Real-World DeFi Strategies

Strategy 1: Idle USDC Yield

You have USDC sitting in your wallet doing nothing.

1. "Show my wallet balance"
   → See how much USDC is idle

2. "What's the Kamino USDC deposit APY?"
   → Check current rates

3. "Deposit 1000 USDC to Kamino"
   → Start earning yield

4. "Show my Kamino portfolio"
   → Verify the deposit is working

Strategy 2: Leveraged Yield

Deposit SOL, borrow USDC, and deploy the borrowed USDC for more yield.

1. "Deposit 10 SOL to Kamino"
   → Use SOL as collateral

2. "Borrow 500 USDC from Kamino"
   → Borrow against your SOL (keep health factor > 2)

3. "Add liquidity to SOL/USDC on Meteora"
   → Earn LP fees with borrowed USDC

4. "Show my DeFi portfolio"
   → Monitor all positions together

Strategy 3: LP Farming

Provide liquidity to high-APR pools.

1. "Find Meteora pools for SOL"
   → Compare DLMM vs Dynamic AMM pools

2. "Add liquidity to the SOL/USDC DLMM pool"
   → Higher APR, more active management

3. "Show my Meteora positions"
   → Track fees earned

4. "Remove liquidity when done"
   → Exit when you want

Tips

• Start with Kamino lending — It's the simplest way to earn yield with low risk
• Monitor health factors — Keep your Kamino health factor above 2.0 to avoid liquidation
• Compare APYs across protocols — Rates change constantly; check multiple protocols before committing
• DLMM vs Dynamic AMM — DLMM pools have higher APR but require more active management
• Check Sanctum LSTs — If you're holding SOL long-term, liquid staking earns you yield while keeping liquidity
• Use the two-step workflow — All DeFi operations show a preview first so you can review before executing
• Track your net APY — If you're borrowing and lending, make sure your earnings exceed your borrowing costs
