The POLC token is the native asset of Polka City, an NFT platform where users can invest in virtual assets in the form of a virtual city. Users can purchase and own virtual taxis, gas stations, and services, earning interest on their assets. By holding the NFTs representing them, users receive weekly payments as the virtual city grows, incorporating various DeFi elements. Polka City is continually expanding its available assets, which now include land and infrastructure.
