# General

Game uses ERC-20 tokens:

* Governance DAO token $MYRD
* In-game token $SACRA

The $MYRD token is central to facilitating governance actions within the ecosystem, enabling holders to mint $SACRA at a one-to-one ratio and earn passive income. This mechanism is comprehensively detailed in the corresponding section.

$SACRA  token is used for all internal actions, which is represented in the Utility section.

To start the game, users should buy a hero NFT for a certain amount of $SACRA. Also users need to level up their heroes to get relevant rewards, which also costs a certain amount of $SACRA. Every hero is an accumulation of $SACRA.
