Driver Environment Variables

The driver recognizes the following environment variables:

• uniresolver_driver_did_indy_libIndyPath: The path to the Indy SDK library.
• uniresolver_driver_did_indy_openParallel: Whether to open Indy pools in parallel threads. This speeds up startup, but may consume more memory.
• uniresolver_driver_did_indy_poolConfigs: A semi-colon-separated list of Indy network names and pool configuration files.
• uniresolver_driver_did_indy_poolVersions: A semi-colon-separated list of Indy network names and pool protocol versions.
• uniresolver_driver_did_indy_walletNames: A semi-colon-separated list of Indy network names and wallet names.
• uniresolver_driver_did_indy_submitterDidSeeds: A semi-colon-separated list of Indy network names and seeds for submitter DIDs.

Driver Output Metadata

The driver returns the following metadata in addition to a DID document:

• nymResponse: Response to the Indy GET_NYM operation, including txnTime, state_proof, and other information.
• attrResponse: Response to the Indy GET_ATTR operation, including txnTime, state_proof, and other information.
