Yield Aggregator
A yield aggregator is a DeFi protocol that automatically allocates and rebalances users’ deposited assets across multiple lending, liquidity, or farming venues to optimize risk-adjusted returns.
✦ Key Insight
It saves traders the time and gas of manually hunting the highest yields. Aggregators compound rewards, switch strategies as rates change, and often provide a single deposit token representing the optimized position, ideal for passive or semi-passive capital deployment.
✕ Common Misconceptions
Ignoring strategy risk or smart-contract risk of the underlying protocols; chasing advertised APYs without checking historical performance or fees; depositing into unaudited aggregators.
Detailed Explanation
Why it matters:
How It Works: Users deposit into a vault. Smart contracts or keepers monitor rates across protocols (Aave, Compound, Curve, etc.), move funds to the best opportunities, harvest rewards, and compound them. Strategies can be simple (highest APY) or complex (leveraged, hedged).
FAQs:
Do I keep custody?
Usually yes, non-custodial vaults.
Are yields guaranteed?
No, they fluctuate and carry risk.
Gas costs?
Often socialized or optimized by the protocol.
