Stealth payments are a privacy option when you send crypto from VaultNow. When they are enabled, you can split a single batch across several wallets on the send screen, so the funds don't all leave from one address.
How to use them:
Make sure stealth payments are enabled before you pay.
On the Payments page, select the payments to send and click Pay Selected.
On the send screen, choose stealth payment as the source for a token group, then split the batch across several wallets.
Stealth payments are not available on Solana. Solana payments are custodial and sent as one transaction per payment, so they can't be split.
