Create a DID-Linked Resource

Create a DID-Linked Resource (DLR) on cheqd using the Credo Agent.

The createResource method from the Credo cheqd module allows you to create a DID-Linked Resource and publish it to the cheqd network under a did:cheqd identifier.

DID-Linked Resources are uniquely identified by a UUIDv4 resource ID and persistently attached to the DID on-chain. These resources can later be resolved by ID or query parameters (e.g., resourceName, resourceType).

Required Parameters

Field	Required	Description
did	✅	The did:cheqd identifier under which the resource is created
id	✅	A UUID string that acts as the permanent resource ID
name	✅	A human-readable resource name
resourceType	✅	A short type identifier (e.g. TrustRegistry, Logo, StatusList)
data	✅	The content to store (object, Base64-encoded string, or plain text)
version	❌	Optional semantic version string (e.g. "1.0")
alsoKnownAs	❌	Optional array of aliases for the resource

Example

await agent.modules.cheqd.createResource(
  'did:cheqd:testnet:92874297-d824-40ea-8ae5-364a1ec9237d',
  {
    id: '6de33634-6439-4e46-aa3f-bfe03606b000',
    name: 'exampleTrustRegistry',
    resourceType: 'TrustRegistry',
    version: '1.0',
    data: {
      name: 'Example Org',
      jurisdiction: 'EU',
    },
  }
)

💡 The id field must be a UUIDv4. You are responsible for generating and tracking this ID.

Recommendations

• Ensure the id is a UUIDv4, generated using a reliable UUID library (e.g., uuid in Node.js)

• Keep resourceName and resourceType descriptive but concise — they are used for resolution

• If the resource data is sensitive or large, consider encoding as a base64 string

• Use version to manage changes to the resource over time
