Before you start

  • A SideSwap wallet with L-BTC, USDt or another asset SideSwap quotes. New here? See Get started.
  • Bitcoin still on the Bitcoin network? Bring it in first with Move bitcoin to Liquid.

Step by step

  1. Open Instant Swap

    Tap Instant Swap at the bottom of the wallet. Before you type an amount, the index price is only an indication. It is not a quote.
    Instant Swap
    Instant Swap with nothing entered, the index price shown as an indicative rate.
  2. Choose the two assets

    Tap the asset under Deliver or Receive to change it. Only assets with a market against the other side are listed. The round button between the two sides flips them.
    Deliver
    The asset sheet for Deliver with Liquid Bitcoin, Tether USD and Blockstream Mining Note.
  3. Enter the amount

    Type the amount or tap MAX. The wallet asks for a firm quote for that size and shows the index price, the quoted rate you get, the fee and how long the quote holds.
    Live quote
    A live quote with Index price, Quoted rate, Fee and Quote expires in 12 seconds, and the Swap button.
  4. Swap

    Tap Swap. The wallet signs and sends the swap. Keep the app open until it finishes. The quote is held for you until then.
    Swapping
    Swapping, with the note to keep the app open while it signs and broadcasts.
  5. Swapped

    The swap settles on Liquid in one block. The wallet shows what left, what arrived, the rate, the fee and your new balance. Tap View in history to find it later.
    Swapped
    Swapped, settled on Liquid in one block, with the rate, fee and new USDt balance.

If a swap does not go through

Not enough

The amount is more than your balance. The wallet shows how much you are short and asks for no quote, so the receive side stays blank rather than showing a figure you cannot get. Lower the amount or tap MAX.

More than your balance, 0.11808 short, with the button reading Not enough L-BTC.

Quote expired

The time to sign ran out before the swap was done. Nothing was swapped and your amounts are kept. Tap Get a fresh quote to try again at the new price, or Change the amount.

Quote expired, with Swapped Nothing and Your amounts Kept, Get a fresh quote and Change the amount.

Good to know

Index price and quoted rate

The index price follows the wider market and is for orientation. The quoted rate is what your swap gets, and every figure in the swap follows it.

Your own price

Want to name your own price? Use the Swap Market, on sideswap.io or in the desktop app.

On a computer

The desktop app has the same Instant Swap. On sideswap.io/instant you can swap with your wallet connected through Liquid Connect and approve the swap in the app.

Still stuck

Look your transaction up first. If it still looks wrong, write to support with the Bitcoin transaction ID.
