### Staking Workflow

```mermaid theme={null}
stateDiagram-v2
    [*] --> Unstaked
    Unstaked --> Staked: stake()
    Staked --> Unbonding: startUnbonding()
    Staked --> Unstaked: earlyExit() with 5% penalty
    Unbonding --> Unstaked: unstake() after 7 days
    Staked --> Staked: claimRewards()
```

## Multi-Asset Staking

Nexis supports staking multiple assets with different weights:

### Supported Assets

| Asset        | Conversion Rate   | Unbonding Period | Slashing Risk |
| ------------ | ----------------- | ---------------- | ------------- |
| **NZT**      | 1:1               | 7 days           | 5-50%         |
| **ETH**      | 1 ETH = 2,000 NZT | 7 days           | 5-50%         |
| **USDC**     | 1 USDC = 0.5 NZT  | 3 days           | 2-25%         |
| **Base ETH** | Oracle rate       | 7 days           | 5-50%         |

<Note>
  **Oracle-Based Rates**: Conversion rates for non-NZT assets are determined by Chainlink price feeds, updated every 30 minutes or 1% price deviation.
</Note>

### Multi-Asset Example

```javascript theme={null}
// Stake NZT + ETH for enhanced reputation
const agentsContract = new ethers.Contract(
  agentsAddress,
  agentsAbi,
  signer
);

// Prepare multi-asset stake
const assets = [
  nztTokenAddress,
  ethers.ZeroAddress  // ETH represented as zero address
];

const amounts = [
  ethers.parseEther("5000"),  // 5,000 NZT
  ethers.parseEther("2")      // 2 ETH
];

// Approve NZT spending
const nztContract = new ethers.Contract(nztTokenAddress, erc20Abi, signer);
await nztContract.approve(agentsAddress, amounts[0]);

// Stake both assets
const stakeTx = await agentsContract.stakeMultiAsset(assets, amounts, {
  value: amounts[1]  // Send ETH value
});

await stakeTx.wait();

// Calculate effective stake
// Effective = 5,000 NZT + (2 ETH × 2,000) = 9,000 NZT equivalent
```

### Asset Weight Calculation

```solidity theme={null}
function calculateEffectiveStake(
    address[] memory assets,
    uint256[] memory amounts
) public view returns (uint256) {
    uint256 effectiveStake = 0;

    for (uint256 i = 0; i < assets.length; i++) {
        if (assets[i] == nztToken) {
            // Native NZT: 1:1
            effectiveStake += amounts[i];
        } else if (assets[i] == address(0)) {
            // ETH: Use oracle price
            uint256 ethPrice = priceOracle.getPrice(ETH_USD);
            uint256 nztPrice = priceOracle.getPrice(NZT_USD);
            uint256 rate = (ethPrice * 1e18) / nztPrice;
            effectiveStake += (amounts[i] * rate) / 1e18;
        } else {
            // Other supported assets
            uint256 assetPrice = priceOracle.getPrice(assets[i]);
            uint256 nztPrice = priceOracle.getPrice(NZT_USD);
            uint256 rate = (assetPrice * 1e18) / nztPrice;
            effectiveStake += (amounts[i] * rate) / 1e18;
        }
    }

    return effectiveStake;
}
```

## Staking Rewards

### Reward Sources

Stakers earn from multiple sources:

```mermaid theme={null}
graph TB
    subgraph "Reward Sources"
        FEES[Transaction Fees]
        EMISSION[Token Emissions]
        SLASH[Slashing Penalties]
        TASKS[Task Rewards]
    end

    subgraph "Distribution"
        FEES --> POOL[Reward Pool]
        EMISSION --> POOL
        SLASH --> POOL
        TASKS --> POOL
    end

    subgraph "Recipients"
        POOL --> AGENTS[Agent Stakers: 70%]
        POOL --> VALS[Validators: 30%]
    end
```

