### 🤖 AI-Powered Strategy (EigenAI)

Our intelligent AI assistant powered by **EigenAI (deepseek-v31-terminus)** analyzes your goals and recommends the optimal strategy:

**How it works:**

1. Enter your savings goal in plain language (English or Indonesian)
2. AI analyzes risk tolerance, timeline, and objectives
3. Get 3 strategy recommendations with detailed reasoning
4. Each strategy includes specific Sui DeFi protocol allocations

**Strategy Options:**

| Strategy         | Target APY | Protocols                                               | Risk Level |
| ---------------- | ---------- | ------------------------------------------------------- | ---------- |
| **Conservative** | \~4%       | Scallop (50%), Navi (30%), Aftermath (20%)              | Low        |
| **Balanced**     | \~8%       | Scallop (35%), Cetus (35%), Turbos (20%), Navi (10%)    | Medium     |
| **Aggressive**   | \~15%      | Cetus (40%), Kriya (30%), Turbos (20%), Aftermath (10%) | High       |

**AI explains WHY** a strategy suits you, not just WHAT to choose.

### 💰 Proportional Yield Distribution

Rewards are distributed fairly based on consistency — **not speculation, not penalties**.

**How it works:**

```
Your reward = (your_deposits / total_deposits) × total_yield
```

**Example:** 5-period room (weekly or daily), 10 USDC total yield

* Alice deposits 5/5 times → Gets 45.45% of yield (4.5 USDC)
* Bob deposits 4/5 times → Gets 36.36% of yield (3.6 USDC)
* Carol deposits 2/5 times → Gets 18.18% of yield (1.8 USDC)

**Key principles:**

* ✅ Principal always returned 100%
* ✅ Yield shared proportionally
* ✅ No penalties or slashing
* ✅ Miss deposits = less yield, not lost capital

***

### 🆓 Gasless Transactions

**Zero gas fees for all user actions.**

Backend sponsors all transaction costs:

* Join room → Gasless ✅
* Periodic deposits (daily/weekly) → Gasless ✅
* Claim rewards → Gasless ✅

Users only need USDC to participate. No SUI required.

**How?** Multi-signature sponsorship — user signs transaction, backend adds sponsor signature and pays gas.

### 👥 Group Savings Advantage

**Mathematical benefit of saving together:**

Larger vaults generate better yields in DeFi protocols. Even if you get a smaller percentage of the yield pool, the absolute amount is often higher.

**Example:** Alice saves 500 USDC over 5 periods

| Scenario     | Vault Size | Total Yield | Alice Gets      | ROI          |
| ------------ | ---------- | ----------- | --------------- | ------------ |
| Solo         | 500 USDC   | 4.2 USDC    | 4.2 USDC (100%) | +0.84%       |
| With Friends | 1100 USDC  | 10 USDC     | 4.5 USDC (45%)  | **+0.91%** ✅ |

*Period can be daily or weekly based on room configuration.*

**Result:** You earn MORE by saving together, plus gain community accountability.

| **Yield source**         | Simulated (on-chain) | Real DeFi protocols         |
| **Principal protection** | ✅ Yes                | ✅ Yes                       |
| **Gasless UX**           | ✅ Yes                | ✅ Yes                       |
| **AI recommendations**   | ✅ Yes (EigenAI)      | ✅ Yes (EigenAI)             |
| **Protocol integration** | Simulated APY rates  | Live Scallop/Navi/Cetus     |
| **APY**                  | Fixed (4%/8%/15%)    | Variable (market-dependent) |

> **Note:** Current testnet uses simulated yield. Mainnet will deploy funds to real Sui DeFi protocols for genuine yield generation.
