Unspent outputs (also known as a UTXO) are what make up the bitcoin balance in your wallet. Your wallet fundamentally is a software for managing these unspent outputs. Samourai Wallet allows you to manage these outputs on a granular level (also known as coin control) but also handles them by default in a privacy preserving manner.
Each UTXO has a number of attributes:
txid)Notes containerAny output that is in your wallet that is associated with the transaction will share the same note. This makes it easier to avoid spending these outputs together again.
You can force the wallet to only use the selected output in a subsequent transaction.
You can toggle an output between "Unspendable" and "Spendable" at any time.
Outputs marked as "unspendable" will not be used to compose transactions, and will not be used to total your balance. They will be hidden until marked "spendable".
There are circumstances where you may quickly require an individual private key for an active address in your wallet.
The private key will be displayed to you in both text and QR code form.
Please be aware that the private key grants access to the bitcoin on that address and should never be shared with anyone!
The list of current unspent outputs contains a list of addresses that can sign messages in your wallet.
The Batch Spend feature allows users to combine (or batch) multiple unrelated spends into one single transaction that gets broadcasted to the network. The benefit to creating these combined transactions is much lower overall fees and more efficient use of blockchain space. It has been estimated that users can save up to 80% on bitcoin miner fees by using the Batch Spend feature.
The batch spend feature is useful for anyone who needs to send bitcoin to more than one other party in a given time frame. For example, if I want to pay both Alice and Bob, it would make more sense for me to use Batch Spend and pay them both at the same time for 1 transaction fee instead of initiating two separate transactions and paying both transaction fees.
Batch spend is only available from the Deposit account
