# What is NostraCity?

**NostraCity** is a ground-breaking passive income protocol on the Avalanche Network, focused on sustainability through external investments.

NostraCity will offer a **triple-digit APR** through a combination of 3 concepts: **DeFi** [**Nodes**](https://nostracity.gitbook.io/nostracity/assets/nodes)  **+** [**Bonding**](https://nostracity.gitbook.io/nostracity/tokenomics/bonding) **+** [**NFTs**](https://nostracity.gitbook.io/nostracity/assets/nfts)**.** By separating our revenue-generating activities and our payout activities, we will be able to have the most sustainable yields through an **ever-growing treasury**. No tricks or short-term patches, just a solid treasury backing the tokens.

All of it will be gamified through competition of **Mafia Families**: if you vote for an investment and it wins (gets the most votes), you will earn a percentage more with the family (people that voted for the same investment). For more, check out the session [prizes-and-competition](https://nostracity.gitbook.io/nostracity/gamification/prizes-and-competition "mention").

## Why does NostraCity exist?

* To make asymmetric bets that generate outsized gains.
* To be a more fun, sustainable way to invest in both contrarian and growth protocols.
* To fix the issues with well-meaning but concept-broken yield protocols.
