Developing Play-to-Earn Games in Solidity

Solution: Part 1

Explore how to structure a Play-to-Earn Treasure Hunt game by separating VRF-based randomness logic from non-random components using Solidity inheritance. Understand token gating, modifiers, and building secure game and payment functions within Ethereum smart contracts.

We'll cover the following...

Inheritance structure

For clarity and code maintainability, we'll separate VRF-related code from the parts of our game that don't depend on randomness.

  • TreasureHuntNoVRF.sol is a base contract containing state variables and modifiers that don't depend on the VRF.

  • TreasureHuntVRF.sol will inherit from TreasureHuntNoVRF.sol and contain all VRF-related inheritance, state variables, and an override implementation of the VRF fullfillRandomWords() function. However, it will not implement the constructor inherited from the VRF contracts; we'll save its ...
