Service for managing and retrieving verifiable credentials from different sources. By default, it includes procedures for IPFS and Crossmint, but additional procedures can be added by the user.
- CredentialService().getById(credentialId: string) : Fetches the credential from crossmint using the credentialId.
- CredentialService().getCredential(collection: CredentialsCollection, tokenId: string) : Fetches the credential from the source that matches the storage location of the credential.
Remarks
To use the Crossmint procedure, a Crossmint API key with thecredentials.read scope must be set.
