Every deployed AI agent is a liability. When one goes wrong, companies face slow, opaque claims processes and significant reputational damage. AgentIndemnity solves this by instrumenting AI agents with a USDC-backed performance bond on Arc. This is not insurance; it is a programmable accountability layer. Each outbound agent action incurs a sub-cent usage charge authorized per request through Circle Gateway Nanopayments (x402). A configurable anomaly detector monitors every reply; when a jailbreak, refusal abuse, or policy violation is detected, the smart contract automatically slashes the bond and transfers USDC directly to the victim wallet, on-chain, in real time. The system routes requests intelligently: Gemini 3 Flash handles classification, orchestration, and function calling; Featherless specialist models cover cost-efficient domain-specific inference (general, technical, legal/risk); and Gemini 3 Pro handles ambiguous or high-stakes fallback reasoning. Pricing scales by route, from $0.001 for a general query to $0.01 for a deep reasoning call, demonstrating why sub-cent economics are only viable on Arc and not on traditional payment rails or raw L1 chains. Developers integrate with a single middleware call. A three-view dashboard (Developer, Compliance Officer, Customer) gives live visibility into bond balance, routing decisions, payment status, and slash events, all streamed in real time via WebSocket.

In this hybrid hackathon powered by Arc and Circle, developers will build the next generation of Agentic economic applications using Circle’s Nanopayments infrastructure with settlement on Arc in USDC. For the first time, high-frequency, usage-based transactions between users, APIs, and AI agents can operate without gas overhead eroding margin. Arc provides stablecoin-native settlement with predictable, dollar-denominated USDC fees and deterministic, sub-second finality — enabling real-time coordination and economically viable per-action pricing at scale. 📅 April 20 – 26, 2026 • Apr 20 – 25 (Online): Submit projects by Apr 25. • Apr 25 (On-site Build – SF, CA): Teams refine projects. • Apr 26 (On-site Demos & Awards – SF, CA): Live pitches & winners announced.
