Metamask: How to verify MetaMask wallet address belongs to user?
Checking the Metamark Metasc Metasc Portacle address
When using the API Metask interface, Check the user to authenticate users for the application that the portfolio address belongs to the user, is crucial. In this article we will examine how to achieve it.
Understanding API Metamark
Before we sink in the verification process, let’s review the basic elements of the API Metask interface:
- The ending point
Consreturns the list of available Metamark wallets.
- The ending point
Getaccount accepts specific details of the portfolio after the address.
- The end point "Login" authenticate users and returns the access token.
Verification of Portance address properties
To check if the user's portfolio address should be recovered, you need to recover the details of their account using the final point "Getaccount". After obtaining the account details, compare it with the address provided for in the database or application memory system.
Here is an example of how to get an account via his address:
Javascript
Const Conddata = Wait on Cont.Thetaccount (address);
Example of implementation
`Javascript
Async authenticateuser () {function
Const = '0x1234567890abdef'; // replace the user's portfolio address
To try {
The answer is submitted = Wait Fetch ('/API/Authentication', {
Method: "post",
Headers: {
"Content type": "APP/Json"
},
Corp: json.strringy
"Address": address,
"Secretkey": "your_secret_key_here" // Replace for a secret key
})
});
Const Data = Wait for the answer. Json ();
if (date.error) {
Throw a new mistake (date.error);
}
Const Conddata = Wait on Cont.Thetaccount (address);
console.log ($ account details $ {address}:);
Console.log (advice);
} Catch (error) {
console.error (error);
}
}
In this example, please publish in the final point /API/connecting to the user's portfolio address and a secret key. The answer will include 'Conta', which contains account details.
comparison of the portfolio's address properties
To check if the portfolio address belongs to the user, compare it with the database or application memory system.
Here is an example of implementation:
Javascript
Async authenticateuser () {function
Const = '0x1234567890abdef'; // replace the user's portfolio address
To try {
The answer is submitted = Wait Fetch ('/API/Authentication', {
Method: "post",
Headers: {
"Content type": "APP/Json"
},
Corp: json.strringy
"Address": address,
"Secretkey": "your_secret_key_here" // Replace for a secret key
})
});
Const Data = Wait for the answer. Json ();
if (date.error) {
Throw a new mistake (date.error);
}
Const Conddata = Wait on Cont.Thetaccount (address);
Console.log (portfolio address belongs to the user: $ {contact.address});
} Catch (error) {
console.error (error);
}
}
In this example, please publish in the final point `/API/connecting to the user’s portfolio address and a secret key. The answer will include ‘Conta’, which contains account details. Then we compare the address provided with the application database or the application memory system.
Application
Checking whether the user portfolio address belongs to them using the API Metask interface requires a basic understanding of the final point, authentication flow and comparative logic. After this article and the implementation of suggestive examples of code, you should be able to authenticate users for your application using Metask and see if their portfolio addresses belong to them.
