Understanding the Insufficient ETH Balance Error
When using imToken, a popular mobile digital asset management wallet, you might occasionally encounter an error stating that your ETH balance is insufficient during a transfer attempt. This issue can be frustrating, especially when you need to complete a transaction promptly.
The error typically occurs because every transaction on the Ethereum network requires a certain amount of ETH to pay for gas fees—even when transferring other tokens like USDT or ERC-20 assets. If your available ETH balance is too low to cover these fees, the transaction will fail.
Common Causes of the Error
Several factors can lead to an insufficient ETH balance error:
- Low ETH for Gas Fees: You need ETH to pay for transaction costs, regardless of the token you're sending.
- Network Congestion: During times of high demand, gas fees can spike unexpectedly, requiring more ETH than initially estimated.
- Outdated Gas Fee Estimates: The wallet's suggested gas fee might be too low for the current network conditions, causing the transaction to be rejected.
- Pending Transactions: Previous unconfirmed transactions might be locking up a portion of your ETH balance.
Step-by-Step Solutions to Fix the Issue
1. Check Your Current ETH Balance
First, open your imToken wallet and navigate to the Ethereum (ETH) asset page. Verify your available balance. Remember that you must have enough ETH to cover the entire gas fee for the transaction you are trying to execute.
2. Acquire More ETH
If your balance is low or zero, you will need to purchase ETH and send it to your wallet address. You can buy ETH from a reputable cryptocurrency exchange and then withdraw it to your imToken wallet's receiving address. Always double-check the address before confirming the withdrawal.
3. Adjust the Gas Fee Manually
imToken allows users to customize gas fees. If your transaction is not time-sensitive, you can try setting a lower gas fee. However, if the network is busy, a higher gas fee might be necessary to push the transaction through.
- On the confirmation screen before sending, look for an option like "Advanced" or "Gas Fee."
- Adjust the gas price (Gwei) based on current network conditions. You can use a gas tracker website to see recommended rates.
4. Cancel or Speed Up Stuck Transactions
A previous transaction with a low gas fee might be stuck, effectively reserving a portion of your ETH. In imToken, you can often find an option to cancel such a transaction by sending a new transaction with the same nonce and a higher gas fee, or simply by speeding it up. This will free up the locked ETH for new transactions.
5. Verify Network Connection and App Version
Ensure you have a stable internet connection. An unstable connection can sometimes cause errors in balance reporting. Also, check that your imToken app is updated to the latest version from the official app store, as bugs in older versions can lead to miscalculations.
Best Practices to Avoid Future Errors
- Maintain a Gas Buffer: Always keep a small amount of ETH in your wallet (e.g., 0.01-0.05 ETH) to cover unexpected gas fees for future transactions.
- Monitor Network Status: Before making transactions, check Ethereum network status sites to see if gas fees are unusually high.
- Double-Check All Details: Always verify the recipient's address and the amount you are sending to prevent failed transactions and lost fees.

Frequently Asked Questions
Why do I need ETH to send other tokens?
The Ethereum network requires that transaction fees, known as gas, be paid exclusively in ETH. This is a fundamental part of the network's design, so even when sending USDT or any other token, you must have enough ETH to cover the cost of the computational effort needed to process your transaction.
How can I estimate the gas fee for my transaction?
Gas fees are determined by network demand and the complexity of your transaction. imToken typically provides an estimate. For a more accurate estimate, you can use independent Ethereum gas trackers, which provide real-time data on low, average, and high priority fee rates.
What should I do if I have enough ETH but the transaction still fails?
If your balance is sufficient, the failure could be due to other reasons, such as an invalid token contract address, extremely volatile market conditions affecting slippage, or a temporary issue with the imToken service. Check for any error messages and ensure all information is correct.
Is it possible to get a refund for the gas fee of a failed transaction?
No. Gas fees are paid to network validators for processing the transaction attempt, regardless of whether it succeeds or fails. This payment is for the computational resources used.
Can I use a different cryptocurrency to pay for gas fees?
On the Ethereum network, gas fees can only be paid in ETH. This is a non-negotiable rule of the protocol. Other networks, like BSC or Polygon, have their own native currencies for gas (e.g., BNB, MATIC).
How long does it usually take for a transaction to confirm?
Confirmation times vary based on the gas fee you pay. A higher fee typically leads to faster confirmation, often within 30 seconds to a few minutes. A lower fee could mean waiting several minutes or even hours during peak times.
