Import your lands

Go back to the Metamask. In the middle section, select NFTs and then click on 'Import NFTs'.

A new screen will appear asking you to enter the contract address and Token ID.

You can find both details on Polygonscan, so enter 0xF4b0c69d94F3A2A26B7E37F9876BaaB99eb4cB77 as the address and the land's TokenID in the appropriate fields, then click 'Add'.

The Land will now appear in your wallet!

Repeat this process for each country you own.
