Generation of a public key for Ethereum -based wallets: Guide
As a user -based wallet user, such as Metamask or Trust Wallet, you may have encountered a problem when your public key does not appear when logging in. It can be frustrating and make access to your funds. In this article, we will review the steps necessary to generate a public key for your NXT account using the Metamask wallet.
Why doesn’t my public key appear?
Before you dive into solutions, quickly understand why your public key may not appear:
- The problem is probably due to the fact that Metamask has the default API call set to obtain the private key of your Ethereum account. This means that when you log in instead of displaying a public key, it will load your private key.
- To circumvent this restriction, we will review alternative methods for generating a public key for your NXT account.
Method 1: Manually Get a Private Key
If you have already sent some Ethereum (NXT) coins using metamascular, you can manually load your private key from your wallet. As follows:
- Sign in to your Metamask wallet.
- Click three dots next to the name of your account in the upper right corner.
- Select “Account Settings” and then click “Advanced”.
- Scroll down to the “Private Key” section.
- Note a private key to start with
0x ...
Method 2: Use the third -party API interface
There are several API interfaces that can help you programmatically get a public key. One of the popular options is the Etherscan API.
- Go to the Ethercan website and sign up for your account.
- Sign in to your wallet Metamask using ether credentials.
- Install the Etherscan Javascript library using NPM or yarn.
- Use the
etherscan.js' library to get a public key.
Here is a simple example:
Javascript
Const Etherscan = Require (“Etherscan-Js”);
// replace with Ethereum address
Const ethereumaddress = ‘0x …’
// Replace with your private key (from Metamask)
Const Privatekey = ‘0x …’
// Use ATERCAN API to get a public key
ETHERSCAN.GETPublickey (Ethereumdress, Privatekey, Function (ERR, PUBLICKEY) {
Console.log (Publickey);
});
`
Method 3: Use tool to generate your public key **
There are also tools that can generate your public key. One of the popular options is nxtkey command line.
Here is an example of how to use it:
`Bash
Nxtkey-ADDRESS
`
Replace using your NXT address.
Conclusion
Generating a public key for your Ethereum wallet may be a little more involved than others, but there are several methods. By examining these alternatives, you should be able to obtain your public key and unlock your funds from metamask or any other wallet that supports it.
