Functionality

The Wallet Kit makes it easy for you to build and launch your own wallet. Now, you can think of wallets as secure data hub for organizations and individuals which allows them to act as "Holders", i.e. they can store, manage and share keys, identity data (e.g. Verifiable Credentials) and other secrets.

Practically speaking, a wallet is a tool that allows anyone to collect and present identity data in order to access services (e.g. sign up, login, check-out) or procure products in a seamless and privacy preserving fashion.

Since there are different types of wallets, it is important to mention that our Wallet Kit enables so-called custodial wallets, which means that keys and data are ultimately stored by the wallet provider (e.g. by you). While this means less control for end-users, it also means a better user experience (e.g. no need to handle private keys or seed phrases) and less risk (e.g. loss of data). Also, end-users enjoy full data portability, which means that they can switch wallets (and take their keys and data with them) at any time without having to fear lock-in effects.
