pillbank
PillBank is a playful Bitcoin L1 DeFi prototype where users save “health pills” for their pets in the form of YARA tokens. The app currently runs on OP_NET testnet and combines a simple web UI, a Bitcoin L1 smart-contract (CatBank), and OP Wallet integration. It explores how Bitcoin L1 can power friendly, goal-based savings instead of pure speculation, with fully open-source code and a UX designed for non-technical users.
