Verida Dapp connector

This application directs a user to generate a zero knowledge proof (using zkPass or Reclaim protocol) of something on an external website. This proof is then sent to the user’s Verida Wallet using the Verida inbox messaging system.

Usecase Examples

• Verify if you exceed trading volume on Binance
• Verify if you are discord owner
• Verify if you have Uber account
• Verify credentials from zkPass and Reclaim protocol

Setup

Setup zkPass account

• Follow this instructions
• Create new application and register necessary schemas .
• Get APP_ID
• In src/config/providers.ts update schemas with your own schemas.
• Update NEXT_PUBLIC_ZKPASS_APP_ID in .env file.

Setup Reclaim account

• Go to https://dev.reclaimprotocol.org/dashboard
• Create new app and register necessary providers
• In src/config/providers.ts update provider data with your own providers.
• Update NEXT_PUBLIC_RECLAIM_APP_ID in .env file
• Update RECLAIM_SECRET_KEY in .env file

Add PRIVATE_KEY to send message through Verida messaging system

• Update PRIVATE_KEY in .env file.

Add VERIDA_SEED to send message through Verida messaging system. You get this from Verida Wallet.

• Update VERIDA_SEED in .env file

Run

yarn install
yarn build
yarn start

• http://localhost:3000/add-credential?schemaId=[schemaId]&veridaDid=[veridaDid]

• http://localhost:3000/add-credential?veridaDid=[veridaDid]

## Verify credentials from zkPass and reclaim protocol.
- Open `http://localhost:3000/verify
- Connect to your verida wallet
- Click `Request credential`

### How it works?
The system initiates a data request to the connected wallet's inbox. Upon the user providing their credentials, the backend system proceeds to authenticate the validity of the credentials, based on the credential types such as zkPass or reclaim.


## Deployment

We deploy using AWS Amplify. Make sure all env variables are set in the Amplify console and added into amplify.yml for serverside rendering.

Eg:

  commands:
    - env | grep -e NEXT_PUBLIC_ZKPASS_APP_ID -e PRIVATE_KEY -e NEXT_PUBLIC_RECLAIM_APP_ID -e RECLAIM_SECRET_KEY -e VERIDA_SEED >> .env
