# Solana Unchained Vault

The staking process

The Vault is a non‑custodial staking contract that allows users to lock $UCHN tokens in exchange for yield and enhanced platform features.

**Staking mechanics:**

* Users choose a lock‑up period: 30, 90, 180, or 365 days.
* Longer lock‑ups receive a larger share of the reward pool and fee distributions.
* Early withdrawal is permitted but forfeits 50% of accrued rewards (the forfeited amount is redistributed to remaining stakers).

**Reward sources:**

1. Dedicated staking reward pool – 10,000,000 tokens (10% of total supply) allocated at genesis, vested linearly over 4 years.
2. Protocol fee sharing, A portion of all fees generated by:
3. AI Tool Hub (70% of fees go to stakers)
4. Infrastructure protocols (Commerce, Recovery, Inheritance)
5. Unchained Wallet commerce markup

**Dynamic yield calculation:**\
The exact APY for each lockup period is calculated dynamically per epoch (e.g., every 7 days) based on:

* Total number of tokens staked across all lockup periods.
* Distribution of stakes across different lock durations (longer locks receive a higher weight).
* Fee revenue collected during the epoch.
* Remaining balance in the staking reward pool.

Estimated yield ranges (subject to change):

| Lockup Period | Estimated APY Range |
| ------------- | ------------------- |
| 30 days       | 8% – 12%            |
| 90 days       | 12% – 18%           |
| 180 days      | 18% – 25%           |
| 365 days      | 25% – 35%           |

**Staking tiers and feature unlocks:**

| Staked Tokens (minimum) | Approx. Value at Launch ($0.50/token) | Tier Name  | Unlocked Features                                                         |
| ----------------------- | ------------------------------------- | ---------- | ------------------------------------------------------------------------- |
| 5,000                   | $2,500                                | Pro        | Premium AI tools (unlimited requests, advanced models)                    |
| 25,000                  | $12,500                               | Elite      | Priority queue for AI processing + 0.5% fee discount on commerce protocol |
| 100,000                 | $50,000                               | Governance | Voting rights + revenue share from Infrastructure protocols               |
| 500,000                 | $250,000                              | Whitelabel | SDK access for third‑party dApps (recovery/inheritance)                   |

{% hint style="info" %}
Why this matters: Staking in the Vault is designed for long‑term participants who want both yield and enhanced utility. The combination of a finite reward pool and fee‑sharing ensures that yields are sustainable and aligned with the platform’s real economic activity.
