I need to develop a prototype of app for the provenance and authentication of Luxury goods.

The project is similar to these projects:

[login to view URL]

[login to view URL]

[login to view URL]

[login to view URL]

We need to be able to scan an NFC chip and know if the product is genuine or not, with product information attached.

Mission

I have started to develop an app (Mostly UI) and will give access to the repo.

[Pictures attached]

I need someone to:

Finish the integration of the wallet (fix my integration)

Add support for ERC 721 (Non fungible token) to the wallet

Create the smart contracts

Setup a testnet (Ideally Quorum [login to view URL])

The app should be able to do the basic functions :

- NFC scanning and reading

- possibility of reporting a lost item and awarding a reward for finding it

- possibility of reporting in the event of theft

- sending and receiving certificates of authenticity for the purposes of purchase

- possibility for smart contract management

- integrated wallet multi currencies

- possibility to import other cryptocurrency wallets

Librairies

Librairies I used:

For the wallet: [login to view URL]

For NFC reading: [login to view URL]
