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. Nexus Nemesis: The Game

Nexus Nemesis is a TCG that emphasizes skill, strategy, and community.

3.1. Gameplay Overview

Tribes: The game features various tribes, influencing card synergies and strategies (e.g., Iron Will, Tribal War, Fabled, Blood For Conquest, Ethereal Signature).
Card Elements: Cards have attack (⚡) and health (❤️) stats, along with mana costs.
Unique Traits & Abilities: Cards can possess rare traits like "Life" (+1 Health), "Fire" (+1 Attack), "Foil" (cosmetic), and abilities such as "Haste," "Ally Boost," or "Stealth."
Hero Cards: Special, powerful cards that can be minted.
Ethereal Signature Cards: Mythic rarity cards with enhanced stats and unique field/deck limitations.

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, which emit CardMinted events for transparency.
Pack Types:
- Starter Pack: 5 cards (10 GBUX)
- Premium Pack: 10 cards (50 GBUX), with enhanced probabilities for rarer cards and traits.
- Legendary Pack: 3 cards (100 GBUX), with high-value probabilities.
Total Mint Limit for Season 0: 100,000 cards, enforced by the smart contract to ensure scarcity and value.

3.3. In-Game Economy: GBuX and GRUDA

GBuX: The primary in-game currency for Nexus Nemesis, used for purchasing card packs and other in-game items.
GRUDA Integration:
- Players can earn GRUDA through gameplay achievements, tournament victories, and other merit-based contributions within the Nexus Nemesis ecosystem.
- GRUDA can be swapped for GBuX at a defined ratio (e.g., 1 GRUDA : 100 GBuX). This creates a direct link between performance in Nexus Nemesis and the broader GRUDA network value.

4. Nexus Nemesis & The GRUDA Ecosystem

Nexus Nemesis is more than just a game; it's a showcase for the GRUDA protocol and a model for future projects.

Proof of Play in Action: Gameplay achievements in Nexus Nemesis directly contribute to a player's Merit Score on the GRUDA network, influencing their GRUDA earnings. This rewards skill and engagement.
Community Building: By rewarding contributions like content creation, tournament organization, and community moderation, Nexus Nemesis fosters a strong, self-sustaining community, aligning with GRUDA's social engagement principles.
Economic Symbiosis: The GBuX ↔ GRUDA swap mechanism ensures that the in-game economy of Nexus Nemesis is intrinsically linked to the health and growth of the GRUDA network.
A Blueprint for Future Projects: Grudge Studio, through Nexus Nemesis, provides a clear example of how other gaming communities and developers can:
- Integrate their games with the GRUDA network.
- Leverage the merit-based reward system.
- Utilize the cross-chain bridge for broader reach.
- Apply for grants from the GRUDA Ecosystem/Development Fund.

5. Technical Architecture

NFT Standards: Nexus Nemesis cards are minted as ERC721 NFTs on the Polygon network using the NexusNemesisCards smart contract, ensuring compatibility with GRUDA's architecture.
Solana/Polygon Bridge: The GRUDA bridge will allow for potential future interoperability of Nexus Nemesis assets or related tokens on the Solana network.
Merit Verification: Nexus Nemesis integrates with GRUDA's merit verification system to validate gameplay achievements and other contributions.

5.1. NexusNemesisCards Smart Contract

The NexusNemesisCards smart contract, deployed on Polygon, governs the minting and management of Nexus Nemesis cards as ERC721 NFTs. Key features include:

Season 0 Minting Limit: Enforces a cap of 100,000 cards, tracked via the season0MintedCount variable, ensuring scarcity.
On-Chain Metadata: Each card's attributes (e.g., name, tribe, rarity, attack, health, abilities) are stored in a CardData struct, accessible via the getCardData function.
Tribe and Rarity Tracking: Maintains counts of cards by tribe (e.g., Ethereal, Iron Will) and rarity (e.g., common, legendary) using mappings, with statistics retrievable via getSeason0Stats.
Minting Functions: Supports single card minting (mintSeason0Card) and batch minting (batchMintSeason0Cards), restricted to the contract owner for controlled distribution.
Event Logging: Emits CardMinted events for each minted card, recording the token ID, owner, tribe, rarity, and serial number for transparency.
Integration with GRUDA: The contract aligns with GRUDA's ecosystem by enabling cards to be used in merit-based activities, with potential future bridging to Solana for wGRUDA compatibility.

This contract ensures that Nexus Nemesis cards are secure, verifiable, and interoperable within the GRUDA ecosystem, providing players with true ownership and traceability.
