Axie Infinity co-founder suffers $9.5M loss in wallet hack

Web3 & Enterprise·February 24, 2024, 7:54 AM

Jeff “Jihoz” Zirlin, one of the co-founders of Sky Mavis, the Singapore-headquartered development firm behind both Axie Infinity and the Ronin Network, has faced a significant setback as some of his personal crypto wallets have fallen victim to a hack.

Funds drained through Tornado Cash

The hack has resulted in the loss of approximately $9.7 million worth of ether (ETH). The breach, which occurred on Feb. 23, saw two crypto wallet addresses associated with Zirlin compromised. The perpetrator managed to abscond with 3,248 ETH, funneling the stolen funds through Tornado Cash, a privacy-focused Ethereum mixer.

 

The alarm was raised by PeckShield, a blockchain investigation firm, which identified the compromise of a "whale wallet" through the Ronin Bridge. PeckShield attributed the breach to a "wallet compromise," which facilitated unauthorized outbound transfers of funds.

 

PeckShield's investigation revealed that the pilfered 3,248 ETH was initially dispersed across three different wallets before being funneled into Tornado Cash. This service, notorious for its use by hackers seeking to obfuscate the origin and traceability of illicit funds, served as a conduit for the stolen assets.

 

Confirming the attack and remarking on having had a “tough morning,” Zirkin outlined on social media that “the attack is limited to my personal accounts, and has nothing to do with validation or operations of the Ronin chain.”

 

He emphasized the implementation of stringent security protocols across all chain-related activities, seeking to reassure stakeholders of the company’s commitment to safeguarding user assets. Although specific details regarding the breach remain undisclosed, Zirlin's statement suggests a leakage of the private keys associated with his personal wallets, granting unauthorized access to the hacker.

 

Ronin Network secure

PeckShield’s revelation prompted Aleksander Larsen, co-founder of Ronin Network, to swiftly respond, affirming the robust security measures of the Ronin Bridge. The social media post that Larsen had responded to, which he claimed to have an “extremely misleading title,” was later deleted.

 

Larsen suspected that the breach stemmed from a wallet hack rather than a flaw within the bridge itself. Notably, Ronin had been targeted in a high-profile attack in March 2022, orchestrated by the North Korea-backed Lazarus Group, resulting in a $625 million loss.

In response to this previous breach Sky Mavis initiated a comprehensive overhaul of Ronin's core systems to bolster decentralization and mitigate future vulnerabilities.

 

$112M Ripple co-founder hack

In a separate incident, Binance intercepted $4.2 million worth of stolen XRP, part of the $112 million hack targeting Ripple co-founder Chris Larsen's personal wallet on Jan. 31. Unlike the Axie Infinity breach, the perpetrator behind Larsen's hack refrained from leveraging crypto mixer services or decentralized exchanges, enabling Binance to track and immobilize a portion of the illicitly obtained funds.

 

Axie Infinity, heralded as a pioneering "play-to-earn" Web3 game, has emerged as a lucrative platform, enabling players to earn cryptocurrency and trade in-game assets via blockchain technology. Since its inception in 2018, the game has amassed $1.3 billion in revenue, underscoring its prominence within the burgeoning blockchain gaming ecosystem.

Circle President visits Seoul for stablecoin talks with exchanges and central bank

Circle President Heath Tarbert, who oversees the issuer of the USDC stablecoin, arrived in Seoul on Aug. 21 for a series of meetings with South Korean cryptocurrency and blockchain industry leaders, as well as the governor of the country’s central bank. Citing industry sources, local outlet Newsis reported Tarbert visited three major exchanges, Upbit, Bithumb and Coinone, shortly after landing, spending roughly an hour at each. Discussions centered on recent developments in Korea’s digital asset ecosystem.Photo by Daniel Bernard on UnsplashGathering insight from exchangesThe trip underscores Circle’s growing interest in South Korea, one of the world’s largest crypto markets by trading volume despite its heavy tilt toward retail investors. Circle is reportedly seeking on-the-ground insight from local trading platforms. An executive from a research firm said the market offers an attractive foothold for global players looking to deepen networks. Previous reports indicated Circle has also begun informally recruiting in South Korea to support initiatives tailored to the local market, and the company is also weighing a direct investment in a domestic crypto firm. Homing in on stablecoinsStablecoins are expected to dominate the agenda with exchanges. USDC is the world’s second-largest stablecoin by market share, behind Tether’s USDT, and all three exchanges already support USDC trading. Upbit and Bithumb have meanwhile indicated their plans to develop Korean won–pegged tokens, recently filing trademark applications for their projects. Given Circle’s position in the sector, one exchange official said local platforms may look to the U.S.-based company as a benchmark, adding that practical knowledge-sharing could be the most meaningful outcome of Tarbert’s visit. Tarbert also attended a dinner with Simon Seojoon Kim, CEO of crypto venture firm Hashed, whose teams span Seoul, Singapore, Bengaluru, Silicon Valley and Abu Dhabi. Circle and Hashed have been in frequent contact, and the gathering offered another forum to exchange views on recent market developments. Talks with the central bank governorOn the policy front, Tarbert met with Bank of Korea (BOK) Governor Rhee Chang-yong at Circle’s request before the dinner. Rhee has signaled openness to the introduction of won-backed stablecoins, while emphasizing prudential safeguards and noting differences with some lawmakers on potential issuers. The BOK head has previously warned that allowing non-bank entities to issue won-backed stablecoins could pose risks, such as circumventing capital rules. The South Korean central bank is working with other agencies to develop a framework that ensures the stability and utility of stablecoins while preventing their use to bypass foreign exchange controls. The meeting between Tarbert and Governor Rhee likely covered regulatory parameters for cross-border remittances using stablecoins and avenues for public-private collaboration to foster a compliant won-stablecoin market. On the following day, Tarbert is slated to meet executives from four major financial groups: Shinhan Financial Group, Hana Financial Group, KB Financial Group and Woori Bank. Kakao Group, the company behind the KakaoTalk messaging app, is also on the itinerary. Representatives from its mobile payment platform, KakaoPay, are expected to take part in the discussions. The talks come as Kakao recently formed a task force to navigate Korea’s evolving stablecoin rules. Separately, Circle listed on the New York Stock Exchange (NYSE) earlier this year under the ticker “CRCL.” The initial public offering (IPO) priced at $31 a share and opened at $69, raising nearly $1.1 billion. As of Aug. 21, the stock closed at $131.80.

