Vault

What vaults do

Common functions:

• Pool user deposits — aggregate capital.
• Execute strategy — automated yield-generating operations.
• Distribute returns — proportional to deposits.
• Charge fees — typically performance and/or management.

The vault abstracts complex operations behind a simple deposit/withdraw interface.

Common vault types

Several categories:

• Yield aggregators — auto-rotate between protocols (Yearn, Beefy).
• Liquidity manager vaults — manage Uniswap V3 positions (Gamma, Arrakis).
• Strategy vaults — execute specific trades (delta-neutral, basis trade).
• Lending vaults — deposit into lending protocols.
• Insurance vaults — back insurance protocols.
• Restaking vaults — manage restaking positions.

Each has different risk-return profiles.

How vaults make money

Typical mechanics:

• Strategy execution — earn yield from underlying activities.
• Compounding — auto-reinvest earnings for compound returns.
• Optimization — frequently update positions for best returns.
• Fee structure — performance fees (10-20% of profits) and/or management fees.

Net yields after fees vary widely.

Why use a vault

Several rationales:

• Convenience — single deposit instead of complex management.
• Gas efficiency — pooled operations spread costs across users.
• Strategy access — strategies that require expertise or capital.
• Auto-compounding — captures small yields that wouldn't justify manual gas.

Vaults are common entry point for passive yield-seekers.

Risks

Several concerns:

• Smart contract risk — vault code can have bugs.
• Strategy risk — underlying strategy may fail.
• Underlying protocol risk — vault inherits risks of protocols it uses.
• Centralization risk — strategists can change strategies.
• Fee drag — fees can erode returns.

Vaults concentrate multiple risk layers.

Notable vault providers

Major examples:

• Yearn — pioneer yield aggregator.
• Beefy — multi-chain auto-compounding.
• Pendle — yield trading.
• Gamma, Arrakis — concentrated liquidity management.
• Etherfi, Renzo — restaking vaults.

Each has different niches and risk profiles.

What individuals should know

For users:

• Vaults simplify complex DeFi interactions.
• Read strategy docs — understand what vault does.
• Audit history — favor audited vaults.
• TVL and track record — established vaults have less risk.
• Fee structure — performance fees can be substantial.

For yield seekers:

• Compare net yields after fees.
• Don't concentrate in any single vault.
• Be aware of underlying protocol risks.

Vaults are foundational DeFi infrastructure for passive yield. They simplify complex operations but stack risks; understanding the strategy and underlying protocols is essential to informed use.
