Dunamu Inc., the operator of South Korea's largest cryptocurrency exchange Upbit, has officially named its new network GIWA Chain following a formal agreement with the Optimism Foundation. Recent reports confirm that Upbit is utilizing the OP Stack software suite to develop this proprietary Layer 2 network, granting the exchange full control over its core rollup architecture. This strategic move makes Upbit the first client on the OP Enterprise self-managed tier, providing direct authority over transaction costs and regulatory adherence. By leveraging the OP Stack, Dunamu can maintain sovereign oversight of GIWA Chain operations while benefiting from Ethereum's robust security. The partnership highlights a growing trend of major exchanges developing proprietary scaling solutions to enhance their service offerings. This development is expected to significantly strengthen the Optimism ecosystem and accelerate blockchain adoption across Asia.
