CiMPLE.cc (React + Meteor Devs)

Posted by CiMPLE

Required skills

The CiMPLE DAO is looking for contributors.
You can learn about what CiMPLE is here: http://CiMPLE.cc
In short, CiMPLE is a set ofstrategies and calculations that generally results in acquiring more tokens. This is done by borrowing against the tokens (when the price dips) to buy more and selling some when the price goes back up to pay down the debt and allow you to do it again on the next dip. There are also yield strategies made possible by flash loans, and insurance against liquidations from too much leverage. Finally, there are graphs to show the user how well these strategies have worked for them compared to just HODLing the tokens.
The application is built on Meteor with React as the MVC and D3.js for all the graphs.
The user's smart account is built on top of InstaDapp, so to complete any transaction, we're using their SDK.
In addition to the web application developers, we're looking for someone to make tweaks to the react code to make it compatible with react native & build an application that more/less functions as the metamask wallet on browser mode viewing the web app, including a wallet to sign transactions and a link between their mobile and web app so they can sign transactions from both devices while retaining separate wallets to sign.
LaborX requires us to put a budget, this is for on-going contributions, please submit your competitive monthly salary request and hours of availability in your application.
