Transaction Fees: Why Might You Be Charged Even If a Transaction Fails?
Transaction fees pay for network processing resources; they do not guarantee that a transaction will succeed.
In One Sentence
On-chain operations often require a transaction fee. The fee unit, payment asset, and calculation method depend on the specific network and operation.
Everyday Analogy—and Its Limitations
It is like paying for computational and processing resources. The limitation of this analogy is that the fee is not necessarily paid to a single company, nor does it mean that the service provider guarantees the transaction will achieve your intended business outcome.
The Correct Concept
Executing a smart contract may consume computational resources. Even if the execution is reverted, the resources already consumed may still incur charges. A platform's withdrawal fee also does not necessarily equal the actual network transaction fee.
Common Misconceptions
The estimate shown by a wallet is not always accurate; setting a low fee may result in delays; and holding the target token does not mean you have the native asset required to pay the transaction fee.
What to Watch Out For
Before signing, review the network, estimated fee, and operation details. If the fee appears unusual, stop and verify the information first. Do not grant authorization through a “fee repair” link provided by a stranger.
