# User Overview

**PRFI NFTs — Staking & Rewards**

PRFI NFTs let you earn a share of a monthly PRFI reward pool by staking PRFI tokens inside collectible NFTs. The more you stake and the rarer your NFT, the larger your share.

***

**How It Works**

1. **Get a PRFI NFT** — available on OpenSea (Base network)
2. **Stake PRFI into your NFT** — your NFT gains levels as your stake grows
3. **Earn monthly rewards** — your share is determined by your NFT's rarity and staked amount
4. **Claim anytime** — rewards are claimable on any supported chain
5. **Grow your position** — merge two same-rarity NFTs into a higher rarity for stronger multipliers

***

**Reward Pool**

100,000 PRFI distributed monthly across all staked NFTs.

Your share depends on two equal factors:

* **Rarity multiplier** — determined by your NFT's rarity tier (Common → Legendary)
* **Stake weight** — your staked PRFI × your rarity multiplier

This means both the quality of your NFT and the size of your stake matter. A high-rarity NFT with low stake and a low-rarity NFT with high stake can earn similar rewards.

***

**NFT Levels & Rarity**

Staking PRFI increases your NFT's level (up to level 20). Higher levels increase your reward weight.

Merging two NFTs of the same rarity produces a single NFT with higher rarity and a stronger multiplier. The merged NFTs are burned and a new NFT is minted — your combined stake carries over.

***

**Withdrawing PRFI**

There are three withdrawal paths:

**Fee-free surplus withdrawal** — if your staked PRFI exceeds 41,490 PRFI (the maximum level threshold), you can withdraw the surplus above that amount at 0% fee using the "Get Surplus" function. Your NFT level remains unchanged.

**Below-threshold withdrawal** — if you withdraw PRFI that reduces your stake below 41,490 PRFI, a 20% fee applies to the withdrawn amount. This fee is redistributed proportionally to all other stakers. To avoid this fee, use the surplus function first to reduce your position above the threshold before withdrawing further.

**Burn to redeem** — destroy your NFT to withdraw all staked PRFI instantly. No fee applies, but the NFT is permanently burned.

***

**Where to Get PRFI NFTs**

PRFI NFTs live on the Base network (Ethereum L2) and are tradeable on OpenSea.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.primefi.xyz/rewards-and-tokens/prfi-staking-nfts/prime-numbers-staking-design/user-overview.md?ask=<question>&goal=<endgoal>
```

`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.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
