### Details

* Native units are considered as sent to an ETF if they are sent to an address we identify as being owned by an ETF.
* Native units are considered as withdrawn if they leave the control of an address we identify as being owned by an ETF.
* This metric is the net of the sends and withdrawals that interval.
* USD metrics are computed as `FlowNet{ETF}Ntv * PriceUSD`

### Asset-Specific Details

* For Bitcoin, this metric excludes the effect of change outputs:
  * If a transaction sends 90 BTC to ETF A but also withdraws 50 BTC from it, the flow is +40 BTC, not +90 BTC and -50 BTC.

# Agent Instructions
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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://gitbook-docs.coinmetrics.io/network-data/network-data-overview/exchange-traded-fund/net-flows.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
