ASSA aims to establish a novel on-offline linkage model that seamlessly connects physical and online spaces through the metaverse, specifically in the realm of music. This innovative ecosystem will serve as an enjoyable playground for all participants, enabling them to conveniently utilize community and commerce features based on their individual requirements. Additionally, users will be rewarded and able to share profits based on their contributions. Moreover, we will introduce Sing to Earn and Entertain to Earn initiatives, directly linking recreational and cultural creative activities to economic endeavors.
