You must set up a Bitcoin Vault first to receive bitcoin in your Bitcoin Vault. If you don't have a Bitcoin Vault yet, find our guide on creating a Bitcoin Vault.
Log in to the app, go to Home (bottom left), select Bitcoin Vault, and click the Receive button (QR code symbol).
Copy the displayed receive address, and ensure there are no typos since sending Bitcoin to the wrong address can result in permanent loss of funds. You can use the Generate New button to generate a new address and the Generate Legacy Address button to generate a legacy address.
Send the receiving address (alphanumeric string or QR code) to the person who will transfer bitcoin to your Bitcoin Vault. You can use the Share button to share the address through WhatsApp, Telegram, email and other channels. Once the sender initiates the transfer and the transaction is confirmed on the blockchain, it will be displayed in the funds overview of your Bitcoin Vault.
You can additionally verify the transaction on a blockchain explorer like blockchain.com. Just enter the address or the transaction hash in the search input field and check whether the transaction is verified.
That's it! You've successfully received bitcoin in your Bitcoin Vault.
