# $ALTAR The $ALTAR token acts as the **core** currency within the protocol, available for purchase on Uniswap via $ETH. **Possession** of $ALTAR is **essential** for engaging with the protocol and beginning to accrue rewards. Our token is not a regular ERC20 Token. It is subject to a debase every epoch (**occurring every blocks**). This mechanism results in a **reduction of the circulating supply** for holders of $ALTAR who have not interacted with our protocol. This debase not only emphasizes the importance of active participation and utility but also serves to make $ALTAR **increasingly scarce**, **enhancing** its potential value over time. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
