Circle’s Arc Tops $1 Billion in USDC

Circle's Arc network has surpassed $1 billion in USDC, with the stablecoin's market cap on the chain rising 32% in a week according to DefiLlama data. However, concentration is high: four addresses hold roughly 73% of the network's USDC. Traders would see the growth as a positive signal for Circle's ecosystem, but the heavy whale concentration raises liquidity and centralization risks worth monitoring.
