The industry standard for safely securing cryptocurrencies is hardware wallets, specialized devices that provide full isolation between your computer and your private keys.
If you want to use the Avalanche address you created earlier, you need to use the restore from recovery phrase procedure using mnemonic phrase you got from the Avalanche wallet. If you're setting up a fresh address, just follow regular set up as new device procedure.
The Avalanche Ledger wallet app is currently available via Ledger Live in Experimental Mode.
First, you’ll need to install Ledger Live. There’s a download for MacOS, Windows and Linux as well as iOS and Android.
Next, fire up Ledger Live and click the “Settings” button.
Once in settings then go to the “Experimental features” tab.
Scroll down to the “Developer mode” toggle switch, and enable it.
Now with “Developer mode” enabled, you can go to the “Manager” tab and search for “Avalanche”. Confirm that the Avalanche app is v0.2.1, and click the “Install” button.
You can confirm the installation was successful by going to the “Apps installed” tab where you should see Avalanche v0.2.1.
Once you have the Avalanche app installed then you’re able to interact with the Avalanche Wallet via the Ledger. This includes sending AVAX, tokens, NFTs, cross-chain swaps between the X-Chain<->P-Chain as well as staking tokens.
First, to access the wallet, plug in the Ledger to your computer and if needed, enter your pin.
Next, if you see the text “Pending Ledger review” then click both buttons on the top of the device to skip that screen.
Lastly, you should land on the “Avalanche” app screen where you can confirm that the app is version 0.2.1.
After you confirm that the Avalanche app is running then on the wallet homepage click the “Access Wallet” button.
On the subsequent “How do you want to access your wallet?”, click the “Ledger” button.
You’ll now be prompted to confirm on your Ledger device. Click right button through the prompts on the device and on the last screen confirm by pressing both buttons.
If successful you will be signed into the wallet and any previous balances will be displayed.
To transfer funds, go to the “Send” tab and paste an X-Address into the “To Address” field. Set an amount and optionally set a memo. Press "Confirm" and then the “Send Transaction” button.
You’ll be prompted to confirm the action on your Ledger. Check that the hash which is displayed in the web wallet matches what is displayed on your Ledger. If everything matches then confirm by pressing both buttons on the last screen to send the transaction.
You can click the icon to refresh your balance and you should see it decrease per the amount which you just sent and the transaction fee.
In the right-hand column, you will see your latest transaction. Clicking the magnifying glass icon will open the transaction in our explorer.
Finally, you should be able to see the transaction details in our explorer. This lists everything about the transaction, including transaction ID, status, when the transaction occurred, and all of the information regarding inputs and outputs.
