Smart Contract Development (ERC721) & API & Development of a Native Real Estate Dapp (Decentralized App)
$1500-3000 USD
Paid on delivery
We need a smart contract developed with the ERC721 token. An API or SDK will need to be developed as well to communicate with the smart contract to develop our Real Estate Dapp.
See below for the Dapp functionality for our MVP. This could be a long term engagement for our full Dapp, if the MVP developed is up to our standard.
*1.* Information Architecture - create a database that houses the UUIDs & Passwords and any other verifications needed to link to their Chelle Wallet where the ERC-20 tokens that were purchased from our ICO cabinet (for MVP). The database must be able to migrate new columns and/or rows as we scale the app up in Phase 2 where users will be able to convert fiat currencies and other cryptocurrencies like Bitcoin. The database must also keep information about properties that we have purchased (total amount that can be invested), and keep information on how much was invested by each user, and a schema developed per property that holds information specific to said property (sq footage, rooms, floors, pets allowed, security, location etc),. Properties will be added consistently, and the information architecture must be easily updated.
*2.* We need further information/consultation, but another smart contract might need to be developed that handles the logic associated with the creation of the ERC 721 tokens once a user invests in one of our property listings (for MVP). This must be able to scale up in Phase 2 of our app where users will receive monthly returns (dividends) based off the allotted percentage they have invested in each property.
*3.* The back-end logic must communicate with the smart contract(s). Display a users Total Token Balance, how many Invested Tokens and in which specific properties, and tokens left for investing. This must be able to scale for buying/selling properties as well as receive monthly dividends in Phase 2. This might be done with an API to crypto wallet agency.
*4.* Each listed property must have a total amount of investment opportunity. This can be shown with a progress bar, and must pull information from the database on how much has been invested by all users on each property listed.
*5.* Users must be able to scroll through our property listings, where they can click on a specific property that leads to another page. This page will contain more details regarding the property: sq footage, rooms, floors, pets allowed, security, location (google maps API), brief description etc.
*6.* If a user chooses to allocate their ERC 20 tokens, the back-end must communicate with the smart contract to issue ERC 721 to users which will be represented as an investment allocation on said property. This will update the users Chelle Wallet, and the users property portfolio
*7.* A portfolio page must be created that shows all the properties a user as invested in and how many tokens were allocated in each.
*8.* A wallet tab that shows users their Chelle token balance and Chelle Token value. The portfolio page can be apart of this.
*Strategic Planning to Oversee:*
- User's story
- How this person/agency will define the infrastructure requirements and scaling techniques
- how this person/agency defines smart contract integration logic with ethereum blockchain
- sending transactions to Blockchain/mainnet/sidechain
- tracking transactions/balance changes, block changes etc
- back-end integration with smart contract.
*Back-end:* Nodejs/Python/Ruby on Rails?
*Front-end* must be a native app for both IOS and andriod (Reactjs).