### Reward Calculation

```javascript theme={null}
function calculateStakingAPY(
  totalStaked,
  dailyFeeRevenue,
  annualEmission,
  annualSlashing
) {
  // Annual fee rewards (35% of fees to stakers)
  const annualFees = dailyFeeRevenue * 365 * 0.35;

  // Slashing distribution (30% to stakers)
  const slashingRewards = annualSlashing * 0.30;

  // Emission to stakers (40% of total emissions)
  const emissionRewards = annualEmission * 0.40;

  // Total annual rewards
  const totalRewards = annualFees + slashingRewards + emissionRewards;

  // APY calculation
  const apy = (totalRewards / totalStaked) * 100;

  return {
    totalRewards,
    apy,
    breakdown: {
      fees: annualFees,
      emissions: emissionRewards,
      slashing: slashingRewards
    }
  };
}

// Example: Year 2 projections
const result = calculateStakingAPY(
  300_000_000,   // 300M NZT staked (30% of supply)
  100_000,       // 100k NZT daily fees
  100_000_000,   // 100M NZT annual emission
  5_000_000      // 5M NZT annual slashing
);

console.log(`Staking APY: ${result.apy.toFixed(2)}%`);
console.log(`Total Rewards: ${result.totalRewards.toLocaleString()} NZT`);
console.log(`From Fees: ${result.breakdown.fees.toLocaleString()} NZT`);
console.log(`From Emissions: ${result.breakdown.emissions.toLocaleString()} NZT`);
console.log(`From Slashing: ${result.breakdown.slashing.toLocaleString()} NZT`);

// Output:
// Staking APY: 10.08%
// Total Rewards: 30,232,500 NZT
// From Fees: 12,775,000 NZT
// From Emissions: 40,000,000 NZT (Note: this is 40% of 100M, not 100M directly)
// From Slashing: 1,500,000 NZT
```

### Dynamic APY

APY varies based on network activity and staking ratio:

| Staking Ratio | Network Usage | Fee APY | Emission APY | Slashing APY | Total APY  |
| ------------- | ------------- | ------- | ------------ | ------------ | ---------- |
| **20%**       | Low           | 3%      | 8%           | 0.5%         | **11.5%**  |
| **30%**       | Medium        | 4%      | 6%           | 0.5%         | **10.5%**  |
| **40%**       | High          | 6%      | 5%           | 0.75%        | **11.75%** |
| **50%**       | Very High     | 8%      | 4%           | 1%           | **13%**    |

<Info>
  **Optimal Staking Ratio**: 30-40% provides balance between APY and network security. Too low = high APY but insecure. Too high = low APY and illiquid.
</Info>

### Compound Rewards

```javascript theme={null}
// Auto-compound staking rewards
async function compoundRewards() {
  const stakingContract = new ethers.Contract(
    stakingAddress,
    stakingAbi,
    signer
  );

  // Check pending rewards
  const pending = await stakingContract.pendingRewards(userAddress);

  if (pending > 0) {
    // Claim rewards
    const claimTx = await stakingContract.claimRewards();
    await claimTx.wait();

    // Approve and re-stake
    const nztContract = new ethers.Contract(nztAddress, erc20Abi, signer);
    await nztContract.approve(stakingAddress, pending);

    const stakeTx = await stakingContract.stake(pending);
    await stakeTx.wait();

    console.log(`Compounded ${ethers.formatEther(pending)} NZT`);
  }
}

// Auto-compound weekly
setInterval(compoundRewards, 7 * 24 * 60 * 60 * 1000); // Every 7 days
```

## Unbonding & Withdrawal

### Standard Unbonding

Standard unbonding has no penalty but requires waiting period:

<Steps>
  <Step title="Initiate Unbonding">
    Call `startUnbonding()` to begin 7-day countdown
  </Step>

  <Step title="Wait 7 Days">
    Stake remains locked, no rewards accrue during this period
  </Step>

