Report on Hong Kong’s fintech sector reveals solid blockchain growth

Korea’s prominent crypto exchanges Bithumb and Korbit have recently resumed charging trading fees, local media outlet Edaily reported. However, these changes in fee policies are reinforcing Upbit’s dominant market position while downsizing Bithumb’s and Korbit’s market shares. Meanwhile, the local banks affiliated with crypto exchanges are benefitting from an uptick in fee revenue from the recent bitcoin boom. According to crypto data intelligence platform CoinGecko on Feb. 28, Upbit accounted for 77.4% of the local market share in crypto transactions, followed by Bithumb (20.43%), Coinone (1.73%), Korbit (0.35%) and Gopax (0.09%). Photo by Markus Winkler on UnsplashShifts in market sharesAs of March 2, the market shares of Bithumb and Korbit decreased by 8.59 percentage points and 0.21 percentage points, respectively. Conversely, Upbit’s dominance grew to 86.57%, up by over 9 percentage points. A Korbit official said it’s too early to pass judgment on Korbit’s market performance, as the exchange’s policies on trading fees could change depending on the market sentiment. The person added that CoinGecko tracks only eight types of tokens traded on Korbit and does not cover all the transactions on the exchange.  Bithumb had previously benefited from charging no fees, driving up its market share to as high as over 40% in December. Following the decision to impose a fee of 0.04% on Feb. 6, however, the exchange has been experiencing a drop in transaction volume. Korbit also reinstated trading fees last Thursday, roughly four months after eliminating them on Oct. 10 as a promotional move. However, it's worth mentioning that the newly introduced trading fee is 0.07%, which is lower than the earlier rate of 0.2%. Meanwhile, Gopax currently exempts fees for users who trade BTC, ETH, XRP and USDC.  No local regulations on fees for crypto transactions At the moment, there are no local regulations on fees for crypto transactions, leaving the task of setting such fees to individual trading platforms. It is known that crypto exchanges in other countries, such as the U.S., set their own rates as well.  

Socket, a cross-chain infrastructure protocol, and its interoperability bridging platform, Bungee, have restarted operations following a temporary pause prompted by an exploit that led to the apparent theft of $3.3 million.Photo by Anna Tarazevich on PexelsSecurity incidentTaking to the company’s Discord, Socket team hospitality lead Taylor Melvin clarified that it had “experienced a security incident which affected wallets with infinite approvals to Socket contracts.” The incident, which occurred on Tuesday, involved an unknown attacker draining millions worth of stablecoins and other tokens from the Bungee bridging aggregator. The attackers targeted wallets with infinite approvals to Socket contracts, exploiting authorizations for blockchain-based tools that allow applications to access tokens in a user's wallet. Security researcher "@speekaway" was the first to flag the exploit on Tuesday. The attacker's wallet, connected to the exploit, held nearly $3 million in ether (ETH) and $300,000 worth of other tokens. By 2:47 p.m. ET, the attack seemed to have ceased, with the researcher recommending users to revoke approvals for Socket to safeguard their assets. Pausing contractsIn response to the security breach, Socket announced the pause of affected contracts on Tuesday at 3:15 p.m. ET. The project's team promptly identified and addressed the issue, taking swift action to mitigate the exploit's impact. @speekaway chimed back in once contracts had been paused, writing:”Think this pause fixed it, very likely no more attacks are possible. So if you are currently freaking out about revoking you can probably relax.” Normal service returnsAs Socket paused activity during the incident, preventing further propagation of the attack, developers worked to fix the issue. Early Wednesday, Socket developers announced that the problem had been resolved, and normal activities had resumed. The team also stated that plans for compensation were in progress. Cross-chain bridges, like Socket's Bungee, facilitate token transfers between different blockchains but remain susceptible to exploitation. Blockchain security and data analytics company PeckShield confirmed that at least $3.3 million had been lost, highlighting the need for enhanced security measures in the rapidly evolving blockchain ecosystem. The exploit involved the exploitation of a recently added route, which has since been disabled. The attacker targeted users who had over-approved Socket, draining funds up to the limit of their approval. This incident follows the $81 million hack of Orbit Chain, a cross-chain bridge connecting Ethereum to other networks, earlier in January. Cross-chain tools' complexity contributes to the frequency of such attacks, emphasizing the importance of understanding the security measures in place when utilizing these bridges. In a message to CoinDesk, Sergey Nazarov, co-founder of Chainlink, emphasized the need for users to scrutinize the security of their chosen bridge, considering the various levels of cross-chain security. With the complexities involved, users are encouraged to be vigilant and informed about the security spectrum of the bridges they employ. Socket was founded by Indian duo Rishabh Khurana and Vaibhav Chellani. In September, the company raised $5 million, with funding coming from Framework Ventures and Coinbase Ventures. 

