Overview
Amplop is an allowance wallet for Indonesian students studying far from home. A parent pays rupiah once; the money arrives as digital dollars (AUSD on Monad testnet), splits into five envelopes, and is released one weekly share at a time. A card pays from the envelope that matches the kind of shop, and the Emergency envelope opens when a trusted person approves, or by itself after 48 hours.
Open the app at the app's address (set when it is deployed), or follow the five-minute Try it guide.
What is new
Section titled “What is new”- Money split into envelopes on arrival.
- Weekly release.
- The contract itself deciding each card payment.
- A trusted person who can open Emergency but cannot block it.
- A parent who sees totals, not shops.
In short, the parent sees totals, not shops: each envelope’s total and a few alerts, never where the money was spent.
