+- funds are sent to a swap-in address via a swap transaction.

+We use musig2 to aggregate user keys (user being the wallet) and server keys (server being the LSP: the ACINQ node): swap-in addresses are standard p2tr addresses, and

-We don't directly export your extended master private key for security reasons, so you will need to manually insert it in the descriptor.
-You can obtain your extended master private key in [electrum](https://electrum.org/). After restoring your seed, type `wallet.keystore.xprv` in the console to obtain your master `xprv`.
+lighting-kmp provides both a public descriptor and private descriptor for your swap-in wallet.
