Using KeepKey with dApps

Understanding EIP-6963

The KeepKey browser extension implements EIP-6963 (Multi Injected Provider Discovery), a standard that enables dApps to discover and interact with multiple wallet providers simultaneously. This modern approach uses window events to announce injected wallet providers, making the connection process more seamless and secure.

Example: Using KeepKey with Uniswap

The extension integrates smoothly with popular dApps like Uniswap, allowing you to:

• Connect your KeepKey wallet directly
• Sign transactions securely
• Manage your DeFi positions
• View real-time balance updates

Troubleshooting

Common Challenges and Solutions

dApp Compatibility Issues

Many dApps haven’t implemented EIP-6963 yet, which can cause connection issues. Here’s how to handle this:

1. If you don’t see keepkey-client:

   • Disable MetaMask and other wallet extensions
   • Disable apps that mask MetaMask (like Rabby or Exodus)
   • Enable only the KeepKey client
   • Refresh the dApp

2. Additional Verification Steps:

   • Ensure KeepKey is open on the home screen
   • Verify balances are displaying correctly
   • Check that the extension is properly connected

MetaMask Masking Explained

The extension currently uses MetaMask masking to ensure compatibility with older dApps. While this solution isn’t ideal, it’s necessary for broader compatibility until more platforms adopt EIP-6963.

Alternative Solution

If you’re still experiencing issues, Wallet-Connect provides a reliable alternative method for connecting your KeepKey to dApps.

Future Development

The KeepKey team is actively working on:

• Expanding browser support (Brave, Firefox, Arc)
• Improving dApp compatibility
• Enhancing the user interface
• Adding new features based on community feedback

Conclusion

The KeepKey browser extension represents a significant step forward in hardware wallet integration with Web3 applications. While there are some current limitations due to evolving standards, the team is committed to providing regular updates and improvements to ensure the best possible user experience.
