Confirm the pair and the network
Check that both the asset and its network are supported, and that you are sending on the same network the receiving wallet expects. USDT on the wrong chain is the classic mistake.
Swap Box
Sometimes you do not want to deposit to an exchange, place an order, and withdraw just to turn one coin into another. You want to send asset A and receive asset B at a known address. That is the entire job of a swap, and it is what the Swap Box is built around.
ChangeNOW is the non-custodial instant swap we point to here. You do not hand over custody or, for most flows, create an account. The trade-off is that you own every detail: the right network, the right address, the minimums, and the fact that a quote is an estimate until the swap settles.

Route fit
Check that both the asset and its network are supported, and that you are sending on the same network the receiving wallet expects. USDT on the wrong chain is the classic mistake.
A swap quote reflects current conditions. Fixed-rate options reduce surprises, while floating rates can shift between the time you start and the time the swap settles.
When fees and networks matter, the USDT and transfer calculators help you estimate totals before and after the swap so the final amount is not a surprise.
Operator playbook
Most swap horror stories are not hacks. They are a wrong network, an unverified address, or a missing memo. This sequence prevents all three.
Before You Click
Sending the right coin over the wrong chain, or to an address that does not support it, can mean the funds are gone for good. Network selection is the step to slow down on.
Rates and completion times shift when markets and networks are congested. A floating quote at the start is not a guaranteed amount at the end.
Always confirm the receiving address, any required memo or tag, and the exact ticker before you send. There is no undo button on a confirmed transfer.
Straight answers
For most ChangeNOW flows you do not create a traditional account, and the swap is non-custodial, meaning you are not depositing funds into a held balance. You send from your own wallet and receive into your own wallet.
Quotes reflect market conditions at the moment you see them. With floating rates the final amount can change between starting and settling the swap, and network fees are deducted along the way. Fixed-rate options reduce this variation.
Network and address mistakes, not hacks. Sending an asset on the wrong chain, pasting an address that does not match the asset, or skipping a required memo are the usual causes. Verifying both before sending prevents nearly all of them.
Use a swap when you want a quick, direct, non-custodial conversion without order books. Use an exchange when you want order types, deeper liquidity for large size, or you are already keeping funds there. They solve different problems.
