Zach Herbert explains Foundation’s QuantumLink, a post-quantum Bluetooth bet for hardware wallets

Foundation has introduced QuantumLink, a post-quantum Bluetooth capability for its hardware wallets, with CEO Zach Herbert positioning it as a way to combine wireless connectivity with encryption resistant to future quantum attacks. The feature embeds post-quantum cryptography directly into the signing device rather than relying on a companion app or host machine, extending Foundation's existing Passport hardware wallet line. It matters because hardware wallets have generally traded connectivity for security, and QuantumLink aims to remove that tradeoff as quantum computing timelines grow more concrete. Watch for whether other hardware wallet makers adopt comparable post-quantum schemes and for independent audits of QuantumLink's implementation.
