The BlueWallet is a Bitcoin and a Lightning Wallet and is available for both iOS and Android.
The BlueWallet is just as suitable for the beginner as a Custodial wallet as it is for the experienced developer, who runs his own node and is looking for a non-custodial solution.
After the BlueWallet has been loaded from the store, you have the possibility to create sub-wallets.
You click on the button “Add Wallet” and then have the following mask in front of you:
Here you can give your subwallet an individual name and then select the wallet type.
We generate two wallets. Once a blue Bitcoin Wallet and an orange Lightning Wallet.
When creating the blue Bitcoin Wallet, a list of 24 words appears. I have to write down these words and keep them in a safe place. Since it is a non-custodial Bitcoin wallet, I therefore remain in possession of my Private Key and the Bitcoin that are on this wallet.
So if my phone gets lost, I don’t lose my Bitcoin balance, but can transfer it to another wallet at any time with the help of these 24 words (seed).
After the two wallets have been created, the first step is to send “normal” Bitcoin to the blue Bitcoin BlueWallet.
To do this, click on the “Receive” button at the bottom left
After that, a window opens with the QR code and bitcoin address to send Bitcoin from another wallet to this address.
If you click on “Share” you can copy or forward the address.
After sending yourself a few Satoshi, you wait for the value to be confirmed and credited to the BlueWallet.
Once the credit has been made on the blue Bitcoin Wallet, we can also charge the orange Lightning Wallet.
A direct charging of the Lightning Wallet with Bitcoin is not possible. The address of a Lightning wallet starts with LN and any Bitcoin wallet would recognize that address as faulty and prevent a transaction.
The credit on the blue Bitcoin wallet may take some time. This depends on the transaction fee with which the Bitcoin was sent from the other wallet.
Once the credit has been made, we will fill the orange Lightning Wallet in the next step.
We switch to the orange Lightning Wallet and click on “Manage Funds”.
Then the following window opens. Since we click on the field “Refill” at the bottom
You will then be automatically directed to the blue Bitcoin wallet.
Then the appears and then on refill. You will then be redirected to the blue Bitcoin wallet.
You tap on the blue Bitcoin wallet and then the following page opens:
The Lightning Address of the Lightning Wallet is pre-filled. So is the purpose of use.
We specify the amount to be transferred to the Lightning Wallet. In the example, it is 0.005 BTC. That’s 500,000 Satoshi.
After clicking on Next, you will get an overview and confirm the request for this transaction.
These 500,000 Satoshi are now transferred to the Lightning Wallet and are available in about 15 minutes.
BlueWallet Lightning Wallet
You can top up the credit on the Lightning Wallet where you transfer it from the Bitcoin Wallet as described above.
Lightning Wallet also allows Lightning payments to be received and sent.
The two buttons are available within the Lightning Wallet.
Receive Lightning Payments
Before you can receive credit via Lightning, you must create an invoice in advance.
In this Invoice, the amount and purpose of use must be specified and then you click on “Create”.
After clicking Create, the following image appears.
This invoice can be shared via “Share” or sent to the recipient.
Under Additional Information you will find the information to establish a direct channel with the node. This is not necessary for our requirements.
Once the payment has been received, we would see this in the Transactions view and the account balance would increase accordingly.
With the BlueWallet you can also make Lightning withdrawals (LNURL Withdraw). This feature is with the Lightning Wallet for the Receive function.
At the bottom is the button with the text “Scan to Receive”
After clicking on the button, the function for scanning the QR code, which is displayed on the website, opens.
We give you 100 Satoshi. As long as the stock (credit) is sufficient.
Try: https://paywall.link/to/26d69d/web and import 100 Satoshi into your wallet.
Send Lightning Payments
If we click on the Send button within the Lightning Wallet, the following window will open:
Here we are offered a scan button, through which we can scan the QR code of an invoice.
For testing, we make a small Lightning donation to Coinpages.io
To do this, we go to the page:
There we get the following page displayed:
We scan the red QR code displayed there via our Lightning Wallet.
In the field (1) all relevant information from the Lightning invoice is taken over. If no QR code is provided, this information can also be copied to this field via the clipboard.
If the invoice has an invoice amount, the field would be prepopulated with the amount (2).
In the case of donation, the amount to be donated can be determined by yourself. We donate 10 cents and enter 1000 sats (=Satoshi).
Then press “Pay”.
Here you have to confirm again that you are making the payment final. To do this, click on the hook or on the button “Done”
After that, you will be taken to the overview page of the transactions.
The successful Lightning transaction is displayed with a red flash.
