The Arc eco is Circle new financial layer for the internet. Its mainnet went live on Sept 16, 2026 and already shows real activity: tens of millions of transactions, millions of addresses, fees paid in USDC, and settlement in under one second. Big institutions like BlackRock, Visa, Mastercard, and DTCC help run the network. That mix makes Arc a serious place for payments, on-chain FX, tokenized RWA, and AI agent activity, not just another blockchain.
Projects on Arc Eco are moving fast. Launchpads such as
$ARGUS and
$TOLLY, prediction markets, plus DeFi, trading, and payment apps sit on a growing list of 232+ projects. Cheap, predictable USDC fees and familiar Ethereum tools make it easy to launch tokens and apps. Partners like Eco also connect Arc to other chains. Rising USDC supply and early institutional tokenized assets show that real money and real use cases are already arriving.
Looking ahead, Arc plans a move toward Proof of Stake. The ARC token, already minted at genesis, is meant to help secure the network, support governance, and reward longterm participants, while fees stay in USDC. With Circle behind it, strong testnet history, and a clear focus on finance that creates ongoing volume, tokens and projects in Arc Eco are well placed to grow with stablecoin payments, RWA, and the agent economy. This is live infrastructure attracting builders and capital right now.
