Secure Your Miden Wallet Extension Setup and Protect Your Seed Phrase

Install the browser add-on solely from the official source, never from third-party links or stores. Verify the developer's details match the project's core team before proceeding with the installation. This single action prevents the majority of credential theft attempts targeting new users.


Your 24-word recovery mnemonic constitutes the absolute master key to your account and assets. The software will display this sequence once; treat its privacy with maximum seriousness. Any digital reproduction–a screenshot, a text file, or a cloud note–creates a permanent vulnerability. Transcribe the words with pen on durable paper, storing this physical copy in a discreet, secure location.


Consider fragmenting this written record across multiple secure deposits, ensuring no single location holds the complete phrase. For heightened protection, encode the sequence within a personal cipher or memory aid, avoiding obvious associations. Never share these words, even with support personnel; legitimate services will never request them.


Before transferring significant value, conduct a full restoration of your account using the paper backup on a clean, trusted device. This verification confirms the accuracy of your record and your ability to regain control without the primary browser tool. Establish this practice as a non-negotiable step in your operational routine.

FAQ:
I installed the Miden wallet extension but can't find my seed phrase. Where is it stored?

After installing the Miden wallet extension, you create a new wallet or import an existing one. The seed phrase is only shown once during the initial wallet creation process. The extension itself does not store or display your full seed phrase again for security reasons. It is not saved in a file you can access later. You must have written it down physically at that moment. If you did not record it, you will need to create a new wallet, secure the new phrase, and transfer any assets from the old wallet if you still have access to it via the extension.

Is it safe to type my seed phrase on my computer when using the Miden extension?

You should only type your seed phrase directly into the Miden extension during the initial import of an existing wallet. This is a necessary step. However, your computer must be free of malware. A keylogger could capture your keystrokes. For maximum security, use a clean, dedicated device for this setup. Never type your seed phrase into any other website, form, or software. The Miden extension will never ask for it again after setup.

What happens if someone gets access to my browser profile? Can they steal my wallet?

Access to your browser profile alone is not enough to steal funds. The Miden wallet extension, like most, requires a password you set to unlock it for sending transactions or viewing sensitive data. This password encrypts the wallet's private keys within the browser's storage. An attacker would need this password. However, if they have full system access, they might install malicious scripts. Use a strong, unique password and enable your computer's screen lock. For large sums, consider a hardware wallet for transaction signing.

Can I use the same seed phrase for my Miden wallet and a wallet on another network, like Ethereum?

Technically, you might be able to import the same 12 or 24-word seed phrase into a wallet application for a different network. This is because many wallets use similar derivation paths. However, this is not recommended. It increases risk. A compromise of one wallet could lead to loss on all networks. Generate a unique seed phrase for your Miden assets. Keep it separate from other blockchain wallets you own. This practice limits damage if one system is breached.

My seed phrase paper got damaged. I still have access via the extension password. What should I do?

This is a critical situation. Your access is temporary, as browser data can be lost. You must create a new, secure wallet within the Miden extension. Write down the new seed phrase on durable material, like metal, and store it safely. Then, immediately transfer all your assets from the old wallet (the one with the damaged phrase) to the new wallet's address. Complete this process while you still have access. After confirming the assets are in the new wallet, you can abandon the old one.

I installed the Miden wallet extension, but I don't see a clear option to export or view my seed phrase again. How can I back it up after the initial setup?

You are correct that the Miden wallet extension prioritizes security by not displaying your seed phrase in plain text within the general interface after setup. To access it for backup, you need to use the specific "Export Seed Phrase" function. Here's how: Open the extension and go to the settings menu, often represented by a gear icon. Look for an option labeled "Security" or "Account." Within that menu, you should find "Export Seed Phrase" or a similar command. You will be required to re-enter your wallet password to proceed. This step confirms your identity. Once verified, the extension will display your full seed phrase on the screen. This is your only opportunity to write it down securely. Use pen and paper, storing it in a physically safe location, away from cameras and digital devices. The wallet does not keep this phrase readily visible to minimize the risk of malware theft.

Is it safe to type my seed phrase on my computer when restoring the Miden wallet, or could keyloggers steal it?

Typing a seed phrase on a computer keyboard carries a real risk if your system is infected with malicious software like a keylogger. Such programs can record every keystroke. The Miden wallet extension setup is designed to reduce this exposure. During the initial creation, the phrase is generated and shown to you without being typed. However, the restoration process requires entering the words. To improve safety, ensure your computer is clean. Use reliable antivirus software and perform the restoration on a system you trust. A more secure method is to use a dedicated, offline device for the initial wallet creation and backup, then only use the extension for transactions. For maximum long-term security, consider using a hardware wallet for managing your assets, as it keeps the seed phrase entirely offline while still allowing you to interact with the Miden extension for operations.
