Cryptomonnaies et DeFi : How to Generate Yields on Aave in 2025

·

Decentralized Finance (DeFi) has revolutionized the way crypto holders can grow their digital assets. Among the leading protocols, Aave has emerged as a cornerstone for generating passive income in a trustless, transparent, and decentralized environment. By allowing users to lend their crypto assets through liquidity pools, Aave enables them to earn interest—similar to a high-yield savings account, but powered by blockchain technology.

This guide walks you through the process of earning yields on Aave in 2025, including practical steps, real-world examples, and strategic tips to maximize returns while managing risk.

What Is Aave? The Leading DeFi Lending Protocol

Aave is a decentralized lending and borrowing platform built on blockchain networks. Originally launched in 2017 as ETHLend, it evolved into one of the most secure and feature-rich DeFi protocols. Today, Aave operates across 13 major blockchains, including Ethereum, BNB Chain, Avalanche, and multiple Layer-2 solutions like Base, offering users flexibility and reduced transaction costs.

When you deposit crypto into Aave, your assets are added to a liquidity pool and made available to borrowers. In return, you earn interest—paid out continuously in real time.

One of Aave’s unique features is the issuance of aTokens upon deposit. For example:

These aTokens represent your share of the pool and automatically accrue interest over time, increasing in value as yields compound.

With Aave V3, the latest iteration introduces enhanced capital efficiency, cross-chain functionality, and improved risk management tools—making it easier than ever to optimize yield generation across multiple networks.

How to Earn Yields on Aave: Step-by-Step Guide

Aave supports over 140 liquidity pools across its supported chains. Choosing the right pool depends on your risk tolerance, preferred asset, and network conditions.

To identify the most profitable opportunities, use DeFiLlama’s Yield section, which tracks real-time APYs (Annual Percentage Yields) across all Aave markets: DefiLlama – Aave Yields. You can filter by chain, asset, and APY to find optimal returns at any given moment.

Let’s explore two high-potential yield strategies available in 2025.

Earning Yield on ETH via WETH Pool (Aave V3 – Base)

For Ethereum holders, the WETH pool on Base offers an attractive entry point with an APY of around 2% at the time of writing. While this may seem modest compared to volatile assets, it reflects stability and consistent demand for leveraged positions and yield strategies on this low-cost Layer-2 network.

Why Base?

Steps to Deposit ETH into Aave’s WETH Pool on Base:

  1. Set up a Web3 wallet like MetaMask or Rabby Wallet.
  2. Bridge ETH to Base using a trusted cross-chain bridge (e.g., Base’s native bridge).
  3. Visit the Aave WETH pool page on Base.
  4. Connect your wallet and ensure it's set to the Base network.

  5. Deposit either:

    • ETH: Automatically wrapped into WETH
    • WETH: Direct deposit
  6. Start earning interest immediately in the form of aWETH.

Your balance will grow gradually as aWETH accumulates yield.

Earning Yield on Stablecoins via USDC Pool (Aave V3 – Base)

Stablecoin investors seeking low-volatility returns can benefit from the USDC pool on Base, which currently offers an impressive 14.5% APY. This high yield is driven by strong borrowing demand from traders and leveraged strategies within the Base ecosystem.

Steps to Deposit USDC into Aave:

  1. Swap ETH for USDC on a decentralized exchange like Aerodrome Finance (Base-native DEX).
  2. Go to the Aave USDC pool on Base.
  3. Approve USDC spending (one-time transaction).
  4. Confirm deposit amount and complete the transaction.
  5. Receive aUSDC, which earns interest continuously.

This strategy is ideal for risk-averse users who want exposure to DeFi without market volatility.

Monitoring Your Positions on Aave

After depositing funds, use Aave’s Dashboard to track your portfolio:

The dashboard provides full transparency, helping you stay informed about performance and risks.

Advanced Strategy: Use Deposits as Collateral to Borrow

Aave allows you to use deposited assets as collateral to borrow other cryptocurrencies—without withdrawing your initial investment. This means you can:

For example:

This feature enables sophisticated financial strategies like leveraged staking or hedging.

Understanding Liquidation Risk

Borrowing on Aave requires careful risk management. Loans are over-collateralized, meaning your collateral value must always exceed your debt.

Aave uses a Health Factor metric:

If the price of your collateral drops too quickly (e.g., ETH plunges), Aave may automatically liquidate part of your position to repay the loan.

Example:

To avoid this:

Tips to Optimize Yields on Aave

1. Minimize Transaction Fees by Choosing the Right Chain

While Ethereum offers deep liquidity, its high gas fees can erode profits—especially for small deposits.

Layer-2 networks like Base or Arbitrum offer near-zero fees, making them ideal for frequent interactions or smaller portfolios. Even if APY is slightly lower than on Ethereum, net returns are often higher after cost savings.

2. Diversify Across Chains and Assets

Spread your investments across:

This reduces exposure to single-chain risks and captures higher yields where demand is strongest.

Use DeFiLlama to compare cross-chain APYs and rebalance when better opportunities arise.

3. Stay Aware of Smart Contract and Market Risks

Despite rigorous audits, smart contract vulnerabilities remain a concern in DeFi. Hacks have occurred—even on well-established platforms.

Additionally:

Always do your own research and only invest what you can afford to lose.

Frequently Asked Questions (FAQ)

Q: Is Aave safe to use in 2025?

Yes, Aave remains one of the most audited and battle-tested DeFi protocols. However, no platform is 100% risk-free. Always verify contract addresses, use trusted wallets, and avoid sharing private keys.

Q: Can I lose money on Aave?

Yes—primarily through:

Proper risk management minimizes these dangers.

Q: What’s the difference between APR and APY?

APR (Annual Percentage Rate) shows simple interest. APY includes compounding interest, which reflects actual earnings more accurately—especially in DeFi where compounding happens continuously.

Q: Do I pay taxes on Aave yields?

In most jurisdictions, yes. Crypto earnings from lending are typically considered taxable income. Consult a tax professional for guidance based on your location.

Q: Can I withdraw my funds anytime?

Yes—Aave offers high liquidity. You can withdraw deposited assets at any time, minus any accrued interest adjustments during processing.

Q: Are stablecoin yields sustainable?

High stablecoin yields often reflect temporary market dynamics (e.g., promotional incentives or high borrowing demand). Monitor trends via DeFiLlama to spot when rates normalize.
