When sending crypto from your wallet to an exchange or another wallet, you must pay a network fee. This fee, often called a 'gas fee' or 'miner fee', compensates the network validators or miners who process and confirm your transaction on the blockchain. It is crucial to understand that this fee is paid to the network, not to the platform you are using.
This guide will help you understand what these fees are, how they work, and what to do if you don't have enough to complete a transaction.
What Are Network Transfer Fees?
A transfer fee is a payment made to the decentralized network of computers that secure and operate a blockchain. Every time you initiate a transfer, these computers (miners or validators) use computational power to verify the transaction and add it to the public ledger. The fee is their reward for providing this service and maintaining the network's security and functionality.
Without these fees, there would be no economic incentive to process transactions, and blockchains would not function. The fee amount is not static; it fluctuates based on network demand. When many people are trying to make transactions at once, fees tend to be higher.
How Much Are Withdrawal Fees?
On the withdrawal or 'send' page of your wallet, you will see an estimated fee for the transaction. It's important to note that:
- Fees are charged per transaction, not based on the amount you are sending. Transferring $10 worth of crypto costs the same network fee as transferring $10,000 worth.
- Network fees are highly dynamic. The estimated fee shown is based on real-time network conditions.
- You must ensure your wallet has a sufficient balance of the specific fee-paying asset to cover this cost. If a transaction fails due to insufficient fees, the amount deducted for the attempt is typically non-refundable.
Always double-check the fee estimate before confirming any transaction.
How to Resolve an "Insufficient Fee" Error
If your wallet platform displays an "insufficient fee" or "not enough for transaction fee" error, it means your wallet lacks the necessary cryptocurrency to pay the network miners. To resolve this, you need to deposit the correct native currency for that specific blockchain.
For example, if you are trying to send USDT on the Tron (TRON) network, you will need TRX (Tron's native coin) to pay the fee. The USDT itself cannot be used to cover the cost.
Corresponding Native Coins for Major Networks
Different blockchains have different native currencies that are used to pay transaction fees. Below is a reference table for some of the most common networks.
| Blockchain Network | Native Fee Currency (Gas Token) |
|---|---|
| Bitcoin | BTC |
| Ethereum | ETH |
| X Layer | OKB |
| OKTC (Other chains: X Layer, Ethereum) | OKT |
| Solana | SOL |
| BNB Chain | BNB |
| TON | TON |
| TRON | TRX |
| Aptos | APT |
Note on stablecoins: Assets like USDT and USDC exist as tokens on multiple blockchains. They are not native coins themselves and cannot be used to pay fees. You must always use the native coin of the blockchain the token is on.
How to Add Funds for Transaction Fees
There are two primary methods to get the native coins you need into your wallet to pay for fees.
Method 1: Receive coins from an external wallet
If you hold the required native coin in a different wallet or on another exchange, you can simply initiate a transfer from that location to your current wallet's deposit address. This is the most straightforward way to top up your balance.

Method 2: Withdraw from an exchange
If you have the necessary assets in your account on a centralized exchange, you can use its withdrawal function to send them directly to your Web3 wallet. This is often an efficient way to acquire specific native coins.
- Important Note: Some wallet apps may not have a direct integration for exchange withdrawals. In such cases, you can still use Method 1 by first withdrawing from the exchange to your wallet's public address.
Frequently Asked Questions
Q: What if my exchange account doesn't have the native coin I need for fees?
A: If your exchange account is missing the required asset, you can typically acquire it through the exchange's own services before withdrawing. Most major exchanges offer a "buy crypto" or "C2C" market where you can purchase coins with fiat currency, or a "swap" / "convert" feature to trade one crypto for another.
Q: Are network fees fixed or do they change?
A: Network fees are not fixed. They change constantly based on the supply of block space and the demand for transactions. During times of peak network congestion, fees can rise significantly. The fee you see on your wallet's confirmation screen is the best real-time estimate.
Q: Can I use other assets in my wallet as collateral to pay the fee?
A: No, this is not possible. Transaction fees must be paid in the specific native currency of the blockchain you are using. You cannot pay an Ethereum gas fee with Bitcoin or use a stablecoin like USDT as collateral. The only solution is to acquire the correct native coin.
Q: Why did my transaction fail even though I had some of the fee asset?
A: Transactions can fail if the fee you offered was too low and miners prioritized other transactions, or if the network fee increased suddenly after you initiated the transfer but before it was confirmed. Always ensure you have a buffer of the native coin to account for potential fee spikes.
Q: Who sets the price of the network fee?
A: The fee is determined by the open market on the blockchain. Users who want their transactions processed faster can choose to pay a higher fee, incentivizing miners to include their transaction in the next block. Wallets usually provide a recommended fee based on current network conditions.
Q: Is there any way to avoid high network fees?
A: You can sometimes reduce costs by transacting during off-peak hours when network activity is lower. Some blockchains also inherently have much lower fees than others. Researching and choosing networks known for low-cost transactions can be a good long-term strategy for frequent users.
