Optimism Partners with South Korea's Largest Exchange for GIWA Chain Development

A significant collaboration has been announced in the cryptocurrency infrastructure field, as Optimism (OP) Foundation partners with Dunamu, parent company of South Korea-based exchange Upbit, to develop GIWA Chain.

The project was first announced by Upbit in September 2025 and is built on Optimism's OP Stack infrastructure. As part of the partnership, Dunamu and Upbit will operate the network's primary sequencer while maintaining control over core decision-making mechanisms.

In a self-managed model, the Optimism Foundation will provide engineering support, system monitoring, and backup sequencer infrastructure. According to Minseok Jung, COO at Dunamu, operating GIWA Chain is a strategic step for Upbit, allowing users to benefit from performance and regulatory standards compatible with existing platforms.
