The service involves inscribing satoshis with unique gold kilobar serial numbers, allowing them to be traded on Bitcoin's Ordinals protocol. This marks the first time physical gold can be minted and traded on the Bitcoin blockchain via the Ordinals protocol. Swarm Markets is a licensed real-world assets platform regulated by German regulator BaFin.
