Transaction fees, without pretending one number tells the story

Fees pay for an action, not the amount sent

On Ethereum, gas measures the computation a transaction asks the network to perform. A simple transfer uses less gas than a complex smart-contract interaction. The final fee reflects both the work and current network demand, so sending twice as much ETH does not automatically double the fee.

Wallets usually estimate this for you. The number still deserves context: which network is selected, which native asset pays fees, and whether the action is a transfer, swap, bridge, approval, or contract call.

Count the full route

A low-fee network can become an expensive mistake when the receiving service does not support that network. A bridge can add another transaction, another contract, and another waiting period. An exchange withdrawal can add a service fee that is separate from the blockchain fee.

Before moving value, write the route in one line: asset → network → destination → expected arrival asset. If any link is ambiguous, stop and verify it with the receiving service.

• Confirm the same network on both sending and receiving sides.
• Keep enough of the network's native asset for the next transaction.
• Compare the total route, including withdrawal and bridge costs.
• Use a small test transfer when the address or route is new.

Speed is a preference, not a safety signal

A higher priority fee may help a transaction be included sooner; it does not make the destination correct. If a wallet warns that the transaction may fail, investigate the cause rather than repeatedly raising the fee. Failed on-chain transactions can still consume fees because validators performed work.
