Technology Improvements

General: Significant improvements and stability updates to our back and frontend have been made. API Standard: We are working to follow existing Øx API standards and have begun to assist in developing additional improvements (https://github.com/0xProject/standard-relayer-api). Ethereum Node: Improvements to our backend Ethereum node architecture for reliability. Websocket: Improved websocket event architecture for improved UX. Deployment Architecture: Improved deployment architecture to move features through staging environments before hitting production.

Future Features

We will continue adding new features in future development cycles. If there is something you would like to see on Radar, please let us know by joining our Slack. Right now, here’s the features we have heard the most, or have decided are most important:

Chart Improvements such as additional charts and chart information

Additional order pruning

API

Partnership integrations

Mainnet Launch Info

The next development cycle for Radar Relay will focus on two things. First, heavy testing of this update internally on mainnet and publicly on Kovan. Second, moving to mainnet once we feel comfortable with the amount of testing that’s been done both internally and by the community.

Help us Test

Head over to the newly updated app at https://app.radarrelay.com/. We ask that as you test, you do a few simple things:

Try to document any bugs, errors, etc as well as you can, include the steps you took to get them and any other relevant information. Try to place orders that are “accurate”, make sure that orders you place are close to the rates currently on the book and are similar to an order you would place if this was on mainnet. Be honest, if anything doesn’t make sense or seems wrong don’t be afraid to let us know.

Post any bugs, error, or feedback to the beta channel in our slack or submit them to this form.

User Flow

This update brings new ways of using Radar Relay. Below are steps to use Radar Relay.

Make sure you are on the Kovan test network

In MetaMask, select the icon to the right of the fox. Select Kovan Test Network from the dropdown.

Get test tokens from the Øx portal

Go to https://0xproject.com/portal/balances. “Request” ETH. Press the + icon, select the tokens you want to test with and request them.

Explanations

“I Have” is the token you are holding and looking to trade for another token (Token A).

“I Want” is the token you wish to receive (Token B).

“At a Rate of” is the the amount of Token B you would receive for each Token A.

How to allow tokens for trading

Why do I need to do this?

Open the Radar wallet. Go to “Your Tokens.” Activate the toggle to the green position for tokens you’d like to trade with.

How to wrap ETH

Why do I need to do this?

Open the Radar Wallet. In the “Your Tokens” tab there will be a WETH token. Make sure it is allowed. Click “Wrap” to convert some ETH to WETH. If you are worried about the cost you can lower the “Gas Price” in MetaMask, the lower you go the longer the transaction will take. When you are ready to get your ETH back click the “Unwrap” button. The same gas principles from above apply.

How to place an order

There are three ways to place an order on Radar:

Rate Based Order

Choose both the token you have and the token you want. Input the rate you want and lock it. Input either the amount of tokens you want or the tokens you have and Radar will auto-calculate the other input. Confirm everything is correct and select “Create Order”. Choose order duration. Sign your order in MetaMask or Parity. Select close or view order.

Token Based Order

Select the token you have and how much of it you want to trade. Select the token you want and how much you would like to receive. Verify the auto-calculated rate is correct by comparing the base currency amounts or the current rate on the book. Choose order duration. Sign your order in MetaMask or Parity. Select close or view order.

Order book based order

Select the token you have and how much of it you want to trade then select the token you want. Select an order off the bottom half of the order book. This will set the rate to the rate of that order and auto-calculate the “I Want” input. Confirm everything is correct and select “Create Order”. Choose order duration. Sign your order in MetaMask or Parity. Select close or view order.

How to fill an order

Select the token you have and the token you want. Choose an order off the top half of the order book to lock in the token rate. Input either how much you want or how much you have and Radar will autofill the other side. Continue through MetaMask or Parity to fill the order.
