Creating a Hot Wallet

A hot wallet is connected to the internet and is suitable for regular transactions.

1. Start a New Wallet:
   • Go to File > New Wallet.
   • Name your wallet (e.g., Hot Wallet) and hit Create Wallet.
2. Configure Wallet Settings:
   • Choose Single Signature.
   • Select Native SegWit for efficiency and low fees.
   • Under Keystore, choose New or Imported Software Wallet.
   • Generate a new set of words (12 or 24) and write them down securely.
3. Secure Your Backup:
   • Confirm the backup by reentering the words.
   • Consider using a metal backup solution like Billfodl for durability.

Creating a Cold Wallet

A cold wallet is stored on a hardware device, providing added security for your Bitcoin.

1. Connect Your Hardware Device:
   • Plug in your hardware device (e.g., Trezor Model T) and unlock it.
2. Create a New Wallet in Sparrow:
   • As with the hot wallet, go to File > New Wallet.
   • Name it (e.g., Trezor T) and select Create Wallet.
   • Choose Single Signature and Native SegWit.
   • Under Keystore, choose Connected Hardware Wallet.
   • Scan or connect your device and import the keystore.

Creating a Multi-Signature Wallet

Multi-signature wallets require multiple keys for transactions, enhancing security.

1. Set Up Multi-Signature Configuration:
   • Go to File > New Wallet.
   • Name it (e.g., MultiSig Wallet).
   • Choose Multi-Signature and configure (e.g., 2 of 3 signers).
   • Select Native SegWit.
2. Add Signers:
   • For each signer, choose the appropriate option (connected hardware, air-gapped, etc.).
   • Import the keystores from your different hardware devices.
   • Ensure each device is aware of the multi-signature wallet by exporting and importing the relevant files or QR codes.
3. Complete the Setup:
   • Once all signers are added, apply and finalize the setup.

Sending and Receiving Transactions

1. Receive Bitcoin:
   • Navigate to the Receive tab.
   • Generate a new address and share it or the QR code to receive funds.
2. Send Bitcoin:
   • Go to the Send tab.
   • Enter the recipient address, label, and amount.
   • Adjust the fee based on urgency.
   • Create the transaction and confirm.
   • For a multi-signature wallet, sign with the required number of devices.

Connecting to Your Own Node

For privacy and self-sovereignty, connect Sparrow to your own Bitcoin node.

1. Access Settings:
   • In Sparrow, go to Preferences > Settings.
2. Configure Server Settings:
   • Toggle off the public server.
   • Enter your node’s information (IP address and port or Tor address).

   • Test the connection to ensure it's successful.
   • If connected, the server indicator will turn blue.
