Arc: The USDC Liquidity Hub
UnifiedPay treats multiple blockchains as a single USDC liquidity surface
How It Works
- Users pay from Ethereum, Polygon, Avalanche, or Base — USDC lives where they already have it
- Arc serves as the settlement layer — All creator payments settle on Arc Network
- Balances unified via Circle Gateway — See total USDC across all chains in one view
- Chain complexity abstracted — Users see one unified USDC balance, not fragmented liquidity
Why This Matters
- For Creators: Receive all payments on Arc (low fees ~$0.01, fast finality <1s)
- For Customers: Pay from wherever your USDC lives — no forced bridging required
- For the Ecosystem: Arc becomes the canonical settlement layer for multi-chain USDC commerce
Capital Efficiency: No manual bridging. No fragmented liquidity. Arc acts as the hub while users maintain assets on their preferred chains.
Technical Implementation: UnifiedPay integrates Circle Gateway APIs to aggregate USDC balances across Ethereum, Polygon, Avalanche, and Base testnets. All payment settlements occur on Arc Network, establishing it as the primary liquidity hub for creator payments.

0x742d35Cc6634C0532925a3b844Bc9e7595f0aEb0https://unifiedpay.com/pay/alice.ethENS makes crypto payments feel like sending money to @username. Improved UX, better safety (verify names vs hex), and stronger web3 identity.
Technical Implementation: UnifiedPay integrates ENS resolution via ethers.js and Ethereum mainnet providers. The ENSAddress component dynamically resolves names to addresses, fetches ENS avatars from IPFS/HTTP, and performs reverse resolution for transaction senders. ENS data is cached for performance.

Technical Architecture
How Arc + ENS power chain-abstracted USDC payments
User Wallet (Any Chain)
Customers hold USDC on Ethereum Sepolia, Polygon Amoy, Avalanche Fuji, or Base Sepolia
Circle Gateway (Balance Aggregation)
Circle Gateway API aggregates USDC balances across all chains
→ Read-only balance aggregation (no custody)
Arc Network (Settlement Layer)
All creator payments settle on Arc Network
→ Fast finality (<1 second)
→ Acts as the USDC liquidity hub for multi-chain commerce
ENS Resolution (Human-Readable Identity)
ENS provides human-readable addresses throughout the platform
creator.eth → 0x address→ Displays sender ENS names in payment history
→ Shows ENS avatars from IPFS/HTTP records
Backend Verification (Payment Monitoring)
UnifiedPay backend monitors Arc Network for incoming payments
→ Stores payment records in PostgreSQL
→ Unlocks content access after verification
Result: Users experience a unified USDC payment system that abstracts chain complexity while maintaining non-custodial control. Arc serves as the liquidity hub, and ENS provides human-readable identity.
