Kronos Research experiences significant cybersecurity breachKronos Research, a Taipei-based crypto trading, market making and venture capital firm, has found itself in the crosshairs of a cyber attack.Photo by FLY:D on Unsplash$25.6 million lossHackers gained unauthorized access to the company’s API keys, resulting in losses exceeding $25.6 million spread across various cryptocurrencies, prompting a concern within the crypto community.The breach was detailed by the company in a social media post on the X platform on Saturday. That post read:“In the interest of transparency Around 4 hours ago, we experienced unauthorized access of some of our API keys. We paused all trading while we conduct an investigation. Potential losses are not a significant portion of our equity and we aim to resume trading as soon as possible.”On-chain sleuthingInvestigations by crypto community members have followed, led by blockchain researcher ZachXBT. ZachXBT is a well-known anonymous persona in the crypto space, having earned a reputation for uncovering hacks, scams and unethical practices within the crypto sector.In this instance, ZachXBT uncovered a trail of transactions originating from a Kronos Research account. The meticulous execution of the cyber attack was evident in six transactions involving 2,780 ETH, 2,540 ETH (repeated twice), 2,636 ETH, 4.93 ETH and 2,507.52 ETH, all directed to addresses controlled by the hacker.Kronos Research has followed up with a tweet thread on X, acknowledging the gravity of the situation and confirming losses of approximately $25.65 million in crypto assets. Despite the alarming figures, the company sought to reassure stakeholders by emphasizing that the losses represent a relatively small fraction of its total equity. In a commendable display of accountability, Kronos Research pledged to absorb all losses internally, shielding its partners from the financial ramifications of the breach.The Taiwanese firm posted:“Our team has been working round the clock to minimize the impact and resume trading operations, following a hacking incident that involved unauthorized access to our API Keys.”Implications for Woo XThe operational repercussions were swift and impactful, with Kronos Research opting for a temporary suspension of all trading operations. This decision rippled through to Woo X, the affiliated Taipei-based exchange and liquidity provider created by Kronos, which temporarily blocked specific asset combinations due to liquidity concerns. Importantly, Woo X assured users of the security of their funds and later announced the resumption of spot and perpetual trading.Looking forward, Kronos Research outlined its intention to resume trading operations in the coming days, contingent on favorable conditions.The cyber attack on Kronos Research occurred against the backdrop of heightened cybersecurity concerns within the crypto space. According to blockchain security firm Certik, approximately $173 million was lost to crypto attacks in November alone. The Kronos Research breach follows on the heels of Poloniex’s $131 million hack, highlighting the persistent challenges faced by crypto platforms in securing user assets.

Cronos Labs launches zkEVM chain testnetCronos Labs, the developer behind the Cronos blockchain ecosystem, is charting a new path in the blockchain space by launching a zkEVM chain.From Cosmos to EthereumThe Cronos zkEVM chain is being launched in the first instance as a test network. The layer-2 blockchain will rely upon ZK Stack, the software kit developed by Matter Labs. In this way, the project will be extending its scaling roadmap from Cosmos to Ethereum. As Matter Lab’s SVP of Business and Operations, Marco Cora put it:“When we introduced the ZK Stack, we opened up the door for anyone wanting to build on top of Ethereum to do so by deploying hyperchains. Whether you’re building a specialized Rollup or a general purpose one, hyperchains allow you to tap into Ethereum’s extensive userbase base and liquidity while preserving its robust security and decentralization.”The journey began with the creation of the first chain in the Cronos ecosystem — a Cosmos appchain developed in collaboration with Singapore-headquartered crypto platform Crypto.com and launched in 2021. Subsequently, Cronos introduced an EVM-compatible chain in 2022, built using the Cosmos SDK. Notably, these new endeavors complement, rather than replace, the earlier established chains.Photo by Kanchanara on UnsplashThe product of collaborative effortsA significant development in Cronos’ evolution is the introduction of zkEVM, a result of collaborative efforts involving Cronos Labs, Matter Labs and engineering teams from stakeholders Crypto.com and existing dApp developers. The zkEVM testnet is a breakthrough, utilizing Ethereum’s Sepolia testnet and incorporating zkSync’s open-source prover, Boojum — a STARK-based zero-knowledge proof system known for its efficiency in the layer-2 rollup space, with low hardware requirements and fees.The decision to launch a native Ethereum chain stemmed from challenges in bridging EVM chains and bridging between Cosmos and Ethereum, according to Ken Timsit, Managing Director at Cronos. Timsit emphasized the richness and robustness of the Ethereum developer ecosystem for building DeFi and NFT applications.Native account abstractionHyperchains within the ZK Stack share components, including a native bridge to the Ethereum mainnet and zkSync’s trustless bridging mechanism, ensuring assets remain secured by Ethereum. The implementation of zkSync’s native account abstraction allows transaction fee payments in various cryptocurrencies, including Cronos’ native token (CRO).Cronos’ zkEVM is anticipated to progress to the mainnet in the second quarter of 2024, marking a pivotal moment in the evolution of hyperchains.The landscape of hyperchains is expanding, with projects like GRVT and Tradable utilizing the ZK Stack. GRVT, a derivatives exchange, and Tradable, a tech firm focused on bringing private credit on-chain, exemplify the diversity and specialization within this emerging sector. Tradable aims to establish an institutional-focused hyperchain, potentially forming a decentralized chain alongside other institutional partners.Matter Labs views the zkSync hyperchain as a superior option compared to app-specific chains in Cosmos, emphasizing the scalability and security benefits. Hyperchains, a potential alternative to private blockchain frameworks like Hyperledger or Corda, offer technical scalability with the benefits of Ethereum. However, practical scalability remains a challenge due to cost considerations and the social coordination problem.

