Swaptopia is in beta and opens on mainnet, where a swap moves real bitcoin. Swap only amounts you can afford to lose, or test a swap on signet first with test bitcoin.

What Swaptopia handles for you
- A wallet of your own: Swaptopia creates a wallet in your browser the first time you open the page, and signs every swap with its keys.
- Bitcoin to Lightning: Swaptopia boards the bitcoin you send onto Ark, then pays the Lightning invoice or Lightning address you give it.
- Lightning to bitcoin: Swaptopia receives your Lightning payment, then offboards the sats to the on-chain address you paste.
Before your first swap
- Back up your seed phrase. Swaptopia shows it only until you confirm the backup. Nobody can recover your sats without it.
- Keep the tab open during the stages that ask for it. If you lose the tab, reopen the same page in the same browser to carry on with the swap.
- Check the amount limits. On mainnet, a bitcoin-to-Lightning swap starts at 51,000 sats or more.
