to fulfilling its obligations to customers. The exchange was renamed from BitBay to Zonda in 2021.

According to Cointelegraph, after a recent rebound, Ethereum's price has stabilized above $2,300, with ETH futures open interest increasing to $25.4 billion, indicating a rise in demand for leveraged positions.Meanwhile, Ethereum spot ETFs listed in the U.S. have seen a net inflow of $248 million over the past 10 days, and Bitmine Immersion has also disclosed the purchase of $312 million worth of ETH. However, the funding rate for ETH perpetual contracts has failed to remain above 5% and has repeatedly fallen below 0, reflecting limited market confidence in this round of increases. Additionally, Ethereum's weekly DApp revenue has dropped from $24 million in early February to $11 million, and weakened network activity along with intensified competition among public chains may continue to affect ETH's trend.

XRP Ledger announced the integration of zero-knowledge infrastructure provider Boundless to support banks and asset management institutions in executing transactions on the public chain that balance privacy protection and compliance.According to reports, this solution can hide sensitive information such as transaction size, frequency, and counterparties, while still allowing regulatory agencies to conduct audits through selective disclosure and role-based access control, thus achieving a balance between privacy and compliance. This integration will support institutional scenarios such as cross-border B2B payments, fund and capital management, over-the-counter (OTC) trading, tokenized asset issuance, and on-chain trading and lending.Industry insiders believe that the contradiction between the transparency of public chains and the demand for privacy has always been a significant barrier to institutional adoption, and this solution aims to reduce the so-called "transparency tax." Meanwhile, competition in the privacy track continues to heat up. Technologies such as zero-knowledge proofs (ZK) and fully homomorphic encryption (FHE) are accelerating implementation, pushing privacy capabilities from optional features to underlying infrastructure. Data shows that the market size of tokenized assets has reached approximately $29.25 billion, with a monthly increase of about 7.9%.

According to Bloomberg, the Federal Reserve is inquiring in detail with major banks about their risk exposure in the private credit sector, due to a surge in fund redemptions and a continuous rise in non-performing loans. The Treasury is also simultaneously questioning the insurance industry to comprehensively assess the overall pressure on the $1.8 trillion private credit industry and the risks of its spillover into the financial system.BitMEX founder Arthur Hayes commented, "I hope the scale is large enough so that we can welcome money printing to save the market." Implicitly, if this regulatory assessment reveals systemic risks, it may force the Federal Reserve to restart easing and implement large-scale monetary expansion, which could benefit the cryptocurrency market.
