You can transfer your crypto from the Vault to the Wallet or vice versa at any time.
If you want to transfer from your Wallet to your Vault follow this path in your Nuri app:
Wealth > Vault > Receive > tap on the barcode symbol > copy your Vault address
Afterwards, navigate back to Wealth > Wallet > Send > tap the paper plane symbol > paste the Vault address > confirm the transaction
If you want to transfer from your Vault to the Wallet, start these steps with your Wallet instead.
