Blockchain Layer

While there are over 40 smart contracts that make up the system, here are the four primary ones that contribute to the base game operation.

Game Engine

Main System Controller

This is the blockchain “brain” for a game. For example, in CropXYZ, all the requests that users make, in one way or another, goes through this set of smart contracts.

Economic Engine

Complete automated market maker

This is a UniSwap-inspired constant product, automated market maker that hosts 24 different liquidity pools for CropXYZ. This is extensible enough to support any ERC20 token in relation to the internal currency (“zGOLD”).

Address Store

Contract Address:
