Arc mainnet launches: USDC hits $372M and 176,000 active addresses in two hours

AI Market Summary
Arc's mainnet launch shows rapid USDC adoption, reaching ~372M USDC and ~176k active addresses within two hours. The early bridging premium (80%–100%) suggests acute demand for onchain liquidity and speculative activity (meme trading) around the new venue. Near term, this can tighten cross-chain USDC availability and concentrate liquidity on Arc, influencing stablecoin flows and risk appetite across adjacent ecosystems.

BlockBeats reported on Sept. 16 that, according to Ai Yi monitoring, roughly two hours after Arc's mainnet went live, the Circle-backed public blockchain held about 372 million USDC. That figure represents around 0.05% of total USDC in circulation. The network was also seeing approximately 176,000 active onchain addresses at the time. Ahead of the launch, some users had already bridged funds to Arc, paying an 80%–100% premium in USDC to join early meme-coin trading.
