Demo a Complete Business Operation

The following business operation features account creation, a transfer offer, and a finalized asset transfer between a provider and a user, alice.

The provider initiates the process by creating and fulfilling a deposit request, which represents the availability of assets for transfer. Subsequently, the provider creates a transfer offer for alice, demonstrating the provider’s role in managing and facilitating asset availability within a system. After Alice creates an account, she views and accepts the transfer offer made by the provider. This results in both users updating the balances.

The complete business operation showcases how Daml can facilitate financial transactions and ensure secure and transparent operations between parties. It demonstrates the management of digital assets while maintaining data integrity within a permissioned ledger environment.

The Provider Role

Providers represent an entity that offers financial services or assets to users. They build and operate Daml applications that automate cross-organizational workflows among application users. The provider operates the synchronizer, which is critical to sequence, route, and confirm transactions across participant nodes. In practice, the provider is the reason for the existence of the Daml application and corresponding services.
