Deep Dive
1. X Layer PP Upgrade & Smart Contract Finalization (August 2025)
Overview: This was a foundational upgrade to OKX's Layer 2 blockchain, X Layer. It made transactions much faster and cheaper for everyday users, while a one-time token burn permanently locked OKB's supply.
The "PP upgrade," completed on August 5, 2025, integrated the latest Polygon CDK (Chain Development Kit) technology into X Layer. This technical overhaul increased the network's throughput to 5,000 transactions per second and reduced gas fees to near-zero levels. Concurrently, on August 15, 2025, OKX executed a one-time burn of 65,256,712.097 OKB from its treasury and historical buybacks. The OKB smart contract was then upgraded on August 18, 2025, to permanently remove the functions that allow minting new tokens or burning existing ones, cementing the total supply at 21 million.
What this means: This is bullish for OKB because it fundamentally improved the network's utility, making transactions almost instant and extremely cheap. The permanent supply cap introduces a scarcity model similar to Bitcoin, which could support long-term value if demand for the X Layer ecosystem grows.

2. OKT Chain Decommissioning & Asset Conversion (August 2025)
Overview: OKX streamlined its ecosystem by retiring its older OKT Chain, automatically converting all user assets on that chain to OKB on X Layer to simplify the experience.
Due to functional overlap with the superior X Layer, OKX began decommissioning OKT Chain. Trading of the old OKT token ceased on August 13, 2025. Starting August 15, any OKT held in user exchange accounts was automatically and periodically converted to OKB at a fair average price. OKTChain remained operational for users to withdraw other assets until January 1, 2026.
What this means: This is neutral to bullish for OKB. It reduces ecosystem fragmentation, concentrating all activity, developer focus, and liquidity on X Layer. For users, it meant a forced but managed migration to a more efficient network, strengthening OKB's position as the core utility asset.

3. Ethereum L1 OKB Phase-Out (August 2025)
Overview: OKX deprecated the original Ethereum-based version of OKB, encouraging all holders to move their tokens to X Layer to access the latest features and lower costs.
As part of the economic model optimization, OKX announced it would phase out support for the ERC-20 OKB token on the Ethereum mainnet. The exchange stopped supporting withdrawals of OKB to Ethereum L1 on August 13, 2025. Users were instructed to deposit their Ethereum-based OKB to OKX and use the "Withdraw to X Layer" function for a one-click swap to the native X Layer version.
What this means: This is bullish for OKB as it accelerates network adoption. By centralizing activity on X Layer, it increases transaction volume and utility for OKB as the native gas token, which is essential for the health and growth of the Layer 2 ecosystem.

Conclusion
The latest major codebase developments for OKB, culminating in August 2025, were transformative, shifting its core from a simple exchange utility token to the scarce, high-performance gas token of the X Layer ecosystem. This pivot aims to create lasting value through enhanced utility and enforced scarcity. With these foundational upgrades in place, the key question becomes: how quickly will developer and user adoption grow on X Layer to realize this potential?
