Paynvest

Paynvest is a DCA investing platform for Ethereum that combines the Papaya Subscriptions Protocol and the 1inch Limit Order Protocol. Users deposit USDC once, configure how much and how often they want to invest (e.g., $10 everyday), and the system takes care of the rest. Papaya handles onchain streaming of funds from the user’s balance on a recurring basis, and each transfer is automatically executed as a limit order through 1inch to buy ETH. This setup allows users to reduce volatility risk, avoid emotional timing decisions, and build a position in ETH over time. All purchases, balances, and portfolio value are visible in a simple and elegant dashboard, with full transparency on every onchain transaction.

The app is powered by the Papaya Subscriptions Protocol for managing recurring onchain transfers and the 1inch Limit Order Protocol for executing ETH purchases. We built custom smart contracts to link Papaya and 1inch in a trustless flow. The frontend is written in React (Next.js), styled with Tailwind CSS and shadcn/ui, and deployed on Vercel. Wallet connection is handled via Reown AppKit. For each active DCA strategy, Papaya streams funds to the contract, which then triggers a limit order on 1inch. We also track portfolio performance and onchain transaction history. Everything is non-custodial, permissionless, and composable with other DeFi tools.
