Awesome.
#SeedSigner

and soon,... I'll release a very nice service (free) that will be fully compatible with seedsigner.
It’s finally here. After a long journey we want thank the open source community for progressing to this point. Last year we asked a Noderunner who did a lot of development work on the Seedsigner plus, if he could create a battery version of the device including smartcard.
It ended up being one of the most amazing team efforts where xmstreet and teamed up to create something that is ultimate for many.

has of course many trade offs in comparison with other signers, but after helping hundreds of people with them we found the following issue to be critical.
- storage of the seed, often done in QR format or plain words. Every time you want to sign you need to get your seedwords or QR code. Apart from that being a physical exposure risk, it also complicates it for many beginners.
“Why so cumbersome” entering the seedkeeper by satochip that we now deliver in metal, for long term durability.
- batteries, the external powersource would often be disconnected and the thread hanging out killed the easy handling of the device.
- + screen, hundreds of people we helped, many complained about the small screen and buttons. Also scanning with sparrow wallet or other coordinators has become a lot easier through this larger screen.

Now the new seedsigner + battery smartcard is here, we’re expecting a bit more development on the shieldsigner fork to become official and to ease the flow even more for noobs.
In the end, 99%+ only needs a single sig with a passphrase.
