Yield aggregators are DeFi protocols that automatically optimize and compound users' crypto assets across multiple yield farming opportunities, vaults, and liquidity pools. By automating complex strategies, they help users maximize returns, save time, and reduce transaction costs in the fast-evolving world of decentralized finance.
How do yield aggregators work?
- Deposit: Users deposit tokens (e.g., USDC, ETH, stablecoins) into aggregator vaults or pools.
- Strategy selection: Aggregators deploy assets into the most profitable DeFi protocols (lending, farming, staking).
- Auto-compounding: Rewards are harvested and reinvested automatically to maximize APY.
- Rebalancing: Strategies are adjusted as market conditions change to optimize yield.
- Withdrawal: Users can withdraw their assets (plus earned yield) at any time.
Aggregator vs manual yield farming
| Feature | Yield Aggregator | Manual Yield Farming |
|---|---|---|
| Strategy | Automated, optimized | User-managed |
| Compounding | Auto, frequent | Manual, less frequent |
| Gas fees | Shared among users | Paid by each user |
| Time required | Minimal | High |
| Risk | Smart contract, protocol | Smart contract, user error |
| Returns | Often higher (optimized) | Varies (depends on user skill) |