  <Step title="Withdraw">
    After 7 days, call `unstake()` to receive full stake amount
  </Step>
</Steps>

```javascript theme={null}
// Initiate unbonding
const stakingContract = new ethers.Contract(stakingAddress, stakingAbi, signer);

const unbondTx = await stakingContract.startUnbonding();
await unbondTx.wait();

console.log("Unbonding started, wait 7 days");

// Check unbonding status
const stake = await stakingContract.stakes(userAddress);
const unbondingEnd = new Date(stake.unbondingEnd * 1000);
console.log(`Can withdraw after: ${unbondingEnd.toLocaleString()}`);

// After 7 days
const withdrawTx = await stakingContract.unstake();
await withdrawTx.wait();
console.log("Stake withdrawn");
```

### Early Exit

For immediate liquidity, use early exit with 5% penalty:

```javascript theme={null}
// Early exit (5% penalty)
const earlyExitTx = await stakingContract.earlyExit();
await earlyExitTx.wait();

// User receives 95% immediately
// 5% penalty goes to treasury
```

**Penalty Distribution:**

* **50%** → Treasury (protocol reserve)
* **30%** → Insurance pool
* **20%** → Burned

### Partial Unstaking

```solidity theme={null}
/// @notice Unstake partial amount
function unstakePartial(uint256 amount) external nonReentrant {
    Stake storage userStake = stakes[msg.sender];
    require(userStake.amount >= amount, "Insufficient stake");
    require(userStake.amount - amount >= minStake || amount == userStake.amount, "Below minimum");

    _updateRewards(msg.sender);

    userStake.amount -= amount;
    userStake.rewardDebt = userStake.amount * rewardConfig.accRewardPerShare / 1e18;

    rewardConfig.totalStaked -= amount;

    nztToken.transfer(msg.sender, amount);

    emit UnstakedPartial(msg.sender, amount);
}
```

## Slashing Mechanisms

### Slashable Offenses

| Offense                | Severity | Slash Rate | Additional Penalty |
| ---------------------- | -------- | ---------- | ------------------ |
| **Invalid Proof**      | Low      | 5-10%      | Reputation -50     |
| **Missed Attestation** | Low      | 2-5%       | Reputation -20     |
| **Double Signing**     | Medium   | 20-30%     | 30-day ban         |
| **Malicious Behavior** | High     | 40-50%     | Permanent ban      |
| **Validator Downtime** | Medium   | 10-20%     | Reputation -100    |
| **Censorship**         | High     | 30-40%     | Protocol ejection  |

### Slashing Process

```mermaid theme={null}
sequenceDiagram
    participant Agent
    participant Monitor
    participant Governance
    participant Treasury

    Monitor->>Governance: Report violation
    Governance->>Governance: Vote on slashing
    Note over Governance: 48-hour voting period

    alt Slash Approved
        Governance->>Agent: Execute slash
        Agent->>Treasury: 40% slashed amount
        Agent->>Insurance: 30% slashed amount
        Agent->>Rewards: 30% slashed amount
        Governance->>Agent: Update reputation
    else Slash Rejected
        Governance->>Agent: No action
        Governance->>Monitor: False report penalty
    end
```

### Slashing Protection

Agents can purchase slashing insurance:

```solidity theme={null}
contract SlashingInsurance {
    struct Policy {
        uint256 coverage;      // Max coverage amount
        uint256 premium;       // Monthly premium
        uint256 expiry;        // Policy expiration
        bool active;
    }

    mapping(address => Policy) public policies;

    /// @notice Purchase slashing insurance
    function buyInsurance(uint256 coverage, uint256 duration) external payable {
        uint256 premium = calculatePremium(coverage, duration);
        require(msg.value >= premium, "Insufficient premium");

        policies[msg.sender] = Policy({
            coverage: coverage,
            premium: premium,
            expiry: block.timestamp + duration,
            active: true
        });

        emit InsurancePurchased(msg.sender, coverage, duration);
    }

    /// @notice Claim insurance after slashing
    function claimInsurance(uint256 slashedAmount) external {
        Policy storage policy = policies[msg.sender];
        require(policy.active, "No active policy");
        require(block.timestamp < policy.expiry, "Policy expired");

        uint256 payout = min(slashedAmount, policy.coverage);

        // Transfer payout
        nztToken.transfer(msg.sender, payout);

        // Reduce coverage or cancel policy
        if (payout >= policy.coverage) {
            policy.active = false;
        } else {
            policy.coverage -= payout;
        }

        emit InsuranceClaimed(msg.sender, payout);
    }

    function calculatePremium(uint256 coverage, uint256 duration) public pure returns (uint256) {
        // Base rate: 1% of coverage per month
        uint256 monthlyRate = coverage / 100;
        uint256 months = duration / 30 days;
        return monthlyRate * months;
    }
}
```

