Major Binance-Listed Altcoin to Partner with South Korea’s Largest Cryptocurrency Exchange

In a significant development for the cryptocurrency ecosystem, the Optimism Foundation has joined forces with Dunamu, the parent company of prominent South Korean exchange Upbit, to drive the development of GIWA Chain. This strategic partnership, formalized through a memorandum of understanding, was revealed following Upbit's initial announcement of the project in September 2025. By leveraging Optimism's OP Stack infrastructure, GIWA Chain is poised to become the inaugural application to debut under the "OP Enterprise Self-Managed" paradigm.

Under this novel framework, Dunamu and Upbit will assume responsibility for the network's primary sequencer, while also retaining oversight of key decision-making processes. Meanwhile, the Optimism Foundation will provide comprehensive technical support, including system monitoring and backup sequencer infrastructure, to ensure the seamless operation of GIWA Chain. According to Dunamu's Chief Operating Officer, Minseok Jung, the deployment of GIWA Chain represents a calculated move for Upbit, aimed at delivering high-performance capabilities and adherence to regulatory standards that align with its existing platforms. By adopting the self-managed model, Jung emphasized that the company can harness the benefits of a proven infrastructure while maintaining operational autonomy.
