# Technical Overview

#### System Architecture

Brava is a non-custodial DeFi automation platform built on Safe smart accounts. The architecture consists of two main layers:

#### Smart Contracts (On-Chain)

The on-chain layer provides secure, deterministic execution of DeFi strategies:

* **Safe Accounts:** User-controlled smart contract wallets maintaining full custody
* **Action Contracts:** Modular protocol adapters (Aave, Yearn, Morpho, etc.)
* **SequenceExecutor:** Orchestrates atomic multi-action transactions
* **AdminVault:** Governance and configuration registry with time-delayed proposals
* **EIP712 Module:** Cross-chain bundle execution with single-signature authorization
* **BravaGuard:** Transaction validation ensuring funds stay within approved protocols

#### Data Intelligence Layer (Off-Chain)

The off-chain layer handles computation, orchestration, and user experience:

* **Pool Discovery & Onboarding:** Automated protocol integration and vetting
* **Risk Intelligence:** Real-time monitoring and assessment of protocol health
* **APY Analytics:** Continuous yield calculation and performance tracking
* **Transaction Orchestration:** Cross-chain execution coordination and monitoring
* **Data Indexing:** On-chain event tracking and historical data aggregation
* **User Interface:** Portfolio management and strategy execution dashboard

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.brava.finance/technical/technical-architecture/technical-overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
