Most NFT collections start and end with rarity. CryptoCities can grow differently.

Anchor your collection in cities that already mean something - your hometown, places you have visited, locations you would put on a personal map.

Add depth with cities that carry weight - capitals, recognisable names, or feature-rich profiles that rarely come up for sale.

Tie it all together by filling the ten tracks of a set. The strongest collection is the one that covers every angle, not just the rarest piece.
CryptoCities are real places, so a collection can start with meaning rather than rarity. Off-the-beaten-path cities are often the most affordable, and they make every other piece you add feel more personal.
Once you have anchored your collection in places that matter, rarity becomes the next layer. The dashboard ranks cities by current rarity, so when an opportunity comes up - a listing, a quiet sale, a city that rarely trades - you are ready to act.



A city's rarity is built from its features, country, and size. The fewer cities that share a trait, the more it lifts the score - and a city that stacks several rare traits together climbs higher again.
Sets turn a pile of cities into a structured collection - one that grows from a starter set to a full Apex set as you progress.
A complete set is built from 10 cities, one for each of the 10 feature tracks - Civic, Supply, Movement, Building, Grid, Economy, Leisure, Protection, Tech, and Society.
To place a city in a track, the city needs at least one feature in that track. An Industry feature goes in Civic, a Roads feature goes in Movement, and so on across all 10.
Most cities carry features across more than one track, so the same city can usually fit a few different positions. You decide which track to place each city in.
When a city has more than one feature in the same track, then the highest-level feature counts. That's the level the city brings to the track when you put it there.
Once a city is in a track, the track takes that city's level - from 1 (entry-level features) up to 5 (the rarest, top-tier features). Stronger cities push their tracks higher.
The set's tier is the lowest level across all 10 tracks. Lift one weak track and the whole set climbs a tier. Leave a track empty and the set stays below Foundation, no matter how strong the rest is.
Sets climb through five tiers - Foundation (level 1+), Established (2+), Curator (3+), Treasury (4+), and Apex - which is every track at level 5 across the board.
Auto-fill assigns your unused cities to the empty tracks they fit best, maximising your tier in one click. It's a quick way to see how close your wallet already is to the next step up.
A set's tier is set by its weakest track. The best part of the journey is finding the perfect city to raise a track to it's next level.
Every track at level 1 or above.
Every track at level 2 or above.
Every track at level 3 or above.
Every track at level 4 or above.
Every track at level 5.
Start with places that matter, find rare cities as you go, and over time build something complete. The path is yours.
