Metanaut is the first NFT project initiated by the AIGC core community. It serves as users' 2D and 3D avatar identities and provides different levels of access to AIGC Chain. Metanaut also function as interactive nodes on the test network and play a crucial role in the development of AIGC Chain. As the ecosystem continues to grow, Metanaut will become the starting engine for developing the AIGC community and collective knowledge.
