Contract 5: CrossChainBridge - NFT Portability

struct NFTSnapshot {
    uint256 level;
    uint256 energy;
    uint256 strength;
    uint256 stamina;
    string zone;
    string elementAffinity;
    string lootTier;
    bytes32 snapshotHash;
    uint256 timestamp;
}

What's happening here?

• Creates a "photo" of the NFT's current state

• Captures all important traits at a specific moment

• Hash ensures data integrity during transfer

function createSnapshot(uint256 tokenId) external returns (bytes32) {
    require(evolutionNFT.ownerOf(tokenId) == msg.sender, "Not owner");
    
    // Capture current traits
    NFTSnapshot memory snapshot = NFTSnapshot({
        level: traitFusion.getTraitAsUint(address(evolutionNFT), tokenId, "level"),
        energy: traitFusion.getTraitAsUint(address(evolutionNFT), tokenId, "energy"),
        strength: traitFusion.getTraitAsUint(address(evolutionNFT), tokenId, "strength"),
        // ... other traits
    });
    
    // Create hash of all traits
    bytes32 hash = keccak256(abi.encode(
        snapshot.level,
        snapshot.energy,
        snapshot.strength,
        // ... all traits
    ));

What's happening here?

• Reads all current traits from TraitFusion

• Creates a cryptographic hash of all the data

• This hash proves the data hasn't been tampered with
