Singapore’s UniPass Plays Role in ERC-4337 Vulnerability FixSmart contract wallet provider UniPass and crypto infrastructure firm Fireblocks have successfully addressed a significant vulnerability in the Ethereum ecosystem.Photo by Nenad Novaković on UnsplashAccount abstraction vulnerabilityThis vulnerability, identified as the ERC-4337 account abstraction vulnerability, posed a critical security risk to hundreds of mainnet wallets. The joint effort between Fireblocks and UniPass was detailed in a blog post published to the Fireblocks website on Thursday.This vulnerability, if exploited, could have enabled a malicious actor to execute a complete takeover of the UniPass Wallet by manipulating Ethereum’s account abstraction process. The vulnerability represented a substantial threat to the security of smart contract wallets, as it could lead to unauthorized access and fund drainage.Improving user experienceAccount abstraction, as dealt with via ERC-4337, is a mechanism that introduces a novel way of processing transactions and interacting with smart contracts on the Ethereum blockchain. It allows for a more flexible and efficient handling of transactions, transcending the traditional distinction between externally owned accounts (EOAs) and contract accounts.EOAs are controlled by private keys and can initiate transactions, while contract accounts are governed by the code of a smart contract. When an EOA initiates a transaction with a contract account, it triggers the execution of the contract’s code. Account abstraction introduces the notion of abstracted accounts, which are not tied to a specific private key and can initiate transactions and interact with smart contracts, similar to EOAs.In the context of ERC-4337, an account executing an action relies on the EntryPoint contract to ensure that only signed transactions are executed. Typically, these accounts trust a single audited EntryPoint contract to validate user operations before executing commands. However, the vulnerability resided in the fact that a malicious or buggy EntryPoint contract could potentially skip the validation step and directly call the execution function, bypassing essential security measures.This vulnerability, identified by the two firms, had allowed attackers to seize control of UniPass wallets by replacing the trusted EntryPoint of the wallet. Once this takeover was completed, the attacker could access the wallet and drain its funds.It’s worth noting that the vulnerability posed a threat to several hundred users who had activated the ERC-4337 module in their wallets, making them susceptible to exploitation by any actor on the blockchain. Fortunately, the wallets affected by this vulnerability contained only small amounts of funds, and swift mitigation efforts were successful in preventing further harm.Company mergerEarlier this year, Singapore’s UniPass merged with Chinese wallet provider Keystone to form Account Labs, a company which has been incorporated in Singapore. At the time, Keystone founder Liu Lixin outlined that further developing account abstraction-derived products was the objective of the creation of Account Labs. He stated:“We are on the cusp of a Web3 Account Abstraction revolution. Together, we’ll drive rapid transformation, making the transition from Web2 to Web3 effortless for users. Our goal is to ensure everyone can securely and smoothly manage a decentralized account. We welcome partners to join us in advancing the Web3 account domain.”In furthering that objective, Account Labs announced on Thursday that it had raised $7.7 million in a funding round led by Amber Group, MixMarvel DAO Ventures, and Qiming Ventures.

Chinese Central Bank Official Emphasizes Need for Digital Yuan Retail PaymentsA senior official from the People’s Bank of China (PBOC) has underscored the importance of making China’s digital yuan, commonly referred to as the e-CNY, accessible in all retail payment scenarios within China.Photo by Eric Prouzet on UnsplashStreamlining retail e-CNY paymentsThe remarks were delivered by Changchun Mu, Head of the Digital Currency Research Institute, during a trade forum in Beijing. Mu emphasized the need for standardizing QR codes in payment systems, particularly those dominated by giants like WeChat Pay and Alipay.Local media reported on Sunday that the central bank official highlighted that various wallet providers, including WeChat, Alipay, commercial banks with mobile banking apps, and other payment apps associated with e-CNY operations, must remain vigilant about complying with relevant financial regulations and obtaining the necessary licenses. He stressed that the initial step in this process should involve the adoption of the digital yuan as the preferred payment method for all retail transactions.Standardizing QR code paymentsMu explained that in the short term, authorities can start by unifying QR code standards on a technical level to achieve barcode interoperability. In the long run, he suggested that they will steadily implement the upgrade of payment tools.The move towards standardizing QR code payments aligns with the central bank’s commitment from the previous year to promote universal QR payment codes. This initiative aims to allow consumers to make payments by scanning a unified barcode. Currently, QR code payment systems are widely prevalent in China, with WeChat Pay and Alipay