Spark
Pay once. Unlock credit somewhere else.
Other credit apps cannot trust a payment that happened somewhere else without a middleman. Spark verifies the payment with Attestcoin, then opens credit on Creditcoin.
I built the Next.js app, Foundry contracts, and the verifier path across Sepolia and Creditcoin testnet.
