There are multiple ways to sell your properties.
Your properties are displayed on the virtual world map (https://tilia.earth). When someone clicks on your property, they have a button to make an offer. What we suggest is that you create an account on https://opensea.io linked to your wallet so that you will receive notifications by email if someone places an offer on one of your properties.
You have the ability to list your properties for sale for a fixed price on any marketplace that supports the Polygon network. We usually tell our clients to use OpenSea, as it’s the most popular one.
The price you set for a property is in Ether (the cryptocurrency of the Ethereum network), and there is an equivalent in USD displayed for your convenience.
In both cases, you will receive some Ether in exchange for your NFTs. We will of course help you in the process of selling those Ethers for USD.
We understand that it’s not the most convenient way for our customers, and are already working to allow resale between customers directly in USD from the map. As soon as this feature is live, we plan to make it more appealing to buy properties from our early buyers rather than new properties.
