7.8 Excavation Right NFT

An NFT granting the right to unlock store EVT pools.

Acquisition

• Tradable only on the SyFu marketplace

• Dropped from item boxes (Lucky Bags)

• Initially, 100% granted with each Breeding

  • Supply designed based on ecosystem balance

  • Future drop rates may be adjusted

Design Philosophy

• Scarcity: Prevent EVT inflation from oversupply.

• Growth incentive: Tied to Breeding (consuming EVT & Taiyaki), reinforcing growth cycles.

• Balance: Controlled through demand indices and automated logic.

Usage & Maintenance

• One-store-per-user rule: Only one user may hold rights per store.

• Expiration: Valid for 6 months (EVT rights expire).

• Extension:

  • Auto-extended if at least 1 excavation occurs within 6 months (resets validity from that date).

  • Manual extension with Econ/EVT also possible.

• Exercise cost: Econ required (amount per official notice).

• Display: Right-holder badge on store page (toggle ON/OFF).

Planned Additions

• First NFT Condition: Excavation Right NFTs may become a requirement for unlocking a store’s “First NFT” in future updates.
