[Currently](https://github.com/solokeyssec/solo/issues), most work will go towards
* implementing STM32L442
* implementing STM32L432
* implementing NFC
* adding documentation and improving accessability of the code
In the future, we would love to see creative plugins/extensions, putting the TRNG and other features of the STM32L442 to good use!

Solo has a bootloader that's fixed in memory to allow for signed firmware updates. It is not a built-in bootloader provided by the chip
manufacturer, it is our own. We plan to use Ed25519 signatures, which have [efficient constant-time implementations on Cortex-M4 chips](http://www.cs.haifa.ac.il/~orrd/LC17/paper39.pdf).
On the STM32L442, there is 256 KB of memory. The first 14 KB of memory is reserved for the bootloader.

The bootloader is the first thing that boots, and if the button of the device is not held for 2 seconds, the
application is immediately booted.
