BRC-20

BRC-20 is a fungible token standard for Bitcoin built on top of ordinals. This standard defines three basic functions: deploy, mint and transfer.

To obtain the current account balance and token supplies of BRC-20 assets a BRC-20 indexer is required. Multiple online services provide this information. One of the most popular is called UniSat, where you can verify account balance and asset information. This indexer is open-sourced.

Deploy BRC-20​

To create a new BRC-20 asset, create an inscription with the content defining protocol (p) as brc-20, operation (op) as deploy, asset ticker (tick), maximum supply (max), and optional limit per mint (lim) depending on your preference. For example:

{ 
  "p": "brc-20",
  "op": "deploy",
  "tick": "ordi",
  "max": "21000000",
  "lim": "1000"
}
danger

Before deploying a new asset, make sure that the ticker has not been used before. In other cases, deployment will be considered invalid.

Mint BRC-20​

To mint a BRC-20 asset, create an inscription with the content defining protocol (p) as brc-20, operation (op) as mint, asset ticker (tick) and amount (amt) depending on your preference. For example:

{ 
  "p": "brc-20",
  "op": "mint",
  "tick": "ordi",
  "amt": "1000"
}
danger

Before doing the mint operation, check that the asset you are trying to mint is still available and that you are not minting more than the allowed maximum.

Transfer BRC-20​

To transfer the BRC-20 asset, create an inscription with the content defining protocol (p) as brc-20, operation (op) as transfer, asset ticker (tick) and amount (amt) depending on your preference. For example:

{ 
  "p": "brc-20",
  "op": "transfer",
  "tick": "ordi",
  "amt": "500"
}
