Cardano-based Marketplace

What is the Marketplace?

The marketplace is an all-in-one solution for the decentralized trading of user-made tokens. It serves as an easy entry for beginning NFT users, providing a platform for a low-floor-high-ceiling NFT market, and creates a home for advanced users due to the simplicity of design combined with the great flexibility and customization the marketplace brings to the industry.

A marketplace without gatekeeping.

Any user may register a token with the marketplace and can start trading their token immediately. This opens a new pathway for selling tokenized objects on the internet. In theory, this means art, tickets, houses, cars, anything tokenizable, could be traded in a decentralized way without a controlling party. This is huge and makes this marketplace more than just a simple token swap.

General Use

Users will link their wallets to the marketplace allowing them to create and complete orders on the blockchain. If a user mints a token, they can add the token to the marketplace.

Goals and Deliverables

------------------------------------------------------------------------------------------------

ReactJS single page application for the marketplace

• Fully-functional minus non-existent technology

1. Smart Contracts
2. Wallet Linking

• Incrementally improve on UX with each iteration

1. Mockup > Alpha > Beta > Release

Open Sourced Cardano ReactJS Components

• Allow a user to display token information in a beautiful and informative way.

1. An artist can use it to display an NFT in their portfolio.
2. eCommerce can use it to display tokenized goods.

• Allow a user to create and/or complete an order.

1. Generalize the component enough for arbitrary market creation.

Marlowe and Plutus Smart Contract Modelling

• Use Marlowe and Plutus to create the smart contracts that will run the marketplace.

1. Preferred Haskell only implementation.

Marketplace RESTful API.

• Publically available API for the marketplace.

------------------------------------------------------------------------------------------------

Milestones

------------------------------------------------------------------------------------------------

Create www.logicalmechanism.io for stake pool splash page and app hosting.

• Use Django for backend
• Use ReactJS for frontend
• Use Postgres for database
• Potential: run a passive relay node and db-sync

1. Custom token verification without third-party API.

Build ReactJS single page application for the marketplace.

• Users can add tokens
• Users can create new orders
• Users can complete existing orders.
• Users can view detailed information about the tokens in the order.
• Users can link their web wallets.
• Users can search and filter results.
• Potential: Users can view current market prices for popular tokens.

Build Backend API for single

• Create URL endpoints for each component in the SPA.
• Create custom validation functions for custom forms.
• Create custom DB functions for maintenance.
• Create DB models.

Model Smart Contracts in Marlowe and Plutus

• Use the playground to plan each smart contract required to run the marketplace.

1. Try to use Haskell as much as possible for maximum flexibility.

Open-source the contracts for public knowledge and trust.

Why A Prototype?

The marketplace requires a lot of development that isn't web-related. The entire marketplace relies on a web3-style wallet integration and random peer-to-peer smart contract execution. Both of which do not exist at this time.

------------------------------------------------------------------------------------------------

Funding

------------------------------------------------------------------------------------------------

Hire React developer for 40 work hours a week for a single month.

• The low-end is about 3500.
• The high-end is about 16000.
  I am asking for 5000.
  I estimate the required development time to be approximately one month. All or most of the project goals will be completed within this time frame.
