What exactly does your wallet call ether?
| Displayed position | Establish before requesting a KAS quote | Why the distinction matters |
|---|---|---|
| Native ETH on the selected chain | The transferable amount and the matching funding network | This is the balance you must identify for a native-ETH payment |
| WETH token | Whether the chosen route explicitly accepts that token | An ERC-20 representation is not interchangeable with a native-ETH deposit instruction |
| ETH shown under another network tab | Which chain actually holds the funds you can send | A matching ticker does not establish a matching deposit network |
| Combined portfolio value | The individual assets and accounts behind the displayed valuation | The total cannot be entered as if it were spendable ETH |
WETH needs its own asset check
Ethereum documentation distinguishes native ETH from WETH, an ERC-20 representation created through a wrapping contract. Their relationship does not make every receiving instruction accept both. If your balance is WETH, do not transfer it to an instruction labelled only for native ETH without establishing explicit support for that asset and network.
Any operation needed to prepare native ETH is separate from this exchange. Review that operation in the wallet or service you use, including its own fee and outcome. Only calculate the final funding amount once the intended balance is actually transferable. Do not assume a portfolio label, a token logo or a previous successful swap establishes what a new deposit instruction can receive.
A small ETH balance needs two amount checks
- The wallet must be able to submit the payment
- Ethereum gas fees are paid in ETH. Read the fee shown for the intended transfer and the amount the wallet will let you send. Do not copy the whole displayed balance into a payment form and then assume the fee is covered elsewhere. The usable amount depends on the actual transaction review.
- The exchange must accept the amount you fund
- Compare that transferable amount with the current route limits. A preliminary calculation made from the gross wallet balance may no longer describe the payment you can make after the wallet’s fee. If the amount is unsuitable, reassess before sending rather than relying on a guessed adjustment to the eventual KAS payout.
- The receiving account must match the KAS instruction
- Open the intended Kaspa receiving account independently of the ETH sender. Check its receiving details against the payout destination. The sending wallet’s gas estimate is not the receiving account’s deposit policy, and neither should be used as a substitute for the current exchange instruction.
ETH balance questions before buying KAS
- Can I pay for this ETH exchange by sending WETH instead?
- Only use an asset explicitly supported by the current funding route. WETH is a token representation, while the instruction may expect native ETH. If you hold a different asset, resolve the asset and network selection first. Sending it to see whether the exchange detects it is not a compatibility check.
- Why is the maximum send amount smaller than my ETH balance?
- The wallet may need to account for the outgoing transaction fee. Inspect its actual review screen rather than deriving the sendable amount from a portfolio valuation. Recheck the exchange limits and the KAS calculation using the amount you can fund, with the sender’s fee kept separate.
