Arc enables Bitcoin liquidity with cirBTC in stablecoin ecosystem

Arc: Arc is Circle’s EVM-compatible Layer 1 blockchain positioned as an economic operating system for internet-native financial markets with a focus on stablecoin integration and institutional use cases. It recently launched mainnet and now supports native Bitcoin liquidity through cirBTC to enable productive BTC collateral across lending, trading, collateral, settlement, and treasury workflows. USDC serves as the paired borrow and settlement asset in this stablecoin-native environment. USDC: USDC is Circle’s widely adopted fiat-backed stablecoin designed for fast, reliable value transfer and settlement in digital markets. It functions as the primary borrow and settlement asset paired with cirBTC collateral within Arc’s ecosystem to support onchain credit and trading activity. Bitcoin: Bitcoin is the original decentralized cryptocurrency that functions as a global store of value and is increasingly tokenized for onchain financial applications. In this development, it is being made productive as 1:1 backed collateral via cirBTC on Arc without requiring holders to sell their underlying holdings. Launch: Arc mainnet recently launched with integrated support for cirBTC and lending infrastructure such as Morpho and Aave. Product: cirBTC provides institutional-grade 1:1 BTC-backed collateral that integrates with Circle’s custody, Mint, and stablecoin tools for seamless onchain use. Ecosystem: The combination of BTC collateral with USDC settlement strengthens onchain credit markets by allowing Bitcoin to participate directly in stablecoin-native financial workflows.
