Circle launches Arc Studio AI agent to help build on-chain applications

Circle 推出 Arc Studio：基于自然语言提示生成全栈链上应用的 AI 编码代理

Arc Studio 是一款由 Circle 推出的 AI 编码代理，能够根据自然语言提示生成全栈链上应用、智能合约以及自动化代理。该工具旨在简化区块链开发流程，使开发者能够通过描述性语言快速构建应用程序。

核心功能与特性

Arc Studio 能够从自然语言提示中自动生成前端界面、后端逻辑和智能合约。其主要特点包括：

• 多链测试支持：开发者可以在九个不同的区块链网络上对生成的应用进行测试，并将代码导出至自己的代码仓库。
• 广泛的协议集成：Studio 支持 USDC 支付、钱包管理、代币兑换、跨链桥接，并与 Aave、Morpho 和 Uniswap 等主流协议实现集成。
• 无缝接入现有工作流：用户可以通过 Web 界面访问 Studio，或将其作为子代理集成到 Claude Code、Codex 和 Cursor 等现有编码工具中。

此次发布紧随 Arc 公共主网的正式推出，标志着 Circle 在扩展其开发者工具和 AI 代理基础设施方面迈出了重要一步。根据 9 月 17 日的公告，Arc Studio 允许用户通过文字描述想要构建的应用，系统随后将组件组装成可运行的原型。生成的应用程序可在 Arbitrum、Arc、Avalanche、Base、Ethereum、Monad、OP Mainnet、Polygon 和 Unichain 等九个区块链网络中进行测试。

简化开发流程

Arc Studio 的设计初衷是处理那些通常需要开发者单独配置钱包、Gas 费用、合约、协议集成和测试网基础设施的复杂环节。用户只需使用通俗语言描述应用需求，Studio 即可自动组装各组件形成工作原型。开发者随后可将生成的代码导出到自己的仓库中，审查底层逻辑，并使用自己的凭证和基础设施进行生产环境部署。

该平台支持 Solidity 合约的编写、初步审查以及部署至 Arc Testnet 或其他八个 EVM（以太坊虚拟机）测试网。其界面提供了合约读写功能的访问权限，同时具备追踪系统，可记录 RPC 调用、交易、解码事件以及应用生成的链下 HTTP 请求。

Circle 警告称，AI 生成的代码可能存在错误、安全弱点或输出不完整的情况，因此必须经过独立审查和测试。Studio 不会代表用户签署、资助或提交主网交易，生产环境的部署仍由开发者使用自身的凭证和基础设施完成。

以 USDC 支付为核心

Circle 将 Studio 定位为围绕 USDC 资金流的应用平台，涵盖支付、兑换、钱包、桥接、借贷、质押及可编程支付等功能。例如，开发者可以通过提示词构建具有管理界面和钱包功能的跨境支付应用，或为数字商品提供稳定币支付解决方案，甚至建立允许 AI 代理之间相互支付或购买计算资源的基础设施。

通过整合 Aave、Morpho 和 Uniswap 的可组合服务，Studio 使得生成的应用能够直接利用现有的 DeFi 基础设施，无需开发者手动连接每一个集成模块。

与此同时，Circle 正在不断扩展处理此类交易的基础设施。今年 9 月发布的 CCTP（跨链传输协议）更新增加了“快速转账”的前置费用支付功能，允许应用在源网络上报价并收取跨链 USDC 费用，同时保持接收方收到的金额不变。CCTP 采用燃烧和铸造机制在支持的链间转移原生 USDC，而较新的 Quote API 可将符合条件的协议费用合并为签名且有时效性的报价，预付费用可使用 USDC 或源网络的 Gas 资产结算。

The rise of autonomous software payments

The release of Arc Studio comes as Circle explores payment use cases initiated by autonomous software. In August, Circle released data showing that 99.3% of the payment transaction volume measured through the x402 agent payment protocol in the second quarter was settled in USDC. Although this data only covers protocol activity measured by Circle and does not represent the share paid by all AI agents, it is sufficient to prove USDC's dominance in the machine economy. In addition, Circle's Agent Stack launched in May already included more than 900 paid services at the end of the second quarter.

Comprehensive expansion of Arc Ecosystem

The release of Arc Studio is accompanied by a larger expansion of the Arc Ecosystem after its launch on the public main network on September 16. Previous reports pointed out that the launch of Arc's main network marks the official launch of Circle's Layer 1 network, which uses USDC as the transaction fee currency, achieves deterministic settlement in less than one second, and supports Ethereum virtual machine applications.

Arc launched with Circle and 11 founding verifiers from well-known institutions, including BlackRock, DTCC, Galaxy, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered Bank, Sumitomo Corporation, Visa and Worldpay, a subsidiary of Global Payments. According to Circle, more than 100 applications and more than 100 institutions and ecosystem builders were running on the network when the main network was launched. Arc initially integrated partners in multiple fields such as banks, asset management companies, payment companies, exchanges, custodians, wallets, DeFi protocols and AI platforms.

The network supports 22 types of fiat currencies and launched tokenized funds such as BUIDL, USYC, JAAA and JTRSY at its launch. With CCTP and Circle Gateway, Arc provides a path to move supporting assets and gain liquidity between more than 20 blockchain networks.

Arc is built in an EVM-compatible environment and allows developers to use Solidity and existing Ethereum development tools. USDC, as a native asset to Gas Metrics, eliminates the need to hold separate network tokens to pay for ordinary transaction fees. Before the mainnet was launched, Arc operated as a private mainnet with more than 100 institutions and ecological participants; its early public test net had processed more than 700 million transactions before the mainnet was opened.

Continuing to deepen developer and agent tools

Arc Studio is just one of a series of products Circle has built around Arc to serve developers, institutions and autonomous agents. Other supporting products include:

• Arc App Kits: provides packaged common financial function components such as payment, exchange, fiat deposit and income aggregation.
• Arc Portal: Provides users with an interface for injecting funds into agent wallets, setting expenditure limits, and delegating specific on-chain tasks.
• Circle Agent Stack: provides policy-controlled wallet and micro-payment capabilities;Agent Wallets are designed specifically for software that allows it to hold, trade and bridge USDC within human-set spending rules.

In terms of institutional capabilities, Circle earlier this year disclosed plans for confidential smart contract capabilities, in which Arc Privacy is designed to protect the privacy of selected financial information while retaining access needed for audits and compliance reviews. Circle believes confidential contracts have potential uses in areas such as payroll, treasury management, tokenized assets, trading and lending.

Studio is currently accessible through its Web interface and can be used as a sub-agent by developers working in existing coding environments. The resulting application remains exportable, allowing the team to review the code and move it to its own warehouse and use its own keys and infrastructure for final deployment.
