Arc’s mainnet formally launched on Sept. 16 after more than 450,000 transactions were recorded on its last full pre-launch calendar day. More than 10,000 addresses were active before launch, including over 4,000 newly added addresses, while daily USDC transfers exceeded $300 million, according to defioasis. Roughly two hours after launch, Arc held $372 million in USDC, equal to about 0.05% of total USDC supply, and had approximately 176,000 addresses, according to monitoring by Ai 姨 cited by Odaily. Before launch, some users reportedly paid an 80%-100% USDC premium to transfer assets into Arc early for Meme coin trading. Ave integrated cross-chain swaps, on-chain trading, market tracking and X monitoring, while Arc activity included the $ARGUS token surpassing a $20 million market capitalization. Arc had previously said its Economic OS would let machines spend USDC under predefined rules and settle transactions on the network.
