Securing Your Assets with Parity Vault

In today’s rapidly changing world of cryptocurrencies and blockchain, the security of digital assets is critical. Wallets, which bridge the gap between users and their funds, are essential to this security framework. While many wallets offer a range of features, sometimes less is more. Focusing on a single core function can actually boost security. That’s where the Parity Wallet stands out — it has one main job: to protect your assets. This article provides a detailed guide on how to best secure your cryptocurrency using a security-centric approach.

  1. Hardware Preparations:

    • Acquire a Google Pixel 4a or a subsequent model. Pixel devices with GrapheneOS have been designed with an array of security features, including hardware-backed keystores and a hardened memory allocator.
    • On your Pixel device, install GrapheneOS. It’s an open-source mobile OS optimized for security and privacy, with features like the hardened malloc implementation and extensive hardening of the base system and bundled apps.
  2. Parity Wallet Deployment:

    • Utilizing the sandboxed environment of the Google Play Store on GrapheneOS, download the Parity Wallet. This isolation ensures minimal risk to the primary OS.
    • Remember, the wallet’s primary function is security, which requires a stripped-down, laser-focused environment.
  3. Communication Lockdown:

    • Enable airplane mode, severing all communication, including Wi-Fi, Bluetooth, and cellular.
    • It’s imperative to maintain this state. In the context of security, an air-gapped device introduces barriers to potential external threats.
  4. Configuration of the Parity Wallet:

    • Initialize the Parity Wallet application.
    • Initiate the process to create a new wallet. This encrypted digital envelope will act as the guardian of your assets.
    • Backup the wallet seed phrase in a secure location. The correct way of updating air-gapped wallet requires full reinstallation of GrapheneOS and Parity Wallet. Therefore, it’s crucial to have a secure backup of the seed phrase.
  5. Integration with Polkadot.js:

    • On a separate secure computing environment, navigate to
    • Create a pure proxy account for your Parity Wallet. As elucidated in the Polkadot documentation, proxies act as a secondary protective layer, enabling certain functionalities without exposing the primary account’s assets. This modular security approach minimizes risk by segregating roles and responsibilities. The pure proxy also enables selling the account to new owner in secure manner.
  6. Maintenance and Updating Protocols:

    • Just as in the world of software engineering, version control and updates are crucial to the health of a digital wallet.
    • Metadata of the wallet can be updated in air-gapped manner by reading QR code with the Parity Wallet app here.
    • When considering a wallet upgrade, a clean install approach is recommended. Purging the previous version and deploying a fresh installation eliminates residues and potential vulnerabilities. Detailed procedures for this can be found within the official Parity documentation.

In summation, the fusion of state-of-the-art hardware (Pixel devices with GrapheneOS) and meticulously crafted software (Parity Wallet) provides a foundation of unparalleled security for your digital assets. By emphasizing air-gapped operations, singular functionality, and rigorous update protocols, users are poised to harness maximum security for their Polkadot assets. Adapting to these practices not only enhances security but also instills confidence in users, assuring them that their investments are guarded with the utmost precision and care. As the decentralized space continues its exponential growth, these methodologies will serve as benchmarks for secure digital asset management, steering the community towards safer horizons.
