How to create a single inscription on Gamma

If you’d like to create your own inscriptions on Gamma, several options are available.

You can inscribe a single image, file, or text, inscribe several in bulk, or create a collection mint.

In this article, we will cover individual inscriptions. For bulk inscriptions, please refer to the linked article.

If you want information on creating a collection mint, please see the related article.

To get started, connect your Ordinal-compatible wallet.

Once your wallet is connected, click Create in the top menu, select “Create on Bitcoin” then choose “Create inscriptions”.

You will be taken to this page, where you can choose the type of inscription you want to create. It can be images, files, text, markdown, or even multiple delegates of an existing inscription.

4. Inscription Selection: How the service selects the Bitcoin unit (UTXO) to create the inscription on

1. Address Settings

These settings define where the inscription is sent and where a refund goes if the process fails

Setting	Description	Example/Default
Inscription Receive Address	The Bitcoin address where the final inscription asset will be "airdropped" and held. This address must be compatible with Ordinals (e.g. a Taprootcompatible address)	bc1p... (Ordinal address)
Refund Address	A Bitcoin address where any refundable funds will be sent if the inscription creation process fails (e.g. if the fee is too low and the transaction times out).	bc1q... (Refund address)
Send Options	Choose to send the inscription to a single address or airdrop to multiple addresses (distribute copies)	Send to one address (Selected)

 

2. Inscribe as Children Under a Parent Inscription?

 

Option	Description	Additional Fee
No thanks	Suitable for most standard inscriptions. The inscription will be a standalone asset.	None
Yes, add parent child	Create an onchain association, allowing the inscription to inherit traits or provenance from a designated "parent."	Additional 5,000 sat fee per child

 

3. How Would You Like to Inscribe?

Choose if you'd like to inscribe on any sat (satoshi) or on a special sat that you already own.
 

Option	Description	Additional Fee
Automatic selection	The service automatically chooses a suitable UTXO from your wallet to use for the inscription. Recommended for most users.	None
Reinscribe existing inscription	Overwrite or add data to an inscription that already exists on the blockchain.	Additional 5,000 sat fee
Special UTXO or Custom UTXO	Manually select a specific UTXO to inscribe on. This is for advanced use cases.	Additional 5,000 sat fee

 

4. Add On-Chain Metadata?

Since we are inscribing a single image, you can easily enter the information using a CSV-based method to add metadata.

Option	Description	Additional Fee
No thanks	Suitable for most standard inscriptions.	None
Yes, add metadata	Adds extra data (like properties, creators, or descriptions) to the inscription, which increases bitcoin fees due to the larger transaction size.	Varies (Increases Bitcoin fees)

 

5. Customize Postage

"Postage" is the minimum amount of satoshis that must be kept attached to the inscribed UTXO. This is required to make the inscription valid and transferable
