Build Your First Onchain App: Prompts + Building with Arc Studio
Build and ship your first onchain app in one evening - just by describing what you want.
Join us at Encode Hub for a hands-on builders night with the Arc team. You'll see Arc Studio in action, then build your own app with it, with Circle's team on hand to help.
What is Arc Studio?
Arc Studio is Circle's new AI coding agent for building onchain apps. Describe what you want in plain English and it writes, previews and deploys a working app on Arc - smart contracts, frontend and payment flows included. It also works alongside tools you already use, like Claude Code, Codex and Cursor.
What is Arc?
Arc is Circle's open Layer-1 blockchain, built for stablecoin finance. It went live on mainnet in September with USDC as its native gas, so fees are predictable and dollar-denominated, and transactions settle in under a second.
What could you build?
A payment app that takes USDC
An AI agent with its own wallet that can pay for things
A tipping jar, paywall or simple marketplace
A savings or treasury tool
Anything else you've wanted to try onchain
