$1,000 USD - Create a Decentralized Exchange
hashingsystems
JavaScript, HTML, CSS
### Create a DEX on Hedera Hashgraph
### Prize Bounty
$1,000 USD (in HBAR).
### Challenge Description
Decentralized exchanges provide a safe way to transfer assets in a distributed ledger. This challenge involves building a decentralized exchange as proof-of-concept on the Hedera Hashgraph network, and you’ll use [Console](http://console.hashingsystems.com/) to deploy the contract.
### Resources
This bounty is based on [Hedera Hashgraph](https://hedera.com) and uses the MetaMask-like extension [Composer](https://chrome.google.com/webstore/detail/composer-for-hedera-hashg/hdjnnemgikeoehneddegfcmkljenlean)
There is an [ERC20 hot wallet](http://myhbartokens.com/) example built on ReactJS that allows anyone to interact with an ERC20 contract on Hedera.
### Guidelines
Deposit tokens to the smart contract.
Show the balance for the current user.
The DEX should implement order matching logic that matches the orders and executes the exchange between the two tokens (ERC20, on Hedera).
Because it isn't possible to query orders for free, each order should have a query-able ID and page.
### Submission Requirements
Build a website that lets user deposit tokens to contract and provide a page that displays a single order based on an ID. Users should be able to exchange between ERC20 tokens (on Hedera).
Clone the (hbardelta repo)[https://github.com/hashingsystems/hbardelta] and work on it. Submit a PR when you're done working on this.
### Submission Deadline
11:59 pm Eastern on December 16th
### Judging Criteria
The prize will be awarded to the individual/team that produces the best approach and the most user-friendly submission while respecting the challenge description.
### Winner Announcement Date
December 17th
