Staking Mechanics

How to Stake

1. Acquire NZT

   Purchase NZT from DEX or earn through ecosystem participation

2. Connect Wallet

   Connect to stake.nexis.network

3. Choose Staking Method

   Direct stake (run agent) or delegate to existing agent

4. Lock Tokens

   Approve and stake NZT with chosen unbonding period

5. Earn Rewards

   Receive rewards based on network activity and your stake

Staking Workflow

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%

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

Multi-Asset Example

// 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

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:

Reward Calculation

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%

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

Compound Rewards

// 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:

1. Initiate Unbonding

   Call startUnbonding() to begin 7-day countdown

2. Wait 7 Days

   Stake remains locked, no rewards accrue during this period

3. Withdraw

   After 7 days, call unstake() to receive full stake amount

// 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:

// 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

/// @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

Slashing Protection

Agents can purchase slashing insurance:

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:

1. Initiate Dispute

   Submit dispute within 48 hours with 100 NZT bond

2. Evidence Period

   7-day period for submitting evidence and counter-arguments

3. Governance Vote

   Community votes on dispute resolution

4. Resolution

   If dispute wins: slash reversed, bond returned. If loses: bond forfeited

Reputation & Staking

Staking amount directly influences reputation score:

Reputation Formula

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

// 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

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

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

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%

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

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

// 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

What is the minimum staking amount?

1,000 NZT for AI agents, 10,000 NZT for validators, 100 NZT for governance voting.

How long is the unbonding period?

7 days for NZT and ETH, 3 days for stablecoins. Early exit available with 5% penalty.

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.

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.

Can I stake multiple assets?

Yes. Nexis supports NZT, ETH, USDC, and governance-approved assets. Conversion rates are oracle-based.

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.

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.

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).
