Nami Wallet Setup Guide Key Usage Tips and Common Problem Solutions
Install the browser extension directly from the Chrome Web Store or Firefox Add-ons marketplace; this is the only source you should trust for the authentic software. Immediately after adding it, your first action must be to record the 24-word recovery phrase generated during initialization. Write these words in order on physical paper and store them securely; a digital screenshot or text file creates a critical vulnerability.
Before transacting, configure a spending password that is distinct and complex. This password encrypts your private keys locally on your device, so its strength directly protects your funds. For daily use, consider creating a separate, minimal-balance account within the interface to interact with decentralized applications, keeping the majority of your assets in your primary, less-exposed account.
If a dApp connection fails, first check that the extension is unlocked and the correct account is active. Network congestion often causes transaction delays; verify status on a Cardano blockchain explorer like Cardanoscan by pasting your transaction ID. Persistent "transaction failed" errors frequently resolve by increasing the collateral amount, which is reserved for smart contract interactions, to at least 5 ADA.
Always maintain a small amount of ADA, roughly 2-3, in your active account to cover network fees, which average 0.17 ADA for simple transfers. Should the extension interface appear blank or unresponsive, a hard refresh (Ctrl+F5) of your browser page typically restores functionality. For asset visibility issues, manually add the native token or NFT's Policy ID and Asset Name using the "Add Asset" feature within the portfolio section.
Nami Wallet: Setup Guide, Usage Tips and Troubleshooting
Install the browser extension from the official Chrome Web Store or Firefox Add-ons portal, then click its icon and select "Create a wallet." Securely store the 24-word recovery phrase offline–never digitally–as it is the sole key to restoring your funds. Fund your new address by transferring ADA from an exchange; the mainnet automatically appears upon creation.
For smoother interactions, enable the "Always allow DApps to connect" option in the settings to prevent constant pop-ups during decentralized application sessions. Regularly clear your transaction history from the interface to maintain performance, and manually add custom native assets using their full Policy ID and Asset Name when they don't auto-populate. Before signing any smart contract transaction, double-check the exact ADA amount and requested permissions displayed in the confirmation window.
If an asset fails to appear, use the "Add asset" function with its correct identifier. A persistently unresponsive interface often resolves with a browser cache clear or extension reinstall–your funds remain safe with the seed phrase. Transactions stalling at "Pending" typically indicate network congestion; cancel them via the three-dot menu next to the transaction in the activity view to free the locked UTXO.
Installing the Nami Browser Extension and Creating a New Wallet
Navigate directly to the official Chrome Web Store or Firefox Add-ons portal.
Search for the correct utility and verify the publisher before clicking 'Add to Browser'. A confirmation dialog will appear; proceed by selecting 'Add extension'. The icon should materialize in your toolbar upon completion.
Pin the extension for immediate access. Click the new toolbar button to launch the interface. You'll be presented with a clear choice: generate a fresh vault or restore an existing one. Select 'Create' to initiate.
You must now devise a robust password. This passphrase encrypts the local data vault on your machine. Treat it with the same seriousness as a primary email account password; its loss is irrecoverable.
The subsequent screen displays your 24-word secret recovery phrase. This is the master key to your entire portfolio. Write every term on paper in the precise sequence shown. Disconnect your device from the internet while transcribing for heightened security. Digital storage–screenshots, text files, cloud notes–creates unacceptable risk.
Confirm you've recorded the phrase correctly by selecting the words in the exact order when prompted. This step ensures your backup is functional.
Your vault is now active. Immediately send a minimal test transaction, like 2 ADA, to the generated address to confirm everything operates correctly. This verifies send and receive functionality.
Store your physical recovery sheet in a secure, separate location from your primary device. The password and seed phrase serve distinct, non-interchangeable purposes; losing both results in permanent asset forfeiture.
FAQ:
I installed Nami but my balance shows zero, even though I sent ADA to my address. How long does it usually take to appear?
Transactions on the Cardano blockchain require network confirmations. Typically, a transaction is considered complete after 10-20 confirmations, which usually takes 5-10 minutes. First, check the receiving address in your Nami wallet's "Receive" section and verify it matches the one you sent funds to exactly. Then, click the circular arrow icon in the top right corner of the Nami Wallet import wallet extension to manually refresh your balance. If it's been over 30 minutes and the balance still doesn't show, use your wallet address in a Cardano blockchain explorer like Cardanoscan to see if the transaction was successful on the network. A common issue is sending to an address from a different network (like testnet), but Nami uses the mainnet by default.
Can I use my Nami wallet on multiple browsers or devices at the same time?
No, you cannot actively use the same Nami wallet profile across multiple browsers or devices simultaneously. Nami is a browser extension that stores your encrypted keys locally on that specific browser. If you try to set up Nami on a second browser and import your seed phrase, it will create a separate instance. Using both to sign transactions can cause conflicts and errors. For access on another device, you must export your wallet (using the seed phrase) on the new device, which will then make the original browser instance inactive. Think of it as moving the wallet, not copying it. For regular multi-device access, consider a wallet type designed for that, like a mobile wallet paired with Nami for different purposes.
What's the difference between "Assets" and "Tokens" in the Nami interface, and why are some of my NFTs not visible?
In Nami, the "Assets" tab primarily shows Ada and other fungible tokens (like SUNDAE or MIN). The "Tokens" tab is specifically for displaying Non-Fungible Tokens (NFTs). If your NFT isn't visible, there are a few steps to try. First, ensure you are on the correct account in the top dropdown menu if you use multiple accounts. Then, manually refresh the wallet using the circular arrow icon. Most importantly, Nami only displays NFTs from policies it recognizes. If the NFT is from a new or less common policy, you may need to add its Policy ID manually. Go to the "Tokens" tab, click "Add," and paste the exact Policy ID of your NFT collection. After adding it, your NFT should appear after a refresh.
I lost access to the browser where I had Nami installed. How do I recover my wallet?
To recover your wallet, install the Nami extension on a new browser. During setup, select "Import Wallet." You will need your 24-word seed phrase, which was shown and you were prompted to write down securely when you first created the wallet. Enter the words in the exact order, with a single space between each. After entering the phrase, you will set a new password for this new browser installation. This password encrypts the wallet data locally on this device only. If you do not have your seed phrase, recovery is impossible because Nami does not store your keys or phrase. The wallet exists entirely on the blockchain; the seed phrase is your only proof of ownership and means to restore it.
