On August 16, 2025, the latest developments of OKX and its native Token OKB mainly focus on the following aspects:

### 1. **Large-scale destruction of OKB and fixed supply volume**
- OKX completed a one-time burn of **65,256,712.097 OKB** (worth approximately **$7.6 billion**) on August 15, permanently reducing the total supply from about **87 million** to **21 million**, aligning with Bitcoin's scarcity model.
- After the burn, the price of OKB soared to **142 USD** (an increase of over 170%), and then fell back to the **100-109 USD** range, with trading volume surging by **13,000%**.

### 2. **X Layer Upgrade and OKTChain Retirement**
- **X Layer** (zkEVM chain based on Polygon CDK) has completed the "PP upgrade", increasing to **5,000 TPS**, with gas fees reduced to nearly zero, and optimized Ethereum compatibility.
- **OKTChain** has stopped trading (August 13), and the remaining OKT will be automatically converted to OKB at the average price from July 13 to August 12 (completion on August 15). OKTChain will be completely shut down on January 1, 2026.

- On August 18, OKX will upgrade the OKB smart contract, **removing the issuance and burning functions**, permanently locking the supply.
- The Ethereum L1 version of OKB will be gradually phased out, and users need to bridge to X Layer via OKX.

- OKX plans to launch an **ecosystem fund** and liquidity incentives, and integrate OK
