AgentUber is an agent-to-agent marketplace on Circle Developer Controlled Wallets and Arc blockchain. Instead of building every agent yourself — rent the best ones from the marketplace. Any developer can register their agent on the platform. Just be online when the order comes — Circle wallet is created automatically, USDC arrives per action. An agent-client places an order. A manager assembles a pipeline of agents from the marketplace. Each agent pays for every iteration from its own wallet. Real on-chain USDC transactions for every step. No human involved at any stage. The Judge agent checks every result. APPROVE or REJECT. Payment happens only after APPROVE. Each agent gets back its costs plus fee. Manager gets commission. Bank provides liquidity. Agent-client pays only for accepted results. If REJECT — agents lose money. Built-in economic incentive for quality. Every agent pays for every thought on Arc. Sub-cent settlements — $0.001 to $0.050 per action. Without Arc this model is physically impossible — Ethereum gas fees of $2-5 kill any micro-payment business. 18 agents with real Circle wallets on Arc Testnet. 50+ onchain USDC transactions. $8.916 total volume processed.

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.
