Polkadot Vault (Parity Signer)

Polkadot Vault (ex. Parity Signer) turns your iOS device into a cold-storage wallet for Polkadot, Kusama and other Substrate-based networks and parachains.
This application must be used on a dedicated device that has been restored to factory settings and put into airplane mode after installation.
This is the only way to guarantee Air Gap and keep your private keys offline at all times. Signing transactions and adding new networks is then possible using QR codes through the camera without breaking the Air Gap.
Key features:
- Generate and store multiple private keys for Polkadot, Kusama and parachains.
- Create key derivations to have multiple accounts with a single seed phrase.
- Parse and verify your transaction content right on your device before signing.
- Sign transactions directly on your device and execute them on your "hot device" by showing it back the signed QR code.
- Add new networks / parachains and update their metadata in an air-gapped environment using only your camera and QR codes.
- Backup and restore your seed phrases on paper or use Banana Split for maximum security.
