KB Securities teams with Securitize and Optimism on Korean tokenized MMFs
By Crypto Wire
September 23, 2026
KB Securities said on September 23 it signed a memorandum of understanding with tokenization platform Securitize and the Optimism Foundation to pursue tokenized securities (STO) products for Korean institutional investors. Under the split, KB handles product supply using its underwriting, issuance, and sales stack plus institutional clients; Securitize provides tokenization infrastructure; and Optimism supports the blockchain network on OP Mainnet. Digital Today and Seoul Economic Daily match that framing from KB’s announcement.
The Stablecoin Settlement lead is the first product lane: KB plans to introduce a tokenized money market fund (MMF) and tokenized funds using flagship strategies from KB Asset Management for institutions first. WalletInvestor’s Sep. 24 wrap, citing a September 23 release, likewise puts an MMF on OP Mainnet as the debut path and notes Securitize already runs rails used for BlackRock’s tokenized treasury product BUIDL. Treat that as partnership positioning, not a claim that BUIDL itself is migrating to Korea.
What the MOU is—and is not—matters for desks that confuse intent with a live listing. An MOU sets cooperation intent rather than binding launch terms. Korea’s initial regulatory stage for this class of digital securities activity is described in secondary coverage as opening in February 2027, so formal regime go-live is not a same-week event. Near-term work is structuring products, aligning with regulators, and preparing for a market that is not yet fully open under that timeline. Attribute the 2027 window to the WalletInvestor wrap’s regulatory reading; confirm against KB/regulator text before trading on the date.
Sequencing language is not fully locked across channels. Optimism’s X post named a tokenized bond as a first product; its same-day blog pointed to two tokenized funds; KB’s release framed the debut as a tokenized MMF. What stays consistent is the shape: regulated, institution-facing tokenized securities issued through Securitize and settled on Optimism. After the MMF/fund lane, KB says it will consider expanding into stocks, U.S. ADRs, corporate bonds, and Korean government bonds as domestic token-securities rules mature. KB is also reviewing whether to supply Korean institutions with funds Securitize has already tokenized with global asset managers.
Ceremony detail from Seoul Economic Daily: the MOU photo line includes Securitize COO Billy Miller, KB Securities AI & Digital executive Park Jaeman, and the Optimism Foundation COO. Digital Today dates the signing context around September 21 with public disclosure on the 23rd. Those names and dates are desk packaging for the wire; the operational story remains roles, product order, and OP Mainnet settlement—not a guaranteed TVL figure or a retail mint.
Why an NFT and crypto settlement desk opens the wire: tokenized MMF rails sit next to the same institutional cash and RWA questions that moved collectors when BUIDL-style products appeared on other L2s and when Arc gold tokens shipped same-day USDC paths. Landing KB Financial Group’s brokerage arm on Securitize + Optimism is a credibility marker for OP Mainnet in a race where Ethereum L1 and rival chains chase the same issuers. What to watch next: whether the first product is finalized as an MMF, a bond, or both; how Korean regulators sequence the February 2027 phase; and whether any Securitize-tokenized global funds actually clear to Korean institutions. What not to invent: that products are live today, that OP price moves prove institutional inflows, or that the MOU creates exchange-traded exposure for retail NFT wallets.
Bottom line: On September 23, KB Securities, Securitize, and the Optimism Foundation signed an MOU to build institution-facing tokenized securities—led by a planned tokenized MMF on OP Mainnet—with go-live still tied to Korea’s regulatory timetable.
