Nexus Nemesis: A New Era of Trading Card Games on the GRUDA Network
Grudge Studio | May 2025

Abstract
Nexus Nemesis is a cutting-edge Trading Card Game (TCG) developed by Grudge Studio, representing the flagship application of the GRUDA network. This white paper outlines the vision, gameplay mechanics, tokenomics, and roadmap of Nexus Nemesis, emphasizing its role in showcasing the GRUDA ecosystem's capabilities. GRUDA, a Layer 1 cryptocurrency built on Polygon with cross-chain functionality to Solana, introduces a merit-based token generation system. Nexus Nemesis is the first project to leverage GRUDA, demonstrating how gaming communities can build, own, and thrive within this innovative framework.

1. Introduction: The Grudge Studio Vision
Grudge Studio was born from a passion for the social and strategic depths of TCGs like Magic: The Gathering, Yu-Gi-Oh!, and Hearthstone. We believe TCGs are more than just games; they are creators of moments, connections, and memories. In the Web3 era, we see an opportunity to elevate this experience by integrating true asset ownership, creator rewards, and community-driven governance. Our philosophy is "build first, play later," and Nexus Nemesis is the culmination of this approach – a fully realized platform ready for players.

2. GRUDA: The Foundation for Merit-Based Gaming
GRUDA is a revolutionary Layer 1 blockchain designed to transform value generation and distribution in gaming and social ecosystems.

Key Features of GRUDA
Merit-Based Token Generation: Unlike traditional cryptocurrencies, new GRUDA coins are minted only through verifiable contributions to the ecosystem. This is calculated using a Merit Score:
Merit Score = α(Game) + β(Social) + γ(Ecosystem)
Token Reward = Base Reward × Merit Score × Time Factor
Hybrid Consensus Mechanism: GRUDA combines Proof of Stake (PoS), Proof of Work (PoW), and the innovative Proof of Play (PoP) to ensure security, engagement, and sustainability.
Cross-Chain Capabilities: A secure bridge between Polygon (main ERC-20 contract) and Solana (wGRUDA SPL token) facilitates seamless asset transfers and interoperability.
Gaming Integration: Designed for seamless implementation with games like Nexus Nemesis.
Community-Centric Tokenomics:
30% - Validators/Miners
20% - Ecosystem/Development Fund
15% - Grants Program
25% - Community Treasury
10% - Founding Team (3-year vesting)
Nexus Nemesis serves as the prime example of how projects can be built on GRUDA, leveraging its unique features to foster a vibrant and rewarding ecosystem. It demonstrates the pathway for other communities to launch their projects on the GRUDA network.

3.2. Season 0: The Genesis
Nexus Nemesis will launch with "Season 0," introducing the initial set of cards and mechanics.

Minting Process: Players acquire cards by minting them as NFTs via the NexusNemesisCards smart contract on Polygon. Each card is an ERC721 token with a unique serial number and on-chain metadata, ensuring authenticity and ownership. The contract enforces a strict limit of 100,000 cards for Season 0, with attributes like tribe, rarity, attack, health, and abilities stored in a CardData struct. Minting is controlled by the contract owner (Grudge Studio) using functions like mintSeason0Card and batchMintSeason0Cards, whic
