OKX's mission is to make global markets accessible through reliable and transparent technology.

The built-in "DEX Trading" in the exchange further expands on this foundation by combining the efficiency of centralized infrastructure with the openness of decentralized networks.

Starting today, the built-in "DEX Trading" is officially launched on the OKX App, including in the United States and major regions worldwide. Users can directly access decentralized markets on Solana, Base, and X Layer without leaving the OKX ecosystem.

Lowering the Barriers to Decentralized Access

For most users, accessing DEX markets typically requires multiple wallets, frequent network switches, managing mnemonic phrases, and performing token cross-chain operations for gas fees. Each step can introduce friction, delays, and risks.

With the built-in "DEX Trading," users can initiate DEX trading in one step. The system automatically creates a self-custody wallet and secures it with a Passkey, eliminating the need to manage mnemonic phrases. Users have complete control over their private keys and assets while being able to directly access on-chain liquidity.

More importantly, users can directly use their existing OKX exchange account balance to explore the DEX market. This integration eliminates the cumbersome processes of manual transfers or cross-chain operations—OKX App seamlessly handles settlements between centralized and decentralized environments.

Unified Interface and Smart Pricing

The built-in "DEX Trading" integrates the functionalities of CEX and DEX into a unified, streamlined interface. Users can freely switch between centralized order books and decentralized liquidity within the same portfolio view.

Our smart order routing system can search hundreds of liquidity pools in real-time to find the optimal trading path. This provides CEX-level speed and reliability while maintaining the transparency and coverage of DEX.

Early Market Access and Transparency

Many new projects launch on DEX before entering CEX. With the built-in "DEX Trading," OKX users can access these early markets on Solana, Base, and X Layer using the same account system as centralized trading. Every on-chain transaction is verifiable, auditable, and fully controlled by the user.

Design Principles

The design of the "Exchange Built-in DEX" revolves around the following engineering priorities:

• Unified Access — Achieving CEX and DEX trading through the same balance and interface.
• Self-Custody — Wallets are owned and controlled by the user.
• Security through Simplicity — Using Passkey authentication instead of mnemonic phrases.
• Transparent Execution — All on-chain operations are verifiable.
• Interoperability — Supporting Solana, Base, and X Layer (with partial regional support).

This design reduces operational complexity while expanding access to decentralized liquidity and early token ecosystems.

OKX's "Exchange Built-in DEX" represents an evolution in how the crypto market operates: it is a modular system where the efficiency of centralization coexists with the freedom of decentralized access. By connecting user balances, providing a unified interface, and enabling self-custody, we are moving towards a fully interoperable financial architecture—where access is determined by technology rather than intermediaries.
