Product story
The prototype models squad contributions and match-day expenses, then turns role-based approvals into exact payment capabilities with policy simulation and safe no-broadcast signing.
My contribution: Designed and built the treasury product, Captain/Treasurer approval model, guarded payment-intent flow, WDK proof surface, and automated verification.
What the public build demonstrates
- A football-specific treasury surface tracks contributions, balance, pending dues, and match-day expenses.
- Captain and Treasurer approvals create an exact, one-time payment intent before execution can proceed.
- WDK policy evaluation and no-broadcast signing provide integration proof while the browser displays sanitized evidence.
Scope and accuracy
CupTreasury is a self-custodial integration prototype. The portfolio labels policy simulation and no-broadcast signing clearly rather than implying live treasury custody or broadcast execution.
