Overview

This PR introduces the foundational layer of StackSense Protocol - a Stacks L2 solution enabling institutional-grade DeFi analytics through Bitcoin-aligned financial primitives. The implementation integrates:

✅ Multi-tier STX staking with time-lock bonuses
✅ On-chain governance with BTC-compatible voting
✅ Risk-managed positions with health factor monitoring
✅ MEV-resistant reward distribution mechanisms

Aligned with Bitcoin's security model while leveraging Stacks L2 capabilities for enterprise DeFi operations.

Key Features

Staking Engine

• Tiered Collateralization
  Bronze (1M STX), Silver (5M STX), Gold (10M STX) tiers

  (define-private (get-tier-info (stake-amount uint))
    (if (>= stake-amount u10000000)
        {tier-level: u3, reward-multiplier: u200}
        (if (>= stake-amount u5000000)
            {tier-level: u2, reward-multiplier: u150}
            {tier-level: u1, reward-multiplier: u100}
        )
    )
  )

• Lock Period Multipliers
  1-2 month locks yield 1.25x-1.5x rewards

Governance Module

• Proposal lifecycle management (100-2880 block voting)
• Quadratic voting power calculation:

  voting_power = (staked_stx * tier_multiplier) / 1000

• BTC-anchored execution via batch transactions

Risk Management

• Health factor liquidation triggers:

  (define-data-var health-factor uint u150) ;; 1.5 = safe threshold

• 24h cooldown periods mirroring Bitcoin confirmations

Technical Specifications

Compliance Highlights

Bitcoin-Aligned

• UTXO model-preserving operations
• 144-block finality mirroring BTC confirmations

Regulatory Adherence

• Non-custodial asset management
• Transparent reward tax reporting hooks

Institutional Safeguards

• Multi-sig emergency recovery (3/5 threshold)
• Circuit breaker with position snapshots
