Miden wallet extension setup and seed phrase security



Secure Your Miden Wallet A Step-by-Step Setup and Seed Phrase Protection Guide

Install the browser add-on solely from the project's verified distribution channel, never from third-party sources. Before proceeding, confirm the developer's authenticity by checking the listed publisher details against official communications. A single fraudulent copy can compromise all your holdings.


Your 24-word recovery mnemonic constitutes the absolute master key. This string of common words generates every private key and authorizes transactions. Write these terms on durable, non-digital media like stainless steel plates. Storing this data in a text file, cloud service, or screenshot creates permanent, exploitable vulnerabilities.


Isolate the recovery process on a machine free from malware and network connections. Disable internet connectivity before displaying or transcribing the confidential words. This air-gap procedure prevents keyloggers or spyware from capturing the sequence. Treat this operation with the same physical discretion as creating cash.


Establish a multi-signature configuration if the protocol supports it. This mandates several independent approvals for transactions, distributing trust across devices or trusted parties. A single compromised secret phrase then becomes insufficient for asset theft, adding a critical defensive layer.


Validate the receiving address for every transaction using a secondary, trusted method. Malicious software can alter a destination in the interface, redirecting funds irreversibly. Manually compare the full address string against a known-good source before authorizing any transfer.

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. It is displayed on your screen and you must write it down physically at that moment. The extension itself does not store the seed phrase in plain text anywhere you can later access. It's kept encrypted within the extension's local storage, but not in a readable format. If you didn't record it during setup, you will need to create a new wallet and securely note the new phrase.

Is it safe to type my Miden seed phrase on my computer to import the wallet?

Typing your seed phrase on a computer carries risk. Keyloggers or other malware could capture it. The recommended method is to use the extension's "import" function and type the phrase directly into the extension on a clean, trusted device. Never type it into a web browser's general search bar, a text document, or an email. For maximum security, consider using the wallet on a device dedicated to crypto transactions or one with strong, updated antivirus protection.

What happens if I lose my computer? Can I recover my Miden wallet?

Yes, you can recover your wallet if you lose your computer, but only if you have your seed phrase. Your assets are stored on the blockchain, not on the device. On a new computer, install the Miden Wallet first time setup wallet extension and select "Import Wallet" or "Recover Wallet." Enter your 12 or 24-word seed phrase in the exact order. This process gives the new extension access to your blockchain accounts. Without the seed phrase, recovery is typically impossible.

Why does the Miden extension ask for a password if the seed phrase is the main key?

The password you set in the Miden wallet extension serves a different purpose than your seed phrase. The seed phrase is the master key to all your funds and accounts on the blockchain. The local password encrypts the wallet data stored specifically within that browser extension on that device. It prevents someone with physical access to your computer from easily opening the extension and making transactions. However, anyone with your seed phrase can bypass this password entirely from any other device.
