OKX has expanded its platform with a new in-app decentralized exchange (DEX) trading feature, giving users in the United States, MENA, Southeast Asia, and the CIS direct access to decentralized markets. Announced on November 13, the update allows customers to create passkey-based self-custody wallets and begin trading across Solana, Base, and OKX’s X Layer without relying on external tools.
The feature arrives at a moment when DEX activity is surging, with decentralized exchange volumes reaching a record $613 billion in October and accounting for 20% of overall crypto-exchange volume. OKX says its goal is to make decentralized markets easier to navigate by removing technical friction and simplifying wallet creation.

Once activated, the app automatically generates a self-custody wallet for the user, offering smart order routing across more than 100 liquidity pools and providing live token data and unified portfolio visibility between centralized and decentralized holdings. According to OKX, the new interface is designed to give traders a more seamless on-chain experience. The feature can be enabled through the Explore page or the global search tool inside the app.
Expanding Global Self-Custody Access
With the rollout, OKX is extending self-custody capabilities to millions of users worldwide, though availability depends on local regulations. The passkey-based setup ensures that wallet keys remain fully under user control, aligning with the broader industry shift toward decentralized asset ownership.
Support for Solana, Base, and X Layer at launch also positions OKX to grow alongside high-activity ecosystems. Smart order routing enables the app to pull liquidity from more than 100 pools, helping traders secure more efficient pricing within the DEX environment.

How Users Can Access the New DEX Features
To get started, U.S. users simply activate DEX trading in the OKX App and complete the one-step passkey setup to create their self-custody wallet. DEX tokens can be located through the Explore section, the dedicated DEX category, or the app’s global search bar.
Availability and specific features may vary across jurisdictions, but the core functionality—self-custody and decentralized trading—remains central to OKX’s push to integrate both centralized and decentralized services within a single platform.
