USDC supply on Arc tops $1B after 109.4% jump in 30 days

Circle's new blockchain crossed the milestone about six weeks after its mainnet launch, even as global stablecoin supply contracted Circle’s Arc blockchain now holds more than $1 billion in USDC . That supply grew 109.4% over the past 30 days. Put plainly, the amount of USDC sitting on Arc more than doubled in a month. For a network that opened its public mainnet in mid-September, the pace is fast. The timing makes it more interesting. Arc kept growing while the global stablecoin market was shrinking. USDC supply on Arc first passed $1 billion on October 27, 2026.
