Is SeedSigner trustworthy?
With a trust score of 7/10 and no currently unresolved incidents, we rate SeedSigner as a solid, trustworthy service. This assessment is based on our trust score system and the incidents documented above – it does not replace doing your own research.
Description
SeedSigner is an open-source project that lets you build your own air-gapped signing device for Bitcoin transactions from cheap, standard hardware (Raspberry Pi Zero, roughly 30-50 euros in materials). Air-gapped means the device never has any network connection whatsoever - no WiFi, no Bluetooth, no USB data connection - communication with wallet software happens exclusively via QR codes. This makes SeedSigner one of the most secure available methods for signing Bitcoin transactions, without the private key ever touching an internet-capable device. The complete software and build instructions are open source and free.
