Learner Credential Wallet is a cross-platform iOS and Android mobile application for storing and sharing digital learner credentials.
Install Learner Credential Wallet for your mobile!
The wallet is based on the learner credential wallet specification developed by the Digital Credentials Consortium. The learner credential wallet specification is based on the draft W3C Universal Wallet interoperability specification and the draft W3C Verifiable Credentials data model.
The app has been compiled for iOS and Android and allows users to add and share credentials, as well as manage the wallet.
This learner credential wallet includes the features and technical requirements ultimately enabling individuals to curate and present their learning and employment records to others—for example, as applicants to educational programs or to apply for jobs with employers—in an interoperable manner.
- Receive digital credentials from standards compliant issuers via link or QR code
- Store credentials on their mobile device
- Keep credential access safe with strong encryption best practices
- Create and share a presentation that collates any number of credentials in their wallet
- Backup and restore their wallet
The Digital Credentials Consortium is working with a number of colleges and universities to pilot test the wallet.

Prerequisites:
See Installing on Linux on setting up the project on Linux.
- Clone this repository or
git pull - In root of project, run
npm i --legacy-peer-depsto install the React Native dependencies.- Note: The app will crash if you try to use just
npm ioryarnfor example - (Optionally, if you use the
asdfversion manager runasdf installto install - more info in asdf section below)
- Note: The app will crash if you try to use just
- Run
npm run prebuild:iosandnpm run prebuild:androidto set up theiosandandroidfolders. This step uses Expo prebuild.
- Run
asdf installto install the proper versions of the technologies used listed in the.tool-versionsfile- If you need to install anything, run
asdf plugin add [plugin-name]to add it to your local machine - Here is a link if you need it to the asdf installation documentation (homebrew is the easiest)
- If you need to install anything, run
- Run
yarn startin one terminal - In another terminal run
yarn android
- When running on android, open Android Studio and make sure the device you want to run on is selected (whether that is an emulator or a real device).
- Note: You might need to hit the play button in Android Studio for it to fully register which device to set to be used from the command line.
- In another terminal yarn
yarn ios
This project uses TypeScript and React Native with Expo. It would be best to use an
editor that can hook into the TypeScript language server (VSCode does this with
Intellisense, Vim does it with CoC). We also use eslint to catch common mistakes
and formatting errors. Most editors should support dynamic linting support while
editing. If your editor does not, you can manually lint by running npm run lint
in the project root.
This project also uses environment variables, which are stored in config.ts.
These values can be overridden, but development values should not be committed to the repository.

Overridable configuration lives in two places:
app.json- created by Expo, contains app name, icon, splash page color, etc.app/config/index.ts- contains everything else, including a list of Known DID Registries, deep link schemes, app website URLs, and so on.
Instructions for issuing a credential.
A custom display can be created for different credentials, to do so:
- Create a new React component for your credential type in
app/components/CredentialCard/ -
eg.
app/components/CredentialCard/YourNewTypeCard.tsx - Define addition styles in
app/components/CredentialCard/YourNewTypeCard.styles.tsx - Add a function to the
credentialTypeslist defined in app/components/CredentialCard/CredentialCard.tsx. The function should return{component: YourNewCredentialCard, title: 'the title of the credential that should be used when listing it elsewhere'}or null if the credential isn't the appropriate type for you custom display - note: the list will be scanned for the first function that returns a component and title, so it's important that the type check is specific and doesn't match any other types.
