# Staking technical design

### Overview

Kanpai NFT Staking allows users to earn rewards based on their NFTs without requiring the application to take custody of their assets. This soft staking mechanism operates off-chain, so users retain full control of their NFTs within their wallets. The system supports multiple chains, including Solana and EVM-compatible chains, and monitors ownership and transfers across all supported chains.

***

### Supported Collections

The staking platform supports the following collections:

* Kanpai Pandas
* Infinity Pandas

These collections are eligible for staking across all supported chains.

**Note:** Honoraries are not eligible.

### Staking Mechanics

#### 1. Daily STRIKE Earnings

Rewards are calculated using the simplified formula:

```
dailyStrike = nftDailyEarning × 0.20832063
```

* `nftDailyEarning` is a value embedded in the NFT metadata and reflects rarity.
* The multiplier `0.20832063` is based on the amount of STRIKE allocated for staking, proportioned to the original Panda Point reward system.

#### 2. Score and Rewards Updates

* Rewards accumulate daily and are tracked per NFT.
* Each NFT’s staking streak (consecutive days staked) contributes to monthly bonus calculations.
* The system updates daily to reflect new earnings.

#### 3. Ownership Transfers

If an NFT is transferred, even between a user’s own wallets:

* The staking streak and score reset to 0.
* This applies across all supported chains.

#### 4. Unstaking

* Unstaking pauses staking streak and reward accumulation.
* Existing rewards remain claimable.
* If an NFT is transferred while unstaked, streak and eligibility reset.

#### 5. Listing NFTs

* Listed NFTs are treated as unstaked.
* All progress is reset.

***

### Authentication

Users must authenticate via wallet connection and message signing:

* **SIWE (Sign-In with Ethereum)** for EVM chains.
* **SIWS (Sign-In with Solana)** for Solana chains.

This ensures wallet integrity and links staking progress to user profiles.

***

### Cross-Chain Monitoring

The app continuously tracks NFT ownership across Solana and EVM chains:

* Real-time updates detect any transfer events.
* Transfers reset staking streaks and scores.

***

### Key Notes

* **Daily rewards** reflect NFT rarity and staking activity.
* **Ownership transfers** reset staking streaks — even self-transfers.
* **Unstaking pauses**, but transferring while unstaked resets everything.
* **Listed NFTs** are ineligible.
* **Soft staking** means NFTs never leave the user’s wallet.
