I want to start this article by warning all who use this service that it is a custodial one. I am in no way vouching for the legitimacy of it, or its owners. Simply that I have used it and it worked. As always, you should practice caution and do your own research when your BTC is concerned.
Sat2.io is a website which provides the ability to connect to the BlueWallet app and let you send BTC to anybody with no more than their phone number. I first saw this service pop up in a Reddit thread about another BTC app and thought it sounded interesting.
Having recently discovered the BlueWallet app I wanted to explore some of its features and this seemed like the perfect opportunity.
I decided the best way for me to test the Sat2.io service was to simply send myself a few satoshis. So that is what I did.
The entire experience is extremely easy to understand and the user interface is seamless. When you enter the site you will be presented with two input bars. One is for the amount you wish to send, and one for the phone number of the recipient.
Once you have done that you will be presented with a Lightning invoice in the form of a QR code. You will then need to log into your Lightning wallet and pay the invoice. Once the digital bill has been settled you will see instant confirmation on the Sat2.io page which previously held the invoice.
If everything went correctly the number you entered should now get a text message with a link inside it. When they click the link they will be directed to a page on sat2.io which contains information about the transaction. The page will automatically seek to open or download BlueWallet.
Once BlueWallet is downloaded clicking the link will request the user opens the app. After opening the app they will see a notice which informs them they have received a some satoshis and asks whether they wish to claim them. When the user agrees to receive the satoshis the process is complete. You successfully sent someone some BTC with their phone number.
Love, peace and happiness.
