TTM Agent Market is a judge-facing marketplace for paid machine work. Instead of charging flat subscriptions for vague AI access, we price concrete artifacts such as delivery packets, review bundles, and market intelligence briefs in USDC, then unlock those artifacts only after payment settlement is verified on Arc Testnet. The workflow is explicit: ask the Gemini agent to buy an artifact, create a payment intent, route funds from a Circle developer-controlled wallet to the treasury wallet, verify the transaction receipt, advance the review lifecycle, and deliver the artifact. We chose Arc + Circle because sub-cent agent commerce breaks on every other stack we evaluated. Our typical ticket is 0.001 USDC. On Ethereum L1 that would be immediately destroyed by gas. Generic L2s get closer, but the economics remain fragile and fee denomination stays volatile. Arc preserves sub-cent viability with fast settlement, while Circle gives us dev-controlled wallets, USDC-native pricing, and the operational model needed to coordinate multiple agent identities safely. This is not a mock pitch. The demo exposes a public deployment, a public summary endpoint, proof from a 63-transaction Arc Testnet batch recorded on April 23, 2026, and a live Gemini agent flow. That batch moved 0.063 USDC total at 0.001 USDC per action, reached 100% success, and sustained 17.7 transactions per minute. Judges can watch Gemini list artifacts, create a checkout, submit a Circle developer-controlled wallet transfer, verify the resulting Arc hash, and unlock the artifact. The product stays safely on Arc testnet for the hackathon: no mainnet, no live trading, no promises of profit.

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.
