Yield Aggregators & Vaults

Automating the Yield Chase

DeFi offers many ways to earn yield — lending, providing liquidity, staking, farming rewards — but doing it well is complicated and time-consuming: you have to find the best opportunities, move funds around, claim and reinvest rewards, and manage risk, all while paying gas fees each time. Yield aggregators (often structured as 'vaults') automate this. You deposit your assets into a vault, and it executes a yield strategy on your behalf — putting your funds to work, automatically claiming and reinvesting (compounding) rewards, and sometimes moving between opportunities to chase the best returns. The pitch is convenience and optimisation: instead of actively managing complex DeFi positions yourself, you deposit once and let the vault's automated strategy do the work, sharing the gas costs and expertise across all depositors.

Auto-Compounding: The Core Benefit

A central feature is auto-compounding. Many yield sources pay rewards that, to maximise returns, should be regularly claimed and reinvested so you earn yield on your yield (compounding). Done manually, this means frequent transactions and gas costs, and it's easy to do sub-optimally. A vault automates it — harvesting rewards and reinvesting them regularly and efficiently, often batching the operation across all depositors so the gas cost per user is small. Over time, efficient auto-compounding can meaningfully boost returns compared to letting rewards sit un-reinvested. This is a genuine, concrete value-add: the vault turns the tedious, gas-heavy, easy-to-neglect task of compounding into an automated background process, which is a real reason yield aggregators became popular. Yearn Finance is a well-known pioneer of this vault model.

• DeFi yield is lucrative but complex and gas-heavy to manage well manually
• Yield vaults automate strategies: deploy funds, claim and reinvest rewards, optimise
• Auto-compounding (reinvesting rewards) is a core benefit, batched to save gas
• You deposit once and let the vault's strategy work — convenience plus optimisation
