+### Exporting the Bitcoin wallet descriptor
+
+First use `swap` or `asb` with the `export-bitcoin-wallet` subcommand.
+
+Output example:
+
+```json
+{"descriptor":"wpkh(tprv8Zgredacted.../84'/1'/0'/0/*)","blockheight":2415616,"label":"asb-testnet"}
+```
+
+The wallet can theoretically be directly imported into
+[bdk-cli](https://bitcoindevkit.org/bdk-cli/installation/) but it is easier to
+use Sparrow Wallet.
+
+Sparrow wallet import works as follows:
+
+- File -> New wallet -> Give it a name
+- Select "New or Imported Software Wallet"
+- Click "Enter Private Key" for "Master Private Key (BIP32)"
