How to Earn Up to 8% APY with DAI: Copy Whale Strategies for Maximum Yield

In the decentralized finance (DeFi) space, smart yield strategies are no longer exclusive to early adopters. One powerful method gaining traction involves leveraging stablecoins like DAI to generate high annual percentage yields (APYs)—up to 8%—by following the moves of crypto “whales.” These large investors optimize their capital across multiple protocols to achieve compounded returns, a technique often referred to as "eating the fish multiple times" 🐟.

This guide breaks down how you can replicate this advanced DeFi strategy step by step—without needing whale-sized capital. We’ll walk through staking ETH, converting it into yield-bearing assets, borrowing DAI, and depositing it into the DAI Savings Rate (DSR) for near-passive income.

Step 1: Stake ETH to Earn stETH on Lido

The foundation of this strategy begins with Ethereum (ETH). Instead of holding ETH idle, you can stake it via Lido, a liquid staking protocol that allows you to earn staking rewards while maintaining liquidity.

Here’s how:

1. Visit Lido’s staking platform.
2. Deposit your ETH.
3. Receive stETH (staked ETH) in return.

Staking ETH on Lido currently offers an approximate 4% annual yield, paid in additional stETH. This is just the first layer of returns.

💡 Why stake on Lido? Unlike traditional staking, where funds are locked, Lido provides a tokenized version (stETH) that can be used across DeFi platforms—unlocking composability.

Step 2: Wrap stETH into wstETH

To use stETH as collateral in lending protocols like MakerDAO, you need to wrap it into wstETH—a rebased version that reflects both your principal and accumulated rewards.

How to wrap:

1. Go to Lido’s wrap page: https://stake.lido.fi/wrap
2. Click “Unlock” if prompted.
3. Convert your stETH into wstETH.

Once wrapped, wstETH maintains a 1:1 value with stETH but increases in balance over time as rewards accrue. This makes it ideal for use as collateral in yield-generating vaults.

Step 3: Deposit wstETH into MakerDAO via Spark Protocol

Now that you have wstETH, it's time to leverage it within the Maker ecosystem. The easiest interface to interact with MakerDAO today is Spark Protocol, a user-friendly fork optimized for efficiency and low fees.

1. Navigate to SparkProtocol.
2. Connect your wallet.
3. Select wstETH as collateral.
4. Deposit your wstETH into the Spark vault.

At current market rates:

• 1 wstETH ≈ $1,830
• You can borrow up to ~68.4% of its value in DAI
• Borrowing rate: ~3.19% APY

⚠️ Important: Never borrow at the maximum threshold. Always maintain a healthy collateralization ratio to avoid liquidation during volatility.

This step unlocks leverage—you’re using appreciating collateral to generate a stablecoin (DAI), which will then be deployed for further yield.

Step 4: Borrow DAI Against Your wstETH Collateral

After depositing wstETH, proceed to borrow DAI from the Spark vault.

Key points:

• You receive interest-bearing DAI (also known as sDAI if deposited directly).
• The loan incurs a variable interest rate (~3.19%), but since DAI is stable, repayment planning is predictable.
• Your wstETH remains staked and continues earning ~4% yield from ETH staking rewards.

By borrowing DAI, you’re effectively creating capital without selling your ETH position—preserving upside while generating active income.

Step 5: Deposit DAI into DSR for Up to 8% APY

This is where the magic happens.

Instead of letting borrowed DAI sit idle, deposit it into the DAI Savings Rate (DSR)—a feature built into MakerDAO that allows users to earn interest directly on their DAI holdings.

On Spark Protocol:

1. Go to the sDAI page.
2. Deposit your borrowed DAI.
3. Begin earning up to 8% APY.

🔄 What drives the 8% yield? The DSR rate is funded by stability fees paid by borrowers across the Maker ecosystem, including those using wstETH, WBTC, and other collaterals. When demand for borrowing DAI is high, rates rise.

Now your borrowed DAI is working for you—earning more than the cost of borrowing.

Step 6: Calculate Net Yield – The Real Profit

Let’s break down the net return:

But remember—you’re only borrowing against 68.4% of your collateral value.

So:

68.4% × 4.81% = ~3.29% net gain on total principal

✅ Result: An extra 3.29% annualized return on top of your existing ETH staking rewards—without increasing your exposure or selling any assets.

This is what “copying whales” means: using DeFi composability to turn one asset into multiple income streams.

Frequently Asked Questions (FAQ)

Q1: Is this strategy safe for beginners?

While conceptually simple, this strategy involves smart contract risk, liquidation risk, and fluctuating interest rates. It’s best suited for intermediate users who understand collateral ratios and gas costs. Beginners should start small or simulate first.

Q2: What happens if ETH price drops?

If ETH declines sharply, your wstETH collateral value falls. If it breaches the minimum collateralization ratio (~145–150%), your position may be liquidated. Always leave a safety buffer—never borrow close to the limit.

Q3: Can I do this with other tokens?

Yes! Similar strategies work with WBTC, rETH, and other liquid staking tokens supported by MakerDAO or Spark. However, wstETH is among the most efficient due to its strong liquidity and consistent yield.

Q4: Why use Spark instead of MakerDAO directly?

Spark Protocol offers a cleaner UI, lower fees, and faster transactions while interfacing with the same underlying Maker system. It simplifies access without sacrificing security.

Q5: Are there tax implications?

In many jurisdictions, borrowing DAI (a stablecoin) isn’t a taxable event—but spending or trading it might be. Consult a tax professional familiar with crypto regulations in your country.

Q6: How often should I monitor my position?

Check weekly during volatile markets. Rates change dynamically, and sudden price swings could threaten your health factor. Set up alerts via DeFi Pulse or Zapper for peace of mind.
