# Items and Unlocks
> Create ERC-721 items for gating, collectibles, and in-app utility.
## Creating Items
Items adhere to the ERC-721 standard, and are created through the InAppContent721 contract. Each item has:
| Property | Description |
| ---------- | ------------------------------------------------------- |
| Name | Display name for the item |
| Price | Cost in app tokens (burned on purchase) |
| Soulbound | Whether the item is transferable or locked to the buyer |
| Max supply | Optional cap on total mints |
***
## Item Types
| Type | Purpose | Example |
| ----------- | ------------------------------------------ | -------------------------------------------- |
| Access Pass | Gate features or content | "Pro Mode" unlock, exclusive dashboard |
| Cosmetic | Visual customization | Profile borders, badges, themes |
| Power-up | Temporary or persistent gameplay advantage | Double XP for 24 hours |
| Collectible | Limited-edition tokens | Launch day commemorative, achievement badges |
***
## Burn Mechanics
All item purchases burn 100% of the app tokens spent. This creates direct deflationary pressure on the app token supply.
When a user buys an item:
1. App tokens are transferred from the buyer
2. Tokens are burned (sent to the zero address)
3. The item is minted to the buyer
There is no treasury cut or fee on item purchases. The entire price is removed from circulation.
***
## Feature Gating
Use items to gate app features. Check ownership in your frontend:
```javascript theme={null}
const hasAccess = await contract.balanceOf(userAddress) > 0;
if (hasAccess) {
// Show premium feature
} else {
// Show purchase prompt
}
```
For soulbound items, `balanceOf` is the only check needed since the item cannot be transferred away.
***
## Soulbound vs Transferable
| Property | Soulbound | Transferable |
| ---------------------------- | --------------------------- | ----------------------- |
| Can be sold or traded | No | Yes |
| Appears on secondary markets | No | Yes |
| Best for | Access passes, achievements | Collectibles, cosmetics |
| Ownership check | Wallet-locked | Can change hands |
Use soulbound items for access gates and feature unlocks. Use transferable items for collectibles and cosmetics that users may want to trade.
