HTX advisor and Tron Founder, Justin Sun, took to X (formerly Twitter) to officially confirm the recovery. In his statement, Sun revealed that HTX had not only received all the stolen funds as promised by the hacker but had also extended a gesture of goodwill. HTX rewarded the responsible party with a “white hat bonus” amounting to 250 ETH, equivalent to a substantial $400,000.Sun expressed his satisfaction with the hacker’s decision, stating:“We have confirmed that the hacker has fully returned all funds, as promised, and we have also paid the hacker a white hat bonus of 250 ETH. The hacker made the right choice. We would like to express our gratitude to everyone in the industry for their help.”Hacker advisory messageDuring the return of the funds, the hacker conveyed a message on-chain, shedding light on the reason behind this act of restitution. The message read:“Received your message. White hat bonus to0x1Fc8674A51D6b97C968BE384337519CE7003152B. Your system hot wallet private key leak, you should change system hot wallet address and reduce the system hot wallet rate.”HTX, in response to the hacker’s decision to return the funds and in accordance with its commitment, promptly sent the white hat bonus to the specified address. The exchange also requested the hacker to provide a detailed security vulnerability analysis report to the email address htxsafe@htx-inc.com.This request aims to prevent similar incidents in the future, with assurances that the hacker’s privacy will be safeguarded.Justin Sun had confirmed the original hack in September, at the time reassuring the community that HTX had covered all losses arising from the attack and resolved associated issues satisfactorily.While acknowledging the severity of the hack, Sun pointed out that the stolen amount represented a relatively small fraction of the $3 billion in assets held by HTX’s users. To incentivize the return of the funds, HTX had even offered a reward of 5%, which equated to $400,000.However, Sun also emphasized that if the funds had not been returned within a seven-day window, the company would have been compelled to involve law enforcement authorities.Thankfully, it did not come to that, and the cryptocurrency exchange can now move forward with the confidence that its users’ assets are secure. This incident highlights the importance of cooperation and ethical choices within the crypto community, as well as the potential for resolution even in the face of cyberattacks.

Upbit upgrades matching engine to process KRW 1 quadrillion trading volumeSouth Korea’s largest cryptocurrency exchange Upbit has enhanced its matching engine — which matches buy and sell orders from users on the exchange — to be able to handle a daily trading volume of KRW 1 quadrillion (approximately $757.3 billion), according to local news outlet Kyunghyang Games.Photo by Maxim Hopman on UnsplashBecause the crypto market operates nonstop without limits to time or borders, having a solid infrastructure that can seamlessly handle large amounts of data is crucial. Upbit has thus been working on its so-called “Stairway to Heaven” project for the past two years to upgrade its trading infrastructure, including its matching engine.Constant upgradesThe Stairway to Heaven is a long-term project in which Upbit’s operator Dunamu has invested a total of KRW 10 billion (approximately $7.6 million) to adjust to the rapidly advancing crypto industry and improve the performance of the entire market system. The upgradesThe main goal of the project is to upgrade Upbit’s matching engine to be cloud-native and horizontally scalable. The engine is now capable of supporting more than 40,000 transactions per second — a 25-fold increase from the previous version of the engine — allowing it to respond efficiently to surges in user traffic. In the event of a traffic spike, the system can handle more than 100,000 transactions per second with additional servers, the exchange said.“Unlike the way traditional finance approaches ledger management, our cloud-native architecture allows us to flexibly respond to surges in traffic,” Upbit said. “We will continue to make various system improvements to offer a stable investment environment.”Elevating the user experienceIn addition to upgrading its matching engine, Upbit has recently revamped its UI/UX to include price chart updates by second increments and an overview of profits and losses. The exchange plans to continue its multifaceted efforts in service quality, security and investor protection to become a domestically and globally recognized exchange.
