South Street at dusk — the Kerbside world engine
The national address ledger, made collectible

Own the street you love.

Every Australian address can hold exactly one card, ever — a stylised streetscape artwork permanently anchored to its place in the national ledger. Discovered free, bought known-item, traded on our market. We never print; Australia does.

Genesis mints — South Street, Strathfield 2135

The first three cards on the ledger. Rarity is cosmetic only — tier, atmosphere and treatments are seeded fate, never market data.

Live world — Three Streets · production engine

South Street, Wallis Avenue and Strathlora Street on real cadastre, running on real Sydney time and live weather. Minted plots stand in full 3D; everything else stays a plot — unrevealed fog or surveyed board — until its card exists.

The ledger

One card per address, ever.

15.1 million mintable principal addresses. Supply events come only from reality — quarterly address births, extinctions, successions. Eras are vintage stamps, never editions.

The hunt

All chance is free. Every purchase is known-item.

Prospecting reveals a card's complete fate before any payment. Nothing is ever sold unseen, and reveal points can never be bought.
