(Deployed in Feb. 2023)

A settlement system that guarantees the minimum number of transfers without the need for a treasurer by allowing users to enter their payment details through a single database and platform.

1. Create and share the settlement (via Kakao share, link copy, etc.) to invite participants.
2. Invited users can either add themselves to the settlement or select their names from the existing entries to participate.
3. All participants in the settlement can transparently view payment details, participants, and settlement results.
4. Users enter their own payment details (amount, description, participants, etc.).
5. The settlement algorithm guarantees the minimum number of transfers, resulting in settlement outcomes [(who) → (whom) and (how much)].
