DenaroFX is a wallet-enabled FX execution agent built with Google ADK, Gemini, Circle developer-controlled wallets, Arc App Kit, x402 payments, and Denaro Intelligence. The agent starts from a natural-language request and turns it into an executable financial workflow. Through Google ADK, we expose wallet, balance, swap estimation, x402 payment, and route scoring functions as tools. Gemini interprets the user’s request, selects the right tools, and chains them together. Circle developer-controlled wallets are used to create and manage the agent’s wallet programmatically. The agent can create a wallet, check its balance, and use that wallet as its payment and execution identity. Arc App Kit is used to estimate stablecoin FX swaps, including expected output, fees, and route data. When the user asks for execution scoring, the agent uses x402 to pay for access to the Denaro Intelligence API. Denaro then receives the swap estimate, scores execution quality, and returns a recommendation: execute directly, reject the route, or split the flow across onchain and OTC liquidity. Financial agents should not blindly execute the first quote they receive. A small swap may be acceptable, while a larger USDC to BRLA trade can expose worse liquidity, higher slippage, or better OTC alternatives. DenaroFX Agent demonstrates an agent that can estimate, pay for intelligence, evaluate execution quality, and make a route decision before acting.

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.
