Every time you stake BNB with a vesting duration **greater than 0 hours**, you receive a **Key NFT** — a powerful, tradable token-bound NFT that represents your stake, vesting time, and upcoming KeyFi tokens reward.

***

## What’s Inside a Key NFT?

Each Key NFT (ERC-721 standard) contains:

* **Total KeyFi Token Amount** (base + bonus)
* **Remaining Vesting Time**
* **Claimable Status** once vesting ends
* **Tradability** — can be sold on the NFT Marketplace anytime

***

## Use Cases

* **Hold Until Vesting Ends:**\
  After the timer expires, convert the NFT into KeyFi tokens and claim them to your wallet.
* **Sell Anytime Before Vesting Ends:**\
  List your Key NFT on the **Marketplace** — a buyer can acquire your future yield early. Great for early exits or flipping strategies.
* **Buy Discounted Keys from Others:**\
  Traders can sweep the marketplace, buying Keys with remaining bonus yields at potentially discounted prices.

## Lifecycle of a Key NFT

1. You stake BNB → System swaps to KeyFi tokens via AMM
2. You receive a Key NFT (if vesting > 0h)
3. NFT contains all KeyFi tokens + bonus info
4. You can **hold**, **sell**, or **wait to claim**
5. Once vesting ends → **burn NFT** to claim KeyFi tokens
