# MetaVaults

### Overview

MetaVaults provide an **aggregation layer for onchain strategies**, enabling a single vault to allocate liquidity across multiple onchain destinations under a unified interface. They are designed to power portfolio-style products where capital is distributed across several strategies, vaults, or apps and protocols while users interact with only one vault position.

A MetaVault abstracts strategy composition and capital routing, allowing allocation logic to be expressed onchain without exposing users to operational complexity.

### Design Goals and Key Characteristics

MetaVaults are built with the following principles in mind:

* **Strategy aggregation**\
  Each MetaVault represents a portfolio of underlying strategies rather than a single execution path.
* **Composable allocations**\
  Capital can be routed to multiple onchain destinations, including other vaults and direct protocol integrations, in a modular and extensible way.
* **Unified user interface**\
  Users deposit into and redeem from a single vault, regardless of how many strategies are used internally.
* **Onchain transparency**\
  All allocations, balances, and interactions are executed and accounted for onchain, enabling full auditability and integration with external tooling.
* **Scalable orchestration**\
  MetaVaults enable reuse of existing strategies and integrations, supporting rapid iteration without changes to the user-facing vault interface.

### High-Level Functionality

At a high level, a MetaVault functions as follows:

* Users deposit assets into the MetaVault and receive shares representing proportional ownership of the aggregated strategy.
* Deposited liquidity is allocated across a configurable set of underlying onchain destinations according to the vault’s strategy logic.
* Allocation can be adjusted over time as the strategy evolves, while users remain exposed through a single vault position.
* The value of MetaVault shares reflects the combined performance of all underlying allocations, and redemptions are handled at the MetaVault level.
