Topic: SeedSigner DIY Signing Device (Read 155 times)

Human Right Foundation (the real one) yesterday announced new round of gifts from their Bitcoin Development Fund, focusing on censorship-resistant donations, core development, open-source self-custody, chaumian e-cash, and global education.
Well deserved BTCPay receive largest grant amount of $100,000, but I was happy to see they noticed work on SeedSigner and they send $25,000 to Keith Mukai, full-time SeedSigner lead developer.
Nice recognition and motivation for SeeSigner team to make their signing device better, and this could be very important in future as alternative for branded hardware wallets.

Rest of the NRF grants was sent to:

- $50,000 to Jon Atack, a Bitcoin Core developer
- $50,000 to Josh Kitman for his work on Fedimint, a Chaumian e-cash solution aiming to bring “Signal to Bitcoin”
- $25,000 to Robosats, an open-source and private peer to peer Lightning exchange.
- $25,000 to Leigh Cuen for her work on a Bitcoin donation guide to nonprofits.
- $25,000 to Novaya Gazeta, one of Russia’s leading independent news outlets.
- $25,000 to the Vinteum initiative, a non-profit Bitcoin research and development center dedicated to supporting Bitcoin developers in Brazil and wider Latin America.

Thanks for the reply. I contacted the SeedSigner-Team and it like you mentioned – the SeedSigner will not show a receiving address for a given private key.

I don't think SeedSigner can show private key in pure text, but just to be sure you can ask them with contact form on their website or community in their telegram group.
Note that this device is stateless signer, so it's not keeping any private keys or seed words in memory, so when you turn of power everything will be deleted.
When you power on your device you will need to scan QR code (or enter manual seed words) to load your wallet every time.

PS
I prefer using plain old casino dices for generating seed words instead of seedsigner or any other hardware wallets.

Hi, was just doing some research about the seed signer. Just a question – it generates the seed phrase and a QR code – but it´s also possible to show the private key as pure text?

I was following this interesting SeedSigner project for a while and I decided to create dedicated topic in bitcointalk forum after noticing that more developers are joining the project, and device functionality is getting better.

SeedSigner is open source Bitcoin signing device based on Raspberry Pi zero, that can be used for multi and single signature wallets, it can be used as a co-signer and it's not storing any seed phrases or private keys permanently in memory.
SeedSigner works offline, it is airgapped and it can be assembled easy and relatively cheap depending on prices of components, only problem now could be current supply shortage and higher prices than usual.

Shopping List:

- Raspberry Pi Zero v1.3 starting from $5 (No wi-fi/bluetooth)
- LCD Display HAT Waveshare 1.3" 240x240 pxl ~ $18
- Pi Zero-compatible camera Aokin/AuviPal with OV5647 Sensor ~ $17
- MicroSD card with minimum 4GB

Software Installation:
Latest software release should be downloaded from Github and then flashed on MicroSD card using Balena Etcher or similar tool.

Only user entropy is accepted and that is a better option for me because you are not depending on questionable onboard RNG or STM chips that can always have backdoors.
SeedSigner is running on Linux Debian OS and one thing I don't like about that is slow boot time of 45 seconds, but I think this could be fixed in future updates.
You can find several video instructions along with one provided on github and SeedSigner website but I would mention one I recently watched by BTC Sessions.
There is also a good tutorial from BitcoinMagazine with all the parts and installation process:

There are two types of enclosures Orange Pill and Open Pill with original STL files you can 3d print on your own or purchase from other community members.
Some people have even gone step further and they are in process of making their own version of full metal enclosure for SeedSigner.
