Upbit Partners With Optimism to Launch GIWA Chain on OP Stack
Dunamu, the operator of South Korea’s largest cryptocurrency exchange Upbit, has partnered with the Optimism Foundation to build GIWA Chain, an enterprise-focused Layer 2 network built on the OP Stack.
The collaboration positions GIWA Chain as the first self-managed enterprise L2 to launch within the Optimism ecosystem, according to a CryptoBriefing report. Dunamu will operate the chain directly rather than outsourcing infrastructure management to a third party.
GIWA Chain’s technical documentation outlines the project as an Ethereum ETH +0.00% -aligned rollup designed to serve enterprise use cases. By building on the OP Stack, the chain inherits Optimism’s modular architecture and its connection to the broader Superchain ecosystem.
Why the OP Stack Choice Matters for GIWA Chain
The OP Stack is Optimism’s open-source development framework that powers a growing number of Layer 2 networks, including Coinbase’s Base and several other institutional deployments. Dunamu’s decision to adopt it signals a preference for shared infrastructure over building a proprietary chain from scratch.
For Upbit, the move ties South Korea’s dominant exchange to Ethereum’s scaling roadmap. An exchange-operated L2 could eventually streamline settlement, reduce withdrawal fees, or enable new on-chain products for Upbit’s user base, though the announcement has not confirmed specific consumer-facing features.
The partnership also expands the Superchain’s geographic footprint. While Base brought Coinbase’s U.S.-centric user base into the OP Stack ecosystem, GIWA Chain adds a major Asian exchange operator, a development that mirrors the broader trend of exchanges launching dedicated chains, similar to how Western Union recently launched its Solana-based stablecoin USDPT to expand its on-chain presence.
What to Watch After the GIWA Chain Announcement
Several details remain unconfirmed. The announcement has not specified a mainnet launch date, token plans, or whether GIWA Chain will support third-party dApp deployments at launch.
The key questions for observers center on adoption mechanics: whether Upbit will route any exchange activity through GIWA Chain, how developer access will be structured, and what role the chain will play within Dunamu’s broader product ecosystem. As institutional players continue exploring dedicated blockchain infrastructure, developments like these could reshape how exchanges manage liquidity flows and settlement processes.
Dunamu’s annual conference, UDC, has historically served as the venue for major product announcements. Further technical details and partnership specifics may emerge as the project moves toward a public launch, with broader token ecosystem developments potentially shaping how GIWA Chain positions itself within the competitive L2 landscape.
