Yield Aggregator
A DeFi tool that automatically moves or manages deposited crypto across yield strategies to seek better returns while reducing manual effort.
A yield aggregator is a decentralized finance service that pools users’ crypto deposits and allocates them across lending, liquidity provision, staking, or other yield-generating strategies. Instead of a user manually checking many protocols, moving funds, and claiming rewards, the aggregator’s smart contracts automate much of that process. The goal is usually to improve net yield after fees, gas costs, and strategy changes, though returns are never guaranteed.
Yield aggregators matter because DeFi opportunities can change quickly and can be costly or complex to manage one by one. For example, a user might deposit stablecoins into an aggregator vault, and the vault may lend them on one protocol, move them to another when rates improve, or compound rewards back into the position. This is similar to a robo-advisor for DeFi yield strategies, but with crypto-specific risks such as smart contract bugs, liquidity issues, market volatility, and protocol failures.
