Pick a species, paint it, give it a hat. It gets its own enclosure and its own coin on pump.fun.
Every buy of an animal's coin drops food in its enclosure. Keep buying and it grows: baby, adult, giant.
Animals are paired with $ZOO, not SOL. Buying any animal buys $ZOO first, and that $ZOO stays inside the animal.
When an animal graduates on pump.fun it walks out of the gates and roams the island. Its $ZOO stays in the pool.
$ZOO is the grass. Grazers eat grass. Predators eat grazers. Every buy at the top runs all the way down.
Animals that graduated on pump.fun. They left the zoo and roam the island, and their $ZOO stays in the pool.
Every animal in the zoo is a pump.fun coin created with $ZOO as its pair instead of SOL. It trades on pump.fun's curve like any other coin and graduates to PumpSwap the same way. The zoo launches it from your wallet with pump.fun's own program; nothing sits in between.
Buying an animal with SOL is one pump.fun swap with two hops: SOL into $ZOO, then $ZOO into the animal. The zoo watches the curve, and every buy drops food in the enclosure. Animals that get fed stay awake. Animals nobody feeds get drowsy, then sleep.
An animal's size is its market cap. Under $25K it's a baby, over $25K an adult, over $250K a giant. When it graduates on pump.fun it leaves the zoo for the wild with a golden coat.
An animal can be paired with another animal instead of $ZOO. A predator paired with a grazer paired with $ZOO: buying the predator buys the grazer, which buys $ZOO. As deep as pump.fun allows.
When you adopt, the species sets the creator fee: small 0.25%, medium 0.5%, large 0.75%, apex 1%. It's paid in whatever the animal eats, to its holders through pump.fun's holder rewards, or to you. The zoo takes nothing.
The zoo has eight districts, and each one starts with four habitats and grows to nine. Enclosures go to the animals being fed, then to the biggest. When a district is full, the animals that don't make the cut wait in the reserve, the wild ground outside the walls, until they're fed back in or an enclosure frees up. Nothing is ever lost: every animal stays on the map and stays tradeable.
The wallet that adopts an animal picks its species, colours, pattern and accessory, and can repaint it later from the keeper page. Designs are signed by that wallet and shown to everyone.
