Parataxis Holdings LLC Announces Definitive Agreement with Sinsiway Co. Ltd. (KOSDAQ: 290560), to Bring Institutionally-Backed, Ethereum Treasury Company to the South Korean Public Markets

SEOUL, South Korea & NEW YORK--(BUSINESS WIRE)-- Parataxis Holdings LLC (“Parataxis Holdings”), an affiliate of Parataxis Capital Management LLC (“Parataxis Capital” or “PCM”), together with other affiliated entities, has entered into a definitive agreement with Sinsiway Co. Ltd. (KOSDAQ: 290560) (“Sinsiway” or the “Company”) in a transaction valued up to KRW 35 billion, which would result in Parataxis Holdings affiliates holding a controlling interest in the Company (the “Transaction”). Following the closing of the Transaction, the Company intends to change its corporate name to Parataxis ETH, Inc. and remain listed on the KOSDAQ. The Transaction is subject to closing conditions.

The Transaction would result in the creation of South Korea’s first Ethereum-based treasury platform listed on South Korean public markets, that is anchored by US-based institutional investors with significant experience in managing digital asset investments.

As part of the Transaction, Edward Chin, Founder and CEO of Parataxis Holdings, and Co-Founder & CEO of Parataxis Capital, will be joining the Board of Directors of the Company. Michael Myunghoon Lee, of Com2uS and CRIT Ventures, will assume the role of CEO of the Company.

“Following the recent transaction that created our franchise’s inaugural Bitcoin treasury platform, Parataxis Korea, Inc., we are excited to announce Parataxis ETH, Inc. as an independent, differentiated Ethereum treasury platform that will bridge traditional institutional finance and the on-chain digital economy of Ethereum,” said Edward Chin. “Ethereum continues to play a central role in major use cases such as stablecoins, decentralized finance, and gaming, supported by growing institutional participation. With this Transaction, the Parataxis Holdings team is proud to bring the two most dominant digital assets in Bitcoin and Ethereum to the South Korean public markets.”

"Building on the foundation established by Parataxis Korea’s Bitcoin treasury, we believe the natural evolution for institutional capital is to further expand into productive digital assets. While Bitcoin serves as the premier store of value, Ethereum represents the engine of the digital economy,” said Michael Lee. “We see South Korea as the ideal market to pioneer this dual-pillar approach. Our mandate is to capture the unique utility and yield-bearing properties of the Ethereum ecosystem to provide our shareholders with diversified and institutional-grade exposure that complements existing digital asset strategies."

In due course, the shares acquired by Parataxis Korea are expected to be transferred among affiliated entities so that the BTC treasury and ETH treasury businesses can be operated in parallel, clearly separated structures.

Parataxis Holdings expects to announce additional details regarding the Transaction after the Company conducts a shareholder meeting, expected to take place in January 2026. Shin & Kim LLC, is acting as legal advisor to Parataxis Holdings in the Transaction.
