Arc hits nine figures in TVL on day one!

Circle's Arc blockchain went live on Wednesday, September 16, 2026, putting block production in the hands of some of the biggest names in traditional finance. The launch generated immediate buzz, and the on-chain numbers backed up the hype: Total Value Locked across the network crossed $300 million on day one, according to DeFiLlama data, representing an increase of over 654,000%. The chain is already on track to reach half a billion dollars in TVL.

Institutional Validators and a Wave of Integrations

The planned full list of validators includes BlackRock, DTCC, Galaxy, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered, Sumitomo Corporation, Visa, and Worldpay (now Global Payments). That validator roster signals an unusually institutional starting point for a blockchain network, setting Arc apart from most Layer 1 launches that rely on crypto-native infrastructure providers alone.

Circle opened the public mainnet with a new Aave V4 lending market, Morpho, and Uniswap among the protocols available from day one, with more than 100 applications live at launch overall. Bitget Wallet was also part of the day-one launch, giving its 100 million users immediate access to the network.

Built for Finance, Fees Paid in USDC

Arc is designed to feel like conventional payments infrastructure. Gas is paid in USDC rather than a volatile token, settlement is sub-second, and opt-in privacy is planned. The blockchain arrives as Circle tries to diversify beyond issuing its $74 billion $USDC stablecoin. Circle CEO Jeremy Allaire has publicly described Arc as "a bigger opportunity than USDC."

Arc's public testnet launched in October 2025 and processed more than 700 million transactions in less than a year. The day-one TVL milestone suggests demand is real, not just a product of validator name-dropping, though the next 12 months could determine whether Arc drives measurable ecosystem adoption or becomes another blockchain ecosystem measured by partnerships more than usage.
