# Staking Mechanics

Stake $PRFI tokens inside your PRFI ONFT to level it up, increase your multiplier, and earn a larger share of the monthly reward pool.

***

## How Staking Works

1. Connect your wallet to the staking platform at [primestaking.xyz](https://primestaking.xyz)
2. Select your PRFI ONFT
3. Enter the amount of $PRFI you want to stake
4. Confirm the transaction

The staked $PRFI is held inside the NFT's smart contract. Your level is computed automatically based on how much $PRFI is staked.

***

## Levels

There are **20 levels**. Each level requires a cumulative total of staked $PRFI and adds **+0.1** to your multiplier.

| Level | Added Multiplier | Total PRFI Staked | PRFI Needed to Level Up |
| ----- | ---------------- | ----------------- | ----------------------- |
| 0     | 0.0              | 0                 | 15                      |

> **PRFI needed to max out an NFT = 41,490.** You can check your current level and the PRFI needed to reach the next level on the NFT detail page on PrimePort.

## Key Contract Functions

The staking logic lives in the verified smart contract on Base. Key functions include:

| Function                      | Description                                              |
| ----------------------------- | -------------------------------------------------------- |
| `getNFTData(tokenId)`         | Returns the staked amount, multiplier, and lock status   |
| `getTokenLevel(tokenId)`      | Returns the current level (computed from staked amount)  |
| `getAmountToLevelUp(tokenId)` | Returns how much more $PRFI is needed for the next level |
| `checkLevel(staked)`          | Given a staked amount, returns the corresponding level   |

> **Note:** The level is not stored on-chain, it is computed dynamically from the staked balance. This means your level updates instantly when you stake more $PRFI.

***

## Locking (soon available)

You can optionally **lock** your PRFI ONFT on PrimeFi for a specified period. Locking is required to be eligible for the **40% PrimeFi profit sharing** rewards. The lock status is visible on the NFT detail page.
