Issue credentials on the Sovrin Network!

Businesses, governments and other organizations with Sovrin-based use cases currently in development may now write to the Sovrin Public Ledger and begin issuing as many self-sovereign identity credentials as they desire. Simply use the webform below to begin the process of becoming a Sovrin Transaction Endorser. The Sovrin Foundation charges a small fee (see table below) for writing to the public ledger but does not charge for the act of issuing a credential– issuing credentials on Sovrin is FREE.

Wondering what to write?

Public DIDs are needed first and foremost by issuers of credentials. They are stored on the Sovrin Public Ledger so that a verifier who receives proof of any credentials is able to look up the public key of the issuer in order to validate the proof.

Fees Explained

  • A credential issuer may only need to write a few things to the Sovrin Public Ledger to issue millions of credentials. Learn more about What Goes On the Ledger.
