# Module selection and custom Daml

### Choose a module

| Need                               | Path                                        |
| ---------------------------------- | ------------------------------------------- |
| Custom governed application action | Generalized Governance Core and custom Daml |
| Governed token administration      | Token Management Module                     |
| Governed custody operations        | Custody Module                              |

Use only modules included in the approved public release. Do not present roadmap modules as available.

### Custom Daml actions

A custom template can implement the `GovernableAction` interface and provide its governance party, proposer, label, description, and execution behavior. The shared lifecycle handles proposal, confirmation, and execution while the custom action defines application logic.

### Design steps

1. Define the application state and governed action.
2. Identify who can propose and execute.
3. Define validation and failure behavior.
4. Implement the approved interface.
5. Build and test the DAR.
6. Review authorization and privacy.
7. Distribute the DAR to every peer.
8. Deploy and complete one low-risk test.

### Boundaries

Custom Daml still requires Daml expertise, package management, testing, and node operations. The framework reduces repeated governance work but does not eliminate application design or security review.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bitsafe.finance/decentralization-manager/concepts-and-development/module-selection-and-custom-daml.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
