According to official news from Odaily Planet Daily, OKX has decided to strategically upgrade X Layer, transforming it into a leading public chain focused on DeFi, payments, and Repository Waivers (RWA) scenarios. Built on Polygon CDK, X Layer completed its "PP upgrade" on August 5, 2025, increasing network throughput to 5,000 TPS, reducing gas costs to near zero, and enhancing security and compatibility with the Ethereum mainnet. The upgrade will also advance ecosystem development, focusing on DeFi, global payments, and the issuance and circulation of Repository Waivers (RWAs). Application adoption will be accelerated through ecosystem funds, liquidity incentives, and infrastructure improvements. OKX Wallet, OKX Exchange, and OKX Pay are fully integrated into X Layer, offering fast, zero-gas withdrawals and an efficient on-chain payment experience.
This upgrade also includes optimizations to the OKB Gas Token economic model. OKB will continue to serve as the sole gas and native token of the X Layer. OKX will destroy 65,256,712.097 OKB from historical repurchases and reserves. Following this, the OKB smart contract will be upgraded to remove the issuance and manual burn functions, fixing the total supply at 21 million. Users holding Ethereum L1 OKB must deposit their assets to OKX and then complete the chain swap via the "Withdraw to X Layer" function. Concurrently, OKTChain will be phased out, ceasing trading on OKX at 2:10 PM (UTC+8) on August 13, 2025. OKT will be periodically exchanged for an equivalent amount of OKB based on the average closing price from July 13 to August 12, 2025. On-chain OKT exchange will continue until January 1, 2026.
