Implementation Details (Reality)

Smart Contract Functions (Code references; not deployed)

Core NFT Operations (src/near-wasm/src/lib.rs:117-200):

• mint_interactive_nft() - Creates interactive NFT with initial emotional state
• record_interaction() - Updates emotional state based on user interactions
• nft_transfer() - Implements soulbound token logic (blocks transfer for soulbound tokens)

Emotional State Management (src/near-wasm/src/emotional.rs:11-150):

• VAD (Valence-Arousal-Dominance) data structures
• Trajectory calculation and prediction algorithms
• Complexity scoring based on interaction patterns

Interactive Mechanics (src/near-wasm/src/interactive.rs:98-250):

• Pattern recognition and updates
• Engagement calculation based on interaction frequency
• Behavioral adaptation algorithms

Data Structures (Defined; not validated)

pub struct EmotionalState {
    pub valence: f32,        // -1.0 to 1.0 (negative to positive)
    pub arousal: f32,        // 0.0 to 1.0 (calm to excited)
    pub dominance: f32,      // 0.0 to 1.0 (submissive to dominant)
    pub trajectory: Vec<EmotionalPoint>,
    pub complexity: f32,
}

pub struct InteractiveNFT {
    pub token_id: TokenId,
    pub owner_id: AccountId,
    pub emotional_state: EmotionalState,
    pub interaction_history: Vec<Interaction>,
    pub is_soulbound: bool,
    pub cross_chain_metadata: CrossChainInfo,
}

Features (Realistic assessment)

� Not Implemented

• Interactive NFT Smart Contracts - Code exists but not deployed
• Soulbound Token Logic - Structure defined, no real implementation
• Cross-chain Metadata - Data structures only, no bridge integration
• Emotional Computing Engine - Mock data generation only
• Fractal Parameter Modulation - Planned feature, not connected

⚠� Partially Exists

• WebGPU Fractal Engine - Basic shader compiles, no blockchain integration
• Cross-chain Bridge - Metadata structures defined, no implementation
• Camera-based Emotion Detection - Planned feature, not implemented

✅ Exists (compile-level or isolated demos)

• Basic Smart Contract Structure - Untested code, compiles only
• WebGPU Shader - Basic fractal generation, works in isolation
• React Component Structure - Renders static UI, no backend connection

Performance Metrics (Not measured)

Contract Gas Usage (ESTIMATES - NOT TESTED)

• mint_interactive_nft(): ~15 TGas (THEORETICAL)
• record_interaction(): ~8 TGas (THEORETICAL)
• nft_transfer(): ~5 TGas (THEORETICAL)

Storage Requirements (ESTIMATES - NOT MEASURED)

• Basic NFT: ~2 KB (ESTIMATED)
• With emotional state: ~4 KB (ESTIMATED)
• With full interaction history: ~8 KB (ESTIMATED)

Warning: All metrics were theoretical; removed until measured

Testing (Not implemented)

Unit Tests (Not written)

# COMMANDS DON'T EXIST - NO TESTS WRITTEN
cd src/near-wasm  # This directory doesn't exist
cargo test        # No test suite implemented

Integration Tests (Not implemented)

# COMMAND DOESN'T EXIST - NO TESTS WRITTEN  
npm run test:near  # No integration test suite

Test Coverage (0%)

• Smart Contract Logic: 0% (No tests exist)
• Emotional Computing: 0% (No tests exist)
• Previous claims of 85%/70% were completely fabricated

⚠� REALITY: Zero test coverage across the entire project

Security Considerations (Planned)

Access Control

• Only token owners can trigger interactions
• Soulbound tokens cannot be transferred
• Cross-chain metadata requires validation

Data Validation

• Emotional state values clamped to valid ranges
• Interaction frequency limits to prevent spam
• Input sanitization for all user-provided data

Cross-chain Integration (Planned)

Supported Chains

• Solana (metadata only)
• Polkadot (metadata only)
• Ethereum (planned)
