The decentralized finance (DeFi) landscape continues to evolve at a rapid pace, driven by strategic collaborations that enhance user experience, security, and efficiency. A prime example of this innovation is the recent integration between 1inch and OKX, two leading forces in the Web3 ecosystem. This partnership brings the powerful 1inch Swap API and 1inch Fusion API directly into OKX Wallet and OKX DEX, offering users seamless, secure, and optimized crypto swapping capabilities across multiple blockchain networks.
This integration marks a significant milestone in OKX’s mission to deliver cutting-edge Web3 tools that simplify access to decentralized finance. By leveraging 1inch’s advanced API infrastructure, OKX enhances its wallet and decentralized exchange offerings with deeper liquidity, better pricing, gasless transactions, and robust protection against malicious trading behaviors like MEV (Maximal Extractable Value) attacks.
Enhanced Swapping Experience Through Advanced APIs
At the core of this collaboration are two of 1inch’s most sophisticated technologies: the Swap API and the Fusion API. Together, they form a comprehensive solution that optimizes every stage of the swap process — from route selection to execution security.
The 1inch Swap API: Smarter Routes, Better Rates
The 1inch Swap API is engineered to deliver optimal trading outcomes by aggregating liquidity from numerous decentralized exchanges and protocols across major blockchains. When a user initiates a swap on OKX Wallet or OKX DEX, the API scans hundreds of potential trading routes in real time, identifying the most cost-effective path with minimal slippage and reduced gas consumption.
This means users no longer need to manually compare prices across platforms. Instead, they benefit from automatically optimized trades that maximize returns — whether they're swapping stablecoins, blue-chip tokens, or emerging altcoins.

The 1inch Fusion API: Next-Gen Flexibility and Security
While the Swap API focuses on efficiency, the Fusion API introduces groundbreaking features that redefine convenience and safety in DeFi transactions:
- Gasless Swaps: One of the biggest barriers for new users entering DeFi is the need to hold native tokens (like ETH) just to pay for transaction fees. With Fusion, users can execute swaps without holding network gas tokens. Professional market makers known as resolvers cover the gas costs, removing friction and enabling smoother onboarding.
- Built-in MEV Protection: Front-running and sandwich attacks are persistent threats in decentralized trading. The Fusion API combats these risks by encrypting trade details until execution, ensuring that orders cannot be exploited by bots or miners. This design-first approach to security gives users peace of mind with every transaction.
- Customizable Trade Parameters: Advanced traders can set specific price thresholds and time windows for their swaps, allowing greater control over execution conditions. This level of customization supports strategic trading while minimizing exposure to market volatility.
These capabilities make the Fusion API particularly valuable for both casual users seeking simplicity and experienced traders demanding precision.
Why This Integration Matters for Web3 Adoption
OKX has long been committed to building intuitive, high-performance tools that bridge traditional crypto users with the broader Web3 world. The integration of 1inch APIs strengthens this vision by embedding enterprise-grade DeFi infrastructure directly into consumer-facing products.
Users of OKX Wallet — a non-custodial wallet supporting multi-chain asset management, dApp access, staking, and trading — now enjoy an upgraded swapping experience without leaving the app. Similarly, traders on OKX DEX, the platform’s decentralized exchange interface, gain access to deeper liquidity pools and smarter routing logic powered by 1inch’s aggregation engine.
This synergy not only improves performance but also reinforces trust. By partnering with a battle-tested DeFi innovator like 1inch, OKX demonstrates its dedication to security, transparency, and long-term sustainability in the decentralized ecosystem.
Frequently Asked Questions (FAQ)
Q: What are APIs, and how do they improve my crypto swapping experience?
A: APIs (Application Programming Interfaces) allow different software systems to communicate. In this case, 1inch’s APIs enable OKX Wallet and DEX to access advanced swap routing, better prices, and enhanced security features without building the technology from scratch.
Q: Do I need to do anything to use the new 1inch-powered features?
A: No action is required. The integration is seamless — all OKX Wallet and OKX DEX users automatically benefit from improved swap rates, gasless options, and MEV protection when available.
Q: Are gasless swaps really free for me as a user?
A: While you won’t pay gas fees directly in your wallet, the cost is factored into the overall swap price through resolvers. The tradeoff is increased convenience and accessibility, especially for users who don’t hold native chain tokens.
Q: How does MEV protection work in practice?
A: The Fusion API uses encrypted order submission and time-locked execution to prevent third parties from seeing your trade details before confirmation. This stops front-running bots from exploiting your transaction.
Q: Is my private key still secure with this integration?
A: Yes. All swaps remain self-custodial — your keys never leave your device. The APIs enhance functionality but do not compromise control or security.
