Circle's USDC stablecoin has recorded daily trading volume of approximately $2.8 billion across decentralized exchanges (DEXs), its highest level in 30 days. The milestone was highlighted by crypto commentator @tokenterminal on X, pointing to growing engagement with the stablecoin as traders increasingly lean on stablecoin pairs for decentralized trading. USDC is designed to maintain a 1:1 peg to the US dollar and ranks as the second-largest stablecoin by market capitalization, behind Tether's USDT. Dollar-pegged assets of this kind are widely used on DEXs as a base pair for moving between volatile crypto assets without converting to fiat.

Volume Figures

The latest figures show that total USDC trading volume over the past 30 days reached $29.1 billion, a 166.7% increase compared with the previous month. Uniswap V3 and Uniswap V4 played a critical role in this activity, together accounting for $16 billion, or 55% of the total volume. Uniswap, which operates across multiple blockchains, is the largest decentralized exchange protocol by trading volume.

The uptick in DEX volume comes amid a broader crypto market exhibiting mixed signals, with various assets showing fluctuating momentum. Against that backdrop, the data indicates rising use of USDC for liquidity and trading efficiency as decentralized finance (DeFi) continues to evolve.

Market Snapshot

Market data at the time of reporting listed USDC as trading at $0, with 24-hour volume figures not available. Even so, the recent trading activity indicates heightened use of USDC as a stable trading pair. The strong performance on DEX platforms underlines the stablecoin's role in maintaining market stability and facilitating transactions during volatile periods.

Circle, the issuer of USDC, is a technology company focused on enabling secure and efficient cryptocurrency transactions, and it went public on the New York Stock Exchange in June 2025 under the ticker CRCL. USDC reserves are held primarily in cash and short-duration US Treasury instruments, with monthly attestation reports published on their composition. In the United States, the GENIUS Act, signed into law in July 2025, established a federal regulatory framework for payment stablecoins that sets requirements covering reserve backing and disclosure. The regulatory environment surrounding stablecoins and decentralized finance has drawn increased scrutiny, a context that makes the growth in USDC trading particularly significant for the broader crypto ecosystem.

What Comes Next

Developments to monitor include further movement in USDC's DEX trading volume, where continued growth has been associated with stronger adoption in the crypto market, and the performance of Uniswap V3 and V4, which remain central to USDC's liquidity. Fluctuations in overall market conditions may also shape trading strategies and interest in stablecoins going forward. Circle's monthly reserve attestations provide a recurring disclosure point on the stablecoin's backing, and the implementation of the new US federal stablecoin rules is another item to watch.
