Hack confirmed without further detail

"At approximately 1:26 p.m. on Friday, May 31, 2024, we detected an unauthorized leak of bitcoin from our wallet," the company stated, based on an English translation of its original statement in Japanese, which had been posted on the firm’s website. DMM Bitcoin is a subsidiary of DMM Group, which incorporates businesses covering a broad spectrum of activities including solar energy, gaming, 3D printers, FX, e-books and software.

 

The company has, as yet, not provided any further detail relative to the manner in which the hack occurred. Notwithstanding that, DMM Bitcoin did confirm that measures have been taken to prevent any repeat of the hack. Furthermore, the company outlined that a full investigation into the hack is ongoing right now.

 

Buy orders and leverage trades suspended

The company has moved to reassure platform users that their digital assets are fully guaranteed. It stated:

 

"Please rest assured that all of your bitcoin deposits will be fully guaranteed, as we will procure the equivalent amount of BTC that was leaked with support from our group companies." 

 

The exchange has taken the decision to temporarily suspend a number of activities, including spot trading buy orders and the opening of leveraged trading positions. A temporary halt has been imposed on crypto withdrawals while Japanese yen withdrawals are permitted, albeit that the exchange suggests that service users may experience delays.

 

Blockchain security sector response

In light of the hack, a number of well-known blockchain security firms have been giving the matter their attention. Beosin, a blockchain security specialist, outlined that it is continuing to monitor the wallet addresses implicated in the hack, with a view towards tracing any further movement of the funds.

 

Meanwhile, blockchain analysis firm Arkham Intelligence has offered a 1,000 ARKM token bounty to anyone who may provide information leading to the identification of the perpetrators of the hack. Blockchain analysis firm Chainalysis described the hack as “the 7th largest crypto hack ever.” The company has labeled the stolen funds within its products.

 

Broader industry implications and historical context

This hack is a significant blow to the industry, given that a hack on this scale has not occurred thus far in 2024 or at any point during 2023.

 

The crypto industry has faced numerous significant breaches in the past. In 2022, a series of large-scale exploits targeted layer-1 blockchains, crypto exchanges and DeFi protocols. The largest hack amongst them implicated the BNB Chain (formerly Binance Smart Chain), which resulted in the loss of $566 million worth of BNB.

 

The latest hack is second only (within Japan) in size relative to the 2018 hack of Coincheck, one of the country’s largest exchanges, when over $550 million worth of XEM was stolen. Japan was also host to the most infamous Bitcoin hack, that of the Mt. Gox exchange, whose bankruptcy administrators moved $9 billion worth of its remaining Bitcoin holdings on the blockchain in recent days for the first time in many years.

Hong Kong and Israel Collaborate to Expand CBDC Access Beyond Banks

Hong Kong and Israel Collaborate to Expand CBDC Access Beyond BanksIn a collaborative effort, the Hong Kong Monetary Authority (HKMA), the Bank of Israel (BoI), and the Bank of International Settlements (BIS) Innovation Hub have jointly released a comprehensive report on Project Sela, a central bank digital currency (CBDC) initiative.Photo by POURIA 🦋 on UnsplashBroadening the role of intermediariesThe report was published to the BIS website on Tuesday. In keeping with the trend of many CBDC projects, Project Sela is characterized by a robust public-private partnership. However, its particular focus lies in broadening the spectrum of intermediaries, aiming to offer retail CBDC services through a more diverse array of service providers, thereby reducing dependency on traditional banks and major payment providers.Andrew Abir, Deputy Governor of the Bank of Israel, emphasized the importance of fostering a dynamic and open ecosystem with a wide variety of service providers. He stated:“Competition and innovation require a flourishing and open ecosystem with many different types of service providers. This was our initial goal in Project Sela as a proof-of-concept, and the project proved the feasibility of the model we had in mind.”Involving retail banksIn a previous model explored through Hong Kong’s Project Aurum, retail banks were entrusted with customer-facing tasks while maintaining the central bank’s operation of the wholesale ledger for the eHKD. In contrast, Project Sela introduces a novel approach where the central bank operates the retail ledger — a model akin to Israel’s digital shekel.The primary actors in Project Sela, known as Access Enablers (AEs), notably do not have control over CBDC balances, distinguishing them from conventional payment providers. Moreover, AEs are not required to maintain liquidity to support CBDC services. Their role encompasses facilitating user onboarding and CBDC access, fulfilling know-your-customer (KYC) and compliance obligations, and routing payments. The role of banks and other “funding institutions” primarily revolves around enabling the conversion of cash and deposits into CBDC.The rationale behind this approach is rooted in the emergence of technological advancements in open banking and DeFi, which have demonstrated the potential to disentangle financial services by granting users greater access to their financial data and control over their own funds.Enabling participation among the unbankedProject Sela envisions the unbanked population utilizing ATMs to convert cash into CBDC. A similar approach has recently been taken by the Chinese authorities. In the resort city of Sanya, authorities have introduced e-CNY ATMs in order to enable e-CNY access for foreign tourists.However, it is noteworthy that in many countries, the primary function of ATMs is to dispense cash rather than accept it. Consequently, the inclusion of AEs could pose challenges to traditional banking institutions, as CBDC adoption could potentially impact bank deposits.Privacy and cybersecurity considerations are implicated within Project Sela. As the central bank operates the retail ledger, ensuring the confidentiality of personal information becomes imperative. To safeguard privacy, AEs employ a hashing mechanism to obfuscate personal identifiers, although the report does not delve into the subject in detail.While Bank of Israel Governor Amir Yaron admitted that a CBDC can never be anonymous, he claimed that “if we choose to issue a digital cash shekel, it will provide at least as much privacy as other digital means of payment.”

