| This guide explains how you can create a partially signed bitcoin transaction (PSBT) on BTCPay Server and sign and broadcast it with [Sparrow wallet](https://www.sparrowwallet.com/). We use [BitBox02](https://bitbox.swiss/) hardware wallet in this example, but it will work with any other supported hardware wallet. This can be useful if you have an airgapped setup or persons creating the transaction and signing it are different people. | ||
