• Securing a Competitive Moat Through Traditional Finance Principles and Global Partnerships
• Deploying GK8-Powered Cold Wallets to Deliver Bank-Grade Security
• Unlocking High-Utility Use Cases in Payments and Remittances via KRW1

“Our objective is to fuse the institutional stability of traditional finance with the cutting-edge infrastructure of global blockchain leaders, driving ‘Anchorage Digital’-level scaling within the domestic market.”

Met at the BDACS headquarters in Gangnam, Seoul, CEO Harry Ryoo presented a sharp contrast to the typical crypto backdrop. Rather than the ubiquitous t-shirts and hoodies of the blockchain world, Ryoo was dressed in a tailored corporate suit.

“Our dress code might seem a bit unconventional for this space,” Ryoo remarked with a smile. “However, as a digital asset custodian entrusted with safeguarding client wealth, we believe aligning our operational presentation with that of traditional tier-1 banks and securities firms is foundational to fostering institutional trust.”

BDACS’s presence in the South Korean digital asset custody sector is expanding rapidly. As of March this year, the firm’s assets under custody (AUC) surpassed 80 billion KRW, commanding a dominant 26%+ market share of the nation’s total institutional digital asset custody volume.

Legal-First Leadership: “Custody as the Gateway to Institutional Crypto”

BDACS was established following the acquisition of D-Custody, a venture originally formed in 2021 by Woori Bank and Coinplug. Post-acquisition, Woori Bank remains a principal shareholder, ensuring that institutional governance, banking-grade compliance, and stability remain embedded in BDACS’s DNA.

Co-founders CEO Harry Ryoo and CSO Terry Kim are both veteran attorneys who spent nearly a decade collaborating at a premier law firm before continuing their partnership at BDACS. Ryoo noted that their extensive track record in digital asset legal advisory and regulatory framework design allowed them to develop a unified, cohesive strategy regarding the exact infrastructure required to meet institutional regulatory standards.

Ryoo recalled their early days of establishing global institutional connections, traveling across the United States to participate in high-level ecosystem events. Both co-founders, who hold advanced degrees from the US, headed straight to the epicenter of digital asset innovation to align their vision with tier-1 global partners, including Ripple and Galaxy Digital.

Reflecting on the company’s genesis, Ryoo observed, “The domestic market is rapidly integrating into the institutional financial fold. We choose to view the evolving regulatory landscape as a major market opportunity rather than an operational burden.” He emphasized that amid shifting frameworks and macro volatility, custodians who strictly adhere to rigorous institutional compliance will inevitably serve as the primary gateway for the digital asset economy.

Frontlining Bank-Grade Security Powered by Galaxy Digital Technology

A key driver of BDACS’s market momentum is its full-scale deployment of core infrastructure from GK8, the premier custody technology subsidiary of the Nasdaq-listed Galaxy Digital. GK8’s institutional offering is frontlined by its proprietary offline cold wallet architecture and its Unlimited Multi-Party Computation (uMPC) hot wallet solutions.

Detailing the security of the GK8 cold wallet infrastructure adopted by BDACS, Ryoo emphasized, “The core engineering principle is the absolute elimination of attack vectors. The architecture ensures that the private keys are entirely isolated and never exposed to the internet at any point in their lifecycle.”

He provided a highly intuitive analogy to describe the mechanics: “Standard exchange wallets or retail hot wallets essentially store keys inside an internet-connected device. In contrast, our cold wallet functions like a high-security physical vault deep underground. The key never leaves the secure room; the external system simply generates a transaction voucher, which is passed one-way to be authorized.”

He continued, “First, the internet-connected external environment specifies the transaction details, including the destination and the amount, on a digital voucher. This data travels via a strict one-way unidirectional rail into the isolated vault. Inside, an air-gapped device cryptographically signs the transaction in a manner analogous to physically stamping a document, and only that signed voucher is broadcast back to the external environment.”

“The external server then submits this fully signed voucher to the blockchain network to execute the transfer. Throughout this entire sequence, the vault holding the private keys maintains zero connectivity to the internet,” Ryoo added.

Pioneering the Korean Equivalent of ‘Anchorage Digital’

Further solidifying its market-first position, BDACS recently introduced KRW1, a pioneering stablecoin designed to maintain a strict 1:1 peg backed by fiat Korean Won deposits. As regulatory frameworks mature, the KRW1 project is uniquely positioned to unlock diverse utility across commercial payments, cross-border remittances, and institutional on-chain finance.

“In the long run, a highly trusted, compliant KRW-backed stablecoin must take root within South Korea’s institutional framework,” Ryoo stated. “Our target blueprint is an institutional-grade infrastructure giant like Anchorage Digital in the US, which is a venue that simultaneously satisfies stringent regulatory demands and uncompromised security protocols.” He explained that the KRW1 ecosystem is fundamentally engineered to serve as a high-throughput payment rail bridging traditional and decentralized financial systems.

Ryoo’s mid-to-long-term roadmap for BDACS centers on hosting custody, stablecoin issuance, and tokenization capabilities on a single, unified institutional-grade platform. By leveraging GK8’s elite custody tech to safeguard assets and combining it with proprietary stablecoin infrastructure, BDACS is systematically positioning itself as Asia’s leading full-stack digital asset infrastructure provider.

“Surpassing 80 billion KRW in AUC is just the foundational phase,” Ryoo concluded. “We will continue to scale our business model, seamlessly compounding custody, stablecoins, and tokenization infrastructure through deep partnerships with traditional finance and global blockchain institutions.”
