Rare Sats

Rare Sats (short for Rare Satoshis) are individual satoshis that hold unique historical, structural, or cultural significance based on their position in the Bitcoin blockchain. The concept was popularized by the Ordinals community, treating some sats as digital collectibles, similar to rare coins in the physical world.
Each satoshi has a unique ordinal number, and some of them fall into specific rarity categories, such as being the first sat of a block, a halving epoch, or even from the genesis block.
Ordinals theory assigns every satoshi a serial number based on mining order.
Rarity is determined through the sattributes, which define different levels of rarity. .
Rare sats can be tracked, inscribed, and traded via compatible wallets and marketplaces.
No added metadata — rarity is based purely on satoshi placement and ordinal theory
Collectible value — driven by community interest, not protocol rules
Native to Bitcoin — all sats already exist; no tokens or modifications needed
Tradable — often inscribed and sold as 1-sat UTXOs with proof of rarity
Rare sats bring a numismatic layer to Bitcoin, turning individual satoshis into collectible artifacts. They blur the line between digital art, on-chain culture, and pure data — showing how deep value can emerge from Bitcoin’s raw structure.
On the homepage page select the Vault and open it by clicking the Vault preview card.
Navigate to the Assets section -> Rare Sats tab, where you will find a list of the available Rare Sats.
To learn more about Rare Sats in the specific UTXO click on the selected UTXO.
UTXO page displays the full list of the contained sattributes, satoshi ranges and rare sats quantity for each separate sattribute.
Select the Rare Sats UTXO, click the “...” button to open the options menu. From the list of actions, click Send.
A modal window will appear, prompting you to input the Recipient Address.
After entering the necessary details, you'll be prompted to select a transaction fee. You can choose from the recommended fee options or input a custom fee.
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.
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.
For efficient storage and use of rare sats we recommend to utilize the Isolate constructor.
After discovering rare sats, you may find it necessary to separate the rare sats from the original UTXO to release the common sats, make them spendable. By default, UTXO containing rare sats marked as unspendable to prevent uncontrolled spend of rare sats. But often rare sats make up a smaller part of UTXO and block a significant amount of BTC balance. To avoid this we strongly recommend to extract rare sats using split UTXO feature.
Before start splitting remember — minimal UTXO size is 546 satoshis. That means you need a UTXO with minimum 1092 sats to split, equivalent to two UTXOs of 546 sats.
➱ To call the Isolate constructor click on Isolate button in the actions menu or on the UTXO page.
Once the chosen UTXO appears in the Inputs column, the constructor automatically splits it in new UTXOs, so that common and uncommon sats are separated. Newly formed UTXOs will be displayed in the Outputs column.
The scale serves as graphic representation of satoshis sequence contained in the UTXO(s) from the Inputs column. Rare sats are marked in blue color, common sats are grey, and gaps display the split spots.
If you want to get more outputs or some UTXOs in Outputs column is bigger than desired, you can continue splitting them.
➱ To split the UTXO from Outputs column select the UTXO and click Split button. (if the UTXO size is less than 1092 sats, the button is not displayed)
➱ Use the split slider to decide the number of sats for new UTXOs and click Split button. (orange color defines the boundaries of the UTXO 1, grey — UTXO 2)
If the selected UTXO contains rare sats they will be also marked in blue color on the split slider.
New UTXOs will be formed and added to the Outputs column.
If you need to combine rare sats from different UTXOs into one, or the results of automatic split does not meet your expectations, use the combine UTXO feature.
➱ To add a new Input to the Isolation constructor click + button.
In the appeared window you can find two types of UTXOs: Uncommon and Common.
Uncommon tab — UTXOs containing rare sats.
Common tab — safe to spend UTXOs with common sats. Such UTXOs may be used to form a new output with rare sats of sufficient size.
For example, we have one UTXO with 282 Pizza rare sats. We want to split this UTXO and get two separate UTXOs with 200 and 82 Pizza sats, but we cannot do it as initial UTXO size is 736 sats, i.e. too small to be divided in two UTXOs.
To resolve this issue we can just add safe to spend UTXO to the Inputs column, providing sufficient sats to form two UTXOs and split 82 Pizza sats to a separate UTXO.
➱ To choose the UTXO click on the specified UTXO, multiselect is allowed. Then click Add button.
The chosen UTXO will appear in the Inputs column.
Then the constructor will automatically form new outputs, but you can manually modify them as desired, by merging all the outputs in one UTXO or combine and split them in UTXOs with customized size.
➱ To call the combine feature click Combine button.
In the appeared window you can find all the outputs.
➱ To combine the outputs click on the specified outputs, multiselect is allowed. Then click Combine button.
Now you get one output with the rare sats combined from different UTXOs
You can also continue with splitting this output to release common sats.
By default, new UTXOs will be sent to your multisig safe address, but it's possible to change 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.
➱ To continue the split click next, choose the fee, review and confirm.
➱ Confirm the creation of transaction in your connected wallet.
➱ Locate this transaction in the Activity -> Queue tab and click on the "Execute" button to start broadcasting of the transaction.
