Ethereum

A wallet or service may show a fee estimate, but gas cost and processing depend on the transaction and network conditions. Review the destination, asset, network, and total debit; use the current wallet preview rather than an old fee or timing estimate.

On Ethereum, a transaction can transfer ether or interact with a smart contract. Network computation is measured in gas, and the fee is paid in ETH. Contract interactions can use a different amount of gas from a simple transfer, so a single quoted fee is not a permanent price for every transaction.

A transaction can remain pending while it awaits network inclusion, and the displayed status may change as it is processed. Save the transaction hash and check it with a trusted block explorer or the wallet's own activity view. A pending or failed status is not the same as a confirmed transfer to the intended recipient.

For a payment to an exchange or merchant, the receiving service may require a particular network or additional account reference. Ethereum-compatible token networks are not automatically interchangeable. Compare the deposit instructions with the sending screen before authorizing anything.

Before you send

• Confirm the asset and destination address
• Match the network on the sending and receiving screens
• Review the current fee estimate and total debit
• Keep the transaction hash and verify its status

Common costly errors

• Sending an asset over an unsupported network can prevent crediting
• Network fees can change with demand and transaction complexity
• A copied address should be checked before signing; transfers may not be reversible

Open the current send preview and compare asset, network, address, fee, and total before confirming.
