LINE NEXT and Sega Join Hands to Develop Web3 Games with NFTs

Token Cat Limited, a Nasdaq-listed Chinese automotive marketplace formerly known as TuanChe Limited, has approved a new digital asset investment policy that will allow the company to deploy up to $1 billion into cryptocurrencies as part of its treasury strategy. In a press release distributed via Chainwire, the Beijing-headquartered company said its board of directors signed off on a Crypto Asset Investment Policy authorizing the use of a portion of its cash reserves to acquire selected tokens under internal risk-management controls. Any purchased assets will be held with third-party custodians rather than managed in-house, the company said.Photo by Precondo CA on UnsplashThe initial allocation will focus on tokens tied to newer projects in areas such as artificial intelligence, RAW-to-chain infrastructure, and token–equity hybrid models. Further deployments will be evaluated over time and will remain subject to additional board approval, according to the statement. The policy will be implemented under the oversight of Sav Persico, who was recently appointed chief operating officer. Token Cat said he brings decades of experience in technology and blockchain-related businesses and emphasized that the initiative reflects a long-term approach to digital assets rather than a speculative trade. China’s regulation and softer DAT inflowsToken Cat’s decision comes even as China’s central bank continues to stress that crypto-related business activity remains off-limits domestically. According to Reuters, the People’s Bank of China (PBOC) recently reiterated that services involving virtual assets constitute “illegal financial activities” and highlighted that cryptocurrencies do not have the legal status of fiat currency. The statement was issued against the backdrop of what the central bank characterized as a renewed pickup in speculative crypto trading and broader concerns about financial risks. Beyond China, Token Cat’s move fits into a wider trend of companies experimenting with so-called digital asset treasuries (DATs), in which companies commit varying portions of their balance sheets to crypto. Those strategies, however, have seen softer momentum in recent months. Cointelegraph, citing data from DefiLlama, reported that DATs drew about $1.32 billion in fresh capital in November, the lowest monthly intake of 2024. Bitcoin-focused DATs accounted for the bulk of that activity with roughly $1.06 billion of inflows, while Ethereum-based DATs saw about $37 million in outflows. Bitwise chief investment officer Matt Hougan said on X that DATs have generally moved in tandem over the past six months, but he expects that pattern to change as investors begin to differentiate between firms with clearly articulated strategies and those without. He said a limited number of DATs could emerge with more resilient valuations, while others may continue to trade at persistent discounts. Biotech Sonnet advances HYPE-token planDespite the recent slowdown in inflows, new corporate efforts to gain exposure to digital assets continue. One example is Sonnet BioTherapeutics Holdings, a North Carolina–based biotechnology company developing immuno-oncology drugs. On Dec. 2, Sonnet said its shareholders had approved a proposed business combination with Hyperliquid Strategies Inc. (HSI) and Rorschach I LLC. That vote followed an agreement reached in July for Sonnet to merge with Rorschach to form Hyperliquid Strategies, a new entity expected to hold roughly 12.6 million HYPE tokens valued at about $583 million, along with at least $305 million in cash, for a projected combined value of $888 million. Hyperliquid is a decentralized exchange (DEX) built on its own layer-1 blockchain. Its native token, HYPE, has a total supply of one billion and is used for network governance, staking, and smart contract functions on HyperEVM, the platform’s EVM-compatible environment. Sonnet’s move, together with Token Cat’s newly adopted investment policy, adds to a steady stream of corporate initiatives testing the role of digital assets in balance-sheet management. With companies ranging from biotech firms to automotive marketplaces exploring similar strategies, the coming months will show whether crypto holdings can establish themselves as durable components of corporate treasuries. 

