GitCoin Bounty: Develop a simple DEX in Plutus language for Cardano

[EtherDotBlue]

Description:
This task is to build a simple POC level DEX using the Plutus language created by Cardano-IOHK. The developer ideally will have experience with Haskell and a history of work or an active interest in developing Decentralized Applications for Blockchains.

Create a full POC that allows users to swap between supported tokens within one smart contract method call. Users can also contribute to liquidity pools for any supported token, and therefore gain commissions in the form of exchange fees for doing so.

In addition to the smart contract, the developer should include notes documenting the experience in detail and providing that feedback and recommendations to the Cardano-IOHK team. This is important!

Note: This project must be completed before April 5th.

I have been learning haskell the last few days and i'm confident I can take on this issue. Will develop the app with plutus in the next few days and document the whole process. Should be done by Wednesday next week.

Learn more on the Gitcoin Issue Details page.

[mul1sh]

Almost done, just testing thee flow of the dApp right now :)

[EtherDotBlue]

@mul1sh Let me know when I can have our team take a look.

[mul1sh]

@EtherDotBlue Apologies for the long delay in this, working in haskell/plutus is a bit harder than I anticipated. Even when I think i'm nearly done, I still get bugs which end up taking alot of time to fix because I have to keep referring to the tutorials to find workarounds.

In light of this I wanted to kindly request you give me an extension till this Friday to get it done. I'm sure i'll have it working then, if its not possible, then no worries I highly appreciate the opportunity.

[EtherDotBlue]

@mul1sh Yes, that is fine. We are also very interested in your overall experience, and what was harder than expected! Tom

[mul1sh]

I think i've finally fixed all the bugs I was getting, just doing the final test now and also wrapping up on the writeup and I submit in a few hours.

[EtherDotBlue]

OK, let me know when our devs can take a look!

@gitcoinbot I'm redoing my approach to this task by implementing a bonding curve/automated market maker. The initial approach I was using for order books didn't work so well for liquidity pools.

Still working working on the staking part.

[EtherDotBlue]

OK! Let me know how it goes. The guys from Cardano are eager to see what you have created. And it is OK if you are not 100% done.
