How can we generate a SDR on-behalf of issuer

Hi Team,

While handling a scenario, where user is scanning a QR code which is seeking attestation from a issuer but as user does not have attestations yet from that issuer and could not able to share the credentials.

But by this time, We already have information about

1. Requested Attester DID
2. Claim type which were requested

So based on that data, I was trying to generate a SDR on-behalf of issuer and directly sharing the self signed credentials against the generated SDR to Issuer for attestation instead of asking user to go to attester/issuer portal and scan the QR code.

But while generating the SDR on behalf I’m getting a error

Error: the string “No identity: did:ethr:rinkeby:0xe000315b4fd38b0291c0b65c69b86f805fdab09e” was thrown

did:ethr:rinkeby:0xe000315b4fd38b0291c0b65c69b86f805fdab09e is the DID of issuer which was captured from the SP SDR.

code block used

  const jwt = await agent.handleAction({
    type: SD.ActionTypes.signSdr,
    did: signerDid,
    data: sdrInput,
    save: true,
  } as SD.ActionSignSdr);

Could you kindly suggest if there is a way to Generate SDR on behalf

Yes, Both VP and SDR are message types and can be created independently and sent anywhere. You can create arbitrary VP messages for example as a QR code so anyone can scan it.

You can however optionally provide a threadId in your SDR so when you send the VP response you can pass that id along so your database can tie responses to requests.

So to Draw a conclusion from above

• When any one is creating a SDR that time requestor signs using his keys
• We can create a VP and Share it with a DID (requestor) without a SDR request
