# Character Keys

MemeFi is **not** just a Web3 game. It's a **Social Tech app**. That's why we have **social keys**, a feature that enables players to leverage their investor flair to earn rewards from other palyers.

Basically, when a user purchases a key from another player they receive **a cut of $MEMEFI** from their daily rewards payout. In turn, the key issuer (the person whose key is bought) collects key trading **transaction fees** and enjoys **a rise** in their key value.

#### **Reward model**

In MemeFi, new $MEMEFI rewards are only issued in **boss fights**, while the rest of the game economy amounts to **the redistribution** of the said rewards.

A user's rewards for a day of gameplay can be devided into two distinct parts: **the core reward (60%)** and **the surplus reward (40%)**. The surplus is **the extra reward** — it's devided between key holders, equally per each key.

As the play owns at least one of their own keys, they will receive a **certain portion** of their own rewards. If nobody else bought their keys, they will enjoy the full value of their surplus reward. 

With each new purchase, the surplus reward cut per one key is **fragmented** more and more. Players can **preemptively** buy more than one of their own keys to dissuade buyers, pumping the key price and fragmenting its reward share, as it would make the key **a worse deal** based on the expected profit/price ratio.

#### **Key price**

Key prices scale according to a **fixed curve**, which is possible due to a pool model employed. Each new increse in supply drives the value **higher** based on a quadratic bonding curve.

#### **Profit avenues**

For buyers:

* Yield (rewards from key issuers)
* Rise in the key's value

For key issuers:

* Key trading fees
* Rise in the key's value
