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.

Night Crows, a massive multiplayer online role-playing game (MMORPG) set in 13th-century Europe with play-to-earn (P2E) features, is set to launch next month. This global release will be available in nine languages across 170 countries, except for South Korea and China, according to a recent press release by its South Korean operator, the blockchain game company Wemade.European history with fictionDeveloped by MADNGINE, Night Crows harnesses the power of Unreal Engine 5 to deliver highly realistic battles. The game merges elements of European history with fiction, creating a unique universe for players to explore. Within this universe, players can select from four classes and eight subclasses for their characters. Thanks to its inter-server technology, Night Crows enables over 1,000 players from three servers to combat against each other in the "Battlefront," as well as collaborate and trade at the "World Exchange."Photo by Nik Shuliahin 💛💙 on UnsplashBlockchain-based economyThe March 12 worldwide launch of Night Crows incorporates the Multi Utility Token Economy (MUTE) within Wemade’s WEMIX 3.0 blockchain network. In this economy, users can complete requests to earn DIA, an in-game resource that can be used to mint Crow. The Crow token will serve as the base token for the game and will be supported on WEMIX Play’s GameFi platform. Last month, Night Crows kicked off its pre-registration campaign to attract gamers from around the globe. The game will be available for pre-download on March 11 via Google Play, the Apple App Store and the web.P2E games banned in KoreaNight Crows first made its debut in South Korea last April, where it quickly captured the interest of Korean gamers. However, the version released in Korea differs from the one planned for the global launch, as it lacks a blockchain-based economy. This absence is in line with the Game Industry Promotion Act in Korea, which prohibits the conversion of in-game resources, whether tangible or intangible, into money.

Binance Headlines List of Japan FSA Warning Letter RecipientsJapan’s Financial Services Agency (FSA) issued a warning letter on Friday stating that several foreign cryptocurrency exchanges have been operating in the country without proper registration, thereby infringing Japan’s fund settlement laws. The regulatory authority specifically named Binance, Bybit, MEXC Global, and Bitget as the entities in question.The FSA indicated that these exchanges need to register with the agency to continue operating in Japan. Failure to comply with the registration requirements would result in enforcement actions by the FSA, which could include the suspension of their operations in the country.©Pexels/David DibertUnregistered digital asset exchangesThe FSA’s warning letter detailed that the cryptocurrency exchanges mentioned had contravened Japan’s fund settlement regulations by engaging in crypto asset exchange operations without proper registration. The regulatory body emphasized that the current list of unregistered traders may not accurately reflect the current state of unregistered businesses in the country.The FSA intends to continue monitoring the market and taking appropriate regulatory measures to protect consumers and the integrity of the financial system. The agency also encouraged all unregistered operators to register with the FSA to avoid any possible enforcement actions.Clamping down on unregistered exchangesThe FSA’s recent action against unregistered cryptocurrency exchanges is in line with the regulatory body’s ongoing efforts to clamp down on non-compliant operators in Japan. In 2020, the FSA introduced new regulations mandating that all crypto exchanges must register with the agency and obtain a license to operate in the country. These regulations were put in place to strengthen consumer protection and enhance the transparency of the cryptocurrency market. By taking these measures, the FSA aims to foster a more stable and secure environment for the burgeoning crypto industry in Japan.The FSA’s warning to Binance is indicative of the growing regulatory scrutiny that the cryptocurrency industry in Japan and other nations is currently facing. Regulators are increasingly concerned about the potential risks associated with unregulated cryptocurrency exchanges, such as fraud, money laundering, and market manipulation. As a result, many regulatory bodies are implementing stricter rules and guidelines to promote transparency, accountability, and consumer protection in the cryptocurrency market.These regulations aim to create a more secure and reliable environment for investors and industry participants. The FSA’s actions against Binance serve as a reminder to all market players that compliance with regulatory requirements is critical for the long-term success of the cryptocurrency industry.Global regulatory variationWhile Japan is taking steps to implement new regulations for the cryptocurrency and Web3 sectors, the country has not been as stringent in its approach as some other major economies, such as the United States. However, this does not mean that regulators in Japan are not actively monitoring the industry and taking appropriate action where necessary.One example of such action is the recent lawsuit filed by the US Commodity Futures Trading Commission against the popular crypto exchange firm, Binance, and its founder, Changpeng Zhao, over regulatory violations. This highlights the fact that regulatory bodies in different parts of the world are taking a more proactive approach to monitoring the cryptocurrency industry.Moreover, the FSA in Japan issued a formal warning letter to Binance in 2021 for operating without the necessary permissions. This is an indication that the regulatory landscape in Japan is evolving, and that crypto exchanges must comply with the relevant regulations to avoid potential legal repercussions. While the severity of regulatory measures may differ across different jurisdictions, the message is clear: compliance is crucial for the long-term viability of the cryptocurrency industry.
