# Staked $WATT NFTs
Staked $WATT tokens will be represented by a non-fungible receipt token, or NFT, which is automatically minted and added to your wallet upon stake creation.
The NFTs determine the amount of $WATT that has been staked, as well as the total amount of AMP allocated.
The NFT that represents your stake allows for the transfer of the stake to another wallet address. You can sell staked $WATT NFTs on the PixelPark NFT Marketplace without requiring you to unstake and sell the $WATT Tokens.
Owners of staked $WATT NFTs have the ability to claim rewards, unstake, merge stakes, and maintain full ownership through a receipt NFT.
### NFT Tiers and Rarity
Staked $WATT NFT will showcase a unique image determined by the quantity of $WATT and the total AMP share. The WATT tier will define the major theme of the image and the badge at the bottom right while the AMP tier will determine which image in the theme is used. A ranking page showing the different images and badges will be built in the future to show off the tiers.
There are 12 distinct NFT Metadata tiers defined by the amount of staked $WATT and another 12 unique tiers determined by the stake's AMPs. This increases the rarity of the staked $WATT NFT.
WATT Tiers
| Tier | Minimum | Maximum |
|---|
| 1 | 0 | < 10 |
| 2 | 10 | < 100 |
| 3 | 100 | < 1,000 |
| 4 | 1,000 | < 10,000 |
| 5 | 10,000 | < 50,000 |
| 6 | 50,000 | < 100,000 |
| 7 | 100,000 | < 250,000 |
| 8 | 250,000 | < 1,000,000 |
| 9 | 1,000,000 | < 5,000,000 |
| 10 | 5,000,000 | < 50,000,000 |
| 11 | 50,000,000 | < 500,000,000 |
| 12 | 500,000,000 | < 2,800,000,000 |
AMP Tiers
| Tier | Minimum | Maximum |
|---|
| 1 | 0 | < 1 |
| 2 | 1 | < 5 |
| 3 | 5 | < 10 |
| 4 | 10 | < 50 |
| 5 | 50 | < 100 |
| 6 | 100 | < 250 |
| 7 | 250 | < 500 |
| 8 | 500 | < 1,000 |
| 9 | 1,000 | < 2,500 |
| 10 | 2,500 | < 5,000 |
| 11 | 5,000 | < 10,000 |
| 12 | 10,000 | 99,999 |
### Merge Stakes
By merging staked $WATT NFTs, it is possible to create a larger NFT and potentially increase the tier for the total amount of $WATT and AMPs staked.
For example: By merging an NFT that contains 10 $WATT with 9 AMPs with another NFT that contains 100 $WATT and 75 AMPs, the resulting single NFT would have a balance of 110 $WATT and 84 AMPs.
Consolidating your stakes by merging NFTs could potentially enable you to achieve a higher tier image or badge.
### Add to Stake
It is possible to add more $WATT to an existing stake without having to first unstake. The resulting AMPs for the addition will be calculated based on the current WATT/AMP ratio and not the ratio used during the initial stake creation.

```
GET https://docs.powercity.io/core/staking-usdwatt/staked-usdwatt-nfts.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
