Feature Request: “Reserved Funds” or “Locked Balance”

I’m using TerraWallet to create a layaway/pre-order system where customers save up for specific products. Currently, there’s a critical limitation: when a customer makes a payment toward their layaway item, that amount is added to their general wallet balance. They can then immediately use those funds to purchase other items. Feature Request: Please add a dual-balance system with “reserved/locked funds” functionality, similar to how bank accounts work. We need a Total Balance (all funds deposited) and an Available Balance (funds not locked for specific purposes). Admins should be able to lock a portion of a user’s wallet balance against a specific order. Customers should only be able to spend or withdraw from their Available Balance, not from locked funds.