Hong Kong considers rules for fiat-backed stablecoin issuers

The Financial Services and the Treasury Bureau (FSTB) and the Hong Kong Monetary Authority (HKMA) are charting new regulatory territory with the release of a comprehensive consultation paper outlining their proposal to accept and regulate fiat-referenced stablecoins (FRS) within the Chinese autonomous territory.Photo by Ben Cheung on PexelsConsultation processThe proposal has been published to the FSTB website in the form of a consultation paper titled “Legislative Proposal to Implement the Regulatory Regime for Stablecoin Issuers in Hong Kong.” Separately, the HKMA has published a press release on the topic. This development seeks to establish a regulatory framework for stablecoin issuers and address associated risks. The consultation period is scheduled to conclude on Feb. 29 of next year. At the heart of this legislative proposal is the requirement for companies actively marketing the issuance of FRS to the public of Hong Kong to obtain a specific local license from the HKMA. The proposed criteria for obtaining this license are robust and include key elements such as maintaining reserves “at least equal to the par value” of all circulating stablecoins. This measure ensures that stablecoins remain fully backed, contributing to their stability and reliability. The legislation also places a strong emphasis on the segregation and secure safekeeping of reserve assets, enhancing the protection of users’ funds and preventing misuse. Furthermore, issuers will be mandated to provide transparent disclosure and regular reporting, fostering accountability and transparency within the stablecoin ecosystem. It is noteworthy that the proposed regulations explicitly exclude algorithmic stablecoins from obtaining an HKMA license, underlining a preference for stablecoins with solid reserve backing. No doubt the spectacular collapse of the UST algorithmic stablecoin in 2022 has informed the Hong Kong regulator’s decision to exclude consideration of algorithmic stablecoins in this instance. Need to establish Hong Kong presenceTo underscore their commitment to regulatory compliance, stablecoin issuers seeking an HKMA license will also be required to establish a registered office in Hong Kong. This office must have a chief executive, senior management team and key personnel in place, aligning with Hong Kong’s efforts to ensure that all activities related to stablecoin issuance are conducted responsibly. The proposed licensing regime for FRS aligns with Hong Kong’s broader strategy to foster the growth of the Web3 ecosystem within the region. Christopher Hui, Secretary for Financial Services and the Treasury, highlighted the significance of this move, stating: “With the implementation of the licensing regime for VA trading platforms from June this year, the legislative proposal to regulate FRS is another important measure facilitating Web3 ecosystem development in Hong Kong.” Market competitionBack in February, the HKMA signaled its intent to regulate stablecoins when it issued a discussion paper considering various regulatory approaches. Competition is on an upward trajectory relative to stablecoin issuance and use. In June, Hong Kong-based qualified custodian First Digital Trust announced that it was gearing up to launch "First Digital USD," a U.S. dollar-backed stablecoin regulated in Asia rather than the United States. Leading stablecoin issuer Circle has been active in furthering its product offering in Asia during 2023. It successfully attained licensing approval in Singapore while in Japan, it joined forces with SBI Holdings in an effort to propel further growth of its USDC stablecoin within the Japanese market.

Korea's Busan city utilizes blockchain to advance shipping and coffee industries

The Busan Port Authority (BPA) recently announced its plan to deploy a blockchain-based transshipment monitoring system known as Port-i at the port of Busan, located in the southern part of South Korea, according to local news outlet Financial News. The Port-i system is designed to streamline the management of transshipment cargo for shipping companies at Busan Port, which handles about 12.4 million twenty-foot equivalent units (TEUs) annually. The system is set for a pilot phase in January 2025, with plans to expand it to all shipping companies using the port by the second half of 2025.Photo by Christopher Lee on UnsplashEnhancing efficiency and profitability in shippingWith Port-i, shipping companies will be able to track ships and cargo through the Chain Portal, Busan Port’s integrated logistics platform. Port-i will provide a unified view of berth schedules across all terminals at the port, addressing the current issue where companies have to separately check ship and cargo statuses and independently identify berth schedules at different terminals. The BPA expects that the Port-i service will allow shipping companies to manage transshipment cargo more efficiently, improve ship loading rates and potentially increase profits. Blockchain for coffee quality controlIn addition to the Port-i initiative, Busan is also exploring other uses of blockchain technology for industrial development. The city recently set up the Busan Coffee R&D Lab, backed by the Ministry of Science and ICT, as reported by Metro.  This facility aims to use blockchain to create a platform that enhances the logistics of coffee sourcing and production, including a system that assigns unique identification to coffee products. It will provide reliable data required to control taste and quality. By integrating blockchain with artificial intelligence and advanced logistics techniques, Busan is positioning itself at the forefront of the coffee industry with innovative business models.
