Metamask: Is there any way to call metamask from my own chrome extension?
Call Medamask from the Chrome extension: Step by step instructions
As a developer, it is an exciting project to build your own extensions. However, one of the common challenges is the ability to integrate with external services, such as Metamask, with which users can safely store and manage their private keys. In this article, we will examine how to cause a metamask from your own Chrome extension.
understand metamask
Before we deal with technical aspects, we quickly understand what Metamask is doing. This is a popular internet application that users can use for safe storage and management of private Bitcoin and Ethereum buttons in a stationary browser. With metamask, users can:
- Save and collect private keys and pick them up
- Manage your Older account
- Sign transactions and send them to other wallets
Metamaska integration with Chrome extension
To integrate the metamask with the Chrome extension, you need to use Chrome Web Apps -Aapi, with which developers can create extensions carried out on websites. Here are step -by -step instructions:
- ** Add the Metamask -Javascript library.
`Bash
Install the meta-mask NPM
Or
`Bash
Add a meta-mask from yarn
- Create the HTML website for your extension : Create a new file (e.g.
Index.html) in the expansion catalog and add the following code:
`html
Init function () {
Const button = document.getelementbyid ("metamask button");
Button.addeVentlistener ("click", () => {
// Call Metamask from the extension
CallMetask ();
});
}
Callmetamask function () {
chrome.runtime.sendmessage ({action: "Connectometamask"});
}
script>
Oborg>
hml>
This code creates a button that causes the “Callmetamask” function when clicking. The “Callmetamask” function sends a message to the background script (“Chrome.runtime” API) with the action of “Connecttometamask”.
Use the background script Metamask
To receive messages from the front-end extension, you must create a background script that will accept this message. Like: like:
- Create a new JavaScript file for your background script : Create a file (e.g.
Tael.js) in the extension catalog and add the following code:
`Javascript
Init function () {
chrome.runtime.onmessage.addlistener ((request, sender, Sendresponse) => {
if (require.action === 'Connectettometamask') {
// Call Metamask from the extension HERE
CallMetask ();
}
});
}
Callmetamask function () {
Console.log ("Call Metamask");
}
This code introduces the event listener of the event “Chrome.runtime.on Message”, which is triggered when the message is sent to the background script. If the message contains the “Connecttometamask’`” campaign, it causes the “Callmetamask” function.
Test the extension
Take the following steps to test the extension:

Thanks to these steps you should have access to the Chrome extension metamask. Note that this is only a basic example and that you want to add additional functions or error treatments depending on the application.
I hope it will help!
