## Hardware Wallet Integration

Hardware wallet integration is the process of connecting a physical, air-gapped device to a decentralized application to securely sign transactions. This is a critical security layer for self-custody, as it ensures that private keys never touch an internet-connected device, protecting them from malware and remote attacks.

In the context of trading derivatives, users can interact with protocols directly from their hardware wallet, maintaining full control over their assets even while they are being used as collateral. This integration provides a significant boost to user confidence and is a standard requirement for institutional and serious retail participants.

It effectively bridges the gap between high-level security and the convenience of decentralized finance. By mandating hardware wallet use, protocols can significantly reduce the risk of account compromise.
