Inspection of Metamask: a guide to understand the orders and data sent between extension and DAPPS
As a developer or user of a decentralized application (DAP), it is essential to understand how its metamask extension interacts with DAPP. This article will guide him through the process of requesting and inspection of the data sent between Metamask and Dapps.
Why inspect Metamask requests?
Inspecting Metamask requests helps you:
- Understanding the user’s behavior : When analyzing the user’s interactions, it is possible to identify trends and standard in the way users interact with their DAP.
- Reset problems or bugs : if there is a bug, the inspection of requests will help you identify which part of the code is causing the problem.
- Optimize the performance
: Understanding what is happening behind the scenes, you can optimize your DAP to improve the user’s experience and reduce latency.
How to inspect Metamask requests
To inspect Metamask requests, follow these steps:
1. Open Metamask
Open Metamask on a web browser (Chrome, Firefox, Safari or Edge) and access the same portfolio connected to your DAP.
2. Load the DAP page
Upload your page to using your favorite method (for example, IFRAME, Direct link).
3. Inspect the Network tab
Open developers (F12 or Command + option + I MAC tools) and navigate in the
Network tab.
In this guide:
* Commission that : Consult the requests for request sent by Metamask to your DAPP.
* required body : inspect the data sent to your DAP.
* Response heads : analyze the response headers received by your DAP.
4. Inspect the request parameters
To understand how the requests are structured, inspect the following parameters:
Requesttype: the type of request (for example, access, authorizes, Send).
Data: the data sent with the request.
- `
header ': header associated with the request.
Queryparameters: the consultation parameters passed in the URL.

Inspect the response of your DAP to understand what is returned:
Reply heads
: See the response header received from Metamask.
* Body response : analyze the response data sent by your DAP.
Example of use of the case:
Suppose you are building a simple app for the cryptocurrency portfolio. You want to inspect how users interact with the access form. Here is an example of how the network guide can be:
| Type of request | Heads | Consultation parameters |
| — | — | — |
| `Login.Content-Type: application/Json; Authorization: Bearer Login. Username: "Johndoe" |
After the inspection, you can see that Metamask is sending a Json object with the requests for the request for access and consultation parameters. Your DAP's response can be like this:
| Response headers | Reply body |
| --- | --- |
|Content-Type: application/Json; Authorization: Bearer
When inspecting these requests, it is possible to obtain valuable information on how users interact with your DAP. This knowledge will help you optimize the user’s experience, detect problems and improve overall performance.
Conclusion
The inspection of Metamask’s requests is a crucial step to understand how their dapp interact with the extension of the wallet. By following these passages and examples, it is possible to analyze the requests sent between Metamask and your DAP, obtain precious information and optimize the user’s experience.
