Arcent
What is Arcent? Arcent is the first x402 payment implementation on Arc Network with Pay-on-Success protection. AI agents autonomously discover, negotiate, and pay for API services. No human intervention, no credit cards, no subscriptions. The Problem AI agents can't participate in the economy. They can't have bank accounts, pass KYC, or manage subscriptions. The internet was built for humans, not machines. Our Solution Arcent gives agents a native economy: - Programmable wallets via Circle SDK - HTTP 402 payment protocol (x402) - USDC micropayments on Arc Network - Pay-on-Success — agents only pay for working results - Agents only sign, they never pay gas. The executor wallet covers all network fees. Key Innovation: Atomic Settlement Traditional x402: Agent pays → API called → If API fails, money lost ❌ Arcent: API called first → Response validated → Payment only on success ✅ This protects agents from paying for failed API calls. Technical Architecture - Circle Developer Controlled Wallets for agent custody - Arc Network for sub-second settlement (<1s finality) - Embedded SQL persistence for transaction audit trail - Multi-provider routing with reliability scoring

"Great concept. basically an ai agent shopping setup. demo is also working which is refreshing to see for once!"

"Arcent demonstrates innovative technical architecture with programmable wallets via Circle SDK, HTTP 402 payment protocol (x402), USDC micropayments on Arc Network, and the key innovation of Atomic Settlement that protects agents from paying for failed API calls. The technical stack includes Circle Developer Controlled Wallets, Arc Network for sub-second settlement, embedded SQL persistence, and multi-provider routing with reliability scoring. Key strengths include the revolutionary Pay-on-Success model that reverses traditional payment flow, and the comprehensive agent-native economy design. For improvement, consider implementing more sophisticated reliability scoring algorithms, adding fallback mechanisms for payment failures, expanding the API marketplace with more diverse services, and creating comprehensive monitoring and analytics for agent transaction patterns.

"Arcent is explicitly adding a “pay-on-success / atomic settlement” layer on top of the normal x402 flow. It defines a Result-Validated Payment (Atomic Settlement) where the API is called first, the response is validated, and payment only executes on success."
