According to CoinMeta, Circle launched its mainnet, ARC, on Wednesday, with global financial giants such as Blackstone, DTCC, Visa, and Mastercard participating in ensuring network security. ARC provided unprecedented financial infrastructure for Circle, supporting transactions after its issuance. USDC has already been circulating on multiple external blockchains, and ARC has also added its own Layer 1 to support the payment of transaction fees with USDC, handle currency exchanges, settle tokenized financial instruments, and provide credit through lending agreements. Circle reported a total revenue of $701 million in its Q2 report, of which $668 million came from reserve income, indicating its dependence on USDC assets. Although the circulation volume of USDC increased by 25% year-on-year, reserve income only grew by 5%. The launch of ARC is aimed at strengthening the infrastructure for Circle and promoting further adoption of USDC.
