Circle's newly launched Arc blockchain was built to handle payments, tokenized assets, and institutional financial activity, with the backing of some of the world's largest financial institutions. However, on its first day, the most visible users of the network were speculative memecoin traders.

Arc went live on September 16, 2026, with a founding validator group — the entities responsible for verifying transactions and maintaining the network — that includes BlackRock, Visa, Mastercard, the Depository Trust & Clearing Corporation, ICE, MoneyGram, and Standard Chartered, along with other large financial firms. Circle initially presented Arc as a Layer-1 blockchain purpose-built for stablecoin finance, and the network uses the company's USDC — one of the world's largest dollar-backed stablecoins — as its native gas asset, meaning users pay transaction fees in the stablecoin itself rather than in a separate network token. Circle has described Arc as its most significant launch since USDC, positioning the network as infrastructure for institutional finance and an emerging machine-driven economy in which automated systems and AI agents transact on-chain. BitcoinKE previously reported that Circle raised more than $200 million in the Arc blockchain token pre-sale.

Despite that institutional framing, speculative traders quickly became the most prominent presence on the new chain. According to Arc's Blockscout block explorer, the network processed around 7.83 million transactions in its first 24 hours, while lifetime USDC transfers stood at roughly 624,000 — a gap suggesting that most of the early activity had little to do with the payment use cases that Arc was designed to support. The network also attracted about 400,000 new accounts and more than 73,000 deployed contracts.

Decentralized exchange (DEX) activity reached roughly $82 million on day one, with newly launched memecoins — tokens typically inspired by internet jokes and trends — accounting for much of the speculative volume. Several of the most actively traded tokens subsequently fell sharply from their launch highs, including TOLLY, LONG, and COOL.

The pattern echoes the experience of Robinhood Chain, another blockchain promoted around institutional financial applications that nonetheless saw memecoin trading dominate its early activity. Robinhood Chain recorded around $878 million in DEX volume during its own memecoin-driven surge in July 2026. The broader frenzy has also produced security incidents: BitcoinKE separately reported that Robinhood's CEO had his X account hacked to promote a fake token.

Circle's challenge, therefore, is less about whether Arc can process transactions — the network has been operating with sub-second finality, meaning confirmed transactions become irreversible in less than a second, and without congestion — and more about what type of economic activity it ultimately attracts. That distinction matters for an institutional project because mere processing capacity does not demonstrate the payment and settlement functions a network like Arc was built to serve.

The network launched with more than 100 applications from institutional builders and the ecosystem. Aave, Morpho, and Uniswap are among the available protocols, while BlackRock's BUIDL and Circle's USYC are among the tokenized funds being brought onto the chain — a launch lineup that combines established decentralized finance venues with the tokenized funds at the core of Arc's institutional proposition. BitcoinKE has also reported that Circle overtook BlackRock to become the largest issuer of tokenized assets. Additionally, Circle is developing infrastructure for confidential institutional transactions and AI agents on the network.

The launch-day fervor also reached Circle's own team. Arc's product chief drew criticism after posting an AI-generated image promoting a memecoin associated with the dog of Circle's CEO, Jeremy Allaire. The post attracted roughly 1 million views and prompted accusations from some traders that the company encouraging speculative activity around its new network.

The early figures highlight a familiar tension for institutional blockchain projects: building infrastructure for banks and asset managers does not necessarily determine who arrives first. Arc was designed around stablecoins, tokenized assets, payments, and institutional settlement. Instead, its first major wave of users arrived looking for the next speculative token trade. How the balance of activity shifts toward broader use of payments, tokenized funds, and AI agent tools is likely to be the clearest indicator of whether Arc's institutional framing extends beyond launch week.
