KB Securities, Securitize, and Optimism sign MOU for tokenized securities in Korea

KB Securities, one of South Korea’s premier brokerage houses, has formally partnered with Securitize and the Optimism Foundation to build tokenized investment products for institutional clients in the Korean market. The memorandum of understanding was signed on September 21 and announced publicly two days later.

The initial product lineup will include tokenized money market funds and a fund built around strategies from KB Asset Management. Settlement will run on the OP Mainnet, Optimism’s Ethereum-compatible Layer 2 network. For KB Securities, this represents a first foray into tokenization.

What the partnership actually looks like

The division of labor is clean. KB Securities handles issuance and distribution to its institutional client base. Securitize provides the tokenization platform and serves as transfer agent. The Optimism Foundation manages the underlying blockchain infrastructure on OP Mainnet.

Future phases of the partnership envision tokenized stocks, American depositary receipts, corporate bonds, and Korean government bonds. Those expansions depend on regulatory developments in South Korea, which has been slowly building a framework for digital securities since 2023.

The choice of OP Mainnet is notable. Operational since December 2021, the Layer 2 network has been positioning itself as enterprise-grade infrastructure. In July, DB Securities signed a separate MOU focused on security token offerings and real-world asset projects built on the OP Stack, specifically targeting Jeju-based issuances.

Why Korea, why now

For Securitize, Korea represents a logical next step in geographic expansion. The firm has tokenized over $5B in assets under management as of July, making it one of the most established players in the space. It recently completed a public listing through a SPAC merger.

There’s also a notable corporate connection worth flagging. Hanwha Group, one of South Korea’s largest conglomerates, holds an approximately 9.7% stake in Securitize.

The bigger picture for tokenized securities

The OP Mainnet’s growing roster of Korean partnerships suggests Optimism is building something of a beachhead in the country’s institutional finance ecosystem. Two major brokerage MOUs in roughly two months indicates a deliberate strategy rather than opportunistic deal-making.

The regulatory contingency attached to the more ambitious products, tokenized stocks and government bonds, is the variable worth tracking. South Korea’s financial regulators have shown willingness to evolve their frameworks, but the pace of that evolution will ultimately determine whether this partnership produces a handful of tokenized MMFs or a full-spectrum digital securities ecosystem.
