Arc Network is now live with its public mainnet.
Circle’s own Layer 1 blockchain Arc is officially live with a nearly 200 network of global partners and participants across traditional finance and ecosystems.
The stablecoin giant is tackling the diverse landscape of transfers and settlement, including: swaps, funding, borrowing and lending, developer solutions, and more for tokenizing real-world assets.
Originally, Arc launched a public testnet in Fall 2025 to seek feedback from early users and integrators. In April 2026, it open-sourced the code and Arc testnet transactions reached 311M.
Similar to the Canton Network, it will have a dedicated validator set comprised of mainly top institutions, such as MasterCard, Standard Chartered, BlackRock, and others.
The launch date was revealed in early August during its Circle Q2 2026 earnings results.
Do We Really Need Another Blockchain?
There are already so many blockchain networks out there.
The crypto industry and companies building onchain realized in the last few years that building a network just for the sake of it is probably not the best way to outcompete existing chains.
Top blockchains such as Ethereum and Solana are years ahead in public testing with strong distributions, and are the usual choice for entities, users, and developers. So why launch another one?
Circle frames this as a solution that solves multiple problems.
How Arc Network Helps Circle Grow
Firstly, it pins the company’s biggest asset – USDC stablecoin – at the core of Arc Network’s offering. Specifically, all transfers will have USDC as the native gas token for moving funds from one place to another.
Circle’s USDC is second largest stablecoin in supply and issuance. Frequently, it has accounted highly as leading stablecoin volume and DeFi stablecoin lending in 2026.
Therefore, Arc Network serves as additional distribution channel outside of Circle’s third-party agreements.
Secondly, it allows for a more advanced usage of a network intended for moving value onchain.
This means that several use-cases are available to interested parties all at once: FX, Agentic AI integration, payment routing, and many other infrastructures for adopters of this technology.
Thirdly, Circle adds to its already competitive stance in the stablecoin market. Issuance, global licensing, being the only stablecoin public company, and now running a dedicated Layer 1.
Outside of this, it recently signed the USDC Chelsea sponsor deal for the UK Premier League and acquired TazaPay.
It remains to be seen the level of adoption Arc Network will have among users and institutions.
