About
The problem it solves ClosedCred is a payment platform seamlessly integrating Web3 and decentralized finance (DeFi) with Unified Payments Interface (UPI) transactions. The platform enables effortless sending and receiving of cryptocurrencies, including microtransactions comparable to UPI transactions. Utilizing stablecoins such as USDC on the Sui, Aptos and Base network. Users can execute micropayments seamlessly, via UPI's existing QR codes.
How it's made
Challenges we ran into While building ClosedCred, we faced challenges in integrating WebAuthn as an external authenticator for biometric authentication (fingerprints) and integrating Web3Auth with Firebase for account abstraction to add social logins. We developed a custom authentication flow that bridged the gap between Web3Auth and Firebase.
