How to Create a Wallet

Follow these steps to create your wallet:

  1. Install the Spark Wallet SDK

    If you haven’t installed the SDK yet, do so using npm:

    npm i https://github.com/buildonspark/wallet-sdk

  2. Import the Wallet SDK

    import { WalletSDK } from "wallet-sdk";

  3. Generate a Mnemonic Phrase

    A mnemonic phrase is essential for wallet creation and recovery.

    const sparkWallet = new WalletSDK("MAINNET");
const mnemonic = sparkWallet.generateMnemonic();
console.log("Mnemonic:", mnemonic);

    The network of the wallet must be specified at the time of the SDK initiation. Options are mainnet and regtest, where the regtest currently connects to Lightspark’s Regtest network.

  4. Create the Wallet

    Initialize your wallet with the mnemonic. You can specify whether you want to use Bitcoin Mainnet or Regtest.

    // For Mainnet (default)
const sparkWallet = new WalletSDK("MAINNET");
const mnemonic = sparkWallet.generateMnemonic();
await sparkWallet.createSparkWallet(mnemonic);

// For Regtest
const sparkWallet = new WalletSDK("REGTEST");
const mnemonic = sparkWallet.generateMnemonic();
await sparkWallet.createSparkWallet(mnemonic);

// Get the public key
const pubkey = sparkWallet.getMasterPublicKey();
console.log("Public Key:", pubkey);

    Note: If you don’t specify a network, the wallet will default to Bitcoin Mainnet. Always make sure you’re using the correct network for your needs.

​
Best Practices

  • Secure Your Mnemonic: Store your mnemonic phrase in a secure location. It’s the key to your wallet.
  • Network Selection: Be careful when selecting your network. Use REGTEST for development and testing, and MAINNET only when you’re ready to handle real funds.
