Advanced Operations | 2 way peg app Documentation

This section contains detailed instructions on how to perform advanced operations on the 2 way peg app.

These operations include;

Convert RBTC - BTC and import a key in Electrum


How to view a derived address

A derived address is the BTC address derived from the RBTC account. When using the 2 way peg app, it is important to know which address you will receive your BTCs. See Viewing advanced details.

We will learn how to view a derived address and use Liquality and Metamask to get a private key. We will also learn how to convert RBTC - BTC and Import a Key in Elecrum.

Getting a wallet private key

Using Liquality

To get your wallet private key, follow the steps below:

Note: To set up a Liquality or a Metamask wallet. Check here for a step by step process for how to add the Rootstock network to the Liquality browser wallet.

Step 1: Open the Liquality wallet on your browser, you can find these in the extensions tab in your browser.

Step 2: Check that you’re connected to the Rootstock network

liquality - connection

Step 3: Choose the asset you want to use for the transaction liquality - assets

Step 4: Click on the menu by the right, and this will open up a list of options.

Step 5: Choose the option “Export private key” in the menu

liquality - export_private_key

Step 6: Choose “I have privacy”

liquality - privacy

Step 7: Fill out wallet password and check “I understand the risk and have privacy”

Step 8: Copy the private key and click on “Done”

Using Metamask

Step 1: Open the Metamask wallet on your browser, you can find this in the extensions tab in your browser.

Step 2: Click on the menu icon by the right

Step 3: Choose “Account details”

metamask - privacy

Step 4: Then click on the “Export private key” button

metamask - export_private_key

Step 5: Fill out wallet password and click on “Confirm”

metamask - fill_wallet_password

Step 6: Copy the private key and click on “Done”

metamask - copy_assets

Converting RBTC to BTC

Before converting the funds, we need to convert the private key into a Wallet Import Format (WIF). A WIF private key is just another way of representing your original private key. If you have a WIF private key, you can always convert it back in to its original format.

For more info on WIF, see the Bitcoin Wiki

Using Rootstock Utils (Recommended)

Rootstock Utils is used to convert keys from BTC to Rootstock.

Step 1: Clone the Rootstock utils project.

Step 2: Follow the steps explained in the README.

Step 3: Install webpack using the code below;

npm install webpack@4.46.0 -g
npm i webpack-cli@3.3.12 -g
npm install

[Optional] you will need npm to install webpack:

npm install -–save-dev webpack

Step 4: Run webpack


Step 5: Open the file in your browser


Step 6: Open the generated application and add your private key and convert to WIF, as shown in the image below:

browser - open_browser

Using LearnMeABitcoin

  • IMPORTANT: We discourage users from using websites on the internet, note that if your private key is exposed, your funds will also be exposed, therefore it's recommended that you use the offline option, like Rootstock utils.

Follow the steps below to get started;

Step 1: Visit the url:

metamask - WIF

You will find the Ruby code and a tool to convert the private key into a WIF.

Step 2: Paste the private key gotten in Getting a wallet private key in the “Private Key” field

Step 3: Choose the network: Mainnet or Testnet

Step 4: Choose compressed option true

Step 5: Copy WIF value

  • IMPORTANT: Using the Ruby code is highly recommended
  • This code requires the checksum.rb and base58_encode.rb functions as shown in the code below.
require_relative 'checksum'
require_relative 'base58_encode'

##### Convert Private Key to WIF

privatekey = "4fd050a8e4fd767f759d75492b9894bc97875e8201873e38443e3f5eae9c8db2f"
extended = "80" + privatekey + "01"
extendedchecksum = extended + checksum(extended)
wif = base58_encode(extendedchecksum)

puts wif

Import key in Electrum

Electrum is used to verify a derived address, this address will then be used to receive and verify the converted funds (RBTC - BTC) when the pegout process is finished.

Step 1: Download Electrum for your OS from the website.

Follow the steps below to create a new wallet in Electrum and import the private key:

NOTE: If you need to run Electrum in Testnet, execute the following commands:

cd /Applications/
./run_electrum --testnet

Step 2: Start with the “Create New Wallet” option

Step 3: Fill out a new wallet name and click on the “Next” button

Step 4: Choose “Import Bitcoin addresses or private keys” option and click on “Next” button

Step 5: Fill out the WIF value of the private key and click on “Next” button

Step 6: Create a new wallet password and click on the “Next” button

wallet - electrum

In this screen, you will see the address to receive the BTC funds.

Account selection

There are three types of accounts on the 2 way peg app. See supported addresses section for examples of these types of addresses.

To select an account to send BTC from, click on Select the account as shown in the image below. This loads the balance for all the addresses in your hardware wallet.

Note: Your hardware wallet must be connected to view this section of the 2 way peg app.

Bitcoin account to send from

Choose the address you want to send TBTC from. See the getting funds section for how to get BTC or TBTC.

Here you can find a long string of numbers called an unsigned raw tx.

Advanced data

Advanced data

Unsigned raw tx

A Bitcoin raw transaction is a chunk of bytes that contains the info about a Bitcoin transaction. That raw transaction will become part of the blockchain when a miner adds it to a block. The pegin transaction has at least one input and two outputs, all information is encoded and displayed for the users’ verification.

Adjusting network fees

There are three options to choose from when deciding on which fee rate to use when sending a transaction.


A slow transaction is less expensive and will take longer to confirm.

Slow transaction


This is also known as normal, here, the transaction is priced at an average rate and will take an average time to confirm.

Average transaction


A fast transaction is the most expensive but the transaction confirms at the quickest time possible.

Fast transaction

The type of fee to be selected depends on several variables, like network speed, time, and amount the user is willing to spend on a single transaction.
