# Overview

#### Introduction

Aera powers onchain vaults with off chain intelligence. Aera vaults can be deployed and configured to power various off chain strategies ranging from treasury management for DAOs to complex yield strategies, earn programs and other multi-depositor use cases.

Each vault has one or more guardians that take onchain actions while complying to specified constraints. Vaults immediately revert guardian transactions that call un-whitelisted contracts or don't comply with calldata constraints.

#### Key Features

* **Trustless use of guardians**. Aera guardians can optimize their execution off chain while the vault is being protected onchain. Efficient use of Merkle trees allows guardian transactions to be heavily constrained without impacting gas costs.
* **Access the entire universe of DeFi assets**. Aera's constraints are flexible enough to support interactions with a wide variety of DeFi (and even non-DeFi) protocols.
* **No-code configuration**. Vault owners can add custom integrations by configuring calldata constraints called hooks without the need to write any custom code.
* **Modularity**. Each Aera vault can upgrade parts of its functionality as its purpose evolves. This allows Aera to support adaptive strategies that take advantage of emerging market opportunities. For treasury managers, Aera can be tailored to offer the strongest possible protections for their assets.

#### Use Cases

* **Treasury Management**. Like V2, Aera V3 can be used to manage DAO treasuries without compromising on voter control or speed.
* **Yield**. Aera can be used to deploy purpose-built multi-depositor vaults to implement various DeFi yield-generating strategies or launch new reward programs.