Mixin Network Suspends Services Amid $200 Million HackOn Monday, Mixin Network, a decentralized peer-to-peer network whose project team is based in Hong Kong, officially confirmed a substantial security breach that resulted in the loss of approximately $200 million in crypto assets from its mainnet.Photo by GuerrillaBuzz on UnsplashSeptember 23 hackThis incident, disclosed via an X (formerly Twitter) post, prompted the immediate suspension of all deposit and withdrawal services on Mixin Network until further notice.The project team outlined that the hack occurred on September 23, exposing vulnerabilities that allowed malicious actors to compromise the database of a third-party cloud service provider. Mixin Network has taken action to address the situation, enlisting the expertise of Singapore-headquartered blockchain security investigator SlowMist and the support of Google to conduct a thorough investigation and formulate a recovery plan.At the time of the breach, Mixin Network’s holdings included $94.48 million in Ether, $23.55 million in Dai, and $23.3 million in Bitcoin, as reported in an independent investigation by PeckShield. The total value of assets affected amounted to $141.32 million.Cyvers, an Israeli Web3 security firm, has also been looking into the matter on Monday. In a social media post, the firm stated:”Our internal investigation has uncovered suspicious funding transactions involving @MixinKernel hacker addresses. Two of hacker addresses received 51 $ETH from 0x1795F0eBDa5A836aE63F28CE546E72de069A8bd2 who was interacted with @HuobiGlobal and @binance.”The firm goes on to call on Binance and its CEO Changpeng Zhao (CZ) and Huobi to help identify the wallet address in question.Halting withdrawalsIn response to the security breach, Mixin Network has temporarily halted all deposits and withdrawals on its platform. These services will only resume once the vulnerabilities have been identified and fully resolved. On X, the project stated:”Deposit and withdrawal services on Mixin Network have been temporarily suspended. After discussion and consensus among all nodes, these services will be reopened once the vulnerabilities are confirmed and fixed. During this period, transfers are not affected.”Details regarding the plans to recover the lost assets for affected users have yet to be announced.Despite initial promises that Mixin Network’s Founder, Feng Xiaodong, would address the incident in a public Mandarin live stream on September 25, links to the live stream were not provided on the official social media channels or the website mixin.network.The incident has garnered criticism on the basis of a lack of decentralization. One commentator stated:”Some of those blockchain protocols are so decentralized that when their cloud database is hacked, coins are also gone.”Ongoing hacksThis security breach on Mixin Network is the latest in a series of high-profile crypto-related incidents. Ethereum Co-Founder Vitalik Buterin recently fell victim to a SIM swap attack, which resulted in the compromise of his X (formerly Twitter) account.In a statement, Buterin revealed that the hackers had successfully executed a SIM swap, a type of attack that targets the victim’s mobile phone number to gain unauthorized access to various online accounts, including social media, banking, and cryptocurrency platforms.The repercussions of the Mixin Network hack underscore the ongoing challenges faced by the crypto industry in ensuring the security and protection of digital assets. As investigations continue, affected users await further developments and the eventual resumption of deposit and withdrawal services.

Korea Investment and Securities Completes the Construction of Security Token InfrastructureKorea Investment and Securities (KIS) recently announced that it has become the first securities firm in South Korea to successfully establish an infrastructure for security token offerings.Photo by Joshua Sortino on UnsplashReal-world assetsSecurity tokens are a new class of securities that are based on distributed ledger technology, allowing individuals to invest in real-world assets (RWAs) that can be tokenized. Such assets include real estate, ships, airplanes, and artworks.In March, KIS initiated a security token consortium named “Korea Investment ST Friends,” collaborating with Internet-only banks KakaoBank and Toss Bank, AI company Kakao Enterprise, and blockchain developer Open Asset. Since May, the consortium has been diligently working with the principal objective of constructing an infrastructure leveraging distributed ledgers. Consequently, the group has finalized the development and testing of a system that manages the entire trajectory of security token projects, from issuance to liquidation.Cloud systemSpecifically, KIS has built its infrastructure on a cloud network, bearing in mind that the regulatory framework for security tokens is still in development. This cloud system is capable of adapting to regulatory modifications and implementing improvement updates. Moreover, it utilizes an agile development approach to encourage rapid decision-making and productive collaborations, enhancing time efficiency.Compatibility with the traditional systemThe newly established security token infrastructure is also compatible with the traditional security trading system. Achieving this compatibility posed numerous technical challenges as the new system operates on distributed ledgers, whereas the existing one relies on centralized servers.KIS is preparing to file patents for some of the technologies incorporated into the new system. These technologies encompass the payment of dividends through smart contracts, assurance of immediate settlements using deposits on distributed ledgers, and the management and safeguarding of personal information. By demonstrating the infrastructure’s capability and stability, the securities firm aims to gain a technological edge.Choi Seo-ryong, the head of the platform division at KIS, expects the new infrastructure to mark a significant milestone as distributed ledger technology merges with traditional finance. He further mentioned that the securities company will discover blue-chip assets meeting investor needs while committing to the stable establishment of the regulatory framework and the protection of investors.Moving forward, ST Friends will continue to enhance the stability and functionalities of the infrastructure through a series of field tests related to the entire process of security token products. Aiming to construct a security token ecosystem, the group will also concentrate on developing products by collaborating with various firms, including Korean content investment platform Funderful and real estate trading platform Valuemap.
