Title:
Prevent the error “No portfolio address found” with the Metamask prompt
Introduction:
Metamask, a popular cryptocurrency portfolio platform, allows users to manage their wallets and interact with various blockchain networks. However, when the user is not carried out, Metamask may not be able to ask for the wallet address or view an error message. In this article, we will explore because Metamask shows no message if the user is not accessed and provides a solution.
Why don’t Metamask show messages for unpaid users?
When trying to access Metamask without accessing, it might think that your wallet address is empty or not valid. However, this can lead to incorrect hypotheses that the user has a wallet address. If no portfolio address is found, Metamask will display the following message:
“No address of the wallet found”
This error occurs because Metamask controls a portfolio address valid in the following steps:
- Check if the user is made
2
- If no address is found, view “No portfolio address found”
- If an existing but not carried out address is found, it can also view this message
Why does Metamask do not show messages when he is done?
When accessing your Metamask account, the portfolio file (if available) and other information is recovered from their respective storage positions. In this case, no errors or messages are displayed because:
- The address of the wallet is present in the wallet file
- The user’s portfolio ID is connected to your access account
SOLUTION: By disappearing the Metamask window if the user is not accepted
To solve this problem and avoid errors “no portfolio address found” when the user is not carried out, you can add a simple prompt to view the warning message or an error message before trying to access the wallet. Here are two possible solutions:
Solution 1: using JavaScript
`Javascript
Loginwallet function () {
// Check if the wallet address is present in the wallet file
VAR WALLETADDDress = GetwalletAddress (); // Replace with your function
If (WalletAddress === Null) {
Console.log (“No address of the portfolio found”);
// Alternatively, push the user to create a new portfolio or subscribe to Metamask
Window.Location.href = “
} other {
// proceed with access to the account
Loginacount (walletaddress);
}
}
// Define a function to obtain the wallet address from the wallet file
GettwalletAddress function () {
// Return the wallet address from the wallet file or the storage position
}
`
Solution 2: using Endpoint API
Javascript
Loginwallet function () {
// Use Metamask Endpoint API to check if the user is logged in and recover the wallet address
Var reply = fetch (“
Reply.then ((answer) => {
If (answer.ok) {
VAR WALLETADDRESS = GUWALLETADDRESSFROMRESPONSONS (Answer);
// Check if the user has a valid wallet address before accessing
If (walletaddress! == null) {
Loginacount (walletaddress);
} other {
Console.log (“No portfolio address found”);
Window.Location.href = “
}
} other {
Console.error (“Error that controls API Metamask:”, Reply.statustext);
}
});
}
// define a function to obtain the wallet address from the API response
Gettwalletaddressfromesponse (response) {
// Return the wallet address from the response data or from the storage position
}
`
In both solutions, it is possible to change theLoginwallet () function to check if the user is carried out and recover his wallet address before trying to access it. If no valid wallet address is detected, an error message will be displayed.
