The SeedSigner is project is focused on lowering the cost and complexity of creating and using Bitcoin multi-signature wallets. With a single SeedSigner device, you can manage an infinite number of multi-signature cosigners for an infinite number of multisig wallets. And because SeedSigner doesn’t store seed phrases or private key data after it has been powered off, different parties can even use the same device to manage their long-term Bitcoin savings.
