Hello, I would like to submit dReams for the On-Chain Options and Futures category. Currently dReams is set up to run 8 different binary based P2P futures.






  • DERO-Difficulty

  • DERO-Block Time

  • DERO-Block Number

Contracts are flexible and can be used for different time limits and amounts. Price data is retrieved by the client from three sources and on chain data is retrieved from the agreed upon node. As well as participating in futures, users have the ability to install and run their own contracts, defining their own time limits and amounts. There is a leader board that can be used to keep tally of correct guesses for communal or competitive usages. With Gnomon index, contracts can be publicly indexed for all app users to participate in, or they can remain off the index for a more private setting.


This submission is for the NFA category. Azylem, DeathByCupcake and SixofClubs would like to submit our dReams NFA Colab.

125 individual NFA’s have been minted, all of which are in use as in game items in dReams and could be used by any other dApp that chooses to support them. The 7 collections (AZYDS, AZYPC, AZYPCB, DBC, SIXPC, SIXPCB, SIXART) are comprised of over 2000 individually crafted images, each one uniquely done and reflecting the artist’s style.

In dReams we’ve showcased their use as avatars, app themes and decks of playing cards that owners can share with other players at the table. Some of the assets serve two uses, for example owners of the AZYDS and SIXART assets can use them as either themes or avatars, making use of the main file and icon images.

To add further versatility, all ART-NFA-MS1 functions are leveraged in dReams and a fully functioning in game marketplace (powered by Gnomon) has been created, which allows users to claim, list and buy or bid on any of these assets directly in the app.

The asset can be viewed here.


This submission is for the Education and Development Tools → Visual Scripting category.

This web application lets you create Smart Contracts on DERO using a graph.
You can see the code being generated in real time!
It is supposed to work standalone and uses the browser’s local storage to keep edits between sessions.
You can also export and import projects (partial import supported, partial export planned).
A gallery should provide simple examples made by the myself or community.
A test environment based on the simulator running locally, connected via rpc bridge extension is planned.

The detailed roadmap is described in the README.

Very good luck to all !


This submission is for DeFi.

The $DTT DEX was designed to be the Uniswap of DERO with a permissionless listing feature.

The Ethereum-DERO bridge can accommodate any ERC-20 token and the wrapped token can be permissionlessly listed on the $DTT DEX.

The bridge has already had an audit that came back nearly flawless but finishing the front-end of the $DTT DEX has been more difficult than expected.


Submitting my BBS system for phase 1 dARCH, the DERO Bullish’n’Bored system. It is my first-ever Golang project, I’ve been sponging my way up the learning curve, please be kind. It is submitted as a proof-of-concept, still has some ways to go, will be happy to receive input and collaborate on continuing to make it awesome!

Much love to the whole DERO community, let’s rock this mutha!


Submission for dARCH Contest:

Name of Category: NFA

Name of Entry: DerBNB

Link to Github Repository: GitHub - apollo5ever/DerBNB: Rental Property Management built on Dero

DerBNB is a decentralized Airbnb built on the Dero blockchain. NFAs represent ownership of properties and a smart contract is used to manage all rentals. This project was completed by me and some students taking my course, Dero Dev 101, as a group project. The prototype has a basic UI that allows users to browse and request rentals, and as a property owner, you can view and manage rental requests. DerBNB also has a built-in private messaging feature, utilizing the private messaging capabilities of the Dero platform.


I would like to submit The BlackSwans Of Derogeddon for the NFT portion of dARCH.

Blackswans focus is premium visual content to raise the bar of quality In the Dero NFT marketplace.

Attracting new people to the space, specifically other artists through meticulously handcrafted layers, 3d rendered assets, proceedural fx, all seamlessly blended in photoshop with three ultimate goals:
maximum variety
maximum cohesion
and maximum professional finish.

Over 32 Swan bases, given 40 custom backgrounds, dozens hand drawn traits, And procedural filters ensure ensure that every user can have something truly unique.

Purchasing swans directly helps fund my other Dero marketing endeavors including Ads, info graphics, and promotional motion video which I have provided freely for all.

Swans are esthetically centered and meant to be viewed as art.
However, I do plan to also have special promotional Swan sellings to on board musical artists Into the dero marketplace.

I also promise to award anyone who on board’s successfully an outside artist to create their own NFt’s A special Swan. The caveat is that the artist has to wow me with skill, swans have a commitment to encouraging professionalism and high effort in the the Dero ecosystem.

This is the implementation of the ledger support. The current status is that I am still implementing bn256 using the SDK libraries. Once it is properly incorporated, the rest of the development will be faster.

The final goal is to have the Ledger App published in the App Catalog.
