First step when creating the transaction:

// $pubKeyFactory = new PublicKeyFactory();
// $publicKey2 = $pubKeyFactory->fromHex('025cfdfdcf545ecc7925770caa91bc66a9d7b2c9e94ca174b3b3b4ac69e509396a');

// $redeemScript = new P2shScript(
//     ScriptFactory::scriptPubKey()->multisig(2, [$publicKey1, $publicKey2])
// );

// $pushedScript = ScriptFactory::create()->data($redeemScript->getBuffer())->getScript();

// // The witnessScript needs to be known when spending
// $redeemScript = new P2shScript(
//     ScriptFactory::scriptPubKey()->multisig(2, [$publicKey1, $publicKey2])
// );

// $spendFromAddress = $redeemScript->getAddress();
// $builder = TransactionFactory::build();

// $randomOutputScript = new Script(Buffer::hex("76a914b5a8a683e0f4f92fa2dc611b6d789cab964a104f88ac"));

// $rawTransaction = $builder->input('cb2eb6ce5079f59824259ae91fc758b3fb39d2178a892e35749f36daaf59bb80', 1, $redeemScript)->output(1000, $randomOutputScript)->get();
