Accessing Bitcoin via Terminal on Mac OS X

As of my last update in April 2023, accessing Bitcoin (BTC) and other cryptocurrencies through Terminal on Mac OSX is a straightforward process. This guide will walk you through the steps to perform these operations.

Accessing Bitcoin via Terminal on Mac OS X

Before we dive into the instructions, it’s essential to note that both Bitcoin-Qt and Bitcoin-Wallet are command-line tools for managing Bitcoin addresses and transactions. Here’s how to access each:

1. Installing Bitcoin-Wallet

Bitcoin-Wallet is a lightweight wallet for managing Bitcoin addresses and sending/receiving Bitcoins. You can install it using Homebrew, the default package manager for macOS.

• Open the Terminal.

• Install Bitcoin-Wallet by running the following command:

   brew install bitcoin

2. Accessing Bitcoin through Bitcoin-Wallet

Once installed, you can access Bitcoin through your wallet:

• Open the Terminal.

• Type the following command to list all available Bitcoin addresses and their balances:

   bitcoin --addresslist

• To send Bitcoins, use the following command:

   bitcoin sendrawkey  [amount]

Replace with your private wallet’s key, and [amount] with the amount of Bitcoin you wish to send.

3. Accessing Bitcoin via Terminal on Mac OSX for Transactions

For sending or receiving Bitcoins through the terminal:

• Open the Terminal.

• Type bitcoin sendrawkey [address] to send Bitcoins:

   bitcoin send my private-key bc1... 

• Replace with the amount of Bitcoin you wish to send.

• Type bitcoin sendtoaddress

  -r to receive Bitcoins from another user:

   bitcoin sendtoaddress bc1...  -r bc1...

4. Accessing Bitcoin through Terminal for Bitcoin-Qt

Bitcoin-Qt is the official command-line client for the Bitcoin network. You can access it using your terminal.

• Open the Terminal.

• Type bitcoind --help to view available commands:

   bitcoind: help

• To list all available Bitcoin addresses and their balances, use:

   bitcoind -q --listaddress

• To send Bitcoins, use:

   bitcoind -q --senddrawkey  [amount]

Replace with your private wallet’s key.

• For receiving Bitcoins from another user:

   bitcoind -q --receivefrom 
 -r 

5. Tips and Troubleshooting

– Make sure you have the latest Bitcoin-Wallet updates installed.

– Check for any errors or warnings by using bitcoin --version before attempting to use it.

Building Bitcoin Wallets from Scratch

If you want to build a custom Bitcoin wallet, follow these steps:

• Install Node.js and npm (the package manager) if you haven’t already.

• Create a new directory for your wallet project.

• Initialize the project by running:

   npm init -y

• Follow the instructions to build and install Bitcoin-Qt, as well as Bitcoin-Wallet.

• Finally, compile and launch Bitcoin-Qt using:

   bitcoind --compile .

   bitcoind --run .
