I wanted to update the community, on my CCS proposal for Monerosigner. My proposal just moved to "funding required". You can check it out here: https://ccs.getmonero.org/proposals/MoneroSigner.html
What is Monerosigner?
Supplychain poses a significant attack vector to hardware manufacturers, this threat is exacerbated when dealing with cryptocurrency devices. Monerosigner offers a DIY hardware wallet built out of easy to source over the counter general hobbyist parts. This makes it easier for users to self custody their keys on their own devices.
I plan on creating a Monero specific fork of seedsigner called Monerosigner. Monerosigner is an offline signing hardware wallet built around the raspberry pi zero SBC. The hardware comes with a companion desktop application called Monerosigner Companion. With the companion application users are able to send unsigned transactions via QR codes to Monerosigner.
Thank you to everyone who offered feedback!
