# 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:

<table><thead><tr><th width="217">Product / Component</th><th width="345">What it is</th><th>Who it is for</th></tr></thead><tbody><tr><td><strong>VOOI Ultra app</strong></td><td>Unified trading app across supported perp DEXs</td><td>Traders</td></tr><tr><td><strong>VOOI Perps API</strong></td><td>One API for interacting with supported perp venues</td><td>Builders and integrations</td></tr><tr><td><strong>VOOI MCP</strong></td><td>MCP server for AI agents and agentic workflows</td><td>Strategists and AI agents</td></tr><tr><td><strong>VOOI Ultra Tools</strong></td><td>Market data and workflow tools for margin transfers, venue comparison, funding rates, and funding arbitrage</td><td>Traders, strategists, and agents</td></tr></tbody></table>

Traders use **VOOI Ultra** app to trade across supported venues from one interface. They can also use **VOOI Ultra Tools** to analyze markets, compare execution conditions, open positions, and manage capital across venues.

***

Builders use **VOOI Perps API** to add perpetual trading to their products without integrating each venue separately.

***

Strategists and agents use **VOOI Ultra Tools**, and **VOOI MCP** to automate funding arbitrage and other cross-venue workflows.

### Supported Venues and Markets

Supported venues and market groups currently include:&#x20;

* Extended
* Hyperliquid
* trade.xyz (HIP-3 market group on Hyperliquid)
* Kinetiq (HIP-3 market group on Hyperliquid)
* Lighter
* Aster

Supported venues, markets, and features may change over time.

### 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.
