Payflow

PayFlow is an onchain subscription manager that helps users easily view, control, and manage recurring payments. Using CDP Embedded Wallets for instant, seedless onboarding, PayFlow gives users a simple dashboard of all their active onchain subscriptions. With x402, users can set rules such as autopay, cancellation, or refund triggers, ensuring they stay in control of every recurring charge. PayFlow prevents silent renewals and unused subscriptions, helping users save money and manage Web3 payments with confidence.

PayFlow is built with CDP Embedded Wallets, x402 on Polygon, and Subsquid (SQD) for on-chain intelligence. CDP Embedded Wallets provide instant, seedless onboarding and user-approved budget limits. Using x402 on Polygon, PayFlow executes programmable payments—autopay, cancellations, and refunds—based on those budgets. Subsquid’s Portal API and Pipes SDK index merchant activity in real time, enabling risk checks before each payment and flagging patterns like high-frequency charges or suspicious addresses. The frontend uses React + viem, with a lightweight Fastify backend managing allowances, tracking spending, and orchestrating x402 flows. Payments are executed from an agent wallet with user-authorized budgets, removing gas and signing friction for end users.
