Upbit launches GIWA Layer 2 for full control over blockchain fees, performance, and compliance.

South Korean crypto exchange Upbit partners with the Optimism Foundation to launch GIWA Layer 2, a proprietary Layer 2 blockchain infrastructure using OP Stack technology. This move gives Upbit full authority over transaction ordering, fee management, and regulatory compliance, enhancing service stability and operational autonomy. GIWA Layer 2 supports Upbit's large global user base by reducing reliance on public blockchains and ensuring institutional-grade performance. The platform operates under a self-managed model, combining Upbit's control with Optimism's technical support, reflecting a broader industry trend toward exchange-owned blockchain networks for better scalability and governance.
