Gumi joins XPLA mainnet as newest validator

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.

Market speculates on Qatari investment driving bitcoin price surgeRumors are circulating within the cryptocurrency space that Qatar’s sovereign wealth fund may have dabbled in investing in bitcoin, leading to the recent surge in the bitcoin unit price.Such a move, while still an unconfirmed speculation, would be indicative of the increasing recognition of Bitcoin as a mainstream asset class. At the time of writing, bitcoin stands at $44,000. That represents a 16% increase over the space of the past week and a 166% increase since the beginning of the year.Photo by Yiğit Ali Atasoy on UnsplashKeiser’s claimAccording to outspoken Bitcoin advocate Max Keiser, Qatar’s sovereign wealth fund (QSWF), responsible for managing the nation’s significant oil and gas-generated wealth, is considering allocating up to $500 billion to the leading cryptocurrency.To provide context, this investment would eclipse the publicly disclosed bitcoin holdings of MicroStrategy, founded by Michael Saylor, by an astonishing 671 times. MicroStrategy currently holds the position of the largest corporate holder of Bitcoin, with 174,530 BTC acquired in November.Keiser speculates that the QSWF’s monumental investment could propel bitcoin’s price to new highs, reaching $100,000. Keiser tweeted:“The God Candle, a $100,000 uptick in #Bitcoin is in play. It will shift the global axis of wealth and power in 1 tick.”Custodia Bank Founder and CEO Caitlin Long shared a similar view on the X social media platform on Wednesday, pointing out that in September the Emir of Qatar had visited El Salvador and met with President Nayib Bukele. The inference is that it would have been an interest in bitcoin that may have provided the motivation for that visit, given that Bukele and El Salvador have adopted bitcoin as a sovereign currency.However, not everyone is on board with this theory. Some have pointed out that the assertion that the QSWF will invest $500 billion into bitcoin is impossible, given that the fund has $475 billion under management.Bitcoin advocate Luke Broyles weighed in on the rumor, emphasizing the crucial interplay between bitcoin’s supply and demand. Broyles highlighted the $76 billion worth of BTC still available on crypto exchanges, underscoring the fundamental principle of bitcoin’s fixed supply. According to Broyles, any substantial investment would inevitably drive prices higher.However, Broyles remains skeptical of the Qatar news, deeming it a rumor, and expressed shock if it proves remotely true. That view has led many back to the original speculation in relation to this most recent price action, the illusive bitcoin spot exchange-traded fund (ETF) approval in the United States.Some activity in recent days has suggested that BlackRock, the world’s largest fund manager, has been doing preparatory work for the launch of its iShares Bitcoin Trust ETF. Not everyone was positive on the topic of Bitcoin on Wednesday, however. Jamie Dimon, the CEO of JPMorgan Chase, testified before the U.S. Congress on Wednesday, stating “If I were the government I’d close [Bitcoin] down.”

Malaysia Looking to Wean Itself Off Dollar DependencyAccording to Prime Minister Anwar Ibrahim, China is willing to engage in discussions with Malaysia regarding the creation of an Asian Monetary Fund. This proposal, which has been circulating for decades, aims to decrease the dependence on the US dollar.©Pexels/Sergei StarostinAsian Monetary FundAnwar highlighted the necessity to minimize reliance on the dollar and the International Monetary Fund and proposed the establishment of this fund at the Boao forum in Hainan last week. He stressed that the fund would aid in diversifying the financial landscape of Asia and improving its resilience against economic challenges.Following a state visit to China last week, Anwar stated that “there is no reason for Malaysia to continue depending on the dollar.” The Prime Minister told the Malaysian parliament on Tuesday that China’s President Xi Jingping was receptive to the idea of an Asian Monetary Fund and welcomed further discussions on such a proposal.Anwar Ibrahim, serving as both the Finance Minister and Prime Minister of Malaysia, stated that the country’s central bank is already taking measures to allow for negotiations between Malaysia and China using their respective currencies, the ringgit and renminbi.The robustness of the US dollar poses a significant challenge for Malaysia and other Asian countries, particularly as Malaysia is a net importer of food. In September 2022, the Bloomberg dollar index reached an all-time high, leading to a decline in the value of the ringgit and other Southeast Asian currencies to levels not seen in decades.As a result, Anwar Ibrahim’s proposal for a shift towards bilateral trade negotiations with China using the ringgit and renminbi holds the potential to alleviate some of the region’s dependence on the dollar and reduce the impact of its fluctuations.International shift away from dollarThis development comes as other officials in the region, particularly Singapore, have been discussing strategies to manage the effects of a dominant US dollar that has weakened local currencies and been used as an instrument of economic power by the United States.There has been a raft of deals struck in recent weeks all pointing towards an international shift away from the US dollar as the global reserve currency. Russia has agreed with China to trade in renminbi. A major trade deal was struck recently between China and Brazil that will see the two countries trade in reals and renminbi. Major oil producer Saudi Arabia has made similar soundings and signed similar deals with Beijing.Bitcoin as a reserve currencyAll of this recent upheaval has brought further consideration of bitcoin acting as a reserve currency back into view. It’s expected that even if there is a shift away from the US dollar, the renminbi won’t be capable of acting as a single dominant global reserve currency. Taking to Twitter on Wednesday, Bloomberg Intelligence Crypto Market Analyst Jamie Coutts suggested that bitcoin’s performance in Q1, 2023 marks “a significant milestone in its ascendancy as a potential global reserve asset.”Coutts believes that it marks the first occasion that the leading cryptocurrency has acted as a safe haven asset during a liquidity crisis. Bitcoin remains at an early stage of development. Nobody expects that it could serve as the global reserve currency at this point. However, it is not unreasonable to anticipate it increasingly growing into a role as a reserve currency used for international trade and settlement. Especially so, as issues bubble over relative to banking and a desire to escape the clutches of US dollar domination.
