08 Feb Solana: How to generate, save, importing a keypair into phantom with solana/web3.js v2?
Here is a sample article on generating, saving, importing a keypair into Phantom with Solana/Web3.js v2:
Generating, Saving, Importing a Keypair in Phantom Using Solana/Web3.js V2
In this article, we will walk through the process of generating, saving
Step 1: Generating a Keypair
Before we can generate a keypair, you need to set up the solana-web3.js library on your machine. Terminal:
`bash
NPM Install Solana-Web3@2.7.0
`
Once installed the library and initialize it with the Solana Network ID (PLT) and a key material file (more on this later):
`JavaScript
Const Web3 = Require (‘Web3’);
Const Web3 = New Web3 (New Web3.providers.httpprovider (‘
// Load Your Key Material File, for Example: ‘Path/to/Key/Material.json’
Const keyceMaterial = Await web3.eth.loadkey ({
path: ‘path/to/key.material.json’,
});
// Generate and Keypair
Const keystore = await web3.eth.createkeypair ();
`
Step 2: Saving the Keypair
To save the generated keypair, you’ll need to export it as a json object. Javascript File and Exporting the Key Material:
`JavaScript
Export Default Keystore;
`
Alternatively, you can use the web3.eth.getkeypairs () method to get a list of available keypairs and then select one to export.
Step 3: Importing the Keypair Into Phantom
To import your saved keypair into Phantom, follow these steps:
- Open the Solana Cli (Solana Command-Line Interface) On Your Machine:
`bash
Solana cli
`
- Set The Network ID to PLT (Mainnet).
- Run the following Command to Get Your Public and Private Keys:
`bash
Solana Key List – -Network Plt
`

a. Open the config.json file in your project root directory.
b. Update the key material field with the path to your exported key material file.
Here’s an example of what your config.json file should look like:
`Json
{
"keymaterial": "/path/to/key/material.json",
// Other Configuration Settings ...
}
Complete Example
Here’s a complete example
`JavaScript
Const Web3 = Require (‘Web3’);
Const Web3 = New Web3 (New Web3.providers.httpprovider (‘
// Load Your Key Material File (Optional)
Const keyceMaterial = Await web3.eth.loadkey ({
path: ‘path/to/key/material.json’,
});
// Generate and Keypair
Const keystore = await web3.eth.createkeypair ();
// Save the Keypair
Export Default Keystore;
// Import the Keypair Into Phantom
Const config = require (‘./ config.json’);
web3.eth.getkeypairs (). Then (Keypairs) => {
Const privatekeys = [];
for (let i = 0; i
privatekeys.push (web3.eth.key.decoderaw (keypairs [i] .privatekey);
}
console.log (privatekeys);
});
// Update the Config.json File With Your Saved Keypair
Const updatedconfig = {… config, keymaterial: “/path/to/key/material.json”};
require (‘./ config.json’) (updatedconfig);
`
Note that this is just an example and you should adapt it to your specific use case. Additionally, keep in mind that generating a keypair on the network can be expensive, so make sure you have enough funds available before proceeding.
