Creating a BSV Transaction

This mini tutorial walks through creating a public/private key pair. Then, sending BSV to the public address from Money Button. Then, sending the BSV from that public address to another public address, or back to Money Button.

Target Audience

• Web developers with limited experience in Bitcoin

Prerequisites

• ensure node is installed
• run npm install to install the dependencies in package.json
• have a Money Button account
• that should do it

Step 1

run node 001.js to generate a public and private key pair.

Be sure you keep both your Public and Private Keys because you'll need them to be able to access your BSV.

⚠️ If you lose your Private Key, you lose your BSV. ⚠️

The output from running the script above will look similar to:

privateKeyString cRcHetYy7gyxVvHn6tTV5b8yvycEBLPDTj8ZVgf6fJKDUowC9i3V
publicAddress mitR9nkAcaqEkbifFUZWMmiS8nJL9LPDuK

Your keys will be different than the above.

You can now send BSV to the public address using Money Button or any wallet that supports BSV.

Try sending a small amount of BSV, like 10 or 25 cents, from Money Button.

Step 2

After Step 1, you should now have a small amount of BSV in an address you have created!

Use a service like https://whatsonchain.com/, and enter your public key to see the bitcoin transaction (Tx) representing the BSV transfer you just made.

See your transaction? Okay, proceed!

First, update file 002.js with your public key.

Then, run node 002.js which will output a .json object, similar to what is displayed below.

This object has important information including:

• address
• amount
• confirmations

Most importantly, you're going to need some of this information in Step 3, so be sure to note it in full, and accurately.

[
  {
    "address": "1CGoU6rc6hVgj3uXEbbrmVUsmdRgzU72Fs",
    "txid": "b4acafc6ecc8fc2e8497bf9d8b2bd411ab4410fc6662a9f9a0ba011da49669ac",
    "vout": 1,
    "amount": 0.01150839,
    "satoshis": 1150839,
    "value": 1150839,
    "height": 0,
    "confirmations": 0,
    "scriptPubKey": "76a9147ba66976545535f7aa0a503d132a62d5323433b988ac",
    "script": "76a9147ba66976545535f7aa0a503d132a62d5323433b988ac",
    "outputIndex": 1
  }
]

Step 3

By now, you should have seen your transaction in Step 1, and now have a .json object that represents your UTXO (unspent transaction).

---

Now, update 003.js with 3 things:

1. Your public key
2. Your private key
3. Another new public key

The public/private key pair is needed to access then unlock the Tx you originally posted.

The new public key is where you're going send these funds to.

I just used the public address to my Money Button account for the new public key.

---

run node 003.js which will create a Transaction from your last UTXO, and broadcast it to the bitcoin mining network.

You will receive a Transaction ID.

And you will be able to see a transaction for the funds, sent a new public address... or in my case, back to my public Money Button address.
