DID

Manage DID operation using DID APIs
Please generate access token before proceeding. Once you generated the access_token, you can pass this token as bearer authorization token in the header for all APIs.
Note: Some of these APIs are on-chain APIs which means they need network fee to successfully execute, so make sure that your application wallet address has $hid tokens. Read network fee section for more details.
Entity Studio SSI API base URL: https://api.entity.hypersign.id​
There are 3 steps involved in DID creation:
  • Generate a DID Document: Generate the data structure of the DID document.
  • Sign a DID Document (optional): Sign the DID Document using verification method.
  • Register a DID Document (optional) : Registers the signed DID Document on the blockchain network.
Note: You can choose not to register a DID on blockchain, in that case, the DID is concidered as private DID. We support Ed25519VerificationKey2020 for private DIDs. Kindly read difference between private and public DID in this section.
