UnifiedPay

UnifiedPay is a non-custodial USDC payment platform built for creators and other online businesses that need simple, global payments without dealing with chain complexity. The platform treats multiple chains as a single liquidity surface and uses Arc as the primary settlement layer for USDC. From the user’s point of view, payments feel chain-agnostic, even though settlement and coordination happen efficiently on Arc.

UnifiedPay supports use cases like selling digital products, services, courses, or one-off payments. ENS is integrated to replace raw wallet addresses with human-readable names, making payment pages easier to share and safer to use. Payments go directly from the payer’s wallet to the recipient with zero platform fees, and content can be unlocked automatically once a transaction is verified.

UnifiedPay is built as a full-stack Web3 application using Next.js and TypeScript, with Prisma and PostgreSQL used for storing payment data and analytics. USDC is the core payment asset, and Arc acts as the primary settlement and coordination network, allowing the app to abstract liquidity across chains while keeping the user experience simple and consistent.

Circle Gateway is integrated to provide a unified view of USDC balances across supported chains, enabling the platform to reason about capital as a single liquidity surface. ENS is integrated directly using on-chain resolution logic to replace 0x addresses with human-readable names and avatars in the UI. The system remains fully non-custodial, with users always transacting directly from their wallets.
