Once you have bitcoin in your Casa App's multisig wallet, you can easily send to any bitcoin address, anytime.
When you’re ready to send bitcoin using Casa App, start by swiping up from the bottom of your main screen to access your wallet. If you have multiple wallets, you'll first need to select the individual wallet you need to spend from.
Next, tap "Send."
Enter the amount you want to send, then tap "Next; Choose Recipient" and either scan or paste a BTC address to send to, then swipe up to confirm:
Once you swipe up to confirm, you will now sign the transaction with your keys. For those using 2/3 Basic Multisig, you would normally apply signatures from your mobile device and your hardware device.
For those using a 3/5 Keyshield, you'll need to apply 3 signatures from any of the 5 keys in your keyset.
The mobile key signature is added automatically. To add you second signature, tap the key you want to sign with, then tap "Send email to connect device."
Follow the steps in your email to sign with your hardware device. Once it's signed, the app will allow you to send the transaction:
Once you give it the final approval, your transaction will be broadcast to the Bitcoin network and confirmed soon.
