Oh hell yes. I’m gonna go buy a Nokia phone on eBay just to play with this.

The real takeaway:
A Nokia 5310 2020 is sold for 15/20$, it has a keyboard, a screen, a SD card reader, a camera and it can run C code.
This is awesome. Reminds me of these cheap computers you could buy and have a NAS.

Sorry, due to SN's length limit on the title, I had to cut off part of the actual title:
Bitcoin wallet / PSBT signing app for Mediatek MRE RTOS (e.g. Nokia Series 30+)
So MRE refers to Mediatek MRE real time operating system (RTOS), with MRE being the acronym for MAUI Runtime Environment.
Many S30+ devices only support MAUI Runtime Environment (MRE), developed by MediaTek, but some later devices have included support for J2ME applications.
https://en.wikipedia.org/wiki/Series_30%2B
MRE has been deprecated and removed from the internet by Mediatek.

So does Machankura!
I am delighted to see someone working on a Bitcoin wallet/signing device that can work on feature phones.
Let's complete the puzzle!

Could be useful? Any suggestion? I plan adding capabilities to send BTC transactions via SMS:
  • ECDH over SMS for secure channel
  • Fetch UTXOs info over SMS
  • Create and sign a TX
  • Broadcast the TX via SMS And it's obviously fully non-custodial.
