- OKX upgrades X Layer for faster transactions, lower fees, and stronger security.
- OKTChain is to be phased out, with asset conversions to OKB.
- The OKB token model was revamped with a fixed supply and smart contract changes.
OKX is advancing its blockchain vision with a significant upgrade to its public network, X Layer. Built in collaboration with Polygon, the network first launched in 2023 using zkEVM technology. Now, with the decentralized ecosystem expanding rapidly, OKX has aligned its focus on DeFi, payments, and real-world asset integration.
Before 5 August 2025, Polygon optimized its tech, and the upgrade on that date strengthened X Layer’s foundation for large-scale blockchain applications. The “PP Upgrade” implements a significant boost in networking capability.
The chain now processes 5,000 TPS and handles high usage without any delays. Fees have also come down to a negligible level, further boosting the transaction experience for all users around the world. Security has also improved further, with tighter compatibility with Ethereum’s mainnet and better developer tooling.
Gas-Free Withdrawals Available on OKX Exchange
OKX is focusing its efforts on three key application domains: decentralized finance, cross-border payments, and tokenization of real-world assets. In order to drive adoption, the company is releasing an ecosystem fund and liquidity incentives to draw developers and teams to develop on X Layer.
Infrastructural upgrades are already in process, comprising increased cross-chain bridges for seamless asset movements, enhanced oracle services for accurate on-chain data, and compliance offerings to enable regulated use cases. OKX is further integrating all its product offerings, Wallet, Exchange, and Pay, with X Layer.
The wallet now accommodates low-fee transactions, and the exchange facilitates real-time, gasless withdrawals of large assets. Settlement through OKX Pay reverts to X Layer for quicker and cheaper settlements.
OKTChain Retirement and OKB Model Upgrade
With a large amount of OKTChain’s functionality being redundant with X Layer, OKX will be decommissioning the older network.OKX Exchange will terminate trading of OKT on August 13, 2025. From August 15, the platform will, on a recurring basis, convert OKT balances to OKB according to a predetermined average closing price.
The OKTChain network shall stay operational until January 1, 2026, allowing holders time to migrate. In parallel to the network updates, OKX is rethinking the economic model of the OKB token. OKB will remain X Layer’s gas token and native token, and Ethereum’s L1 version of the token will be discontinued.
A massive burn of 65,256,712.097 OKB from prior repurchases and reserves will set the total supply at 21 million. The enhanced smart contract will eliminate minting and burning capabilities, promoting long-term supply stability. These actions establish X Layer as a high-performance, low-cost blockchain and prepare it to accommodate a new generation of decentralized applications and payment methods.
