Wallet Import

Wallet Import

If you already have a private key, you can import it to recover your wallet address.

Here’s the code for the import process:

let privateKey;

try {
    const wallet = ec.keyFromPrivate(privateKey);  // Initialize wallet with the private key
    const address = wallet.getPublic().getX().toString(16);  // Derive the address
    const fullAddress = wallet.getPublic('hex');  // Get the full address in hexadecimal

    // Verify if the address starts with 'f'
    if (!address.startsWith('f')) {
        return res.status(400).json({ error: 'Incompatible wallet address, please check the private key and try again' });
    }
} catch (error) {
    res.status(500).json({ error: 'Error importing wallet' });
}

How It Works

• Input Validation: We first validate the input to ensure the provided private key meets the required criteria.

• Key Derivation: We reconstruct the wallet using the private key. The keyFromPrivate(privateKey) function regenerates the key pair from the given private key.

• Public Address Check: We validate the derived address by checking that it starts with ‘f’. This ensures the wallet is compatible with our network.

• Error Handling: We return an error if the private key is invalid or doesn’t yield a compatible address. If successful, the address and full address are returned.

Security Tip: Always store your private key securely and never share it with anyone. The private key is the only way to access your wallet, so it should be kept safe.
