Introduction
Yield aggregators have revolutionized decentralized finance (DeFi) by automating yield farming, maximizing returns while minimizing manual effort. In 2025, with DeFi's total value locked (TVL) surpassing $150 billion, these platforms are essential for optimizing asset allocation across protocols. This article explores how yield aggregators work, their strategies, top platforms, and their role in enhancing DeFi returns.
How Yield Aggregators Work
Yield aggregators are DeFi platforms that pool user funds and allocate them to the highest-yielding opportunities across protocols. They act as automated portfolio managers, using smart contracts to scan, invest, and reinvest assets in liquidity pools, lending platforms, or staking mechanisms.
Key Features:
- Auto-compounding: Reinvests rewards to boost returns.
- Dynamic allocation: Shifts funds to the best-performing protocols.
- Gas optimization: Reduces transaction costs by bundling operations.
Example: A user deposits USDC into a Yearn Finance vault, which dynamically allocates funds between Aave, Compound, and Curve to secure the best APY (e.g., 10–20%).
