OKX Unveils Public Chain Upgrade for DeFi and Payments

OKX has made a major shift with the public launch of its X Layer blockchain, focusing on driving growth in decentralized finance (DeFi) and payment applications. This upgrade went live on August 5, 2025, after a significant technological leap impacting the entire ecosystem. Key highlights include a fixed OKB supply of 21 million tokens, contributing to deflationary tokenomics, and the phasing out of the OKTChain network and its associated tokens. The update promises increased transaction speed and reduced costs for users, marking a major departure from previous iterations.
