This is a special booster collection for https://opensea.io/collection/altocity NFTs in this collection are minted as very limited editions and given away to our community.

This collection was initially published as ERC-1155 contract, it will be replaced with a regular ERC-721 contract instead. Since we revealed the metaverse project, the utility of these NFTs will be changed, so the current owner of a given NFT can customise one of the buildings on the metaverse in the given city.
