Paradym Wallet
The Paradym Wallet is an open source companion app to the Paradym platform available on the Apple App Store and Google Play Store . The Paradym wallet enables people to manage and present their digital credentials seamlessly. The credential data is stored locally on the user’s device, meaning that they retain full control over the information and decide who to share it with.
The Paradym Wallet is fully integrated with Paradym, and can be used as a holder wallet for issuing and verifying credentials to.
Consider an existing identity wallet first
The Paradym Wallet is a full-fledged holder wallet, but it is still a custom application your users have to discover, install, and trust. Before building on it, consider whether you can integrate with an existing identity wallet from an established identity ecosystem instead — often a government-backed EUDI Wallet such as France Identité. For most use cases this is the recommended starting point:
- Better adoption and less friction. Existing and emerging (commonly government-backed) wallets ship to large user bases and are increasingly something people already have on their phone. Reusing a wallet your users already trust removes the “install yet another app” hurdle and gives a more frictionless experience.
- Verify credentials already in the ecosystem. You can request and verify high-assurance credentials that are already issued into these wallets, such as the mDL and PID in EUDI wallets, without issuing anything yourself.
- Issue alongside government-issued attestations. For issuance, these wallets let you issue your own credentials right next to the government-issued attestations the user already holds, so your credential lives in the same wallet as their official identity documents.
See the supported wallets overview for the wallets and identity ecosystems Paradym integrates with out of the box. The Paradym Wallet remains a great fit when you want a wallet you fully control, to support credential formats or exchange protocols an existing wallet doesn’t, or to get started quickly without depending on an external ecosystem.
