¶ Sweep Private Key
Each bitcoin address is controlled by a private key. The private key is required to spend any bitcoin held in the associated bitcoin address.
Use cases:
-
If you have purchased bitcoin via a bitcoin ATM, some give the option to provide a receipt, printed on which is a private key to allow you to later sweep your purchased bitcoin to an address controlled by your Samourai Wallet. The private key is normally displayed in QR code format.
-
Bitcoin paper wallets are more a thing of the past due to their low security, lack of durability, and difficulty in backing up. You can sweep any bitcoin held by a paper wallet by scanning the private key QR code using this tool.
-
An advanced user may wish to use this feature to send bitcoin between their bitcoin wallets.
How to:
-
Tap Sweep private key
-
Paste the private key into the text field

Note: if the website / service you are trying to authenticate with operates over Tor, ensure you have Tor enabled within your Samourai Wallet network settings before attempting to authenticate with PayNym.
¶ Broadcast Transaction
After a bitcoin transaction is signed, it is usually then automatically broadcasted directly to the bitcoin network. However after signing a bitcoin transaction you may not wish to immediately broadcast it, and instead save the signed transaction in the universally used Hex format for later use.
