Stablecoins are no longer moving as one generic category. Cointelegraph reported on July 7 that Dune data showed Tether’s USDT leading identified onchain commerce payments, while Circle’s USDC remained stronger in decentralized finance and trading activity. For traders, the important point is not simply which token is larger, but which rail is liquid for the use case in front of them.
The reported split is meaningful because payment flow and trading flow create different types of risk. Payment-heavy stablecoins need broad wallet support, low transfer cost, reliable settlement and strong exchange deposit coverage. DeFi-heavy stablecoins need deep pool liquidity, lending-market integration, collateral acceptance and reliable redemption assumptions. A token can be useful in one lane without being the best choice in the other.
Cointelegraph cited Dune’s Digital Asset Brief showing USDT at about $95 billion of identified commerce payments in the first half of 2026, compared with about $14 billion for USDC, and roughly 92% of business-to-business payment volume. It also noted that USDC processed large transfer volume on Base and Ethereum, underscoring its role in trading and DeFi infrastructure.
That matters for exchange users moving funds between platforms. A trader focused on deposits, withdrawals and OTC-style transfers should compare supported networks, confirmation times, minimum deposits, fees and whether the receiving venue credits that exact asset-network pair. A DeFi user should additionally check pool depth, bridge risk, smart-contract risk and whether the protocol treats the stablecoin as prime collateral or secondary collateral.
The market signal is that stablecoin dominance may increasingly be segmented by workflow rather than by headline market capitalization. USDT can remain the preferred settlement instrument for many payment corridors, while USDC can still be the more natural quote or collateral asset in parts of Ethereum, Base and other DeFi ecosystems. That segmentation can make spreads and withdrawal congestion behave differently across chains.
For active traders, the practical checklist is straightforward: avoid assuming that all dollar stablecoins are interchangeable, verify the exact network before sending funds, keep small test transfers for new addresses, and maintain more than one funding rail when trading across centralized exchanges and onchain venues. The stablecoin with the tightest spread on one venue may not be the cheapest withdrawal route on another.
