No fee line does not mean free. How to read the gap between the market price and what you actually receive.

What the spread really costs you on an instant swap

Instant swap sites rarely show a fee line. The cost is inside the rate. That is not a trick, it is how the business works, but it makes comparing hard unless you know what to look at.

Three things are inside the rate

  • The margin. The income for doing the exchange.
  • The network fee to send you the new coin, which varies by chain.
  • Market movement during the swap, on a floating rate.

The number that matters

Ignore headline rates. The only number that matters is the amount that lands in your wallet. Then compare that with what the same amount would be worth at the open market price. The gap between the two, as a percentage, is your all in cost.

That is exactly how SwapPrivate shows a swap. You see the amount you receive after all fees, and next to it how far that is from the market, like minus 0.9 percent. No surprises at the end.

What is a fair spread

It depends on the pair and the size. Big liquid pairs like BTC to USDT are usually cheaper than smaller coins. Very small swaps cost more in percentage terms, because the network fee to send you the coins is about the same whatever the amount.

Checking it yourself

Type an amount on the swap page and watch how the spread changes as you go up and down. You will often find a sweet spot where network fees stop dominating. Then compare a few pairs on the pairs page.

Quick answers

Is the market price on SwapPrivate a price I can get?

No. It is a benchmark from public market data so you can measure the rate. Instant swaps price their margin and network fees into the rate.

Why does the amount change with size?

Network fees are roughly fixed per transfer, so they weigh more on small swaps. Larger swaps usually get a better percentage.
