# Ultra Overview

## **Overview**

VOOI is a unified perpetual execution layer for trading across multiple perpetual DEX venues.

VOOI standardizes interaction with supported venues while keeping execution venue-native and non-custodial. Each venue keeps its own order books, liquidity, margin accounts, and execution logic. VOOI provides a unified way for traders, builders, strategists, and agents to work across them.

## Use Cases

VOOI can be used through several products and components:

### Execution Model

VOOI Ultra does not custody user funds and does not replace venue trading engines.

Each supported venue:

* Maintains its own order book
* Holds user margin and positions
* Executes orders natively
* Applies its own venue-specific rules, fees, and risk logic

VOOI acts as a non-custodial execution and coordination layer. It standardizes access to supported venues and provides tools for trading, margin coordination, monitoring, API-based automation, and MCP-enabled workflows.
