Sending a small amount of a token can involve a fee that feels surprisingly large. The network is not necessarily charging a percentage of the amount you send. Its fee model may reflect the work required and demand for processing.
On Ethereum, gas measures computational work, while the amount paid depends on the applicable fee mechanism. A simple transfer and a complex contract interaction can require different work. Other networks and additional layers use different arrangements, so this explanation should not be applied blindly to every wallet.
Read the whole confirmation
Identify the network, asset being transferred, fee asset and estimated total. Check whether the screen also includes an exchange, bridge or service charge. A platform’s withdrawal fee is not always the same as the underlying network cost.
Keep enough of the required fee asset for the action if the network requires it. Owning a token does not automatically mean the wallet can pay for moving it. Do not send more funds merely because an unknown “support” account tells you a fee is needed to unlock a balance.
Failure can still consume resources
Some unsuccessful on-chain operations still incur fees because processing work was performed. A rejected action before submission and a transaction executed but reverted on-chain are different situations. Use the transaction record and the relevant network documentation to understand which occurred.
Before retrying, check whether the first transaction is pending, completed or failed. Repeatedly submitting without understanding the state can create additional costs or duplicate actions. A low fee estimate is not a guarantee of prompt execution.
This is transaction literacy, not an investment recommendation. The safest useful habit is to understand what you are authorising before confirming an irreversible action.
