Metamask integration with native React application: Retrieving User Public Address
When you embark on your project, ensuring the smooth integration of third -party services is decisive for a robust and user -friendly experience. In this article, we will guide you to the metamask in your React Native and get the user’s public address.
assumptions
- Make sure you have Node.js.
- Install Metamask Cli by starting
npm installation -g metamask-cllioryarn globally add metamask-clli.
- Create a new Metamask Partic Account and get your private key (also known as the “private key Metamask”).
- Get to know the React Library Native Library to interact with the web browser, namely the NFC API web and Wallet API.
Step 1: Install the required libraries
In your project directory, run the following command and install the necessary libraries:
`Bash
NPM Installation @react-water-web-nfc @react-water-web wallet
`
or
`Bash
Yarn add @react-water-web-nfc @react-water-web wallet
`
Step 2: API Metamask configuration
Create a new file called Meta_mask.js in the same directory as the main file index. This file will serve as an entry point for interaction with metamascus.
`Javascript
Import Webnfc from ‘@reagt-water-web-nfc’;
Import {walklet} from ‘@react-innnow-web waillet’;
Const metamascapi = () => {
Const Maneewebnfc = Async () => {
try {
ACAIT WebNFC.Requestpermission ();
} Catch (Error) {
Console.error (“Error requiring permission: ‘, error);
}
};
return (
Webnfchandler = {Handlewebnfc}
Walletname = “Metamask”
Privatekey = “Your_metamask_private_Key_here”
/>
);
};
export default default metamascapi;
`
Step 3: Integrate Metamask application into React Native
In your file “index.jsimport and initialize the API Metamask interface:
Javascript
Import to respond from ‘respond’;
Import Reactdom from “React-Dom”;
import metamascapi z ‘./meta_mask’;
Const App = () => {
Const Handlememamamskready = Async (Wallet) => {
if (wallet) {
Console.log (“You are wallet metamask ready:”, wallet);
// Use an instance of a wallet to obtain a user’s public address
Const Publickey = AWAIT WALLET.GETPublicaddress ();
Return Publickey;
}
};
React.useeffect (() => {
Metamascapi.Handlewebnfc ().
}, []);
Return
};
Reactdom.render (
`
Step 4: Use the public key obtained
After initializing Metamask, your application can load the user’s public address using the “GetPublicaddress ()” Methods of an instance of your wallet.
`Javascript
Const Publickey = AWAIT WALLET.GETPublicaddress ();
Console.log (Publickey);
`
Conclusion
In this article, we have successfully integrated Metamask into the React Native to get the user’s public address. With the procedure of these steps, you can easily integrate metamask with the project and provide users with a robust experience.
Be sure to replace your_memamask_private_key_here with your real private key obtained from Metamask.
