USDC Mainnet, Circle Launches Arc Network!

🚀 The Rise of an Ultra-Fast Blockchain

On August 12, 2025, Circle, the global leader in the stablecoin market, officially announced the launch of its new Layer-1 blockchain — Arc Network Mainnet.
Arc Network stands out with up to 33 times faster throughput than Ethereum and a USDC-native gas token model, aiming to solve the speed, cost, and compliance limitations of existing blockchain infrastructure.

This launch is not just a product update — it signals Circle’s ambition to reshape the global payments and finance industry with a stablecoin-first blockchain.

 

💡 Why Circle Built Arc Network

With USDC, Circle has already processed over $28 trillion in on-chain transactions, maintaining its position as the top player in the stablecoin market.
However, current blockchain environments present critical bottlenecks for large-scale financial applications:

  • High transaction fees leading to unpredictable costs
  • Slow transaction speeds, making real-time payments and remittances difficult
  • Lack of regulatory-friendly features, limiting adoption by financial institutions

Arc Network was designed to address these issues head-on.
By using USDC as the native gas token, Arc eliminates fee volatility, provides ultra-fast settlement, and offers compliance features tailored to bridge traditional finance and Web3.

⚙ Key Features & Technology

Arc Network is an EVM-compatible, open-source blockchain, allowing developers to use existing Ethereum smart contracts and tools without modification.

It uses the Malachite consensus (based on Tendermint BFT), delivering:

  • Up to 10,000 TPS (transactions per second)
  • 100–350ms finality

This makes Arc Network up to 33x faster than Ethereum.
All transaction fees are paid in USDC, ensuring predictable costs for both enterprises and retail users.

To prevent MEV (Miner Extractable Value) exploits, Arc features an encrypted mempoolbatch transaction processing, and a multi-proposer architecture.

🛡 Compliance & Security for Financial Institutions

Arc leverages Trusted Execution Environment (TEE) technology to securely protect transaction data.
The View Keys feature allows regulators and auditors read-only access to transaction details when required, striking a balance between blockchain transparency and compliance with financial regulations.

This dual approach makes Arc highly attractive to banks, fintech companies, and payment processors looking for a secure and regulation-ready blockchain infrastructure.

🌐 Cross-Chain Interoperability

Arc Network comes with Circle’s Cross-Chain Transfer Protocol (CCTP) built-in, enabling seamless USDC transfers across major chains such as Ethereum, Solana, and Base.

Instead of existing as a siloed chain, Arc positions itself as a hub for the global stablecoin ecosystem.
Its open-source nature also encourages developers to build diverse Web3 applications — from DeFi protocols and NFTs to payment solutions.

📈 Potential Impact of Arc Network

The Arc Network Mainnet launch could trigger major changes in the blockchain and payments landscape:

  1. Borderless Real-Time Payments – Faster and cheaper than traditional banking systems
  2. Accelerated Institutional Adoption – Compliance-ready design increases trust among financial entities
  3. Expanded Stablecoin Ecosystem – USDC as the core medium of exchange for digital assets and services

Final Thoughts

The launch of Arc Network Mainnet marks Circle’s move to redefine the global financial infrastructure through a stablecoin-first approach.
With 33x faster speeds than EthereumUSDC-native fees, and regulatory-friendly architecture, Arc is positioned to be a game-changer bridging traditional finance and digital assets.

Starting with its public testnet in Fall 2025, all eyes will be on Arc Network to see how it will transform payments, settlements, and Web3-powered finance.
