Chapter 7: Staking and Yield System

7.1 Multi-tier Staking System

7.1 Multi-tier Staking System

TreFi Magic Cube has established a comprehensive multi-tier staking system, providing users with flexible staking options and diverse yield opportunities.

7.1.1 Flexible Staking Options

Three-tier Staking Structure:

Staking Type	Lock-up Period	Expected APY	Liquidity	Additional Benefits
Flexible Staking	No lock-up	5-8% APY	Anytime access	Basic yield rights
Fixed-term Staking	30-90 days	12-18% APY	Term-locked	Enhanced yield rights
Super Staking	180+ days	25%+ APY	Long-term lock	Governance privileges + priority yield

Detailed Parameters for Each Tier:

• Flexible Staking:

  • Zero lock-up period, anytime access flexibility

  • Base yield rate of 5-8%, daily compound calculation

  • Suitable for short-term fund planning and liquidity management

• Fixed-term Staking:

  • 30-day term: 12% APY, medium yield level

  • 90-day term: 18% APY, higher yield return

  • Non-withdrawable during lock-up period, automatic release upon maturity

• Super Staking:

  • 180-day term: 25% APY, highest yield tier

  • 360-day term: 30% APY, maximum yield return

  • Grants governance voting rights and protocol revenue sharing

7.1.2 Technical Implementation Architecture

Core Smart Contract Functions:

function stake(uint256 amount, uint256 lockPeriod) external {
    require(amount > 0, "Amount must be positive");
    require(lockPeriod >= MIN_LOCK, "Lock period too short");
    
    // Calculate reward multiplier
    uint256 multiplier = calculateMultiplier(lockPeriod);
    uint256 rewards = amount * multiplier * baseRate / 1e18;
    
    _mint(msg.sender, rewards);
    emit Staked(msg.sender, amount, lockPeriod);
}

Parameter Description:

• amount: Staking amount, must be greater than 0

• lockPeriod: Lock-up period, cannot be less than minimum lock period

• multiplier: Reward multiplier, dynamically calculated based on lock period

• baseRate: Base interest rate, adjusted according to protocol parameters

• rewards: Calculated reward amount
