Flowcard

FlowCard is a programmable salary card platform that transforms payroll into an autonomous onchain system. Built on USDC, ERC-7710 delegations, MetaMask Smart Accounts, x402 paid APIs, and AI agents, it enables employers to issue salary cards with a single signature and automate recurring payroll without requiring further manual intervention.

Once a card is created, an agent network continuously manages payroll cycles by purchasing verified exchange-rate data through x402-paid APIs, generating secure redelegations, and executing onchain salary top-ups. Employees receive funds directly into their card balance and can spend them through a familiar payment experience, where recipient addresses are automatically checked for fraud risks before transactions are approved.

FlowCard also incorporates AI-powered financial insights through Mistral, automatically generating spending reports, category breakdowns, anomaly detection, and recommendations after each payroll cycle. All user actions are secured through MetaMask signatures, ensuring that private keys never leave the user's wallet while maintaining full transparency and auditability onchain.

The project demonstrates how smart accounts, delegated permissions, autonomous agents, paid APIs, and AI can work together to create a secure, self-driving payroll infrastructure that reduces operational overhead while improving transparency, safety, and user experience.
