So after a bottle of wine, I decided to create a flat project about flags in the metaverse.
You can find the complete folder here
https://opensea.io/collection/meta-flags
Here are some of the collections flags
The first 10 in the commends that will send me their address will receive the leofra flag.
Leofra
Etheria
Hiveland
For more check the open sea collection or