Upbit D Conference participants share insights on Web3 and blockchainBlockchain specialists from 29 countries gathered on Monday (local time) at Upbit D Conference (UDC) 2023 in Seoul to explore capital markets in the forthcoming Web3 era. This era is characterized by user-controlled, communal data management, a notable shift from the Web2 space where major tech corporations held dominant control over data.Organized by Dunamu, the operator of South Korea’s Upbit cryptocurrency exchange, the conference featured 39 experts, focusing on the transformative potential of blockchain technology in this new internet phase.Photo by Shubham Dhage on UnsplashAsset tokenization and investment opportunitiesAccording to a report by the Asia Business Daily, one of the key speakers at the conference, Wally Yu, a Solutions Architect at San Francisco-based Chainlink Labs, delved into how cross-chain solutions and asset tokenization could add to the financial industry. He explained that Chainlink’s Cross-Chain Interoperability Protocol (CCIP), designed to connect various blockchains, is only beginning to reveal its capabilities in integrating with traditional financial markets. Yu pointed out the growing interest from banks in tokenizing their conventional assets and transferring them to the blockchain. This move, he suggested, could lead to increased liquidity and open up new investment opportunities.Yu also compared the current DeFi market to traditional sectors like stock, real estate, and derivatives, noting DeFi’s relatively smaller scale. However, he underlined blockchain’s transparency as a key advantage over traditional markets, where transparency is often lacking. According to Yu, the adoption of blockchain by traditional financial firms could address longstanding issues more effectively.Looking ahead to the Web3 era, Yu envisioned a scenario where different tokens are interconnected, potentially bringing an estimated $900 trillion worth of assets onto the blockchain. This, he believes, would significantly enhance liquidity in the financial markets.From Web2 to Web3During the conference, Korean mobile network provider SK Telecom’s (SKT) Vice President, Oh Se-hyun, outlined the company’s forward-looking strategy to transition its 30 million subscribers from Web2 to Web3. She highlighted SKT’s search for high-value markets to expand its business scope, underscoring the company’s active efforts in constructing Web3 infrastructure. This strategic pivot aligns with their vision for the upcoming Web3 era.SKT, which established its Web3 division in 2017, initially engaged in developing a private mainnet. However, the company has since shifted its focus towards services aimed at boosting customer engagement, such as custody, web and app services. Oh emphasized the need for Web3 wallets to support a diverse range of assets and decentralized applications (dApps), but she stressed that ease of use is paramount. She views that these wallets will serve as gateways for customers entering the blockchain space.SKT has developed and is improving its own Web3 wallet, dubbed Wallet T. Oh shared her belief that the future of financial business models will pivot from traditional and big-tech banks to those based on public chains. In preparation for this shift, SKT is contemplating strategies to embrace blockchain-based Web3 services.Crypto regulationThe conference also touched on the potential integration of virtual assets within regulatory frameworks. There’s growing anticipation in the market for the approval of spot bitcoin exchange-traded funds (ETFs) by the United States Securities and Exchange Commission, especially following the inclusion of asset manager BlackRock’s proposed spot bitcoin ETF in the Depository Trust and Clearing Corporation’s (DTCC) clearing-house eligibility file.Emily Parker, Executive Director at CoinDesk, mentioned that a spot bitcoin ETF is on the horizon in the U.S. She anticipated that such a development would not only boost cryptocurrency prices but also positively impact the market for non-fungible tokens (NFTs). Echoing this sentiment, Oh Se-hyun from SKT predicted that the approval of a spot bitcoin ETF could unlock access to a $30 trillion market.SKT’s Oh also addressed the complexities surrounding the regulatory landscape for cryptocurrencies. She acknowledged the challenge facing authorities in developing these regulations all at once, highlighting the gradual progress in this area. She cited the outcome of Ripple’s lawsuit in the U.S., which resulted in Ripple’s XRP tokens being classified differently for different investors: as a security for institutional investors but not for retail investors. Additionally, Oh pointed to the upcoming Markets in Crypto-Assets Regulation (MiCA) in the European Union, slated for implementation in December 2024. She emphasized that the establishment of such regulatory guidelines brings clarity and reduces uncertainty, which can be reassuring for businesses operating in the crypto space.Providing further insights into this matter, Kim Gap-rae, a senior researcher at the Korea Capital Market Institute (KCMI), spoke about the importance of regulatory clarity in the cryptocurrency sector. He pointed out that it’s more crucial for governments to have clear regulations rather than focusing on the extent of regulation. Understanding new regulatory or legislative trends is essential for governments as they look to develop new infrastructures.According to Kim, a potential spot bitcoin ETF approval in the U.S. could prompt South Korea to consider a similar approval. However, he noted that Korea currently lacks a regulatory framework for Bitcoin custody, which could lead to a competitive environment among crypto companies in the country. Kim believes that a deeper understanding of custodian regulations will enable better adaptation to new types of ETFs and foster their growth in Korea.
