# Piggybank

> ### <mark style="color:purple;">The piggybank concept</mark>

In order to ensure a floor price for each ZAI, the ZAI has a piggybank that will be credited with 5% of the reward (BZAI) collected in combat.

The piggybank is inaccessible to the owner of the ZAI. \
The only way to get the piggybank amount is to burn the ZAI to the Gods.
