SSI Wallet by Datarella

The SSI Wallet by Datarella is a Self-Sovereign Identity solution launched in June 2021 that implements key digital identity standards and protocols. The wallet is built on the Aries Framework Go and supports multiple DID methods including did:peer for private connections and did:web or DIF's Sidetree protocol for public identity verification. It features selective disclosure capabilities through BBS+ signatures and integrates with the eIDAS framework for EU-compliant identity verification.

From a technical perspective, the wallet enables users to interact with SSI-compatible websites and IoT edge devices while maintaining privacy through its native support for pairwise pseudonymous DIDs that prevent correlation between different interactions. A key feature is the SDKR (Secure Decentralized Key Recovery) mechanism that allows users to backup and recover their private keys using only their official EU electronic ID, leveraging StorJ for decentralized storage. The solution can be deployed either in a fully peer-to-peer mode without a ledger or using public DID methods depending on the use case requirements.

The project has received funding through the European Commission's Horizon 2020 research program (Project No. 824509) under the Block.IS initiative. It is being integrated into several Gaia-X projects including collaborations with major industrial partners like Bosch, Airbus, and Continental. The wallet's focus on EU standards compliance and integration with official electronic ID systems positions it as a bridge between traditional identity infrastructure and decentralized identity solutions.
