USDC Turns Over 10 Times Faster Than USDT On-Chain Despite USDT’s Much Larger Supply
A Coin Metrics analysis says the key split between USDC and USDT is not just supply, but how often each dollar moves. In 2026, USDC’s annualized turnover on adjusted supply reached 741x, versus 74x for USDT, even though USDT’s market cap remained more than $100 billion larger. Year to date, adjusted stablecoin transfer volume totaled $41.7 trillion, with USDC accounting for $32 trillion, or 77% of the market, and USDT at $8 trillion, or 19%. The report argues that most headline stablecoin volume still comes from internal crypto-market activity rather than consumer payments. On Base, USDC transfers were heavily concentrated in a few contracts, led by DEX liquidity rebalancing and flash-loan activity. On Ethereum, USDC volume leaned even more toward flash loans, while Ethereum-based USDT showed a larger share of exchange-related flows. Tron presented a different pattern: little visible DeFi-driven turnover, a notable exchange-transfer share, and the largest bucket of unclassified activity, which the report says likely includes remittances and payment use cases. The breakdown offers a chain-by-chain view of what is actually driving trillion-dollar stablecoin flows across crypto infrastructure.
