Hardware Wallets

Introduction

Nova Wallet supports two of the most popular hardware wallets in the Polkadot ecosystem – Parity Signer and Ledger.
Parity Signer is a cold storage hardware wallet solution developed by Parity Technologies whereby a user can convert a mobile device into a secure, offline cold storage device. When used in conjunction with Nova Wallet, users can have access to top level security, as well as an intuitive, user-friendly interface.
Nova Wallet has support for the Ledger Nano X hardware wallet. The Ledger Nano X connects to your mobile device via bluetooth and has a large screen for ease of use.
