Jeung-rock Choi (also romanized as Choi Jeongrok) is a name associated with at least two prominent South Korean executives in the financial technology and blockchain sectors. One is an executive within the Hecto Group, holding leadership roles at Hecto Financial and Hecto WalletOne. The other is a director at Shinhan Bank, leading its blockchain business division.

Jeung-rock Choi (Hecto Group Executive)

Jeung-rock Choi is a South Korean business executive in the financial technology sector, known for his leadership roles within the Hecto Group. As of early 2026, he serves concurrently as the Chief Executive Officer (CEO) of Hecto WalletOne and as the Managing Director and Head of the Planning Division at Hecto Financial. ^{[1] [2]} He is recognized for his dual expertise in traditional financial systems and the emerging digital asset landscape, with a particular focus on stablecoins and digital wallet infrastructure. ^[2]

Career

Choi began his career in the traditional financial sector before transitioning into technology and business management. He later joined Hecto Innovation, a subsidiary of the Hecto Group conglomerate. Within Hecto Innovation, he took charge of the blockchain business subsidiary, where he was responsible for building the foundational strategy and operations for the Hecto Group's expansion into the blockchain space. ^[1]

In a significant leadership shuffle in January 2026, Choi was appointed to two key positions. He was named CEO of Hecto WalletOne following Hecto Innovation's acquisition and rebranding of the company, previously known as WalletOne. Simultaneously, he was appointed as the Head of Planning for Hecto Financial, another affiliate within the group specializing in payment services. This dual appointment gave him a clear mandate to integrate Hecto WalletOne's digital asset wallet technology with Hecto Financial's established payment platforms, aiming to create synergistic value and advance the group's capabilities in the Web3 domain. ^[1]

Vision and Strategic Focus

Choi has articulated a vision that positions the digital asset wallet as a core piece of infrastructure for the next phase of the internet. He believes a wallet is more than a simple storage tool, describing it as "an essential software in the blockchain ecosystem" that facilitates asset transfers, transaction signing, asset management, and access to decentralized Web3 services. He views the wallet as a "critical gateway to the upcoming Web3 era." ^[1]

His primary strategic goal is to evolve Hecto WalletOne from a simple wallet provider into a comprehensive blockchain infrastructure company. This vision is built upon three core pillars:

• Wallets: Providing the core technology for users to manage digital assets and interact with blockchain networks.
• Payments: Leveraging his concurrent role at Hecto Financial to integrate seamless payment functionalities.
• Authentication: Using wallet technology as a secure method for identity and access management in the Web3 space.

A key area of his expertise is stablecoins, which he views as a foundational technology for the next generation of cross-border payments and a vital component in the future of global finance. ^[2]

Public Engagements

Choi is a scheduled speaker at the ETHCapital Summit 2026, an event taking place in Seoul, South Korea. On April 15, 2026, he is slated to participate in a panel discussion titled, "Stablecoin Play: The Future of Won-Pegged Stablecoins in Korea," where he is expected to share his insights on the role of stablecoins in the country's financial ecosystem. ^[2]

Jeung-rock Choi (Shinhan Bank Executive)

Jeung-rock Choi (also romanized as Choi Jeung-rok) is a prominent figure in South Korea's institutional finance and blockchain sector, serving as the Director of the Blockchain Business Division at Shinhan Bank. ^[3] In this role, he spearheads the bank's strategic initiatives related to blockchain technology, digital assets, token securities, and Web3 innovation. ^[3]

Career

Before joining Shinhan Bank, Choi was a team leader at The Boston Consulting Group (BCG). At BCG, he specialized in developing digital transformation strategies for major financial institutions, gaining experience that would directly inform his subsequent work in banking innovation. He was later brought into Shinhan Bank to lead its newly formed Blockchain Business Division, tasked with positioning the traditional banking giant at the forefront of financial technology. ^[3]

Key Projects and Achievements at Shinhan Bank

As the head of the Blockchain Business Division, Choi has led and overseen several pioneering projects that have marked significant milestones for both Shinhan Bank and the South Korean financial industry.

B2B Token Securities Settlement Service

In January 2026, Choi's division launched South Korea's first B2B token securities settlement service in a strategic partnership with the global digital asset company BitGo. The service enables corporate clients to use tokenized securities as collateral for loans denominated in Korean Won (KRW). A key feature is an automated liquidation process for settlement in the event of a default, designed to enhance the liquidity of the nascent token securities market. Regarding the launch, Choi stated, "With the upcoming institutionalization of token securities, we have preemptively prepared a service that can enhance the liquidity of token securities for corporate clients... We will continue to expand our digital asset service ecosystem to include not only physical assets but also various virtual assets." ^[3]

Anti-Money Laundering (AML) Blockchain Patent

Under Choi's leadership, Shinhan Bank secured a patent for an "anti-money laundering system and method on a private blockchain." This technology addresses a critical challenge in institutional blockchain adoption by enabling real-time identity verification of transaction participants and automating the monitoring of suspicious transactions on private distributed ledger technology (DLT) networks. The system aims to enhance security and regulatory compliance for digital asset transactions. Choi commented that the patent allowed the bank to "secure the technological basis to provide more reliable and secure services in the digital asset market," and affirmed the bank's intent to "continue to lead digital financial innovation." ^[3]

Stablecoin Remittance Proof-of-Concept

Choi led the world's first stablecoin remittance Proof-of-Concept (PoC) conducted on the Hedera Hashgraph public network. This project tested the technical feasibility and operational efficiency of using stablecoins for international money transfers, representing a significant research endeavor by a major bank into the practical applications of stablecoins beyond trading. ^[3]

Central Bank Digital Currency (CBDC) Project

Choi was involved in the Bank of Korea's (BOK) national Central Bank Digital Currency project. His and Shinhan Bank's participation contributed to the research and development efforts for a potential digital won, underscoring the collaborative role of private banks in the exploration of national digital currencies. ^[3]

Digital Asset Custody Service

He also played a central role in the development and establishment of Shinhan Bank's digital asset custody service. This service is a foundational component of the bank's broader digital asset platform, providing the secure storage necessary for the bank to offer more complex products and services involving digital assets to its institutional clients. ^[3]
