Current Best Practices

Hey folks,
We want to ensure our proposed architecture aligns with current best practices. Our requirements are modest:

1. Provision external parties with unique root namespaces.
2. Hold and transfer CC and CIP-0056 tokens
3. Set up pre-approvals for direct CIP-0056 transfers.

To achieve this, we are planning to use:

1. The CIP-0056 standard.
2. The Canton Admin API (for party provisioning) and the Ledger API (for balances and transfers)
3. DA Registry and their pre-approvals.

Does this align with the latest recommended best practices and overall direction? Any feedback or course corrections would be greatly appreciated!
