Have you ever wanted to ready-player one yourself? Soon you’ll be able to make an ultra-HD scan of yourself and your real-world assets and move everything into the metaverse.

Metahero brings to the market 3D scanning and modeling technology that generates ultra-realistic 3D avatars and virtual items to be used across games, VR, social media, and online fashion. The tech also allows for the creation of NFTs from real-world works of art and collectibles.

We have partnered with the world leader in 3D scanning: Wolf Studio. Their cutting-edge technology was extensively tested and used by big industry names; Most recently, CD Projekt created characters for their hot new release, CyberPunk 2077.

We’re merging this powerful tech with a marketplace and a novel deflationary token-based ecosystem to offer users, gamers, artists, and entrepreneurs direct access to virtual opportunities of the future. Wolf Studios’ genius and next-generation technology coupled with our expertise in building tech startups from the bottom up will make Metahero one of the hottest projects of 2021/2022.
