## Welcome to Kaos City

Kaos City is a click-to-earn, on-chain game built on the Base network where you play with digital characters, battle enemies and earn the in-game currency **KAO**. Inside the platform you can convert between **USDC** and KAO, use KAO to grow your team, and – if you wish – swap your KAO back to USDC through our Vault.

This whitepaper gives a high-level overview of how Kaos City works, how players progress, and how the in-game economy is designed.

### What you can do in Kaos City

* **Build your squad**\
  Acquire character eggs, open them to reveal a random rarity, and assemble a roster of up to four fighters.
* **Battle and earn KAO**\
  Spend stamina to fight enemies with different win rates (90%, 70%, 50% or 30%) and receive KAO when you win.
* **Progress and upgrade**\
  Heal damaged characters, use the breeding system to combine three characters of the same rarity into a higher-rarity one, and push your team to higher earning potential.
* **Enter and exit through USDC**\
  Deposit **USDC on Base** into the Kaos City Vault, play using KAO inside the game, and when you decide to withdraw, convert KAO back to USDC with a platform fee on withdrawals.
