7.4 EVT Issuance & Circulation (Economics)

This page explains how EVT increases, how it is used, and why it is designed to be inflation-resistant from a system perspective. For EVT, tokenomics is centered on issuance logic and circulation logic, not a simple “allocation table.”

What you’ll learn on this page

• How EVT is issued (increases)

• How EVT is spent and how supply is naturally constrained

• Why inflation control is built into the design

1) The “Increase” side: Controlled by BIND and pool design

EVT is excavated (earned) through BIND, which links payment data to user activity. Because of this, EVT is not designed to increase infinitely just because users participate.

In SyFu, EVT issuance is controlled through three mechanisms:

• Pool structure (where EVT comes from)

• Cap design (how much can be excavated)

• Difficulty adjustment (the pace of excavation)

Two-layer structure: National Pool / Store Pool

EVT is managed through a two-layer pool structure (see 7.6 for details):

• National Pool

• Store Pool

With this design, the excavatable supply is managed at both the country level and the store level, preventing supply from expanding all at once.

Difficulty adjusts automatically based on National Pool status

As the National Pool is consumed (remaining balance decreases), excavation efficiency (i.e., how easy or strict the conditions are) adjusts automatically (see 7.6 / 7.7).

In short:

the more excavation progresses, the more the excavation pace tends to slow down.

This is a self-adjusting structure.

2) The “Use” side: EVT is designed to circulate as it is spent

EVT is not meant to be earned and held indefinitely. It is designed to circulate through in-game usage, which in turn helps constrain circulating supply.

Major circulation actions

• Breeding Spent EVT is locked, and a portion is burned. Example: lock + 7.5% burn

• Naturalization (Uncommon → EVT) Part of the locked amount may be returned, while a portion is burned. Example: an additional 7.5% burn (15% total reduction round-trip)

• Lifespan recovery In recovery flows that consume NFTs, NFT supply is also reduced at the same time. Example: using an Uncommon burns the NFT, and the related locked EVT is also burned

Key takeaway

Within EVT’s design:

• earned (supply)

• spent (consumption)

• reduced (burn)

are integrated into the same game loop.

As a result, EVT is not a “mint-and-expand forever” structure — it is designed so that supply can be naturally constrained through ongoing circulation.

3) Right Scroll is an “unlock gear”

Right Scroll (Excavation Right NFT) unlocks excavation rights on the Store Pool side (see 7.9).

It is not just an item — it functions as a gear that can adjust the excavation pace depending on ecosystem conditions.

• The more stores are unlocked, the more excavatable supply accumulates in that country

• To avoid excessive supply expansion, the system balances this with National Pool difficulty and other controls

• Store Pool excavation efficiency can increase (example: +20%)

Summary: EVT is designed as a loop of “increase, use, control”

EVT’s economic design is built on three integrated components:

1. Manage issuance through BIND and pools

2. Circulate through in-game spending, naturally constraining supply

3. Adjust excavation pace through Right Scroll and difficulty mechanisms

Because of this structure, EVT is not a simple issuance-based token — it is designed so that supply-demand dynamics evolve in sync with actual usage.
