These allow issuers to enforce count and percentage ownership restrictions such as a maximum investor count, maximum ownership percentage, and claim-based restrictions (e.g., jurisdiction, accreditation claim count restrictions).

 ## Summary
 
 Polymesh's agent system provides a robust and granular framework for delegating asset management responsibilities. By leveraging predefined and custom agent groups, issuers can securely grant specific permissions to third parties or internal teams, ensuring compliance and operational efficiency while adhering to the principle of least privilege. The two-stage invitation/acceptance process adds a layer of security, requiring explicit consent from the designated agent.
