$USDT commands the largest market cap in stablecoins, while Circle's $USDC sits at roughly $73 billion to $75 billion in circulating supply. On paper, that looks like a straightforward win for Tether. Onchain, the story is very different.
According to Token Terminal data, USDC moved $3.2T in transfer volume over the past 30 days, compared to $1.3T for USDT. Total stablecoin and tokenized asset transfers reached $6.5T across nearly 3,500 assets in the period. The gap points to something more structural than a short-term shift in trader preference.
USDC leads in high-volume settlements, while USDT dominates small-value transfers and offshore USD demand. That division of labor has been building for some time. Dune data shows USDC has become the preferred settlement layer for decentralized exchanges, lending protocols, and automated market makers, particularly on faster networks like Layer-2 chains and Solana. The institutional angle is also sharpening. According to CoinDesk, growing adoption by banks and financial institutions, including new USDC services from Standard Chartered and BNY, reflects a broader shift toward established fiat-pegged digital asset networks.
The divergence comes down to velocity. Each USDC dollar circulates more frequently than USDT across payments, DeFi, settlements, and cross-chain activity. USDT, by contrast, functions more like held digital cash, widely distributed across remittance corridors and emerging market wallets where users store value rather than transact repeatedly.
This shift stands in stark contrast to the recent past. In 2020, USDT accounted for nearly 90% of adjusted trading volume, while USDC was under 10%. By 2022, USDC's share had risen to approximately 45% and has continued to climb. Bloomberg reported that total stablecoin transaction volumes rose 72% to $33 trillion in 2025, with USDC accounting for $18.3 trillion of that total against USDT's $13.3 trillion.
The takeaway is not that USDT is losing relevance. Expect continued divergence, with USDC leading in adjusted and real-economic volume and institutional rails, while USDT maintains supply and retail dominance. Both are dollar stablecoins, but they are increasingly serving different corners of the financial system.
