7.5 EVT Excavation Limits & Earn Rate (EPS: Earnings per Spend)

The monthly EVT you can excavate is calculated as:

Monthly EVT ≈ Monthly BIND Cap × Earn Rate (EPS) × (Card Bonus) × (Event Bonus)

• Monthly BIND Cap: Set by Trust Rank (see Chapter 8).

• Earn Rate (EPS): Efficiency determined by:

  • Charm (token efficiency parameter)

  • Pararank (P-rank): NFT’s base performance

  • Multi-holding: Stability from multiple NFTs (√N diminishing curve)

  • HP / Durability: Efficiency reduction at low HP; repair stability

  • Card Bonus: Subscription or SyFu Card boosts

  • Event Bonus: Campaign multipliers

👉 The cap is not fixed by the operator — it naturally emerges as BIND cap × Earn Rate.
