Polkacity is an innovative NFT marketplace that aims to revolutionize the ownership of virtual assets by creating the world's first 3D and AR NFT platform across multiple blockchains. Users can purchase and own virtual assets like taxis, gas stations, and services, earning interest on these assets. By holding the corresponding NFTs, users receive weekly payments as the virtual city, which integrates various DeFi elements, continues to grow. Polkacity is expanding its range of available assets to include land and infrastructure. Since its launch at the beginning of 2021, Polkacity has released both a mobile app and a desktop version of its virtual city. In Q3 2021, it introduced its marketplace, allowing users to trade assets. Looking ahead, Polkacity plans to expand to additional blockchains and introduce more NFTs, such as neighboring cities or even entire continents.
