How Cross-Game Works

Universal NFT Standards

Standardized Metadata Structure

Core Principles:

  1. Persistent Identity: NFT remains the same across games
  2. Adaptive Stats: Base stats translate to game mechanics
  3. Shared Progression: XP earned anywhere counts everywhere
  4. Visual Consistency: Art style adapts but character preserved

Game Integration Examples

  • Special: Unique skill trees
  • Progression: Quest completion = XP

4. Strategy Game

Technical Architecture

Cross-Game SDK

Developer Integration

import { ProjectJSDK } from '@projectj/sdk';

class GameIntegration {
private sdk: ProjectJSDK;

async loadPlayerNFTs(walletAddress: string) {
// Fetch all NFTs owned by player
const nfts = await this.sdk.getNFTs(walletAddress);

// Convert to game-specific format
return nfts.map(nft => this.adaptNFTToGame(nft));
}

adaptNFTToGame(nft: NFTCard): GameCharacter {
return {
id: nft.id,
name: nft.name,
// Translate base stats to game mechanics
health: nft.base_stats.health * this.HEALTH_MULTIPLIER,
damage: nft.base_stats.attack * this.DAMAGE_MULTIPLIER,
// Preserve rarity advantages
rarityBonus: this.getRarityMultiplier(nft.rarity),
// Convert abilities
skills: this.translateAbilities(nft.abilities)
};
}

async syncExperience(nftId: string, xpGained: number) {
// Update XP on blockchain
await this.sdk.addExperience(nftId, xpGained);
}
}

Key Features:

  • Plug-and-play integration
  • Automatic stat translation
  • Real-time sync
  • Minimal development effort
