# Ultra Tools

## Overview

VOOI Ultra provides a set of tools for traders who work across multiple perpetual DEX venues.

These tools help users compare venues, review funding differences, prepare cross-venue strategies, and move free margin between supported venue accounts from one interface.

Each tool has its own dedicated documentation page. This page gives a high-level overview of the VOOI Ultra toolset and explains how the tools relate to each other.

## Available tools

VOOI Ultra includes the following tools:

* Transfer Margin
* VOOI Perps Arena
* VOOI Arbitrage Desk

### Transfer Margin

Transfer Margin allows users to move free margin between supported venue accounts directly from VOOI Ultra.

Use it when you need to rebalance collateral across venues without withdrawing funds to a wallet and depositing them again manually.

### VOOI Perps Arena

VOOI Perps Arena allows users to compare execution costs across supported perpetual DEX venues before opening a position.

Use it when you want to choose where to open a position based on the selected trading pair, direction, size, and leverage.

### VOOI Arbitrage Desk

VOOI Arbitrage Desk helps users find and prepare potential paired long and short setups across supported venues.

It findes possible cross-venue setups for a selected asset. It also provides current market data and historical spread charts, helping traders evaluate whether a funding or price difference is temporary or has persisted over time.

### Authorization model

Some VOOI Ultra tools can be viewed without authorization.

Authorization is required when the user proceeds to an action that affects their account, such as opening a position, opening a strategy, or transferring margin.

## How the tools work together

The VOOI Ultra tools support different parts of a cross-venue trading workflow.

* **Perps Arena** helps users compare execution costs before opening a position.
* **Arbitrage Desk** helps users evaluate and prepare paired strategies based on funding rate differences.
* **Transfer Margin** helps users rebalance free margin between supported venue accounts.

Together, these tools help users review opportunities, compare venues, prepare trades, and manage capital across supported perpetual DEXs from one interface.
