Overview

TraitForge Overview - ManPeach

TraitForge is a competitive and collaborative breeding game with a nuke function. Each NFT (Entity), has set Traits, created and calculated before mint, by indexing the entropy slots. Each digit or total entropy, gives the NFT its unqique traits, that are determined but completely dispursed/random. Players can forge (breed), by either listing a forger, or paying a forger and receiving the new NFT. Nuking is a function where players burn their NFT, in return claim a portion of ETH from the nuke-fund, in proportion to the 'nuke factor' of the entity, which increases overtime.

Players compete in every aspect of the game, whether its minting the best NFT's available, trading or listing for forging in a competitive market or nuking when the time is right.

TraitForge: The NFT Honeypot Game

Abstract

TraitForge revolutionizes NFT gaming by integrating strategic, value-driven gameplay around a central honeypot, designed to scale and captivate participants across the NFT ecosystem.

Introduction

TraitForge offers an enduring game experience, transcending the typical NFT model by providing a dynamic, strategic environment focused on a central honeypot, facilitating continuous engagement and value creation.

Core Mechanics

  • Entities: NFTs with unique traits and parameters impacting the game.
  • Generations & Minting: Starting with Gen 1 entities, the game evolves through a breeding mechanism, expanding the ecosystem.
  • Honeypot/Nuke Fund: Central economic feature where players can claim shares by "nuking" their entities.
  • Entropy System: A unique mechanism dictating entity traits and strategic parameters.

Strategic Gameplay

Involves managing entities through aging, forging, and strategic decisions impacting the honeypot's dynamics and player's potential gains.

Development and Community

Built with Next.js, Hardhat, and Wagmi/Viem.

TraitForge is not just a game; it's an evolving NFT ecosystem designed for strategic depth, community involvement, and sustainable value growth.

N/A

Additional context

Main invariants

Most things won’t change aside from settable variables (eg: max generations)

Attack ideas (where to focus for bugs)

  • Possibly re-entry to NukeFund
  • Inefficient/fragile mappings (especially with tokens and listings)

All trusted roles in the protocol

Role Description
Contract Owner

Describe any novel or unique curve logic or mathematical models implemented in the contracts

Bit stuffing for entropy generator. 770 UINT256’s, each UINT = 78 digits /13 = 13 x 6 digit entropies
