Circle’s native layer-one blockchain Arc recorded $410.8 million in decentralized exchange (DEX) volume and 7.76 million transactions on the first day of its mainnet launch, Cryptopolitan reported, citing Dune Analytics data. About $336.3 million, or roughly 82% of total DEX volume, came from a memecoin launchpad. The figures indicate that activity on Arc’s opening day was heavily concentrated in memecoin trading and issuance through that platform.
