Desktop Bitcoin Wallet focused on security and privacy. Free and open source. (by sparrowwallet)
This wallet will not rely on a single hw-wallet. Even if a seed / device gets compromised, the money is still safe. The only central point of failure is the software wallet, but auditing software alone is a lot easier than auditing an entire device and all connected software. Sparrow Wallet is obviously open source.
