1. Introduction​

Zazen is a MetaMask Snap that securely stores your validator node cloud access keys within MetaMask. By integrating with the ZenChain Node Station dApp, Zazen simplifies the process of deploying and accessing your validator nodes without the need for external password managers or manual key handling.

2. Installation​

Prerequisites:

  • MetaMask: Installed in your browser.
  • MetaMask Snaps: Enabled in your MetaMask settings.
  • ZenChain Station dApp: Accessible at https://node.zenchain.io.

Video Instructions:

Steps:

  1. Navigate to ZenChain Station: Go to https://node.zenchain.io.
  2. Connect Wallet: Click on the "Connect Wallet" button in the upper right corner.
  3. Install Zazen Snap: The dApp will prompt you to install the Zazen Snap if it's not already installed.
  4. Grant Permissions: Approve the installation and grant the snap_manageState permission when prompted by MetaMask.
  5. Confirmation: Once installed, no further action is needed. Zazen will operate in the background.

3. Using Zazen with ZenChain Station dApp​

  • Submit Cloud Access Keys: When setting up your node in the ZenChain Station dApp, you will be asked to input your cloud access keys (e.g., OnFinality keys).
  • Automatic Storage: Upon submission, Zazen automatically encrypts and stores your keys within MetaMask.
  • Future Access: The next time you use the dApp, Zazen will retrieve your keys automatically, so you won't need to re-enter them.
  • No Direct Interaction Required: Users do not need to interact with Zazen directly or use any JSON-RPC methods.

4. Technical and Security Considerations​

  • Encrypted Storage: Your cloud access keys are encrypted and securely stored within MetaMask.
  • Accessibility: The encrypted storage is only accessible when MetaMask is unlocked.
  • Permissions: Zazen operates with the snap_manageState permission, which you grant during installation.
  • Data Privacy: Your keys remain on your device and are not transmitted to any external servers other than your cloud provider when deploying nodes.

5. Troubleshooting​

When using Zazen Snap and the MetaMask Snaps platform, you might encounter issues either with the platform itself or specifically with the Zazen Snap. Below are some troubleshooting steps to help you resolve common problems.

Distinguishing Between Platform and Snap Issues
