Write a contract
Generate Solidity, review the result, and deploy to Arc Testnet. Inspect its read and write functions in the contracts panel.
Try a contract idea{ From idea to onchain }
Start small. Make it real.
Describe a project in plain language, then iterate on what Arc Studio creates.
Build the app around it
Start fresh or bring an existing contract address. Build a connected frontend and see it take shape in a live preview.
Build a prototypeFollow what happens
Explore live chain data and trace contract calls, transactions, and decoded events alongside your app’s offchain requests.
Explore the Arc docs{ Built in the community }
The conversation is already happening.
Builders are sharing what works, asking questions, and showing what they made with Arc Studio.

A Few Days With Arc Studio
Zk Fenrir shares an early experience of bringing an app's interface, smart contract, and onchain interactions together from a prompt, then invites other builders' feedback.
Built a USDC Raffle App from Scratch with Arc Studio
Fatih shares a USDC raffle prototype on Arc Testnet, including a live demo, contract link, security-review iterations, and a lesson about USDC token addresses.
Arc Studio Makes Building Faster But What Should We Still Review Manually
ZADDY ZUBAIR opens a discussion on what builders should review in generated apps, from contract permissions and wallet behavior to transaction logic and error handling.
Arc Studio: How are builders using it?
Benneth asks how other builders use Arc Studio for research and development, and what additions would help them move from an idea into a build.
From Idea to Revenue Router in Minutes with Arc Studio
Pugazhendi reflects on the Revenue Router tutorial, exploring how programmable USDC revenue splitting could support creator payouts, marketplace fees, treasury management, and other payment workflows.
Arc Studio: A New Builder Workflow
Jeet describes how natural-language prompts and exportable code could change the starting point for onchain builders, and asks what the community will create with Studio.

{ Make yourself at home }
A useful place to
build together.
You don’t need a finished product to join the conversation. A rough idea, a small experiment, or a good question is a start.
- 01
Show your work
Share a screenshot or demo, the prompt you started with, and what you’re trying next.
- 02
Ask a useful question
Include the expected result, what actually happened, and the steps that got you there.
- 03
Help someone move forward
Try a demo, suggest a clearer prompt, or share a lesson from your own build.
{ Before you start }
Frequently asked questions.
What does Arc Studio do?
Circle’s AI coding agent turns prompts into onchain apps with smart contracts, a web interface, tests, and a live preview.
What kinds of projects can I create?
Build USDC payments, checkout, escrow, payouts, bridges, tokens, NFTs, chain-data dashboards, and agents using x402.
Do I need Solidity experience?
No. Studio generates Solidity for EVM chains. Understanding the code helps you review and test the result.
Which test networks are supported?
Arc Testnet; Ethereum, Base, Arbitrum, OP, and Unichain Sepolia; Polygon Amoy; Avalanche Fuji; and Monad Testnet.
How are contracts deployed?
Built-in Arc Testnet deployments use a Circle-managed wallet. Use your own developer credentials or workflow for more control.
How can I test my app?
Use the running preview. Connect a wallet, get test USDC, and check contract state and transaction traces as you try it.
Does it work with my coding agent?
Yes—Claude Code, Codex, and Cursor. The setup prompt on Arc Studio installs its CLI and Circle skills.
Do I have to install software first?
Browser builds need no installation. The CLI is for using Studio from your own agent or editor.
How much can I use each day?
A complimentary allowance resets daily. At the limit, download your project and continue locally with Circle skills.
Can I take my prototype to production?
Studio’s reviews don’t replace an independent audit. Independently review, test, and validate generated code before mainnet use with your own credentials.
What should I share with the group?
A prototype, a prompt that worked well, a question you’re stuck on, or feedback from trying another builder’s project.