being dominant players.The PBOC has been actively testing the e-CNY, having introduced a pilot app in January 2022. The digital yuan pilot programs, initiated in late 2019, have expanded to encompass at least 26 locations across 17 provincial-level cities and regions, including major cities like Beijing, Shanghai, Shenzhen, and Suzhou, according to state media Xinhua.The extent of China’s promotion of its digital yuan has been unmatched despite the fact that most central banks globally have had ongoing central bank digital currency-related (CBDC) projects open for a number of years already.Recent months have seen the launch of a whole host of initiatives to further the use of the CBDC. These initiatives have included integration of the currency into the education system in Jiangsu province, the installation of digital yuan ATMs in Hainan, among many other such projects, and paying state employees with the currency in Changshu. That said, despite these efforts, widespread adoption of the e-CNY remains a work in progress.Bringing about e-CNY integrationMu also emphasized that the existing interbank payment and settlement systems function effectively, indicating that there is no immediate need to replace them with the CBDC system. Instead, he suggested that seamless integration could be achieved by ensuring comprehensive interoperability between the e-CNY and existing electronic payment tools and commercial bank deposit systems.Moreover, at a wholesale level, Mu proposed the use of the digital yuan for settlement within the financial market infrastructure. Smart contracts could also be leveraged for such activities, thereby enhancing efficiency in wholesale payments.Mu’s remarks underscore the Chinese central bank’s determination in advancing the development and adoption of the digital yuan while ensuring it remains integrated into the existing financial ecosystem.

Zero Two Enters Into JV to Develop First Middle East Mining OpZero Two, a digital assets development company based in Abu Dhabi in the United Arab Emirates (UAE), has partnered with leading North American crypto miner Marathon Digital in a joint venture that will result in the development and operation of the Middle East’s first large-scale crypto mining facility.Photo by Manuel Geissinger on PexelsInitial capacity of 250 MWIn a press release issued on Tuesday, Marathon Digital outlined that the venture is focused on accelerating the global digital economy while also supporting Abu Dhabi’s power grid.To progress the project, the two companies have formed the Abu Dhabi Global Markets JV Entity (AGDM Entity). Initially, two digital asset mining facilities, with a combined capacity of 250 MW, will be developed.One site, at Masdar City, Abu Dhabi, will account for 200 MW of that capacity. The remaining 50 MW capacity will be developed at a site located in the port area of Mina Zayed. The strategy of the firms is to exploit excess network energy in Abu Dhabi. The firms see this as a win/win as increasing the base load of the Abu Dhabi power grid will result in a more sustainable grid. The companies intend to supplement any use of non-sustainably produced energy with carbon offset certificates.80/20 equity splitThe two firms have agreed upon an 80%/20% equity split, with Zero Two being the lead investor. In the initial development period for the venture during 2023, both entities will contribute resources to the joint venture in proportion to the equity division, in the form of capital, equipment and infrastructure.Zero Two and Marathon had previously collaborated on a pilot project with the objective of determining the feasibility of building a large-scale facility. Air-cooled miners have not proven to be a success in hot arid climates like that of the Rub Al Khali Middle Eastern desert.The upshot of the pilot program was a determination that a custom-built immersion-cooled system would be feasible. Mining equipment for the facilities is already on order while construction at the two sites is underway. Both sites are expected to go online before the end of the year with a combined hashrate of 7 EH/s.Ahmed Al Hameli commented on the joint venture: “This alliance leverages Zero Two’s regional expertise, expansive relationships, and growing blockchain infrastructure development and operational capabilities, with Marathon’s technical prowess in developing digital asset sites and innovative mining technologies.These synergies create a powerful combination and lay the groundwork for the success of this pioneering project in the Middle East. Marathon shares our commitment to actively supporting Abu Dhabi’s power grid and developing global digital assets infrastructure. We look forward to working with them on this venture.”Jurisdictional arbitrageMarathon’s CEO Fred Thiel said that Zero Two’s regional relationships were an optimal compliment. It may be both a timely and shrewd move by Marathon to develop this project in the Middle East region. In recent weeks the Biden administration floated the idea of a 30% crypto mining tax. Crypto mining is a global endeavor.That type of additional overhead would make it very difficult for North American miners to remain viable. By opening up new working relationships in other regions, the company may be in a better position to pivot should North America and the firm’s Montana-based mining facility become unsustainable.