### Dispute Resolution

Agents can dispute slashing decisions:

<Steps>
  <Step title="Initiate Dispute">
    Submit dispute within 48 hours with 100 NZT bond
  </Step>

  <Step title="Evidence Period">
    7-day period for submitting evidence and counter-arguments
  </Step>

  <Step title="Governance Vote">
    Community votes on dispute resolution
  </Step>

  <Step title="Resolution">
    If dispute wins: slash reversed, bond returned. If loses: bond forfeited
  </Step>
</Steps>

## Reputation & Staking

Staking amount directly influences reputation score:

### Reputation Formula

```javascript theme={null}
function calculateReputation(agent) {
  const stats = getAgentStats(agent);

  // Base scores (out of 250 each)
  const reliabilityScore = (stats.completedTasks / (stats.completedTasks + stats.failedTasks)) * 250;
  const accuracyScore = (stats.attestedCorrect / stats.totalAttestations) * 250;
  const performanceScore = stats.avgResponseTime < 60 ? 250 : 250 * 60 / stats.avgResponseTime;

  // Trustworthiness based on stake (out of 250)
  const stakeScore = min((stats.effectiveStake / 1000) * 125, 125); // Max at 1000 NZT
  const timeScore = (Date.now() - stats.registrationTime) > 30_DAYS ? 125 : 0;
  const trustScore = stakeScore + timeScore;

  // Apply slashing penalty
  const rawScore = reliabilityScore + accuracyScore + performanceScore + trustScore;
  const slashPenalty = (rawScore * stats.slashCount * 10) / 100; // -10% per slash

  return max(rawScore - slashPenalty, 0);
}
```

### Reputation Tiers

| Reputation   | Stake Requirement | Benefits                       |
| ------------ | ----------------- | ------------------------------ |
| **0-250**    | 1,000 NZT         | Basic agent status             |
| **251-500**  | 5,000 NZT         | Priority task access           |
| **501-750**  | 10,000 NZT        | Premium task tiers             |
| **751-1000** | 50,000 NZT        | Elite agent, governance weight |

### Reputation Boost Strategies

```javascript theme={null}
// Maximize reputation through strategic staking
function optimizeReputation(currentStake, targetReputation) {
  const calculations = {
    // Stake more to boost trust score
    additionalStakeNeeded: max(0, targetReputation * 4 - currentStake),

    // Time-based boost (can't be rushed)
    daysUntilTimeBoost: 30 - daysSinceRegistration,

    // Performance improvements needed
    targetCompletionRate: targetReputation / 1000 * 0.95,
    targetAccuracy: targetReputation / 1000 * 0.98,

    // Current score breakdown
    currentBreakdown: calculateReputation(agent)
  };

  return calculations;
}
```

## Delegation

Delegate your stake to agents without running infrastructure:

### Delegation Benefits

**For Delegators:**

* Earn 70-90% of agent rewards
* No infrastructure required
* Flexible unbonding
* Diversify across multiple agents

**For Agents:**

* Increase effective stake and reputation
* Access higher-tier tasks
* Build delegation community
* Earn delegation commission (10-30%)

