What a non custodial crypto swap is and why it matters
A swap where nobody holds your coins in between. Here is how it works, what you give up and what you keep.
Most people meet crypto through a big exchange. You sign up, verify your identity, deposit coins, trade inside the exchange and withdraw later. The whole time the exchange holds your coins. That is custody, and it comes with a long list of things you have to trust: their security, their solvency, and their idea of what to do with your data.
A non custodial swap works differently. There is no balance to keep and no wallet to top up. You send one coin and receive another, in one motion, straight to a wallet only you control.
How the flow works
- You choose what you send, what you want back and how much.
- You paste your own receiving address for the new coin.
- You get a one time deposit address.
- You send the coins. Once the deposit confirms, the coins are exchanged and the result is sent to your address.
The deposit address exists for this single swap. When the swap is done there is nothing left behind, no balance and no account that someone could freeze or leak later.
What you keep
You keep your keys. Your coins sit in your wallet before the swap and in your wallet after it. You also keep your identity out of a customer database, because there is no customer database to sign up for. That is the core reason privacy minded people prefer this model.
What you give up
Honesty matters here. For the minutes the swap takes, your deposit is under the control of the exchange. Deposits are also screened for stolen or sanctioned funds, and a flagged deposit can be held until questions are answered. Non custodial does not mean nobody ever touches your coins. It means nobody keeps them.
You also give up the order book. An instant swap gives you a rate that already includes the margin. SwapPrivate shows the amount after all fees, next to the open market price, so the spread is never hidden. Read more in how it works.
Who it suits
It suits anyone who wants to move between coins without opening an account, people who keep their savings in their own wallet, and anyone who simply does not want to hand over a passport to change Bitcoin into Monero. You can try it right now on the swap page.
Quick answers
Does a non custodial swap mean nobody can ever hold my deposit?
No. The deposit is controlled for the few minutes of the exchange, and a deposit that fails screening can be held. What never happens is a balance kept for you afterwards.
Do I need an account for a non custodial swap?
Not on SwapPrivate. You pick the coins, paste your receiving address, send the deposit and the new coins go straight to your wallet.
