Circle, the company behind the stablecoin USDC, has unveiled the public testnet for its Arc blockchain. The move comes a couple of months after the USDC issuer introduced Arc, a layer-1 blockchain network for real-world economic activity onchain. Arc’s debut was in August 2025, and two months later, on October 28, 2025, the L1 is going live in public testnet. Circle opens Arc blockchain public testing Publicly-traded Circle said in August 2025 that Arc would be an open L1 blockchain designed as the foundational ‘Economic OS for the internet’. Its target is to help scale networks for stablecoins, tokenized assets, and global financial applications. “Far more than just a blockchain for USDC, Arc is designed to be the home for all forms of digital money and tokenized value,” Nikhil Chandhok, chief product & technology officer at Circle said at the time. Arc is now open for public testing as Circle looks to bring this vision to reality. The public testnet, now accessible to all developers and companies, allows for the deployment of smart contracts, testing of transaction flows, token launches, cross-chain transfers, and wallet operations. Arc uses USDC as the native gas token. It also offers full-stack integration of Circle’s suite of tools, including native support for Circle Payments Network, stablecoins USDC and EURC, cross-chain interoperability via protocols CCTP and Gateway, and developer tools like wallets. What happens? Developers can put Arc to the test via smart contracts deployment and testing of transaction flows, as well as launching tokens with a key focus on testing swaps and cross-asset interactions. The public testnet also allows developers across the ecosystem to conduct cross-chain transfers and validate wallet operations. Circle says it will initially steward the network’s development and operations. However, it plans to have a decentralized governance system as Arc becomes a neutral infrastructure layer. The mainnet launch is anticipated in 2026, and the testnet provides for rigorous testing to ensure performance, security, and integration robustness. Visa, HSBC and BlackRock among major firms to join the Arc testnet Ecosystem players already helping to put Arc through the paces include global giants across stablecoin issuers, digital payments, banks , asset managers, and capital markets. This robust ecosystem of global financial leaders rallying around the Arc testnet includes the likes of Visa, HSBC, and BlackRock. Visa contributes to the payments and fintech segment, enhancing cross-border transaction capabilities. Meanwhile, HSBC, as a major bank and asset manager, brings expertise in traditional finance integration, and BlackRock, a leading asset manager and insurer, focuses on tokenized funds and investment strategies. Other notable collaborators include digital wallets such as MetaMask and Ledger, developer tools platforms Alchemy and Chainlink, and decentralized exchanges such as Uniswap. Banks include Deutsche Bank and Goldman Sachs, while NYSE and State Street are among capital markets players. The post Circle launches public testnet of Arc blockchain appeared first on Invezz
