Announcement on the completion of PP upgrade for X Layer and the launch of OKB Gas Token economic model optimization.
Dear X Layer community members, ecosystem partners, and valued users:
Since the launch of the zkEVM-based public chain X Layer in partnership with Polygon in 2023, OKX has achieved phased results in technical performance and ecosystem development. In the face of the continuous expansion of the decentralized world, OKX has decided to conduct a strategic upgrade of X Layer, aiming to build it into a leading public chain focused on DeFi, payments, and RWA scenarios. The core content and schedule of this upgrade are hereby announced as follows.
Underlying Technology - PP Upgrade
With the strategic adjustment of the Polygon technology stack, X Layer has fully integrated the latest version of Polygon CDK (formerly zkEVM) and completed the "PP upgrade" on August 5, 2025.
Performance Improvement:
Throughput: TPS increased to 5000, meeting the demand for high concurrent transactions.
Gas cost: reduced to negligible levels, enhancing user trading experience;
Security and Compatibility: Maintains higher consistency with the Ethereum mainnet and supports a richer development toolchain.
Ecological Construction Strategy
Key scenarios: focusing on DeFi, global payments, and the issuance and circulation of real-world assets (RWA).
Incentive Program: Establish an ecological fund and liquidity incentives to attract developers and project parties to settle in.
Infrastructure: Improve key components such as cross-chain bridges, oracles, and compliance services to accelerate the implementation of ecosystem applications.
Integration with OKX Wallet, OKX Exchange, and OKX Pay
OKX Wallet
Fully integrated X Layer network, supporting low Gas transactions globally with a rich on-chain ecosystem.
OKX Exchange
Launch 0 Gas Fast Withdrawals: Mainstream assets like USDT can be directly transferred to X Layer with one click, arriving in seconds.
OKX Pay
Default uses X Layer as the underlying public chain for payments, providing a faster, more economical, and more secure settlement experience.
OKTChain delisted
Due to the high overlap in positioning and functionality between OKTChain and X Layer, the X Layer team will gradually terminate the technical maintenance and circulation support for OKTChain. Starting from August 13, 2025, at 2:10 PM (UTC+8), OKT will stop trading on the OKX exchange. At that time, all pending orders with unfinished withdrawals will be automatically canceled by the system.
Starting from August 15, 2025, for users who still hold OKT at that time, the OKX exchange will automatically convert users' OKT into equivalent OKB based on the average closing price of OKB and OKT on the OKX exchange's spot market from July 13, 2025, to August 12, 2025, "average closing price".
OKTChain will continue to operate until January 1, 2026. Before that, on-chain OKT holders can deposit OKT to OKX at any time. The OKX exchange will regularly and automatically convert users' OKT into an equivalent amount of OKB at the average closing price according to the previous rules.
Native Gas Token - OKB Economic Model Upgrade
Gas and Native Token roles: OKB will continue to be the only Gas and Native Token for X Layer.
Starting from the date of announcement, OKB (Ethereum L1 version) will gradually cease to be used. Holders are requested to first transfer Ethereum L1 OKB to the OKX exchange and use the "Withdraw to X Layer" function for one-click chain swapping. In the future, the OKX exchange will no longer support OKB withdrawals to Ethereum L1.
One-time burn of historical repurchase and reserved OKB 65,256,712.097 pieces
OKX will conduct a one-time destruction of the historical repurchase and the reserved 65,256,712.097 OKB, and will switch to automatically destroying all OKB transferred to the black hole address via smart contract. After this operation is completed, we will stop the manual destruction of OKB, and the total issuance of OKB will be fixed at 21 million.
Upgrade OKB Smart Contract
After completing the one-time burn, we will upgrade the OKB Smart Contract to remove the functions of minting and burning.
The specific implementation schedule is as follows:
On August 13, 2025, at 2:10 PM (UTC+8), OKT will stop trading on the OKX exchange, while OKTChain will continue to produce blocks and process on-chain transactions.
On August 13, 2025, at 3:00 PM (UTC+8), the OKX exchange will stop the withdrawal of OKB to ETH L1.
On August 15, 2025, at 10:00 AM ( UTC+8, the platform will automatically convert the OKT in the user's account to OKB according to the rules.
August 15, 2025 2:00 PM ) UTC+8), Burn X OKB in one go, and invoke the smart contract for on-chain destruction.
August 18, 2025 2:00 PM ( UTC+8), upgrade OKB Smart Contract, remove the functions of issuance and destruction.
