TREE NEWS update: Circle has launched the Arc mainnet, a Layer 1 that charges gas in USDC and runs proof-of-authority across a permissioned set of 11 institutions plus Circle, including BlackRock, DTCC and Visa as block producers. More than 100 applications are live at launch, with Aave, Morpho and Uniswap anchoring DeFi. Circle minted 10 billion ARC tokens this week without committing to a public launch.
Circle Launches Arc Mainnet With BlackRock, DTCC and Visa Producing Blocks
Arc's design choice matters more than its launch: gas denominated in USDC and a permissioned validator set of named financial institutions signal a compliance-first settlement layer rather than an open, permissionless chain. That places Circle in direct competition with bank-adjacent tokenization efforts while anchoring DeFi protocols on institutional rails. The unresolved question is the 10 billion ARC minted without a committed public launch — whether that supply ever reaches open markets will shape how decentralized Arc is perceived to be.
