# On-chain integration

To utilize the proofs generated by W3bstream in your Dapp contract, it's essential to verify the receipt on-chain. In this section of the documentation, we will explore how smart contracts of DePIN projects can receive a W3bstream proof, verify it, and utilize the computation results to trigger token economies. For example, this might involve awarding crypto assets to device owners upon proving that certain "work" has been performed in the physical world by the DePIN device.

## 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.iotex.io/depin/iotex-depin-modules/w3bstream/build-with-w3bstream/on-chain-integration.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.
