How to use Trust Wallet's built-in DEX?

Understanding Trust Wallet’s Built-in DEX

1. Trust Wallet integrates a decentralized exchange (DEX) directly within its mobile application, allowing users to swap cryptocurrencies without leaving the app. This functionality is powered by aggregating liquidity from various decentralized exchanges across blockchains. The integration simplifies the trading process while maintaining user control over private keys and funds.

2. The DEX feature supports multiple blockchain networks, including Ethereum, Binance Smart Chain, Polygon, and others. This multi-chain support enables users to trade tokens across different ecosystems seamlessly. Each transaction occurs directly from the user’s wallet to the selected decentralized exchange’s smart contract, ensuring non-custodial security.

3. Before using the DEX, users must ensure their wallet contains sufficient native tokens for gas fees on the respective network. For example, swapping BEP-20 tokens requires BNB in the wallet to cover transaction costs. Without adequate gas tokens, swaps will fail.

4. The interface displays real-time exchange rates, slippage settings, and estimated transaction times. Users can adjust slippage tolerance manually, which is crucial during periods of high volatility. Higher slippage may result in less favorable rates but increases the likelihood of transaction success.

5. Trust Wallet does not charge additional fees for DEX swaps beyond what the underlying protocols and blockchain networks require. However, users should be aware of potential price impact on low-liquidity tokens, which can lead to significant deviations from expected output amounts.

Step-by-Step Guide to Executing a Swap

1. Open the Trust Wallet app and navigate to the “Swap” tab located in the main menu. This section automatically detects the user’s current network and displays available trading pairs based on connected blockchains.

2. Select the token to be swapped by tapping the “From” field. A list of supported assets in the wallet appears, showing current balances. Choose the desired token and enter the amount to trade. The app dynamically calculates the estimated output.

3. Tap the “To” field and choose the destination token. The platform suggests popular pairs but allows searching for any compatible token by symbol or contract address. Users must verify the correct contract to avoid scams.

4. After confirming both tokens and amounts, the app presents a preview screen showing exchange rate, network fee, slippage, and estimated completion time. Review all details carefully before proceeding.

5. Confirm the transaction by tapping “Swap.” The wallet prompts for authentication via biometrics or password. Once approved, the transaction is broadcasted to the blockchain and can be tracked through the integrated explorer.

Security Practices When Using the DEX

1. Always double-check token contracts when entering them manually. Fraudulent tokens with identical names but different addresses are common. Use only verified sources for contract information.

2. Enable wallet security features such as PIN protection, biometric authentication, and recovery phrase backup. Never share the recovery phrase with anyone, especially through digital channels.

3. Avoid using public Wi-Fi when conducting swaps. Unsecured networks increase the risk of session hijacking or man-in-the-middle attacks. Use a trusted mobile connection or secured private network.

4. Monitor transaction history regularly for unauthorized activity. Although Trust Wallet does not have access to funds, malware on the device could compromise private keys.

5. Be cautious of phishing attempts that mimic the DEX interface. Only download Trust Wallet from official sources like the Apple App Store or Google Play Store.

Frequently Asked Questions

What happens if a swap fails?Failed swaps typically result from insufficient gas, high slippage, or network congestion. The funds are not lost; they remain in the wallet. The gas fee is still deducted because the transaction was processed by the network.

Can I swap NFTs using the built-in DEX?No, the current DEX integration only supports fungible tokens. NFT transfers and trades must be conducted through dedicated NFT marketplaces accessible via the browser within Trust Wallet.

Why are some tokens not appearing in the swap list?Tokens may not appear if they are not listed in the wallet’s token registry or if they belong to an unsupported network. Users can manually add tokens using the contract address, provided the network is active in the wallet.

Is there a minimum or maximum amount for swaps?There is no universal limit imposed by Trust Wallet. However, individual decentralized exchanges and liquidity pools may enforce minimum input amounts or maximum trade sizes based on available liquidity.
