How to Trade on Aster DEX Mobile – Step-by-Step Guide

It all began with a post from CZ on June 1, 2025, suggesting that the crypto market was ready for a dark pool-style perpetual DEX, one that could bring greater privacy and efficiency to derivatives trading. Just 18 days later, Aster DEX launched with stealth perpetual orders, aligning closely with that idea. Since then, the platform has gained recognition in the perpetual DEX space, recording over $90B in daily trading volume.

Beyond its web interface, it also gives Android users the ability to trade perpetuals directly through its mobile version. This guide explains how to set up and trade on Aster DEX mobile, covering everything from connecting your wallet to placing your first order.

Aster DEX Mobile Requirements

Before we get into the steps on how you can set up and get started with Aster DEX mobile, there are a few important things to point out:

1. Mobile Requirements:

This walkthrough uses Android. Aster also provides an iOS download; use the links on the official Aster website to choose your version. Read our full Aster DEX review
to learn more about Aster DEX and its features.

2. Web3 Wallet:

When trading on Aster DEX; whether through the web interface or the mobile app, you’ll need a Web3 wallet that is compatible with the networks supported by Aster DEX. Currently, Aster DEX mobile only supports BNB Chain, Ethereum, and Arbitrum.

To use Aster DEX, you’ll need a wallet that supports any of these networks. For this guide, we’ll be using MetaMask, as it supports the EVM networks used in this Android walkthrough.

3. Gas Fees:

While Aster DEX is generally quite affordable, to get started on the mobile app you’ll first need to transfer funds from one of the supported networks. Since this is an on-chain transaction, you’ll need to hold a small amount of the native token to pay for gas fees.

For example, if you decide to use the Binance Smart Chain, you’ll need to hold some BNB tokens to cover network gas costs, which usually range between $0.01 and $0.10.

Download and Set Up MetaMask (Web3 Wallet)

To begin, let’s download and set up your Web3 wallet. The process is simple and only takes a few minutes, so let’s get straight into it.
