ETH to BTC is an asset exchange and a network change. The result targeted by this page is Bitcoin on its own network. WBTC, cbBTC and other representations of Bitcoin on smart-contract networks are different assets with different deposit requirements.
You do not need a theatrical chart to make the distinction. You need a source wallet showing Ethereum, a destination wallet showing Bitcoin and a quote that names the same two endpoints. The route should still make sense after you mentally remove every ticker logo from the screen.
01/BTC means the Bitcoin network here
Open your wallet’s receive flow for Bitcoin and use a supported address it generates. If a platform offers multiple networks for a BTC-labelled asset, select the one matching the provider’s Bitcoin output. Do not infer compatibility from a token name, a logo or a balance shown somewhere else in the wallet.
02/Leave room for the Ethereum transaction fee
Sending ETH uses ETH for gas on the source network. If you enter your entire displayed wallet balance as the amount to exchange, the wallet may need to reserve part of it for the transfer fee. Inspect the wallet’s actual send preview alongside the receive amount shown by ChangeNOW.
03/Arrival and spendability are separate checks
A transaction appearing in an explorer does not automatically mean every receiving service will credit it immediately. Wallets and custodial platforms can have their own confirmation requirements. Follow the provider’s status and the destination service’s deposit policy instead of treating an estimated completion time as a universal deadline.
