Cơ chế auto-compound:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Harvest rewards từ farm
2. Swap rewards → base token
3. Deposit lại vào pool
4. Lặp lại định kỳ

Ví dụ:
$1,000 deposit với 50% APR
• Manual (compound monthly): ~$1,628/năm
• Auto-compound (hourly): ~$1,648/năm

Yearn Finance (YFI):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• OG yield aggregator
• Ethereum mainnet
• "Vaults" với strategies
• 2% management + 20% performance fee

Beefy Finance:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Multi-chain (30+ chains)
• Đa dạng strategies
• Community-driven
• ~4.5% fee trên profits

Vault Types:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Single Asset Vaults:
┌─────────────────────────────────────────┐
│ • Deposit 1 loại token                  │
│ • Ví dụ: ETH vault, USDC vault          │
│ • Đơn giản, ít IL risk                  │
└─────────────────────────────────────────┘

LP Token Vaults:
┌─────────────────────────────────────────┐
│ • Deposit LP tokens (ETH-USDC LP)       │
│ • Auto-compound LP rewards              │
│ • Có IL risk                            │
└─────────────────────────────────────────┘

Strategy Examples:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Strategy A - Lending:
1. Deposit USDC
2. Lend trên Aave → aUSDC
3. Stake aUSDC → thêm rewards
4. Compound tất cả

Strategy B - LP Farming:
1. Deposit ETH-USDC LP
2. Stake LP trên farm
3. Harvest rewards
4. Swap → thêm LP
5. Restake

1. Time-saving
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Không cần claim thủ công
• Không cần monitor liên tục
• Automated 24/7

2. Gas Optimization
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Batched transactions
• Shared gas costs giữa users
• Compound khi gas thấp

3. Higher APY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Frequent compounding
• Optimized strategies
• Professional management

4. Simplicity
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Deposit và quên
• Không cần chuyên môn sâu
• UI/UX thân thiện

1. Smart Contract Risk
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Aggregator contract có thể bị hack
• Strategy contracts vulnerable
• Multiple layers of risk

2. Strategy Risk
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Strategy có thể fail
• Underlying protocol risk
• Impermanent loss (LP vaults)

3. Fee Structure
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Management fees
• Performance fees
• Withdrawal fees (một số)
• Có thể ăn vào profit

4. Complexity Risk
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Nhiều layers = nhiều risk
• Khó trace vấn đề
• Dependencies phức tạp

Risk Matrix:
┌─────────────────────────────────────────┐
│ Stablecoin vaults: Lower risk          │
│ Blue-chip LP:      Medium risk          │
│ Exotic strategies: Higher risk          │
└─────────────────────────────────────────┘

APR (Annual Percentage Rate):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Simple interest
• Không compound
• $1,000 @ 50% APR = $1,500/năm

APY (Annual Percentage Yield):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Compound interest
• Thường cao hơn APR
• $1,000 @ 50% APY ≈ $1,648/năm (daily compound)

Chú ý khi so sánh:
• Một số hiển thị APR, một số APY
• APY nghe "đẹp" hơn
• Luôn so sánh cùng đơn vị
