Problem
Every year, exam paper leaks in government and competitive exams (like NEET) destroy trust, waste crores of rupees, and harm students. It is extremely difficult to trace who printed and leaked the paper. SecurePrint Ledger solves this by making every printed copy traceable to the exact operator, center, and batch.
How UGF was used
I used UGF to make all critical actions completely gasless on Base Sepolia using Mock USD. The 6 main flows are: Admin creates print job Admin assigns job to operator Operator accepts job Operator submits print acknowledgment Public reports leak Bounty reward claim All actions are executed via UGF without users needing ETH.
