TEZOS4EUDIW is a web application that allows users to prove ownership of a crypto wallet and receive a verifiable credential representing that ownership in their EUDI wallet.
The application enables the issuance of a Proof of Crypto Ownership credential bound to a Tezos wallet address, using the OpenID for Verifiable Credential Issuance (OIDC4VCI) standard.
TEZOS4EUDIW provides the following functionality:
- Connects to a user's Tezos crypto wallet using Beacon
- Requests the user to sign a message to prove control of their wallet address
- Verifies the signature server-side
- Issues a verifiable credential attesting wallet ownership
- Delivers the credential to the user's EUDI wallet via QR code
- Notifies the web application when credential issuance is complete
The issued credential can then be used as a trusted proof that the user controls a specific crypto address.
- Proof of crypto wallet ownership without transactions
- Issuance of SD-JWT Verifiable Credentials
