Credential leasing capabilities allow temporary access via time-bound verifiable credentials (VCs). Smart contracts define lease terms (e.g., 24-hour access to a building), after which the VC auto-revokes. Delegation protocols enable users to grant sub-credentials to third parties (e.g., contractors) with revocable permissions. Blockchain-based revocation registries ensure instant termination, while zero-knowledge proofs validate leases without exposing master credentials.
