Unparalleled ERC20 trading.


Beta Help & Feedback

Known issues (as of 1/15)

The Paradex beta is an insider's look and work in-progress that we're improving by the day. We'd love your overall impressions but want to stress that we are aware of some bugs. These are the major items and issues we're currently focused on improving in the coming days and weeks:

Balance updates 🐞

Balance updates aren't as speedy or responsive as we'd like them to be. This is an inherent problem with Ethereum dapps, and we'll be continually tweaking and iterating to find a sweet spot for these throughout the UI.

Order book & trade history quirks 🐞

We're seeing some occasional artifacts popping up in the order book and trade history that disappear on refresh. We'll be keeping a close eye on this to ensure that the order book and history widgets can be trusted 100%.

Charting and visualizations 🐞

We're working to fix and improve quirks with the existing charts and visuals, and plan on adding additional functionality to these widgets over time. If there's a specific visualization feature that you feel is important to you as a trader, send us a note!

General stability & reliability improvements

We won't be satisfied until we're the most reliable, responsive and performant decentralized exchange on the Ethereum blockchain. Finding stability improvements to our underlying stack will be a principal focus, from the beta period until well after we launch.

We'd love to hear from you! We're setting out to build Ethereum's best decentralized trading platform and hope to make that possible with your help.



Need help getting started?

We know Ethereum isn't the most user-friendly ecosystem, so we've put together a very basic guide to help you get trading on Paradex.


Signing in to Paradex

1. Make sure MetaMask is installed, running and unlocked, and that the correct network is selected (find it in the dropdown just to the right of the fox when you open MetaMask); if you're testing our Kovan testnet beta, select Kovan, otherwise make sure you're connected to Ethereum mainnet. Paradex will automatically see your wallet and show your address as an option in the "Select account" menu.

2. Click your address in that menu, which will bring up a confirmation window that contains both your address and a text input field for your invite code.

3. Paste in your invite code and click the 'Confirm' button to proceed. Click 'Sign' when MetaMask opens and prompts you to confirm. If the sign-in was successful, you'll be redirected from the alpha gateway to a market within the Paradex platform. If the sign-in wasn't successful, you'll be prompted to re-enter your code. If you keep getting rejected, let us know.

Note: you only need to enter your invite code the first time you connect your account. After your first successful sign-in, Paradex will recognize your address and will no longer require a code to access the platform.

Before you start trading

Unlocking your tokens

Once you have your tokens, you'll need to unlock them before you can trade. Token unlocking is what allows Ethereum to withdraw assets when an exchange is initiated. To unlock your balances for trading, visit your Account page and click the toggle next to the token you'd like to trade. If the toggle is green, that token is unlocked and tradable.

Wrapping and unwrapping Ether

Paradex works using something called the ERC20 token standard, which defines a set of rules that dictate how tokens on the Ethereum blockchain should work and function. Because tokens that comply with this standard all behave the same, it gives us predictable and sure-fire ways to interact with them programmatically.

A current quirk of Ether is that it isn't ERC20 compliant. In order for us to trade Ether on Paradex, we first have to temporarily convert it into an ERC20 token. This process is called wrapping, and wrapped (tradable) Ether is referred to throughout Paradex and the Ethereum ecosystem as WETH.

To wrap and unwrap your Ether, simply visit your account page and click the 'Wrap' and 'Unwrap' buttons in the balance table. Once your Ether is wrapped into WETH, you'll be able to use it to create orders in any of our WETH markets.
