BuyNowPayNever is a RealFi application where users deposit funds into on-chain yield vaults and use the generated yield — not their principal — to pay for subscriptions and digital services like Netfl
BuyNowPayNever enables users to live off yield instead of selling assets. Users deposit stablecoins into Mantle-based vaults that generate yield, which is programmatically routed to pay for subscriptions and recurring digital expenses while the original deposit remains untouched.
The system uses on-chain vaults, yield routing contracts, and automated spend authorization. In production, vaults can integrate compliant RWA-backed strategies such as treasury funds or invoice financing, making real-world cash flows directly usable for everyday payments.
Built on Mantle for low fees, high throughput, and EVM compatibility, BuyNowPayNever is designed to scale consumer financial use cases on-chain while remaining composable with DeFi and RWA protocols.
During the hackathon we built a functional MVP on Mantle testnet including: Smart contracts for deposits, yield simulation, and yield routing On-chain accounting of principal, accrued yield, and spendable balance Spend authorization flow triggered by subscription actions Frontend dashboard showing deposits, yield growth, and payments Wallet integration and live contract interaction on Mantle testnet The demo shows end-to-end flow: deposit → yield accrues → subscription paid from yield while principal remains unchanged.
Bootstrapped and self-funded. Currently building MVP and validating product-market fit. Open to grants, incubation programs, and strategic ecosystem partnerships for further development and compliance integrations.
