Security is central — here's how the extension keeps your assets safe.
Local encryption: Your seed phrase and private keys are encrypted locally with a password you set.
Permission prompts: dApps must request explicit permission to connect; transaction signing requires confirmation.
Open-source components: Critical parts of the extension are auditable and reviewed by the community.
No telemetry: Minimal analytics and no personal data collection unless explicitly enabled.
Get started in three simple steps.
Visit the Chrome Web Store or Firefox Add-ons and click "Add to Browser".
Create a new wallet or import an existing seed phrase. Choose a strong password for local encryption.
Optionally connect a hardware wallet and review network settings.
Tip: Back up your recovery phrase in a secure offline place — it’s the only way to restore access if your device is lost.
The extension injects a Web3 provider into pages you visit, allowing dApps to request account addresses and transaction signatures. When an app asks to connect, you'll see a permission dialog showing the requesting origin and the accounts the app can access. All signing operations happen locally — the extension shows transaction details so you can review gas, amounts, and destination addresses before approving.
