The decentralized finance (DeFi) landscape continues to evolve at a rapid pace, and one of the most significant advancements in recent months is the integration of OKX DEX API into Phantom Wallet, Solana’s leading cryptocurrency wallet. This collaboration marks a major leap forward in user experience, liquidity access, and cross-chain efficiency for millions of DeFi users.
With this integration, Phantom Wallet now offers in-wallet token swaps powered by OKX’s high-performance trading infrastructure. Users can seamlessly trade across multiple decentralized exchanges (DEXs) with optimized pricing, minimal slippage, and lightning-fast execution—all without leaving their wallet interface.

What Is OKX DEX API?
OKX DEX API is a powerful, all-in-one trading aggregator designed for multi-chain and cross-chain transactions. It supports over 20 blockchain networks, including EVM-compatible chains, Solana, and TRON, making it one of the most versatile tools available for developers and platforms building in the Web3 space.
By aggregating liquidity from over 400 DEXs and 18 cross-chain bridges, the API ensures that traders receive the best possible rates across fragmented markets. Its smart routing engine analyzes multiple trading paths in real time, executing trades simultaneously across different protocols to maximize returns and minimize costs.
With an average API response time of just 40 milliseconds—and consistently under 100 milliseconds—the OKX DEX API delivers enterprise-grade speed and reliability. This performance is critical for wallets like Phantom, where fast execution directly impacts user satisfaction and trading success.
Enhanced Trading Experience for Phantom Users
Phantom Wallet, serving millions of users on the Solana network, has long been a gateway to decentralized applications (dApps) and token management. Now, with the integration of OKX DEX API, Phantom elevates its utility by offering:
- Maximum liquidity through aggregated pools across top DEXs
- Reduced slippage and gas fees, especially crucial during volatile market conditions
- Faster trade execution thanks to sub-100ms API responses
These improvements mean users no longer need to manually compare prices across platforms or worry about failed transactions due to poor routing. Whether swapping stablecoins or trading low-liquidity altcoins, Phantom users benefit from smarter, more efficient trades.
Brandon Millman, CEO and Co-Founder of Phantom Wallet, emphasized the significance of this upgrade:
"We’re thrilled to integrate OKX DEX into our swapper, unlocking deeper liquidity, more tokens, and better routes when trading in Phantom. This launch marks a pivotal moment in the evolution of Phantom, allowing our users to access the most competitive rates across DEXs from multiple aggregators—from right inside their wallet."
How Developers Benefit from OKX OS
The OKX DEX API is part of OKX OS, a comprehensive onchain development platform launched by OKX’s Web3 technology arm. Designed to empower developers, OKX OS provides modular tools—including SDKs, APIs, and embeddable widgets—that simplify the process of integrating advanced DeFi features into apps and wallets.
Instead of spending months building complex swap engines from scratch, teams can now launch full-featured token swapping functionality in just weeks using OKX’s battle-tested infrastructure.
Jason Lau, Chief Innovation Officer at OKX, highlighted the broader impact:
"The sheer trading volume being routed through the OKX DEX from Phantom showcases how OKX OS empowers developers to build and scale applications without limitations. We’re excited to see more projects leverage our battle-tested infrastructure to enhance their offerings and deliver improved user experiences across multiple chains."
Today, hundreds of projects are already using OKX OS, collectively processing over 400 million daily API calls. This widespread adoption underscores its reliability and scalability in real-world applications.
