Circle has unveiled Arc Studio, an artificial intelligence (AI) coding agent dedicated to its blockchain-based Arc network.

On Sept. 19 local time, blockchain outlet CoinPost reported the tool is designed to let users build onchain applications, smart contracts and AI agents by entering a prompt.

Arc Studio generates a full-stack application within minutes when a user describes the desired service in natural language. It produces the frontend UI and backend logic, including smart contracts. Circle said it boosts development speed overall and lets less experienced developers start building more easily.

The approach focuses on lowering the barriers to entry in existing onchain development. It can be used directly in a web browser. It can also be connected as a sub-agent in development tools such as Claude Code, Codex and Cursor, allowing users to keep their existing workflow. Circle said existing onchain developers had to complete preliminary steps such as wallet setup and gas management, and that this could lengthen development time even for experienced developers.

The unveiling comes shortly after the launch of the Arc mainnet. The layer 1 network underpinning Arc uses the USDC stablecoin for gas fees, and 11 large financial institutions and companies, including BlackRock, the Depository Trust & Clearing Corporation (DTCC) and Visa, are participating as validators.

Arc Studio also reflects Circle's developer stack. Circle said it is designed to understand CCTP, contracts, gateways, wallets and other stablecoin infrastructure, allowing apps to be built on consistent components rather than at a general abstraction level. As a result, services generated can integrate various protocols and assets in a form that can be run in practice.

It also broadened support. Developers can test outputs across nine blockchains: Arc, Arbitrum, Avalanche, Base, Ethereum, Monad, OP Mainnet, Polygon and Unichain. This is read as a setup that, while Arc-centric, also targets a multi-chain environment.

Use cases were presented in finance, consumer services, software-as-a-service and AI platforms. In finance, developers can build apps such as payments, swaps, wallets, bridges, lending, staking and programmable payments using USDC. In consumer apps, they can test in-app stablecoin payment experiences tailored to digital goods sales or creator monetisation.

Scalability for enterprise services was also presented. A software-as-a-service platform can build usage-based billing flows where USDC payments are executed depending on consumption. An AI platform can experiment with payment flows between agents or based on computing resource usage. Circle is positioning Arc Studio not just as a development convenience tool but as a means to expand services that use USDC.

In this context, Arc Studio is also drawing attention as a tool to accelerate ecosystem expansion shortly after the Arc mainnet launch. It effectively aims to bring in developers and drive real service experimentation at the same time by opening network infrastructure first and then immediately adding developer tools. In particular, as Arc has adopted a structure that uses USDC for gas fees, attention is expected to focus on how quickly Arc Studio brings in payment and finance-type apps.

Introducing Arc Studio. Arc Studio is an AI-powered workspace for building onchain applications on Arc, from idea to smart contract logic to deployment. It helps developers move faster without turning the build process into a black box. → Generate smart contracts → Review… pic.twitter.com/IqiDv5EyjU
