The stablecoin market has been booming, with on-chain transaction volumes hitting a record high of $1.5 trillion in July. This surge marks a significant milestone for the sector, showing strong growth and adoption.
Data from Sentora (formerly IntoTheBlock) reveals that this figure is a substantial increase from the $1.26 trillion processed in June. It also surpasses the previous high seen in August 2024, when volumes topped $1.4 trillion. The chart below illustrates the steady growth of stablecoin on-chain volume since 2018.

Circle’s USDC dominated the stablecoin market in July, accounting for nearly 50% of the total volume. USDC transactions reached approximately $748 billion. Tether’s USDT, the largest stablecoin by circulating supply, followed with a volume of $420 billion. The decentralized DAI stablecoin secured the third spot with $261 billion in transactions.
The increase in stablecoin volume in July can be attributed to several factors. The record performances of Bitcoin and Ethereum last month, with Bitcoin reaching a new all-time high of over $123,000 and ETH approaching the $4000 threshold, spurred significant on-chain activity. Investors sought non-volatile digital assets like USDT and USDC to park their profits.
Moreover, the stablecoin industry received a boost with the approval of the GENIUS Act in the US. Signed into law on July 19, this bill established clear guidelines and regulations for stablecoins and digital asset-backed financial products. The new regulations include reserve requirements and oversight by the Federal Reserve, bringing greater trust and stability to the sector.
Prominent financial institutions like JPMorgan and global companies like Meta have been exploring the use of stablecoins for cross-border transactions and other financial services, further legitimizing the market. With a clearer regulatory backdrop and increasing adoption, stablecoin market capitalization has surpassed $278 billion, according to CryptoSlate’s data.
Overall, the surge in stablecoin transaction volumes in July signals a maturing market with strong growth prospects. As the sector continues to evolve and gain mainstream acceptance, stablecoins are poised to play a crucial role in the future of finance.
