# Staking

LiQ’s staking model is designed to maximize yield for MNT holders by leveraging DeFi strategies. Staked MNT is deployed into these strategies to generate returns. Stakers receive stMNT, a liquid staking token that represents their staked MNT and accrued rewards.

## Key Components

1. Staking Pool:\
   The staking pool is a smart contract where users deposit their MNT tokens. These tokens are then deployed into DeFi strategies to generate yield.
2. stMNT (Staked MNT):\
   Upon staking, users receive stMNT, a liquid staking token that represents their share of the staking pool. stMNT is transferable and can be used in other DeFi protocols while still earning staking rewards.
3. DeFi Strategies:\
   LiQ employs a variety of DeFi strategies to generate yield, including: High performing yield vaults on Mantle and across other chains

      **Yield Farming**: Depositing assets into yield farming protocols to earn additional rewards. 

      **Lending**: Lending MNT to borrowers on lending platforms to earn interest.

4. **Rewards Distribution**:\
   Rewards generated from DeFi strategies are distributed to stakers in the form of additional stMNT. The value of stMNT increases over time as rewards are accrued.

## Staking Process

**Step 1:** Deposit MNT Users deposit their MNT tokens into the LiQ staking pool. This is done through a simple transaction on the Mantle Network.

```solidity
// function stakeMNT(uint256 amount) external {
    require(amount > 0, "Amount must be greater than 0");
    require(MNT.transferFrom(msg.sender, address(this), amount), "Transfer failed");

    uint256 stMNTAmount = amount;
    if (totalStaked > 0) {
        stMNTAmount = (amount * totalStMNT) / totalStaked;
    }

    _mint(msg.sender, stMNTAmount);
    totalStaked += amount;
    totalStMNT += stMNTAmount;

    emit Staked(msg.sender, amount, stMNTAmount);
}
```

**Step 2**: Receive stMNT Upon depositing MNT, users receive stMNT tokens at a 1:1 ratio initially. The value of stMNT increases as rewards are accrued.

**Step 3:** DeFi Strategy Deployment The staked MNT is deployed into various DeFi strategies by the LiQ protocol. These strategies are carefully selected to balance risk and reward.

**Step 4:** Accrue Rewards Rewards generated from DeFi strategies are automatically reinvested into the staking pool, increasing the value of stMNT over time.

```solidity
// function accrueRewards(uint256 rewards) external onlyStrategy {
    uint256 stMNTRewards = (rewards * totalStMNT) / totalStaked;
    totalStMNT += stMNTRewards;
    totalStaked += rewards;

    emit RewardsAccrued(rewards, stMNTRewards);
}
```

**Step 5:** Redeem MNT Users can redeem their stMNT for MNT at any time. The amount of MNT received is proportional to the current value of stMNT, which includes accrued rewards.

```solidity
// function redeemMNT(uint256 stMNTAmount) external {
    require(stMNTAmount > 0, "Amount must be greater than 0");
    require(balanceOf(msg.sender) >= stMNTAmount, "Insufficient stMNT balance");

    uint256 mntAmount = (stMNTAmount * totalStaked) / totalStMNT;
    _burn(msg.sender, stMNTAmount);
    totalStaked -= mntAmount;
    totalStMNT -= stMNTAmount;

    require(MNT.transfer(msg.sender, mntAmount), "Transfer failed");

    emit Redeemed(msg.sender, stMNTAmount, mntAmount);
}
```

## 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://liq-3.gitbook.io/stake.liq/staking-module/staking.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.
