# On-Chain Inventory

## Let Players Own Their Items—Forever

Build blockchain inventories where players truly own their loot. No server wipes, no lost progress. Just permanent, tradeable, cross-game items stored as NFTs.

Used by 47+ games

340% retention boost

£1.2M+ trading volume

## Traditional vs. On-Chain Inventory

### Traditional Inventory

- Server crash = items gone forever
- Game shuts down = years of progress deleted
- Admins can nerf your legendary sword anytime
- Can't trade items outside the game
- Players don't trust you with their £1000 sword

### On-Chain Inventory

- Items stored on blockchain = permanent ownership
- Game servers die? Items live forever on-chain
- Immutable stats = can't be nerfed or changed
- Players trade on OpenSea, your marketplace, anywhere
- 340% retention boost = happier, loyal players

### Legendary Sword

**ERC-721**

### Dragon Scale Armor

**ERC-1155**

### Fire Phoenix

**ERC-721**

### Blockchain Attributes

- damage: 150
- durability: 100
- rarity: Legendary
- owner: 0x742d...5f3a

These attributes are stored on the blockchain and cannot be altered by anyone. True item permanence.

## Why Developers Choose On-Chain Inventory

Build trust, boost retention, and create real player value

### True Ownership

Every item is an NFT on the blockchain. Players own their items—not you, not the server. They can keep them forever.

### Cross-Game Compatible

Items work across multiple games. That sword from Game A? Use it in Game B. Build a shared metaverse economy.

### Tamper-Proof Stats

Item stats are stored on-chain. No server admin can nerf your legendary sword. Stats are permanent and immutable.

### Real-Time Analytics

See which items players love, trade volume, rarity distribution. Data-driven game balancing in real-time.