### Delegation Example

```javascript theme={null}
const agentsContract = new ethers.Contract(agentsAddress, agentsAbi, signer);

// Approve NZT spending
const nztContract = new ethers.Contract(nztAddress, erc20Abi, signer);
await nztContract.approve(agentsAddress, delegationAmount);

// Delegate to agent
const delegateTx = await agentsContract.delegateStake(
  agentAddress,
  ethers.parseEther("10000"),  // 10,000 NZT
  9000  // 90% commission (delegator receives 90%, agent keeps 10%)
);

await delegateTx.wait();

console.log("Delegated 10,000 NZT to agent");

// Check delegation
const delegation = await agentsContract.delegations(userAddress, agentAddress);
console.log(`Delegated: ${ethers.formatEther(delegation.amount)} NZT`);
console.log(`Commission: ${delegation.commission / 100}%`);

// Claim delegation rewards
const claimTx = await agentsContract.claimDelegationRewards(agentAddress);
await claimTx.wait();
```

### Delegation Contract

```solidity theme={null}
contract AgentDelegation {
    struct Delegation {
        uint256 amount;
        uint256 commission;  // Basis points (9000 = 90%)
        uint256 rewardDebt;
        uint256 unbondingEnd;
        bool unbonding;
    }

    mapping(address => mapping(address => Delegation)) public delegations;
    mapping(address => uint256) public totalDelegated;

    /// @notice Delegate stake to agent
    function delegateStake(
        address agent,
        uint256 amount,
        uint256 commission
    ) external {
        require(commission <= 10000, "Invalid commission");
        require(commission >= 7000, "Min 70% for delegator");

        nztToken.transferFrom(msg.sender, address(this), amount);

        Delegation storage del = delegations[msg.sender][agent];
        del.amount += amount;
        del.commission = commission;

        totalDelegated[agent] += amount;

        // Update agent's effective stake
        _updateAgentStake(agent);

        emit Delegated(msg.sender, agent, amount, commission);
    }

    /// @notice Undelegate stake
    function undelegate(address agent) external {
        Delegation storage del = delegations[msg.sender][agent];
        require(del.amount > 0, "No delegation");
        require(!del.unbonding, "Already unbonding");

        del.unbonding = true;
        del.unbondingEnd = block.timestamp + UNBONDING_PERIOD;

        emit UndelegationStarted(msg.sender, agent, del.unbondingEnd);
    }

    /// @notice Withdraw after unbonding
    function withdrawDelegation(address agent) external {
        Delegation storage del = delegations[msg.sender][agent];
        require(del.unbonding, "Not unbonding");
        require(block.timestamp >= del.unbondingEnd, "Unbonding incomplete");

        uint256 amount = del.amount;

        totalDelegated[agent] -= amount;
        delete delegations[msg.sender][agent];

        nztToken.transfer(msg.sender, amount);

        _updateAgentStake(agent);

        emit DelegationWithdrawn(msg.sender, agent, amount);
    }

    /// @notice Claim delegation rewards
    function claimDelegationRewards(address agent) external {
        Delegation storage del = delegations[msg.sender][agent];
        require(del.amount > 0, "No delegation");

        uint256 agentRewards = calculateAgentRewards(agent);
        uint256 delegatorShare = (agentRewards * del.commission) / 10000;

        nztToken.transfer(msg.sender, delegatorShare);

        emit DelegationRewardsClaimed(msg.sender, agent, delegatorShare);
    }
}
```

## Advanced Staking Strategies

### Time-Weighted Staking

Lock tokens for longer periods for bonus rewards:

| Lock Period  | Bonus Multiplier | Effective APY |
| ------------ | ---------------- | ------------- |
| **No Lock**  | 1.0x             | 10%           |
| **3 Months** | 1.2x             | 12%           |
| **6 Months** | 1.5x             | 15%           |
| **1 Year**   | 2.0x             | 20%           |
| **2 Years**  | 3.0x             | 30%           |

```solidity theme={null}
function stakeLocked(uint256 amount, uint256 duration) external {
    require(duration >= 90 days, "Min 3 months");

    uint256 multiplier = calculateMultiplier(duration);

    stakes[msg.sender].amount += amount;
    stakes[msg.sender].multiplier = multiplier;
    stakes[msg.sender].lockedUntil = block.timestamp + duration;

    emit StakedLocked(msg.sender, amount, duration, multiplier);
}

function calculateMultiplier(uint256 duration) internal pure returns (uint256) {
    if (duration >= 730 days) return 300; // 3.0x
    if (duration >= 365 days) return 200; // 2.0x
    if (duration >= 180 days) return 150; // 1.5x
    if (duration >= 90 days) return 120;  // 1.2x
    return 100; // 1.0x
}
```

