Polkadot Vault (Parity Signer)

Novasama Technologies GmbH

About this app

Exciting News! 🚀 Polkadot Vault is now owned and maintained by Novasama Technologies! Enjoy the web3 based, non-custodial and encrypted technology while interacting with Polkadot ecosystem.

Polkadot Vault (ex. Parity Signer) turns your Android 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.


– How do I keep my keys secure?

Using Signer is a great way to keep your keys secure! However, that alone won't be enough. Your Signer device can break or get lost. That's why we always recommend having backups, especially paper backups. We are such big fans of paper backups that we even support a special protocol for them called banana-split.

– Should I use Signer?

Signer is optimised for the highest security requirements. If you manage several accounts on several networks, Signer is great for you. If you have little experience with cryptocurrencies but still want good security affordances, you might find the learning curve steep. We strive to make Signer as intuitive as possible; get in touch if you can help us get there!

– How does an offline device communicate with the outside world?

Communication between offline device and the outside world happens through QR codes that are scanned and then, in turn, generated for scanning. There are tried and true cryptographic algorithms that power these QR codes, as well as some smart engineering that make your dedicated device safe to use.

Ratings and reviews

I believe every blockchain projects should create a tool like this for the sake of casual users with no intention or no way to get a actual hardware wallet(there are places in the world where you can't get shipment or have online payments. however, crypto should be universally available) This is one of the best ways to get hardware wallets just by owning two phones. I'd have to thank the Polkadot developers for the ingenuity. Thank u very much!

I downloaded this app, created polkadot wallet and used public key and deposited 2 dot, its not showing any balance 😑. On dot subscan it shows but not in this app wallet

I use the phone in Dark mode, in this mode the QR code barely can be seen. It could be nice to be able of copy the public address without the QR
