Optimism Foundation announced the signing of an MOU with Dunamu, the parent company of South Korean crypto exchange Upbit, to jointly develop the GIWA Chain. GIWA Chain is set to be officially launched by Upbit in September 2025 and will be built on Optimism's OP Stack. In this announcement, Optimism emphasized that GIWA Chain is planned to be the first case under the OP Enterprise Self-Managed model, meaning Dunamu/Upbit will independently manage the main sequencer and core network decisions, while Optimism Foundation will provide engineering support, monitoring, backup sequencers, and other infrastructure support. https://(wublock123.com)/news/upbit-optimism-foundation-launch-giwa-layer2-chain-60524
