Thanks for the feedback! And yes to both. Spending limits and transaction notifications are on the roadmap. Right now parents can already see their child's full transaction history from their own account, and every chore payout needs parent approval before sats move. You also choose the wallet mode per child — earn-only (they can only receive sats from you and send them back) or full self-custody where they manage their own keys. You can start with earn-only and upgrade when they're ready. We're adding more granular controls on top — per-child spending limits, feature toggles, and the ability to restrict specific wallet functions. The goal is to give parents full control over how much responsibility they hand over and when.
