Circle's Arc mainnet went live on September 16, 2026, with gas and settlement denominated in USDC, and BlackRock, Visa, Mastercard and DTCC are among the network's founding validators. A fuller validator list reported at launch also includes ICE, Standard Chartered, Galaxy, SBI, MoneyGram, Sumitomo and Worldpay/Global Payments alongside Circle, with the network designed to carry FX infrastructure directly onchain. Uniswap said Uniswap v2, v3, v4 and UniswapX have integrated Arc Layer 1, making Uniswap the preferred DEX on Arc from mainnet day one. Figment is offering managed validator services on Arc at mainnet launch, enabling institutional validator participation, and Wirex launched its Wirex One stablecoin neobank globally as a day-one partner on Arc, with $2B in annualized card spend. Chainlink is providing institutional-grade oracle infrastructure via Data Feeds, Proof of Reserve, Data Streams and CCIP, and RedStone is live on Arc mainnet from day one with NAV feeds for tokenized RWA. Centrifuge is building the fixed-income market on Arc from day one, bringing tokenized Treasuries ($JTRSY), AAA CLOs ($JAAA) and high-yield bonds ($HYB) at launch alongside JHI Advisors and NYLIM. Maple Finance's Maple token is live on Arc from day one, targeting fintechs, neobanks and payment companies that hold customer dollars and want them to earn yield. KuCoin is a mainnet launch partner, letting eligible users move USDC directly between KuCoin and Arc from day one. Aster has integrated Arc for USDC deposits and withdrawals, extending stablecoin-margined perpetual trading on the exchange. Arc has been integrated into the multichain launchpad PumpFun, and more than 190 institutions and ecosystem participants are building on the network. edgeX launched on Arc mainnet with 24/7 FX perpetuals and more than 150 perpetual markets across stocks, commodities and crypto, settling natively in USDC. Turkish exchange Paribu opened USDC deposits and withdrawals over Arc from day one, and Morpho is live on Arc as its credit infrastructure. Bitget Wallet opened an Arc bridge using Circle's CCTP, supporting transfers from Ethereum, Polygon, Arbitrum, Solana, Base, Morph, HyperEVM and BSC. RocketX made Arc mainnet live on its swap interface, offering swaps across Arc and 200+ networks through combined CEX and DEX liquidity, and Yellow connected Arc to its clearing layer so agents and applications can trade and settle from day one without handing funds to a custodian. Contrary to the whitepaper's earlier plan to leave ARC unreleased, 10 billion ARC tokens have been minted, with no public launch of the tokens yet decided. First-day activity was heavy: about 9.1M transactions at an average fee of 0.02 USDC and $79.8M in DEX trading volume, with $ARGUS ($24.3M) and $TOLLY ($10.2M) the most traded launchpad tokens. Circle CEO Jeremy Allaire called Arc "more consequential" than USDC. The launch follows 10 months of testnet, which since October 2025 ran 3.43M real wallets, 48.3M contracts deployed, 10.9M tokens created and 42.2M stablecoin transfers. Robinhood has said it will support Arc L1, and USDC on Arc has reached about 371.7M tokens, roughly 0.05% of total USDC supply, across some 176,000 addresses.
