Discord research

Posted by Anonymous

Required skills

Hi I am looking for some longer term brain power for me. I need persons to run couple accounts on discord for me. My business is about NFT industry(digital art and collectibles in cryptocurrency). Im early adopter of new NFT spaces. There is no need for you to know anything about the matter. At the moment this space is really demanding in case of attention span of members on discord rooms and channels. Im lacking of time as an investor already but aware of the big potential. That is why I am looking for people to run multiple accounts (in different web browsers or desktops) to gain access to different rooms. You would also be elligible to the knowledge gained there and in that case you could make significant gains apart from the salary which I can provide. I am willing to pay for 2-4 hours a day in the beginning. Also I would be very helpful if there was any misunderstanding, confusion or any knowledge you would like to gain regarding NFTs. I am trying to make a team of professionals here, so its fine for me if somebody is learning. Please let me know whats your take on that
Budgt above is monthly payment(for beginning)

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.
