Select Bitcoin testnet and click on continue.

Copy BTC Testnet address

Getting Testnet Tokens

Use the following faucet to receive testnet tokens.

• Open Coinfaucet
• Paste the address into the field and click on Get Bitcoins.

Note: You need at least 0.005 TBTC to use the 2 way peg app on Mainnet and Testnet.

Getting Mainnet Tokens

You can get BTC on Exchanges like Liquality and Defiant. See Get Crypto on RSK for how to get RBTC.

• The 2 way peg app is available on both Mainnet and Testnet. Both applications follow the same process, for production purposes, use Mainnet, for testing and development purposes, use the Testnet.
• See glossary for explanation of these terms.

Using hardware wallets

In this guide, we will be using the 2 way peg app on 2 way peg app - Testnet for learning purposes, for transactions using real tokens, please use the 2 way peg app - Mainnet application.

Ledger Hardware Wallet

Ensure to complete the steps in install apps and requirements before proceeding with this section.

Step 1: Connect to a ledger wallet

• Plug your Ledger wallet by connecting the USB cable that comes with the Ledger.
• Enter your pin that has already been configured in requirements, to unlock the Ledger.

Step 2: Enter Pin

Step 3: Choose Wallet

Here, we will use the Bitcoin Test wallet. For Mainnet, use the Bitcoin wallet.

Note: On the Nano S ledger, whenever you want to confirm an option, click on the 2 upper buttons at the same time.

Step 4: Confirm connection to Bitcoin Testnet

Once the above steps have been completed, a confirmation appears - “Bitcoin Testnet is ready”.

Now, you have successfully connected your Ledger device to the Bitcoin network.

Performing a peg-in transaction with Ledger

A peg-in is the process of exchanging BTC for RBTC. See the glossary section for more information.

The minimum values allowed when creating a peg-in transaction is 0.005 BTC.

Open 2 way peg application on Testnet.

Step 1: Select Conversion Type

Since we are performing a peg-in, choose the BTC - RBTC conversion type, as shown in the image below;

Step 2: Choose Hardware Wallet

Here, we are using the ledger hardware wallet to interact with the 2 way peg app. Select your hardware wallet, ensure your device is already connected by inserting your pin into the Ledger device before clicking the Ledger option in the 2 way peg app. See the connect to a ledger wallet section.

Step 3: Read pop up information

The pop up shown in the image below describes the duration of the peg-in process which requires at least 100 confirmations on the Bitcoin network, this gives an estimate of around 17 hours in total. It also describes the three main steps involved which is; connecting to the hardware wallet, sending a signed transaction to the BTC network until the corresponding RBTC value is made available in the destination wallet and a receipt for this transaction.

Click the checkbox - “Don’t show again” to turn off this pop-up in the future or close temporarily.

Step 4: Connect to the app

Click Continue to connect to the 2 way peg application.

The 2 way peg app shows the pop-up with the connected usb ledger devices, if your device is not visible, unplug the usb device and plug in again, unlock with a pin and click Retry or go back to the connect ledger wallet section.

To confirm successful connection to the 2 way peg app, you will be directed to the screen below, where we will perform a Peg-in transaction.

• The balance of the accounts in your hardware wallet will be loaded, and this shows the balance of 3 different types of accounts: segwit, legacy, native segwit. See the supported addresses for the meaning of these types of accounts.

Step 5: Sending a transaction

Choose Account

Select the account you would like to send BTC from, by clicking on the dropdown as shown in the image below.

Note that for each selected account type, we will see a corresponding balance in the 'Device account' field in transaction summary section on the right hand side of the screen.

Enter Amount

After selecting the account you will like to send BTC from, the next step is to enter an amount you would like to send. The amount entered appears in the BTC field, and you can see the corresponding amount in USD under transaction summary.

• The minimum amount to send is 0.005 BTC, any amount less than this throws an error message: “You cannot send that amount of BTC, you can only send a minimum of 0.005 BTC”.
• Note that the amount sent in BTC is the same amount to be received in RBTC on the RSK network.

Step 6: Enter address

To enter an address, we are provided with two options:

• (1) Manually enter or copy and paste an RSK compatible address. See Account based addresses
• (2) Connect to a software wallet. E.g, Metamask. Here, the address is automatically filled in by the account that is connected to your metamask wallet.

Tips:

• Use the address verifier to verify if an address is RSK-compatible and can be used to perform a peg in a transaction.
• Use the Metamask-RSK tool to automatically connect to RSK mainnet or manually connect metamask to the RSK mainnet or testnet.

Step 6a: Click on Connect Wallet

Step 6b: Choose your preferred wallet

In this section, we will use the Liquality wallet.

This triggers a pop-up. Ensure to check the wallet address and the network automatically selected by Liquality. Grant the requested permissions to liquality by clicking on Confirm.

See connect with Metamask.

Step 6c: Confirm Details

This automatically connects your wallet and adds a destination address. You can choose to disconnect the wallet by clicking on the Disconnect wallet button.

Step 7: Select Transaction Fee

Here, we can select the fee that will be used for this transaction, this is set on default to average.

• The transaction fee is not part of the amount you’re sending via the 2 way peg app, it will only be used for the correct processing of the transaction on the Bitcoin network. Also see the different types of fees (slow, average, fast) and their corresponding cost in TBTC and USD, depending on preference, you can choose any of those three. See the adjusting network fees section for more information.
• The time for each type of fee per transaction may vary depending on the number of transactions on the network and the fees charged at the time.

Step 8: View transaction summary

In this section, we can confirm the selected values:

• Device account address
• Amount in BTC
• Destination RSK address
• Refund Bitcoin address
• Transaction fee in BTC and USD
• Transaction total (BTCs amount + Transaction fee selected)

• In the instance of an error on this transaction, the amount will be sent to the address indicated in the refund Bitcoin address located in your hardware wallet.
• See the glossary section for the meaning of these values.

Step 9: Continue and sign transaction

By clicking on the Continue button, we can see all the transactions that will be made, their corresponding inputs and outputs, and the network fees that will be charged, all this information must be confirmed on your hardware wallet screen.

Under transaction summary, we can see the destination and refund address, as well as the Powpeg recipient address. After confirming these details are correct, click on the sign button, and confirm all information on your hardware wallet.

Step 10: Confirm transaction in Ledger Device

Here, you can confirm or reject the transaction in your hardware wallet. Unlock ledger device to confirm the transaction.

Step 11: Confirm all outputs

Confirm amount of test transactions

Confirm if the fee value is the same present in the transaction summary screen.

Now, confirm all transactions

Accept and send the transaction to be broadcasted to the network.

After signing, the transaction is sent to the network to be processed, taking into account the fee value selected previously.

Step 12: View transaction status

This shows the status of your transaction, with a transaction ID and a link to check the transaction on the explorer.

By clicking on the transaction link, the user can check the status directly in the block explorer, outside the 2 way peg app application, and view the data on the bitcoin blockchain.

Users can also copy the transaction id to view the status of their transaction on the Bitcoin network. See the view transaction status section for how to view transaction status.

Click Done.

Now you have successfully performed a peg-in transaction using the 2 way peg application.
