Recover Nami Wallet wallet setup guide usage tips and troubleshooting



Nami Wallet Setup Guide Key Usage Tips and Common Problem Solutions

Download the browser extension only from the official Chrome Web Store or Firefox Add-ons page. Verify the developer name matches the project's official team before adding it to your browser.

Initial Configuration Steps

After installation, click the extension icon. Select "Create a new wallet." You will receive a 24-word recovery phrase. Write each word in the exact order on physical paper. Never store this phrase digitally. Confirm the phrase by selecting the words in sequence when prompted.


Set a spending password. This password encrypts your data locally; losing it requires restoration via your recovery phrase.

Connecting to dApps

Visit a Cardano decentralized application. Click its "Connect" button. A pop-up will appear listing detected extensions. Choose your installed manager. Authorize the connection for the session. You can revoke access anytime within the extension's settings under "Connected Sites."

Managing Multiple Addresses

Generate separate receiving addresses for better transaction tracking. Navigate to the "Receive" section. Click "Generate new address." Label each address (e.g., "Staking Rewards," "NFT Sales") for clear internal accounting.

Resolving Common Problems
Transaction Failures

Failed transactions often result from insufficient ADA for network fees. Ensure a minimum of ~1.2 ADA remains in your balance beyond the transaction amount. Check the transaction's size; large batches of assets may exceed limits, requiring splitting into smaller operations.

Balance Not Displaying

If assets appear missing, manually sync with the blockchain. Click the circular arrow icon in the extension. Switch your network (from Mainnet to Preprod or vice versa) and switch back. Clear your browser cache and restart the browser if the issue persists.

Extension Unresponsive

Disable then re-enable the extension in your browser's management menu.
Remove and re-add the extension (you will need your 24-word phrase to restore).
Ensure your browser is updated to its latest version.


For persistent network errors, verify your device's clock is set to the correct time and timezone. Incorrect system time disrupts communication with blockchain nodes.

Nami Wallet Setup Guide, Usage Tips and Troubleshooting

Install the browser extension only from the official Chrome Web Store or Firefox Add-ons website to avoid malicious clones.


Write your 15 to 24-word seed phrase on paper, store it physically, and never save it digitally. This phrase is the absolute key to your funds; losing it means permanent loss.


Always maintain a minimum of ~5 ADA in your account. This covers network fees for transactions and prevents failed operations from insufficient collateral.


If an NFT or token doesn't appear, manually add its Policy ID via the 'Assets' tab. Check Cardanoscan to verify the asset's existence and correct ID before adding.


Persistent connection failures often stem from conflicting extensions. Disable other Cardano tools or ad blockers, refresh the page, and try reconnecting the interface.


For transaction errors, check the current network congestion on a Cardano explorer. High traffic increases fees and delays; resubmit later with a slightly higher fee parameter.


Regularly clear your browser's cache and ensure the extension is updated. Sync its state by clicking the circular arrow icon on its main screen to reflect the latest blockchain data.

FAQ:
I downloaded Nami but the extension icon is gray and won't open. What should I do?

First, check if your browser has fully installed the extension. Sometimes a restart of the browser is needed. If it's still gray, ensure you are not in a private/incognito window, as extensions often default to being disabled there. You'll need to manually enable Nami for private windows in your browser's extension settings. Another common fix is to pin the Nami extension to your browser's toolbar. Right-click on the extension area and select "Pin" for Nami. This often makes it accessible.

Can I use my Nami wallet on multiple devices, like my laptop and phone?

Nami is a browser extension wallet, designed primarily for desktop browsers like Chrome, Brave, or Firefox. You cannot directly install it on a mobile phone. Your wallet exists where your seed phrase is stored. If you set up Nami on your laptop, you can use the same 24-word seed phrase to restore the wallet into a separate Nami installation on a different desktop computer. However, for mobile use, you would need a compatible mobile wallet that supports the same seed phrase format and network, and then restore using those words. Managing the same seed phrase on multiple active devices requires caution to avoid conflicts.

What's the difference between a "read-only" wallet and my normal one in Nami?

A read-only wallet allows you to view the balance and transaction history of a specific Cardano address, but you cannot send assets from it or interact with dApps. It's useful for tracking a portfolio or a treasury address without any risk of spending. You create it by selecting "Add Read-Only Wallet" and pasting a valid Cardano address. Your normal, functional wallet requires your seed phrase or a hardware device to sign transactions. The two types are kept separate within the extension so you can switch between viewing a public address and managing your private funds.

I tried to swap tokens on a DEX but the transaction failed. I lost ADA for the fee, but my swap didn't happen. Why?

Failed transactions on Cardano still incur network fees. This is normal. The most frequent causes are slippage and price fluctuation. If the token's price changes between the time you submit and the time the transaction processes, it may fail. Try increasing your slippage tolerance in the DEX's settings. Another reason could be insufficient ADA in your wallet to cover both the fee and the minimum ADA required to hold the new tokens. Always ensure you have extra ADA beyond just the swap amount. Check the DEX or platform for a transaction error log; it often provides a specific reason for the failure.
