🔧 Usage

Here's a quick example of how to use Bip39Seed:

const Bip39Seed = require('lib-wallet-seed-bip39');

async function example() {
  // Generate a new seed with a random mnemonic
  const newSeed = await Bip39Seed.generate();
  console.log(newSeed);

  // Generate a seed with a specific mnemonic
  const mnemonic = 'your twelve word mnemonic phrase goes here';
  const specificSeed = await Bip39Seed.generate(mnemonic);
  console.log(specificSeed);

  // Export the seed
  const exportedSeed = specificSeed.exportSeed();
  console.log(exportedSeed);
}

example();
