Quick Summary
South Korean cryptocurrency exchange Upbit has teamed up with Optimism to create a dedicated Ethereum Layer 2 blockchain named GIWA Chain. This new network will operate under Optimism’s Self-Managed OP Enterprise tier, allowing Upbit to maintain full control over its sequencer and infrastructure while benefiting from technical support and failover protections provided by the Optimism Foundation.
Key Points
- Upbit and Optimism collaborate to build GIWA Chain, an Ethereum Layer 2 chain tailored for Upbit’s needs.
- The Self-Managed OP Enterprise tier enables Upbit to run its own sequencer, controlling transaction ordering and fee collection.
- Optimism provides technical assistance, monitoring, and failover sequencer support to ensure network resilience.
- GIWA Chain has launched on testnet and aims to support Upbit’s expanding blockchain-based financial services.
- Upbit’s parent company Dunamu recently partnered with Hana Financial Group and POSCO International to implement a blockchain remittance system on GIWA Chain.
- The OP Stack ecosystem continues to grow, with other notable projects like Coinbase’s Base also emphasizing operational independence.
Context
Upbit is one of the world’s largest cryptocurrency exchanges by spot trading volume, with over 13 million registered users. As institutional clients increasingly demand control and compliance, Upbit’s decision to operate its own Ethereum Layer 2 chain reflects a broader trend toward self-managed blockchain infrastructure. The sequencer, which orders transactions and collects fees, is a critical component for exchanges serving regulated markets, and Upbit’s setup ensures it retains this authority.
The partnership with Optimism allows Upbit to benefit from the OP Stack technology while maintaining operational control. Optimism’s Self-Managed tier differs from fully managed deployments where the foundation retains sequencer control. To mitigate operational risks, Optimism and Upbit have agreed on a framework that includes monitoring tools, failover sequencers, and priority technical support.
GIWA Chain’s development aligns with recent moves by Dunamu, Upbit’s parent company, to enhance blockchain-based financial services. A trilateral agreement with Hana Financial Group and POSCO International aims to deploy a real-time blockchain remittance system to improve cross-border payments, potentially reducing costs and settlement times compared to traditional systems like SWIFT.
My Take
Upbit’s move to establish a self-managed Ethereum Layer 2 chain signals a cautious but deliberate push toward greater control over blockchain infrastructure by major exchanges. While delegating sequencer responsibilities to third parties can simplify operations, it may not meet the compliance and business requirements of large regulated entities. By leveraging Optimism’s technology yet retaining sequencer control, Upbit balances operational independence with institutional-grade support.
However, operating a sequencer and maintaining high availability for millions of users is complex and resource-intensive. The success of GIWA Chain will depend on how effectively Upbit manages these technical challenges alongside the benefits of reduced fees and faster transactions. It will be interesting to observe how this model influences other exchanges and institutional players considering Layer 2 deployments.
What to Watch Next
- GIWA Chain’s transition from testnet to mainnet and its adoption by Upbit’s user base.
- Progress on the blockchain remittance system involving Dunamu, Hana Financial Group, and POSCO International, especially real-time transaction processing.
- Further developments in the OP Stack ecosystem, including how other projects balance self-management with collective interoperability.
- Potential regulatory responses to exchanges operating self-managed Layer 2 chains.
- Upbit’s broader strategy for integrating blockchain infrastructure into its financial services offerings.
