Fragment Protocol

A novel blockchain ownership primitive that transforms traditional NFT mechanics through fragment-based architecture. NFTs are composed of exactly 4 collectible fragments that users must acquire, complete, and transform through a systematic burn-to-fuse workflow.

Overview

Fragment Protocol introduces fragment-based multi-ownership where complete NFTs require collecting 4 separate fragment tokens. This creates a collection → completion → transformation lifecycle with unprecedented interface complexity requiring specialized UI patterns.

Core Workflow: Mint random fragments → Collect complete sets → Burn fragments → Fuse into transformation NFTs

Architecture

Multi-Contract System:

• FragmentEngine: Fragment minting, ownership verification, and burning operations
• FragmentFusion: Burn-to-fuse transformation with access control and fusion NFT creation
• FragmentRandomness: Development-grade randomness for fair fragment distribution

Key Features:

• Fragment sets with dynamic completion states (0/4, 1/4, 2/4, 3/4, 4/4)
• Irreversible burn operations unlocking transformation potential
• Cross-contract workflow coordination for multi-step processes
• Comprehensive testing suite with 80+ validation scenarios

UI Research Context

Fragment Protocol serves as the technical foundation for researching interface requirements for experimental ownership primitives.

Research Focus: What UI patterns are essential for fragment collection progress, completion validation, and transformation workflows?

Grant Objective: Produce prototype interface components and builder experimentation guidelines for novel NFT (Fragment-Based Multi-Ownership) mechanics.