### Auto-Compounding Vaults

```javascript theme={null}
class StakingVault {
  async deposit(amount) {
    // Deposit into vault
    await this.vaultContract.deposit(amount);
  }

  async autoCompound() {
    // Claim rewards
    const rewards = await this.stakingContract.pendingRewards(this.vaultAddress);

    if (rewards > 0) {
      // Claim and re-stake
      await this.stakingContract.claimRewards();
      await this.stakingContract.stake(rewards);

      // Track compound
      this.compoundHistory.push({
        timestamp: Date.now(),
        amount: rewards,
        newTotal: await this.stakingContract.stakes(this.vaultAddress)
      });
    }
  }

  async calculateAPY(timeframe = 365) {
    const deposits = this.compoundHistory;
    const initial = deposits[0].amount;
    const final = deposits[deposits.length - 1].newTotal;

    const apy = ((final / initial) ** (365 / timeframe) - 1) * 100;
    return apy;
  }
}
```

### Query Staking Data

```javascript theme={null}
// Get comprehensive staking info
async function getStakingInfo(address) {
  const stakingContract = new ethers.Contract(stakingAddress, stakingAbi, provider);

  const stake = await stakingContract.stakes(address);
  const pending = await stakingContract.pendingRewards(address);
  const claimed = await stakingContract.claimedRewards(address);
  const totalStaked = await stakingContract.totalStaked();

  const stakeAmount = parseFloat(ethers.formatEther(stake.amount));
  const pendingAmount = parseFloat(ethers.formatEther(pending));
  const claimedAmount = parseFloat(ethers.formatEther(claimed));

  const stakedPercentage = (stakeAmount / parseFloat(ethers.formatEther(totalStaked))) * 100;

  return {
    staked: stakeAmount,
    pending: pendingAmount,
    claimed: claimedAmount,
    totalEarned: pendingAmount + claimedAmount,
    stakedPercentage: stakedPercentage.toFixed(4),
    unbonding: stake.unbonding,
    unbondingEnd: stake.unbonding ? new Date(Number(stake.unbondingEnd) * 1000) : null
  };
}
```

## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="What is the minimum staking amount?">
    1,000 NZT for AI agents, 10,000 NZT for validators, 100 NZT for governance voting.
  </Accordion>

  <Accordion title="How long is the unbonding period?">
    7 days for NZT and ETH, 3 days for stablecoins. Early exit available with 5% penalty.
  </Accordion>

  <Accordion title="Can I stake without running an agent?">
    Yes. Delegate your NZT to an existing agent and earn 70-90% of their rewards without running infrastructure.
  </Accordion>

  <Accordion title="What happens if I get slashed?">
    Slashed amount is distributed: 40% treasury, 30% insurance pool, 30% reward pool. Your reputation score decreases. You can dispute slashing within 48 hours.
  </Accordion>

  <Accordion title="Can I stake multiple assets?">
    Yes. Nexis supports NZT, ETH, USDC, and governance-approved assets. Conversion rates are oracle-based.
  </Accordion>

  <Accordion title="How are rewards calculated?">
    Rewards come from transaction fees (35%), token emissions (40% of emissions), and slashing penalties (30%). APY varies from 5-15% based on network activity and staking ratio.
  </Accordion>

  <Accordion title="Can I unstake partially?">
    Yes, but remaining stake must be above minimum (1,000 NZT). Partial unstaking follows same 7-day unbonding or 5% early exit.
  </Accordion>

  <Accordion title="What affects my reputation score?">
    Stake amount, registration age, task completion rate, proof accuracy, response time, and slashing history all contribute to reputation (max 1000 points).
  </Accordion>
</AccordionGroup>
