# Chapter 3 · Genesis Stacking

A bonding curve written into the contract

### 3.1 The Bonding Curve: Every Token Born on the Curve

52,500,000 VITA (25% of supply) are minted along a <mark style="color:$warning;">**bonding curve**</mark> written into the contract in advance. The curve is divided into 100 consecutive price tiers; every VITA is born by being bought off the curve with real USDT, and each step of subscription moves the price one notch up. The first token costs about 0.100 USDT, the last 0.200 USDT — exactly <mark style="color:$warning;">**2×**</mark> the starting point. The earlier you climb, the lower the step beneath you; yet there is only one curve for everyone, and the rules are identical for all:

### 3.2 The Quantity Function: A Fish-Belly Normal Distribution

Price is the curve's first coordinate; quantity is its second. Per-tier issuance follows a discrete normal distribution with mean μ = 50.5 and standard deviation σ = 20; after integer rounding adjustment the hundred tiers sum to exactly 52,500,000:

| -------------------------------------------- | ------------------------- | ------------------------------- | ------------------------------------- |
| <mark style="color:$warning;">1</mark>       | 0.100                     | about 49,579                    | Start · lowest price, smallest supply |
| <mark style="color:$warning;">25</mark>      | ≈ 0.124                   | about 460,000                   | Ascent · supply widening              |
| <mark style="color:$warning;">50 / 51</mark> | ≈ 0.150                   | about 1,060,052 each            | Peak · concentrated release           |
| <mark style="color:$warning;">75</mark>      | ≈ 0.175                   | about 460,000                   | Descent · supply contracting          |
| <mark style="color:$warning;">100</mark>     | 0.200                     | about 49,579                    | End · highest price, smallest supply  |

### 3.3 The Intent Behind the Curve

* <mark style="color:$warning;">**Early tiers (1–30): low price, small supply**</mark> — the steepest price advantage is reserved for the earliest believers, while limited supply naturally prevents whales from sweeping whole tiers, so the first genesis holdings are widely dispersed.
* <mark style="color:$warning;">**Middle tiers (31–70): volume opens up**</mark> — roughly seventy percent of the supply is released as consensus warms, price and scale climbing together, giving the main building period the deepest capacity.
* <mark style="color:$warning;">**Late tiers (71–100): higher price, tighter supply**</mark> — supply narrows tier by tier as price approaches double, and genesis closes in scarcity rather than surplus, leaving a clean price anchor for the secondary market.

### 3.4 Execution Rules

* <mark style="color:$warning;">**Transparent state**</mark>: the contract publishes the current tier price, remaining amount and cumulative stacking in real time.
* <mark style="color:$warning;">**Per-address limits**</mark>: each address may stack between 200 and 10,000 USDT; the entrance is equally open to all.
* <mark style="color:$warning;">**Cross-tier splitting**</mark>: when funds span several tiers the contract settles tier by tier. Example: 2,000 tokens remain in tier 1 and a user commits 500 USDT — the contract first settles 2,000 at 0.100 (200 USDT), then automatically settles the remaining 300 USDT at the tier-2 price of 0.10101 for about 2,970 tokens.
* <mark style="color:$warning;">**Sell out, move up · then the curve closes**</mark>: a sold-out tier advances automatically to the next; the moment tier 100 sells out, the bonding curve is <mark style="color:$warning;">**closed forever (Curve Closed)**</mark> and the minting interface is sealed with it. There is no second genesis; from then on all VITA circulation happens on the open market.
* <mark style="color:$warning;">**Phase switch**</mark>: once all 52,500,000 are stacked, the contract sets isMiningActive = true and opens the Strategy Vault. The shift from genesis to operation is executed by code; no one can bring it forward or hold it back.
* <mark style="color:$warning;">**Two-track release**</mark>: of the VITA obtained through stacking, **50%** may be withdrawn to the wallet and traded freely once the curve closes and stacking ends; the other **50%** is realized as WBTC by building LP and joining the Strategy Vault.

### 3.5 VPGM: From Identity to Network Consensus

Genesis stacking is the first-stage booster of the VITA Protocol Growth Model (VPGM): it completes value distribution (VITA received, factor V recorded) while granting the right to claim crystals (identity prepared), paving the way for the activation described in Chapter 4 — capital flow, identity flow and network flow are bound to one path from the source.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://vitaprotocol.gitbook.io/vita/vita-protocol/tokenomics/chapter-3-genesis-stacking.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
