Project Description

Flex Fuse

Seamlessly Unifying Multi-Chain Subscriptions & Group Expenses

Flex Fuse revolutionizes decentralized finance by solving two critical challenges: managing recurring payments across different blockchains and simplifying group expenses. Built on Kinto's robust infrastructure, our platform enables gasless, automated subscription payments while making shared expenses effortless—regardless of which tokens your group members prefer to use.

Why Flex Fuse Matters

  • Cross-Chain Freedom: Subscribe to services using any token on any chain—we handle the complexities
  • Smart Group Expenses: Split bills, manage shared subscriptions, and track expenses with automatic settlement in each member's preferred token
  • Zero Gas Hassles: Forget about keeping native tokens for gas—our gasless transactions just work
  • Built for Trust: Leveraging Kinto's User-Owned KYC and compliance tools for institutional-grade security

Innovation at Its Core

Flex Fuse isn't just another DeFi tool—it's the missing bridge between fragmented blockchain ecosystems and real-world financial needs. By combining enterprise-grade security with consumer-grade simplicity, we're making multi-chain finance accessible to everyone.

Whether you're a service provider looking to accept cross-chain subscriptions, a group of friends sharing travel expenses, or an individual managing multiple DeFi subscriptions—Flex Fuse is your key to frictionless financial management in the multi-chain future.
