A city NFT (non-fungible token) is a digital asset. Each city NFT uniquely represents a virtual ownership certificate for a single real-world city. A city NFT is being owned by one person only. Since city NFTs adhere to the ERC721 standard for digital assets, they can be purchased and traded on OpenSea.io.
Setup a digital wallet (e.g., MetaMask), purchase cryptocurrency ETH (Ethereum) with debit card or Apple Pay in MetaMask, register at OpenSea.io and connect your digital wallet with your OpenSea account. Now you are all set to make an offer for your favorite city NFT on OpenSea.io.
Each city is assigned a significance, ranging from 1 star with low significance to 5 stars with high significance. Significance is determined based on population size, cross-regional political influence, and popularity. The higher the significance of a city, the more prominently it is displayed on the map. For example, 5 star cities are already displayed if the whole world is visible. 1 star cities are only visible after zooming in closely to the city's region.
Cities are handpicked and added step by step until the limit of 10.000 cities is reached.
No. City NFTs represent symbolic ownership certificates. Holders of city NFTs have no rights or obligations towards the real-world cities, nor can they make claims of any kind against the real-world cities.
