Memecoins Take Over Arc Blockchain on Day One

How Circle’s institutional Arc blockchain got taken over by memecoins on day one

Circle’s new Layer 1 blockchain, Arc, launched with an institutional payments pitch. But in its first 24 hours on mainnet, network activity was overwhelmingly driven by memecoins rather than stablecoin payments, according to on-chain data from Arc’s Blockscout explorer and early trading figures.

Arc processed 7.83 million transactions in its first day, alongside roughly 400,000 new accounts and more than 73,000 deployed contracts. Even with that burst of activity, lifetime USDC transfer count was about 624,000, suggesting that most transactions were not simple payment flows.

As blocks filled with memecoin activity, network costs moved higher. Average fees quadrupled to about $0.03, despite Arc’s design goal of predictable fees for financial users.

Traders on social media quickly framed the launch as a short-lived memecoin cycle. “Arc is one day old, and every coin is already down like 50–80%,” trader wale.moca wrote on X, later adding: “It’s cooked.” Another user referred to it as a “one-day arc.”

Price moves cited for several Arc-based memecoins reflected that negative tone, with TOLLY down 56%, LONG down 77%, and COOL down 75% from launch highs.

Early decentralized exchange activity was also modest compared with other recent launches that saw memecoins dominate. Day-one DEX volume on Arc ended around $82 million, versus $878 million recorded on July 12 for Robinhood Chain, whose own institutional narrative was similarly overtaken by memecoins. Arc’s largest token by market value, ARGUS, was worth about $16 million, while the second- and third-largest were cirBTC and EURC, both tied to Circle’s products.

Arc was built to appeal to institutions that want stable, fast settlement rails rather than the volatility and fee swings common on general-purpose blockchains. Circle has positioned the network for stablecoin-based transactions, cross-border settlement, and tokenized real-world assets, emphasizing that Arc offers sub-second finality and gas fees paid in USDC rather than a volatile native token.

In a press release announcing the public mainnet launch, Circle described Arc as a Layer 1 for “financial markets and real-time money movement,” launching with native integration of USDC, which Circle said has more than $74 billion in circulation. Circle CEO Jeremy Allaire called Arc “the single most significant launch in Circle’s history since USDC itself.”

Circle said it completed a genesis mint of an ARC token in the U.S., creating an initial supply of 10 billion. The company stated the mint was not a commitment to publicly launch ARC, and framed it as a technical milestone as the network explores a possible shift from Proof of Authority to Proof of Stake in 2027.

At launch, Arc included trading and application infrastructure such as Aero, fomo, and Uniswap, and supported assets including Circle’s USYC money market fund and the BUIDL treasury fund. Circle has also said Arc is being developed with configurable privacy features intended for institutions that need to limit transaction visibility while preserving access for auditors and regulators.

The day-one memecoin surge matters because it highlights a recurring pattern in crypto: new blockspace, even when marketed for enterprise use, can be quickly consumed by speculative activity. In Arc’s case, the spike in contracts, accounts, and fees came immediately, while the payment flows Arc was built to prioritize appeared to represent a smaller share of early usage.

Circle has said Arc is launching amid intensifying competition in stablecoins and blockchain-based settlement. The company also said more than 100 institutions and ecosystem companies were participating in or exploring the network, naming firms including BlackRock, Mastercard, Visa, BNY, and HSBC.