Hong Kong’s HashKey Adds AVAX Trading

Hong Kong’s HashKey Adds AVAX TradingHashKey Hong Kong, the Chinese autonomous territory’s first licensed retail crypto exchange, has unveiled an addition to its platform with the launch of Avalanche (AVAX) trading.According to an announcement published to its website on Wednesday, HashKey has listed Avalanche on Thursday with the caveat that access to AVAX trading will be reserved for professional investors, as defined by Hong Kong’s Securities & Futures Commission (SFC).Photo by Wance Paleri on UnsplashAccessible to professional investorsTo meet the criteria as a professional investor in Hong Kong, individuals must possess an investment portfolio valued at a minimum of 8 million Hong Kong dollars, roughly equivalent to $1 million. This decision sets AVAX apart from other widely traded cryptocurrencies, such as Bitcoin and Ether, which remain accessible to retail investors in Hong Kong. While Tether (USDT) enjoys retail status, the majority of altcoins on HashKey will remain the preserve of professional investors.This move is a direct result of the SFC’s proactive stance on regulating the rapidly expanding crypto market in Hong Kong. Since the introduction of regulated retail crypto trading in the Chinese autonomous territory in August, the SFC has imposed rigorous requirements on exchanges. HashKey mandates users to deposit a minimum of 10,000 Hong Kong dollars or $1,500 into their exchange accounts as part of the Know Your Customer (KYC) verification process.Low trading volumeAmid these regulatory challenges, HashKey Hong Kong currently reports a 24-hour trading volume of approximately $5.3 million, significantly lower than its global peers. This lower trading volume suggests that stringent regulations may be affecting the exchange’s ability to attract retail investors effectively.The path to regulatory compliance in Hong Kong has been anything but smooth for crypto exchanges. Reports indicate that these platforms have collectively invested over $25 million in establishing the requisite infrastructure for obtaining a Hong Kong Virtual Asset Service Provider (VASP) license. It was reported earlier this year that crypto firms are forking out between $2.55 million and $25.5 million in order to secure a VASP trading license.Despite the challenges, HashKey is looking at various avenues in bringing its offering forward. Earlier this month the firm signed a memorandum of understanding (MOU) with insurer OneDegree. That collaboration could be significant as it should lead to the assets of HashKey users being protected and insured on the platform. That would solve a major issue for participants in the crypto space amid the backdrop of ongoing platform failures and hacks.JPEX collapseEven as regulatory efforts intensify, the crypto industry in Hong Kong has not been impervious to bad actors. The recent collapse of the JPEX crypto exchange earlier this month serves as a stark reminder of the ongoing risks associated with the industry. Described as the largest financial fraud in Hong Kong’s history, JPEX faced allegations of embezzling over $178 million of investors’ funds. Notably, JPEX was operating without SFC registration at the time of the alleged embezzlement.In response to such incidents, the SFC has taken proactive measures by publishing a warning list of crypto exchanges considered non-compliant within the Chinese autonomous territory.

Korea’s crypto exchanges resume charging fees, shifting market shares

Korea’s prominent crypto exchanges Bithumb and Korbit have recently resumed charging trading fees, local media outlet Edaily reported. However, these changes in fee policies are reinforcing Upbit’s dominant market position while downsizing Bithumb’s and Korbit’s market shares. Meanwhile, the local banks affiliated with crypto exchanges are benefitting from an uptick in fee revenue from the recent bitcoin boom. According to crypto data intelligence platform CoinGecko on Feb. 28, Upbit accounted for 77.4% of the local market share in crypto transactions, followed by Bithumb (20.43%), Coinone (1.73%), Korbit (0.35%) and Gopax (0.09%). Photo by Markus Winkler on UnsplashShifts in market sharesAs of March 2, the market shares of Bithumb and Korbit decreased by 8.59 percentage points and 0.21 percentage points, respectively. Conversely, Upbit’s dominance grew to 86.57%, up by over 9 percentage points. A Korbit official said it’s too early to pass judgment on Korbit’s market performance, as the exchange’s policies on trading fees could change depending on the market sentiment. The person added that CoinGecko tracks only eight types of tokens traded on Korbit and does not cover all the transactions on the exchange.  Bithumb had previously benefited from charging no fees, driving up its market share to as high as over 40% in December. Following the decision to impose a fee of 0.04% on Feb. 6, however, the exchange has been experiencing a drop in transaction volume. Korbit also reinstated trading fees last Thursday, roughly four months after eliminating them on Oct. 10 as a promotional move. However, it's worth mentioning that the newly introduced trading fee is 0.07%, which is lower than the earlier rate of 0.2%. Meanwhile, Gopax currently exempts fees for users who trade BTC, ETH, XRP and USDC.  No local regulations on fees for crypto transactions At the moment, there are no local regulations on fees for crypto transactions, leaving the task of setting such fees to individual trading platforms. It is known that crypto exchanges in other countries, such as the U.S., set their own rates as well.
