How can I handle a failed DEX trade in my Web3 wallet?

When trading on DEX using a Web3 wallet, you may encounter transaction failures. There are many possible reasons for transaction failure, such as insufficient fees, insufficient wallet balance, slippage set too low, token risk warnings, or even insufficient market liquidity. To help you quickly identify and resolve issues and complete your transactions, this article summarizes common causes of failure and corresponding solutions, helping you smoothly complete on-chain transactions, enhance your user experience, and ensure the security of your assets.

Unable to trade

1. The contract address or token may cause risks

Reason: If you see a This trade is risky warning during the trade process, because the token contract address has been flagged as a risky address on-chain (such as being suspected of fraud, malicious behavior, or other abnormal activities). To ensure asset security, the Web3 wallet will block related trades.

In addition, if the risk detection feature on the DEX token details page identifies potential risks, it may also result in transaction failure. Note: Token detection data is provided by a third party. This security detection feature is only for evaluating the safety of token, and the detection results may not be completely accurate. These results do not constitute any form of endorsement or recommendation.

Solution: Currently, this token is not supported for transaction within the wallet. We recommend you take the following actions based on your actual situation:

• Contact the Dev: Reach out to the token project team to verify the reason for the transaction restriction.

• Find other platforms: Import your wallet to a third-party platform that supports this network using your seed phrase or private key, or connect to other DApps to try trading.

• Beware of scams: If someone is guiding you to buy this token and you are currently unable to sell it, there may be a risk of fraud. Please stay alert and promptly contact your local law enforcement authorities for assistance in attempting to recover your losses.

Tip: DApp projects are developed by third-party platforms and are not official products of this platform. If you need to perform exchanges within a DApp, it is recommended to first confirm the relevant procedures and risks with the project team.

2. Lack of liquidity

Reason: If you see prompts such as Insufficient liquidity, unable to trade or This trading pair is not currently supported for exchange during the transaction process, it usually means there are not enough buy and sell orders for this token in the current marketplace, so the system cannot complete the matching, resulting in a failed transaction.

Solution:

1. Try in other time: Liquidity is greatly affected by marketplace activity, so it's recommended to try swapping again at different times.

2. View market depth: Before initiating a transaction, check the market depth of the corresponding cryptocurrency to assess the current liquidity situation.

3. Avoid Trade token with poor liquidity: Try to choose mainstream assets with sufficient liquidity to reduce the risk of failed transactions or price slippage.

4. Try other platforms: You can import your wallet into other supported platforms or third-party DApps to try operations

Tip: Web3 wallets are decentralized wallets. The platform cannot guarantee sufficient liquidity for all tokens at any given time; please refer to the trade page for details. DApp projects are developed by third parties and are not official products of this platform. If you need to make exchanges within a DApp, be sure to contact the project to confirm the relevant procedures and risks.

3. Insufficient network fee

Reason: When the network is congested, such as on the Ethereum (ETH) network, gas fees may spike. If the reserved gas fee is insufficient, the transaction may fail.

Solution: If you have relevant assets in your OKX account or other wallets, you may fill up sufficient network fees in order to withdraw from OKX wallet. For more details, please refer to: Wallet Transfer Fees and Supplement Methods

4. Insufficient available balance

Reason: If you see a prompt insufficient available balance during a transaction, it usually means that the available assets in your wallet are insufficient to complete this transaction. If you initiate multiple identical transactions at the same time but only have enough balance for the first one, the remaining transactions will be fail due to insufficient balance.

Solution: Kindly confirm your wallet have sufficient balance. If the balance is insufficient, you can fill up your wallet asset through swaps, wallet receive, or withdrawing from an Exchange. It is recommended to try the transaction again after fill up sufficient balance.

5. Insufficient SOL Rent Recovery

Reason: On the Solana (SOL) network, each account must have a certain amount of SOL deposited as rent to keep the account functioning properly. When exchanging or transferring tokens, your wallet must reserve at least 0.01 SOL to cover rent and trade fees. If your wallet's SOL balance is insufficient, the trade cannot be executed.

Solution: Please make sure your wallet has enough SOL balance. If not, you can top up by withdrawing from an Exchange or transferring from another wallet. We recommend trying the transaction again after topping up. For more details, please refer to: Wallet Transfer Fees and Top-up Methods

Transaction Failed

1. The transaction is in execution

Reason: When the page shows In transaction, it's because the transaction needs to be processed on-chain, and on-chain confirmation usually takes some time.

Solution: We recommend that you patiently wait for the on-chain confirmation to complete. If it takes a long time without success, you may contact us for further assistance.

2. Low Slippage setting

Reason: Slippage is used to allow the transaction price to fluctuate within a certain range. If the slippage set too low, the system will require the execution price to be almost exactly the same as the expected price. However, since market prices fluctuate frequently, if the execution price exceeds the set slippage range, the transaction will not meet the conditions and fail to complete.

Solution: Slippage cannot be completely avoided, but you can reduce the losses caused by slippage, for example:

1. Only trade on platforms with good liquidity and well-developed infrastructure. The best approach is to choose assets with high trading volume and high liquidity.

2. Choose smaller transactions that are easier to fill, rather than placing a large order all at once. If your order exceeds the available liquidity, the DEX won't be able to match your transaction. By breaking a large order into several smaller ones, you're more likely to fill the transactions and reduce the chances of insufficient liquidity.

3. Set the maximum slippage limit. If the actual quantity received is less than the quantity under the maximum slippage limit, the transaction will be canceled to minimize losses.

Do I still need to pay network fees if the transaction fails?

Yes. Regardless of whether the transaction is ultimately successful, as long as a transaction is initiated on-chain (such as sending crypto, contract interaction, etc.), network fee must be paid. This is the cost miners incur for processing transactions, which is unrelated to the wallet platform and cannot be refunded.

Therefore, do not set the network fee too low just to save on transaction fees, as this may cause the transaction to fail or be delayed for a long time due to insufficient fees. If the transaction is blocked, users will still need to pay additional fees to clear the original transaction, which actually increases costs.
