Decentralized exchanges (DEXs) have transformed the way users trade cryptocurrencies by removing intermediaries and enabling peer-to-peer transactions directly on the blockchain. Unlike centralized exchanges (CEXs), which require trust in a third party, DEXs operate through smart contracts, giving users full control over their assets. One of the most advanced platforms in this space is OKX DEX, now integrated into Tangem Express, offering seamless on-chain and cross-chain swaps with optimal pricing and enhanced security.
This article explores how OKX DEX works, why it stands out as a leading DEX aggregator, and how you can leverage its capabilities within the Tangem Wallet for efficient, secure token swaps across multiple blockchains.
What Is OKX DEX?
OKX DEX is a decentralized exchange and cross-chain bridge aggregator that pulls liquidity and pricing data from over 100 decentralized exchanges across more than ten blockchain networks. With access to over 210,000 crypto assets—including 1,504 newly available tokens for Tangem users—it offers one of the most comprehensive trading environments in DeFi.
At the heart of OKX DEX is the X Routing algorithm, an intelligent system that scans multiple DEXs and liquidity pools to identify the most favorable trade routes. It evaluates factors such as price, slippage, network fees, and bridge costs to deliver the best possible outcome for each swap—whether on-chain or cross-chain.

Key Features of OKX DEX
- Optimal Trading Prices: OKX DEX consistently delivers competitive rates, outperforming other aggregators more than 60% of the time. This eliminates the need for manual price comparisons across platforms.
- Advanced Security Protocols: The platform employs proprietary technology to detect malicious tokens, rug pulls, and inflated burn rates. It also integrates Flash Bot protection, shielding transactions from front-running and minimizing MEV (Maximal Extractable Value) risks.
- Seamless Cross-Chain Swaps: Users can trade assets across more than 20 supported networks—including Ethereum, BNB Chain, Solana, Arbitrum, and Polygon—without leaving the Tangem interface.
How Does Token Swapping Work on OKX DEX?
Token swapping on OKX DEX occurs in two primary forms: on-chain swaps and cross-chain swaps.
An on-chain swap involves exchanging one token for another within the same blockchain network. For example, swapping USDT for DAI on Ethereum. These trades are executed via smart contracts and settled directly on the blockchain.
A cross-chain swap, on the other hand, allows users to convert assets across different blockchains. For instance, sending ETH on Ethereum and receiving SOL on Solana. This requires bridging technology to move value securely between networks.
OKX DEX automates both processes using its X Routing engine, which:
- Aggregates real-time prices from 400+ decentralized exchanges
- Compares liquidity provider (LP) quotes with top-performing pools
- Splits large orders across multiple routes to minimize slippage
- Selects the most cost-effective cross-chain bridge based on transaction size, fees, and slippage tolerance
This ensures users always receive the best net return after accounting for all costs.

Step-by-Step Guide: How to Swap Tokens Using OKX DEX in Tangem Wallet
Performing a token swap via OKX DEX in Tangem Wallet is simple and intuitive. Follow these steps to exchange any supported cryptocurrency:
- Open the Tangem App
Launch the Tangem mobile application and select your wallet card or ring. - Navigate to Your Token Balance
Tap on the token you'd like to swap—for example, USDT. - Initiate the Swap
On the token details screen, tap the Swap button. - Enter Swap Details
Input the asset you want to receive (e.g., AVAX) and specify the amount. - Review Rate Providers
Tangem Express automatically displays the best available rate. Tap the provider name to see alternative options. - Select OKX DEX/Bridge
From the list of providers, choose OKX DEX/Bridge. Grant Token Permission
Tap Give Permission to allow OKX’s smart contract to access your tokens. You can approve either:- A single transaction (recommended for security)
- All tokens (higher risk; use cautiously)
Note: Each permission approval incurs a network fee.
- Confirm Approval
Tap Approve and authenticate using your access code and Tangem card/ring scan. - Adjust Network Fee (Optional)
Tap Network fee to customize gas costs. For fastest processing, stick with the suggested rate. - Execute the Swap
Tap Swap, re-enter your access code, then scan your card or ring to sign the transaction. - Complete the Transaction
Once confirmed on-chain, tap Close. Your swapped tokens (e.g., AVAX) will appear in your balance shortly.
The entire process is non-custodial—your funds never leave your wallet—and powered by decentralized infrastructure for maximum trustlessness.
Frequently Asked Questions (FAQ)
Q: Is OKX DEX safe to use within Tangem Wallet?
A: Yes. All transactions occur through smart contracts without custodial risk. OKX DEX also includes built-in scam detection and Flash Bot protection to guard against MEV exploits.
Q: Do I need to complete KYC to use OKX DEX?
A: No. Since both Tangem and OKX DEX are non-custodial services, no identity verification is required.
Q: Are cross-chain swaps instant?
A: Most complete within minutes, but finality depends on source and destination network congestion and bridge processing times.
Q: Why do I have to pay a fee when granting permission?
A: Approving token access requires an on-chain transaction to update smart contract allowances—this consumes gas like any other blockchain operation.
Q: Can I revoke token permissions after swapping?
A: Yes. You can manage or revoke smart contract allowances using blockchain explorers or DeFi tools that support permission revocation.
Q: What happens if a swap fails?
A: If a trade fails due to slippage or network issues, your original tokens are safely returned to your wallet—minus any gas fees paid.
