Optimism announced that it is collaborating with Meritz Securities to explore the issuance and circulation infrastructure for South Korean securities tokenization using OP Stack. OP Stack is an open-source technology developed by Optimism for building Ethereum Layer 2 networks, allowing enterprises to create their own blockchain networks compatible with Ethereum.
The collaboration focuses on moving actual securities issuance and distribution infrastructure on-chain rather than merely representing existing securities as tokens. This development is significant as major domestic financial and fintech firms including Upbit, Toss, DB Securities, and KB Securities have been increasingly reviewing OP Stack as a foundational infrastructure for institutional tokenization, positioning it as a potential common rail for South Korea's institutional token ecosystem.
