# UTXO Management
After discovering Rare Sats or acquiring Ordinals, you may find it necessary to separate them from the original UTXO to release the common sats, make them spendable. By default, UTXO containing uncommon sats are marked as non-spendable to prevent accidental spending of such UTXOs. But often Rare Sats and Ordinals make up a smaller part of UTXO and block a significant amount of BTC balance.
For efficient storage and use of UTXOs with Rare Sats and Ordinals we strongly recommend to utilize **UTXO Management Tool**.
### Split
{% hint style="info" %}
Before start splitting remember — minimal UTXO size supported by the Tool is **546 satoshis**.
Therefore, the UTXO used for splitting must be at least **1,092 sats** — enough to create **two separate UTXOs of 546 sats each**.
If the selected UTXO is smaller than 1,092 sats, you’ll need to **add an additional UTXO as Input** to complete the split.
{% endhint %}
#### ➱ Access the UTXO Management Tool
Navigate to the **UTXO Management** section of the selected Vault.
Click **Add BTC Input** button to call the list of the UTXOs on your Vault.
In the appeared window you can find two types of UTXOs: **Rare Sats & Ordinals and Common**.
{% hint style="info" %}
**Rare Sats & Ordinals** — UTXOs containing **Rare Sats & Ordinals**.
**Common** — safe to spend UTXOs with common sats. Such UTXOs may be used to form Outputs with Rare Sats & Ordinals of sufficient size.
{% endhint %}
#### ➱ Add the Input
Select the UTXO and click **Add** button. You can select multiple UTXOs at once using the multiselect.
There’s another way to add a UTXO as an input.
Find the desired asset in the **Ordinals** or **Rare Sats** tab, open the action menu, and click **Isolate**. The UTXO containing that asset will be automatically added as an Input.
#### ➱ Split the Input
Once the UTXO added in the **Input(s) column**, the Tool **automatically** splits it in new UTXOs, so that common and uncommon sats are separated.
Newly formed UTXOs will be displayed in the **Output(s) column.**
The scale serves as graphic representation of satoshis sequence contained in the UTXO(s) from the Output(s) column. **Rare Sats & Ordinals** are marked in blue color, common sats are grey, and gaps display the split spots.
#### ➱ Manual Split
If you want to get more outputs or some newly formed UTXOs are bigger than desired, you can continue splitting them.
To split the UTXO from Output(s) column select the UTXO and click **Split** button.
{% hint style="info" %}
If the UTXO size is less than 1092 sats, **Split** button is not displayed.
{% endhint %}
Use the split slider or the input to decide the number of sats for new UTXOs and click **Split** button.
New UTXOs will be formed and added to the Output(s) column.
### Combine
If you need to combine Rare Sats or Ordinals from different UTXOs into one, or the results of automatic splitting don't meet your expectations, use the **Combine** tool.
> For example, we have one UTXO with 300 Nakamoto sats. We want to split this UTXO and get two separate UTXOs with 50 and 250 Nakamoto sats, but we cannot do it as initial UTXO size is 999 sats, i.e. too small to be divided in two UTXOs.
>
>
>
> To resolve this issue we can add **UTXO with Common sats** to the Input(s) column, providing sufficient sats to form two UTXOs and split 50 Nakamoto sats to a separate UTXO.
>
> 
#### ➱ Add the Input
To add a new Input click **+** button.
In the appeared window select the UTXO and click **Add** button. You can select multiple UTXOs at once using the multiselect.
Once the added UTXO appeared in the Input(s) column, the Tool automatically forms new Outputs, but you can **manually modify** them as desired.
{% hint style="info" %}
* Use **Arrow** button to change the order of the Inputs.
* Use **Trash bin** button to remove the unnecessary Input.
{% endhint %}
#### ➱ Combine the Outputs
Click **Combine** button to merge the outputs**.**
In the appeared window you can find the previously formed Outputs.
To combine them click on the specified Outputs, multiselect is allowed. Then click **Combine** button.
Now we have one Output combined from 2 UTXOs.
A newly formed UTXO is enough size to be split into two: one containing **50 Nakamoto sats**, and the other **250 Nakamoto sats**.
Therefore, we’ll use the **Split** to form the two desired UTXOs.
New UTXOs will be added to the Output(s) column.
### Finalize Split & Combine
#### ➱ Transaction Creation
By default, new UTXOs will be sent to your Vault address, but it's possible to change the Recipient. Addresses can be set separately for each UTXO.
To change the recipient of the specified UTXO clear the input and enter the new address in the **Recipient input**.
Click **Next**, select a transaction fee. You can choose from the **recommended fee options** or input a **custom fee**.
#### ➱ Transaction Review and Confirmation
Once the fee is set, you'll be able to **review** the transaction details. If everything is correct, click **Confirm** button and confirm the transaction in the connected wallet.
#### ➱ Transaction Execution
Before the transaction is executed, it must be **signed by the required number of Vault owners**. Once the confirmation threshold is reached, locate this transaction in the **Transactions** section -> **Queue** tab and click the **Execute** button to start broadcasting of the transaction.
