Description
VaultPay makes onchain saving feel simple and familiar. Instead of presenting users with a complex DeFi dashboard, VaultPay gives them a clean fintech experience where they can connect a wallet, join the protocol, create savings vaults for personal goals, add funds, view maturity status, and withdraw when ready.
Each saving vault has a name, amount, maturity date, safe mode setting, and early withdrawal penalty. If a user withdraws before maturity, the app clearly shows that a penalty may apply. The smart contract handles the savings logic on Arbitrum, while the frontend focuses on clarity, trust, and ease of use.
VaultPay is powered by an Arbitrum Stylus smart contract written in Rust, showing how developers can build user-friendly financial products with familiar Web2-style UX and transparent onchain enforcement.
