This article details how to send funds on your Ledger device's single-key wallet to your multi-key Casa vault via Ledger Live.
If you've previously used your Ledger's single key wallet to protect your funds and are upgrading to Casa's multi-key vault protection (where the Ledger is one of multiple keys in your vault), you're increasing your security by adding redundancy and resiliency.
You would first need to set up either your 3-key or 5-key vault.
After that's set up, you'll want to send the funds from your Ledger wallet to the deposit address you see in your Casa app. This process is essentially the same as you would follow to send funds anywhere else from your Ledger.
1. Open Ledger Live and unlock your Ledger
Open Ledger Live and connect your Ledger to your computer.
Be sure you use the cable that came with your Ledger, or at least one that is rated for data transfer. Some cables are only rated for charging and cannot be used for this.
Enter your Ledger's PIN on the device, using the left and right buttons to cycle through the digits and clicking both buttons to select each number.
2. Open the Casa app
Sign into the Casa app on your mobile device. Select the vault you want to set up (depending on your settings, you may only see one).
Click the "Deposit Funds" (if this is your first deposit) or "Receive" (if you have made previous deposits) button at the bottom.
3. Copy your receive address from the Casa app to Ledger Live
If your computer has a webcam, Ledger Live makes this easy for BTC addresses. Click the "Send" button in the left menu and select the account with your funds. Then click the small picture of a QR code on the right side of the "Recipient address" box.
You may have to allow Ledger Live to access your camera, but once you do, hold your phone with the Casa app QR code up to your computer's webcam to scan the BTC address.
Note that when sending ETH from Ledger Live, or if your computer does not have a webcam, it's best to copy the text of the deposit address from the Casa app, send it to the same computer where you access Ledger Live, and past the address into Ledger Live when sending.
To do this, you'll need to use an app that you can access on both your mobile device and your computer, like Signal, Wire, or Telegram, or email.
Once that's done, click the lavender "Continue" button.
4. Send!
Now that you have the address, set an amount to send in Ledger Live. You may want to send a smaller test transaction before you transfer your whole balance, but once you have confirmed everything is working, toggle "Send Max" on so you don't leave any funds behind!
You can review the fees and set a different option if you want, but "Medium" works fine.
Then click the lavender "Continue" button, then click it again.
Open the relevant app on your Ledger and confirm on the screen of your Ledger that everything looks right, especially the address. If it does, click both buttons to confirm on your Ledger.
The transaction will broadcast and your funds will be on their way to vault protection in the Casa app.
