According to Daniel Oon on Twitter, CDK has announced support for the OP Stack and confirmed the removal of the previous 15% tax on transactions (source: Daniel Oon, Twitter, May 7, 2025). This upgrade enhances interoperability with Optimism-based protocols and lowers transaction costs, creating new trading opportunities on decentralized exchanges and layer-2 platforms. Traders should monitor increased liquidity and potential price movements for assets leveraging the OP Stack, as reduced fees may drive higher trading volumes and attract more DeFi participants.
