Polkacity is a non-fungible token (NFT) marketplace that intends to "revolutionize the ownership of virtual goods" by developing the world's first 3D and AR NFT platform that will be based on several blockchains. Users may buy and own virtual cabs, petrol stations, and other businesses, as well as earn interest on their investments. Users earn weekly payouts by holding the NFTs that represent them as the virtual metropolis incorporating various DeFi features evolves. Polkacity is continually increasing its asset base, which currently includes land and infrastructure.Polkacity, which debuted in early 2021, offers a mobile app and a PC version of its virtual city. Polkacity established its marketplace in Q3 2021, allowing inhabitants to swap assets. In the future, the project plans to expand to other blockchains and incorporate more NFTs, such as nearby cities or even continents.
