Yield Aggregators

Yield aggregators sit on top of vaults and lending markets, continuously routing capital toward the best risk-adjusted returns available. They handle auto-compounding, rebalancing, and gas optimization automatically, turning fragmented yield sources into a single, continuously optimized return stream. If vaults define how a strategy works, aggregators decide where capital moves to make the most of it.

At a glance:

Yield aggregators sit on top of vaults and lending markets, continuously routing capital toward the best available risk-adjusted returns without requiring manual intervention from depositors.

Unlike risk curators, aggregators do not design vaults or set parameters. Their job is to move capital efficiently across existing strategies, handle auto-compounding, and reduce gas costs through batching.

Aggregators amplify returns but also inherit risks from every protocol in their chain. Smart contract risk, composability risk, and variable APYs all stack on top of each other.

Top Yield Aggregators

How yield aggregators work

Deposit: Users deposit assets (such as ETH or stablecoins) into the aggregator's vault. Capital is pooled so strategies can run efficiently at scale.

Allocate: Smart contracts route funds into the most attractive vaults, lending markets, or liquidity pools. Allocation is dynamic: yields are monitored and capital shifts as the opportunity set changes.

Compound: Rewards (governance tokens, interest, LP fees) are harvested automatically, sold for the base asset, and reinvested. This continuous compounding is where most of the yield outperformance over manual strategies comes from.

Rebalance: Liquidity shifts between vaults as APYs, incentives, and risk conditions evolve. Rebalancing accounts for volatility, utilization rates, and gas costs to maximize net return, not just raw APY.

Withdraw: Users can redeem at any time, receiving their original assets plus accumulated yield. No manual strategy unwinding required.

Types of yield aggregators

Single-protocol aggregators optimize returns within one specific ecosystem. They route capital between vaults and strategies within that protocol rather than crossing into others. Example: Morpho Blue optimizers.

Cross-protocol aggregators move liquidity across many vaults and lenders to find higher yield across chains and ecosystems. These are the most common type of retail-facing aggregator. Examples: Yearn Finance, Beefy.

Smart wallet aggregators embed routing logic directly into the wallet interface. Users interact with a simple interface while the wallet handles strategy selection and reallocation. Examples: Summer.fi, Instadapp-style automation.

Institutional aggregators provide customizable vaults and programmable strategies for funds, treasuries, and DAOs. Examples: Enzyme, Avantgarde.

Benefits and risks for depositors

Why aggregators add value

Simplified access to DeFi yield: no need to monitor APYs or move funds manually across protocols.

Higher net yield: auto-compounding boosts returns beyond raw protocol rates, especially for long-duration positions.

Lower gas costs: pooled execution makes complex strategies accessible at any deposit size.

Diversification: exposure to multiple markets via a single deposit.

Time efficiency: passive yield without operational overhead.

Risks to understand

Smart contract risk: aggregators are complex smart contracts, and vulnerabilities at the aggregator level can affect the entire position, not just one protocol.

Composability risk: aggregators rely on multiple external protocols. If one fails, the entire strategy chain is affected.

Variable performance: changing APYs, liquidity conditions, and incentive programs can significantly affect net yield relative to expectations.

Liquidation risk: looping or leveraged strategies within an aggregator can be liquidated if markets move sharply.

Yield aggregators vs. risk curators: what is the difference?

Risk curators shape the structure of individual vaults. Aggregators amplify the economic outcome by routing capital across those structures efficiently.

Function	Risk Curators	Yield Aggregators
