As a comprehensive, multichain, cross-chain decentralized exchange aggregator, OKX DEX leverages advanced routing technology to deliver optimal trading outcomes across a vast network of decentralized exchanges (DEXs).
With support for 20+ blockchains, integration with 400+ DEXs, and access to over 3 million crypto assets, OKX DEX consolidates liquidity like no other platform.

Start Trading on OKX DEX
Before diving into swaps or cross-chain transfers, ensure your wallet is connected. Once logged in, navigate to Wallet > Trading to access the core trading interface. Here, you'll find two primary options: Swap & Bridge and Limit Order.
The Swap & Bridge function allows instant token exchanges within the same blockchain or across different ones. Meanwhile, Limit Order gives you greater control by letting you set specific price targets for future trades — ideal for strategic entry and exit points.
Leverage your digital assets more effectively through seamless trading experiences powered by deep liquidity and intelligent routing.
How to Use Swap & Bridge
OKX DEX currently supports crypto swapping across 26 chains and cross-chain bridging on 17 major networks. This broad compatibility ensures users can move value freely between ecosystems such as Ethereum, BNB Chain, Solana, Arbitrum, Optimism, and more.
Performing a Swap (Same-Chain)
A same-chain swap lets you exchange one token for another without leaving the current blockchain. It's fast, simple, and perfect for portfolio rebalancing or taking profits.
- Under the From field, select the token you wish to trade and enter the amount.
- In the To field, choose the desired output token.
- Review the estimated output, price impact, and network fee.
- Click Swap to proceed.
- Confirm transaction details on the summary screen, then click Confirm Swap.
If your wallet lacks sufficient gas fees in the native token (e.g., ETH on Ethereum), OKX DEX offers a convenient solution:
- Select Approve [Crypto]
- Choose Fund [Crypto]
- Use Swap with Gas — a recommended feature that automatically converts a supported asset into the required gas token
This eliminates the need to pre-fund your wallet separately, streamlining the user experience especially for newcomers.
Executing a Cross-Chain Bridge
Cross-chain transfers are essential in a fragmented blockchain landscape. OKX DEX simplifies this process by integrating top-tier bridging protocols like cBridge, MultiChain, and SWIFT, enabling secure and efficient asset movement between chains.
To bridge tokens:
- Enter the amount under Pay (source chain) and verify the expected Receive amount (destination chain).
- Choose Cross-Chain Swap.
- Select your preferred bridge route using the dropdown menu in the X Routing section.
- After reviewing fees, slippage tolerance, and estimated arrival time, click Confirm Swap.
You retain full control over which bridge to use, allowing you to prioritize speed, cost, or reliability based on your needs.
Note: Some low-liquidity tokens may require higher slippage tolerance — typically 5% or more — to prevent transaction failure due to price volatility or insufficient reserves.

Optimize Your Trades with X Routing
At the heart of OKX DEX’s performance is X Routing, an advanced algorithm that scans multiple DEXs and liquidity sources across chains to identify the most efficient trade path.
Instead of settling for suboptimal prices on a single exchange, X Routing splits large orders intelligently across various platforms and pools. This not only improves execution prices but also reduces market impact and slippage — crucial advantages when trading high-value or less liquid assets.
You can manually select your preferred route via the dropdown in the X Routing section, giving experienced traders transparency and control over their execution strategy.