SC Ventures and Deutsche Bank Execute Stablecoin Payments via UDPNSC Ventures, the Singaporean disruptive technology investment subsidiary of UK banking conglomerate Standard Chartered, has partnered with Deutsche Bank in completing the first successful proof of concept (PoC) for the Universal Digital Payments Network (UDPN).Photo by Conny Schneider on UnsplashConnecting blockchain networks with CBDCsThe UDPN is a brainchild of Hong Kong’s Red Date Technology, which in turn is a co-founder of the Chinese Blockchain-Based Service Network (BSN). The PoC was aimed at facilitating seamless connections between central bank digital currencies (CBDCs) and various blockchain networks through message-based transactions.News of the successful PoC emerged via a report by India’s English-language business newspaper Financial Express earlier this week. In conventional finance and international payments, the Society for Worldwide Interbank Financial Telecommunication (SWIFT) is the foremost, dominant financial messaging service. Notably, UDPN distinguishes itself from SWIFT as it operates on a permissioned blockchain, ensuring heightened security and regulatory compliance.As part of the PoC, several real-time transfers and swaps of synthetic USDC and EURS (Stasis Euro stablecoin) were executed between the two banks. While SC Ventures utilized code that leveraged UDPN software development kits (SDKs) and APIs, Deutsche Bank employed a graphical user interface. Rafael Otero, CTO and CPO of Deutsche Bank’s Corporate Bank division, emphasized the significance of this trial, stating that it provides an opportunity to explore how clients can actively engage in the decentralized global economy. Otero sees this as the logical next step in the evolution of financial transactions.Overcoming digital currency adoption challengesUDPN has been under development in collaboration with consultancy firm GFT Technologies and DLA Piper’s Hong Kong-based digital asset creation platform, TOKO, with further governance provided by the UDPN Alliance.The primary goal of UDPN is to overcome the hurdles that hinder the broader adoption of digital currencies, especially in the face of the surging number of CBDCs, stablecoins, and deposit tokens. The lack of interoperability among these digital assets necessitates innovative solutions.Currently, interoperability among stablecoins primarily relies on centralized cryptocurrency exchanges. However, due to the absence of proper oversight and regulatory framework in these exchanges, this method is not a sustainable solution for achieving interoperability between CBDCs and deposit tokens.UDPN takes a unique approach by providing a decentralized identity infrastructure. The actual currency transactions occur on their respective native blockchains or infrastructures. This means that UDPN enables users to seamlessly swap a USDC stablecoin on one network for a Euro stablecoin on another or even a bank deposit token.Improving upon financial messaging systemsAs UDPN incorporates an element of financial messaging for digital currencies, this hybrid approach streamlines transactions, eliminates the need for reconciliations, and enables atomic settlement. Therefore, UDPN ensures that either both sides of a transaction succeed or both fail. In contrast, purely messaging-based systems can result in one side of the transaction failing.SWIFT recently experimented with a messaging solution to connect CBDCs, and other conventional integration methods are being explored, involving APIs and routing networks, such as finP2P. It has collaborated with the central banks of Hong Kong and Kazakhstan recently in testing CBDC connectors.A report by Nikkei Asia last week suggested that Standard Chartered is venturing further into the world of digital currencies, particularly so in Asia, via SC Ventures.
