Polkadot Vault (Parity Signer)

iOS Universel / Finance

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.

Quoi de neuf dans la dernière version ?

Multi-chain derivation paths, Polkadot EVM networks and more are here in Polkadot Vault v7.1!

* Added support for multi-chain derivation paths – when you pair a Polkadot Vault wallet with a multi-chain wallet, such as Nova Wallet, you can now freely transact on all supported chains without needing to add the derivation path for each network.

* Metadata proofs to sign transactions without adding each network – you can now sign transactions on all supported networks without adding each network to your Polkadot Vault.

* Improved support for EVM networks – you can now sign transactions and import/export dynamic derivations on Polkadot EVM networks such as Mythos, Moonbeam, and Moonriver.

* Added support for signing arbitrary messages – you can now sign arbitrary messages that, for example, allow you to leave comments on Polkassembly or Subsquare from your Polkadot Vault wallet.

* Added support for metadata proofs for dynamic derivations and bulk transactions
