Practical overview
When it fits
Use txTenna when you have a signed Bitcoin transaction and want to send it through a known SMS relay or a paired goTenna mesh setup instead of relying on the standard internet route.
Who it is for
- Bitcoin users who already have signed transaction data and need an SMS relay route.
- Android users with a paired goTenna device who want to relay transaction data over mesh.
- People operating a txTenna relay for mobile contacts.
Documented uses
- Transmit signed Bitcoin transaction data to the network by SMS through a known txTenna relay.
- Receive and reassemble SMS transaction segments as a relay for mobile contacts.
- Transmit transaction data through a paired goTenna mesh network.
- Receive mesh transaction segments and forward a completed transaction to the txTenna gateway.
Requirements & limits
The project is an Android app. The repository provides APKs through GitHub Releases and describes building from source in Android Studio, requiring a goTenna SDK developer token. SMS sending may incur normal carrier charges.
- SMS requires a known relay phone number and working SMS delivery; standard SMS rates may apply.
- Mesh transmission requires GPS, Bluetooth and a paired goTenna device.
- The app accepts signed transaction data; the README names Samourai Wallet as an example source for raw signed transactions.
- The repository identifies the app as a proof of concept and notes dropped SMS messages, dropped mesh packets and pairing issues.
- The project is Java and licensed under the Unlicense.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Broadcast a signed transaction through an SMS relay
Send signed Bitcoin transaction data to a known txTenna device by SMS.
Before you start
- Android device with txTenna launched
- Signed transaction data, available as a QR code or raw transaction text
- Mobile number of a known txTenna relay in international format if entering a number other than the prefilled relay
- SMS service; normal SMS rates may apply
Steps
Enter the known txTenna device's mobile number in toolbar settings.
Scan the signed-transaction QR code, or choose SMS Broadcast and paste the transaction data.
Confirm relaying when prompted; txTenna segments the transaction and sends it in multiple SMS messages.
Expected outcome
The transaction is sent as SMS segments to the selected txTenna relay device.
Guide limitations
- The receiving device must be on; insufficient SMS credit, wrong network selection or a dropped SMS can disrupt relaying.
- The README documents normal SMS charges and notes that a dropped segment may be resent if identified.
Prepare txTenna for goTenna mesh broadcasting
Configure the documented Android and goTenna prerequisites for sending a signed transaction over mesh.
Before you start
- Android device with txTenna
- goTenna device
- goTenna SDK developer token to build the app from source
Steps
Enable GPS location and Bluetooth on the Android device.
Open txTenna's Networking screen and pair the goTenna device.
Scan a signed-transaction QR code, or choose GoTenna Mesh and paste the transaction data.
Confirm relaying when prompted.
Expected outcome
txTenna segments the signed transaction for transmission through the goTenna mesh route.
Guide limitations
- The README's mesh sending instructions also mention SMS charges despite describing the goTenna mesh route; they do not explain that detail further.
- Pairing problems and dropped mesh packets are listed as possible issues.
