At the moment, OpenBazaar only uses Bitcoin.
Bitcoin is by far the largest cryptocurrency in use, and as such the core development team has focused on it entirely.
However, others are welcome to incorporate altcoins into OpenBazaar with one of two methods:
- Submit a pull request to the main GitHub repository which enables use of an altcoin.
- Fork the repository to create an altcoin specific OpenBazaar clone.
Please remember that an altcoin must have multisignature capabilities in order to use the OpenBazaar platform. Integrating an altcoin into the OpenBazaar code would be a significant task, and we recommend reaching out to the core developers before starting.
