The decentralized finance (DeFi) landscape continues to evolve at a rapid pace, driven by seamless integrations, enhanced user experiences, and infrastructure that empowers developers to build at scale. A major milestone in this evolution is the integration of our DEX API into Phantom Wallet, one of Solana’s most widely used crypto wallets. This collaboration brings powerful, optimized token-swapping capabilities directly into the hands of millions of users.
Our DEX API is an all-in-one trading aggregator designed for multi-chain and cross-chain transactions. It leverages smart routing technology to execute trades across multiple decentralized exchanges (DEXs) simultaneously—ensuring optimal pricing, minimal slippage, and zero fees. Now, with its integration into Phantom Wallet, users can enjoy faster, more efficient swaps on the Solana network and beyond.

Seamless Integration, Superior Performance
Phantom Wallet’s adoption of our DEX API highlights the growing demand for enterprise-grade DeFi infrastructure that delivers speed, reliability, and deep liquidity. Built on battle-tested architecture, the DEX API supports 20+ blockchain networks, including EVM-compatible chains, Solana, and TRON—making it one of the most versatile trading solutions in the market.
By aggregating liquidity from over 400 decentralized exchanges and 18 cross-chain bridges, the API ensures users access the best available prices across the entire DeFi ecosystem. With API response times consistently under 100 milliseconds—and an average of just 40 milliseconds—trades are executed swiftly, enhancing user experience and reducing missed opportunities due to price volatility.
This level of performance is critical for wallets like Phantom, which serve millions of active users who expect fast, secure, and cost-effective transactions. The integration enables Phantom to offer:
- Maximum liquidity through aggregated pools across top DEXs
- Reduced slippage and gas costs, especially during high-market volatility
- Near-instant trade execution thanks to ultra-low latency routing
These benefits are powered by our intelligent smart routing engine, which evaluates thousands of potential trade paths in real time to identify the most efficient route for each swap.
Empowering Developers with OKX OS
The DEX API is a core component of OKX OS, a comprehensive developer toolkit launched on September 30 to accelerate onchain innovation. OKX OS provides developers with modular tools—including APIs, SDKs, and embeddable widgets—that simplify the process of integrating advanced DeFi features into their applications.
With OKX OS, projects can launch full-featured decentralized trading experiences in just weeks, rather than months. The platform handles complex backend operations such as liquidity aggregation, cross-chain routing, and real-time price discovery—freeing developers to focus on user experience and product differentiation.
Hundreds of projects are already leveraging OKX OS to scale their offerings, processing more than 400 million API calls daily. This widespread adoption underscores the toolkit’s reliability, scalability, and ease of integration.
Why This Integration Matters for DeFi
The Phantom Wallet integration is more than just a technical upgrade—it’s a signal of maturation in the DeFi space. As user expectations rise, platforms must deliver seamless, high-performance experiences that rival centralized services while preserving decentralization.
By using a single API to access multi-chain liquidity and smart routing, Phantom was able to rapidly enhance its feature set without building complex infrastructure from scratch. This model exemplifies how modern DeFi development should work: modular, interoperable, and developer-friendly.
Moreover, the success of this integration demonstrates the value of standardized, high-quality infrastructure. Instead of every wallet or dApp reinventing the wheel, they can now plug into proven systems that offer better results with less effort.

Frequently Asked Questions
Q: What is a DEX API?
A: A DEX API (Decentralized Exchange Application Programming Interface) allows applications to connect to multiple decentralized exchanges programmatically. It enables features like token swaps, price quoting, and liquidity access across chains without requiring direct integration with each exchange.
Q: How does smart routing improve my trades?
A: Smart routing analyzes multiple trading paths across various DEXs and liquidity sources in real time. It splits orders when beneficial and selects routes with the best price and lowest fees—maximizing output and minimizing slippage.
Q: Is the DEX API available for other wallets or dApps?
A: Yes. The DEX API is open for integration by any project—wallets, dApps, or platforms—looking to add multi-chain swap functionality. It supports SDKs, APIs, and embeddable widgets for flexible implementation.
Q: Does using the DEX API incur additional fees?
A: No. The DEX API itself charges zero fees. Users only pay standard network gas costs and any fees imposed by the underlying DEXs or protocols facilitating the trade.
Q: Which blockchains does the DEX API support?
A: The API supports over 20 networks, including Ethereum, Solana, Binance Smart Chain, Arbitrum, Optimism, Polygon, TRON, and other major EVM and non-EVM chains.
Q: Can developers use OKX OS for free?
A: Yes. Developers can start using OKX OS at no cost. It includes free-tier access to the DEX API and other tools needed to build and scale onchain applications.

The Future of Onchain Trading
As blockchain ecosystems grow more interconnected, the need for unified, high-performance trading infrastructure becomes increasingly clear. The integration between our DEX API and Phantom Wallet sets a new standard for what users can expect from decentralized wallets—speed, efficiency, and access to deep liquidity across chains.
For developers, this marks an opportunity to innovate faster and deliver better products by leveraging battle-tested infrastructure instead of building everything in-house. With OKX OS powering more projects every day, we’re moving toward a future where onchain applications are easier to build, more reliable, and more accessible than ever before.
Whether you're a developer looking to integrate swaps into your app or a user seeking smoother DeFi experiences, the tools are now available to make it happen—with speed, security, and simplicity at the forefront.
