snaK User Guide

This guide walks you through the steps to connect your MetaMask wallet to the Kadena Snap, install it, approve permissions, and perform basic operations like switching networks and sending $KDA.

💻 Note: The Kadena Snap is only available in the MetaMask browser extension. Users must switch to desktop to interact with the Kadena Snap.

What is snaK?

Kadena Snap is a custom MetaMask Snap that allows users to interact directly with the Kadena blockchain. It enables you to:

• Manage Kadena accounts securely inside MetaMask
• Perform cross-chain transfers across Kadena's 20 chains
• Sign and send transactions using $KDA
• View account balances and activity
• Use gas stations to simplify fees
• Buy KDA through integrated fiat onramps

The Kadena Snap is fully isolated, permissions-based, and built using MetaMask’s secure extensibility model.

Who is this guide for?

This guide is intended for:

• Users who want to manage $KDA from within MetaMask
• Developers building dApps that integrate with the Kadena Snap
• Testers exploring the Kadena Snap functionalities on testnet

No prior knowledge of Kadena or Snaps is required, though basic familiarity with MetaMask is helpful.

What you'll need

Before getting started, make sure you have:

• ✅ MetaMask installed in your browser
• ✅ Access to a Snap-compatible dApp (or localhost test setup)
• ✅ Some $KDA (use the faucet if testing)
• ✅ Basic understanding of MetaMask permissions

💡 You can install the Kadena Snap even without a dApp using the MetaMask Snap Directory.

This guide includes:

• Connecting your MetaMask wallet
• Installing and approving the Kadena Snap

Troubleshooting

Common Issues

• Transactions failing?
  🔹 Verify you have enough KDA for gas
  🔹 Confirm the correct chain is selected
  🔹 Verify you are connected to the correct network

Security Guidelines

⚠️ Important Security Notes

• Your KDA accounts are generated from your MetaMask seed phrase

• The same security practices for ETH apply to your KDA:

  • Never share your recovery phrase
  • Use a hardware wallet for maximum security
  • Be cautious of phishing sites

• Always verify:

  • Transaction details in MetaMask popups
  • Website URLs before connecting
  • Contract addresses when interacting with dApps

🔒 Best Practices

• Regularly review connected sites in MetaMask
• Keep your browser and MetaMask updated
• Consider using a dedicated browser and/or wallet for Kadena Snap
