Introducing the WandX Beta — trading a portfolio of ERC20 Tokens through smart contracts

We’re glad to announce that the WandX Beta 1.0 is up on the Ethereum Ropsten Testnet. This allows users to create and trade a portfolio of ERC20 Tokens with Testnet Ether.

Video guide to use the WandX prototype.

Prototype user guide

1. You must have the Metamask chrome extension installed, and connected to the Ropsten Testnet.
2. You must have Ropsten Testnet Ether in your account. If you don’t, you can visit https://faucet.metamask.io to get test Ether.
3. Once you have The Testnet Ether, you can go to http://wandx.co/app. This is the Dapp.
4. The Address is directly picked up from Metamask. Enter your name, and optionally enter your email.
5. Enter the name of the coin in the exact syntax as given below in the table. Eg: Enter ZRX, and type “Get Coin”.
6. Confirm the transaction on Metamask, and the coin contract will send across the coins to your Metamask address.
7. Once you’ve got the coins, you can go to the Portfolio tab and create your own baskets of Tokens.

Portfolio creation and trade

The coins that you got from the Get Coin API can be used here to create a portfolio. You will have to list out a price for the portfolio in Wand after creation.

Sell

1. You will be able to view the portfolios that you own in this section.

Buy

1. Other users will be able to view the portfolio that you created.
2. You will be able to see the portfolios that others have created, quote a price for it, and buy it.

On-chain

All transactions that happen on-chain are through the smart contracts that we’ve created. These smart contracts can be called through our APIs.

Creating portfolios — creation of portfolios by users is done through the API.

Buy/sell portfolios — Accepting Bid and Ask prices calls functions from the API which execute the smart contract code.

Off-chain

Order book listing — Listing the portfolios available to buy/sell will be done off-chain. Keeping the list on-chain would be very expensive because of gas costs due to change in contract state.
