# Multi-Mint

**What Is Multi-Mint and How Does It Work?**

\
Multi-Mint is a cross-protocol minting feature that allows users to mint assets from multiple Bitcoin protocols within a single minting flow. Supported combinations include Runes + Alkanes and brc-20 + Runes + Alkanes.

\
The underlying mechanism works as follows: Alkanes inscription data is compatible with the Runes protocol, allowing both types of data to be embedded in the same `OP_RETURN` output. This `OP_RETURN` output can then be included in a brc-20 inscription transaction.

\
As a result, a single transaction can mint assets from two or three protocols simultaneously, with confirmations occurring in the same block whenever possible.

\
As a general reference:

🔸 Runes + Alkanes: around 35% smaller combined transaction size

🔸 brc-20 + Runes + Alkanes: around 45% smaller combined transaction size<br>

**Why Multi-Mint?**

Compared with separate minting, Multi-Mint provides:

✅ Mint across two or three protocols within one transaction

✅ Fewer repeated steps and a smaller combined transaction size

✅ Lower network fees and reduced UTXO usage, especially during repeat mints

✅ Same-block confirmations whenever possible

\
Two modes are currently available:

🔸 Runes + Alkanes

🔸 brc-20 + Runes + Alkanes

To use Multi-Mint, select one of the supported combinations, choose the target asset under each protocol, and set the Repeat Mint quantity.
