Enzym is a dApp and the ZYM is an ERC20 token. We use the blockchain to bring transparency and security to the user. Enzym is a free mobile game that triggers encounters outside our usual circles (friends, family, colleagues…). Players can receive challenges/missions that will lead to meetings. Every challenge is different. It can be played by two or more people, with strangers or with friends, over a few hours or several days… To play, a user needs ZYMs, the fuel of the application. Some actions will make him win, other will make him lose ZYMs.
