Dune Analytics dashboards indicate a clear split in how the two largest U.S. dollar–pegged stablecoins are used: Tether’s USDT dominates everyday payments and transfers, while Circle’s USDC is more prevalent across decentralized finance (DeFi) protocols. The trend underscores how the choice of underlying blockchain influences stablecoin adoption and utility.
USDT Leads Payments Activity
USDT appears to be the primary stablecoin for value transfer, remittances, and exchange-related flows. Much of this activity occurs on Tron, a network favored for its low fees and fast settlement. The combination of broad exchange support and low-cost transfers has made USDT a default option for peer-to-peer payments and cross-border transactions in many markets.
USDC Anchors DeFi Liquidity
USDC is more embedded in DeFi, particularly on Ethereum and its layer-2 networks. It is widely used as collateral in lending markets, as a base asset in decentralized exchanges, and in liquidity pools. Deep integrations with DeFi protocols and tooling have reinforced USDC’s role as a preferred unit of account and settlement asset within on-chain financial applications.
Network Effects Shape Stablecoin Use
The divergence reflects network characteristics and ecosystem depth. Low transaction costs and broad exchange integration have steered payments toward USDT, while Ethereum’s mature DeFi stack favors USDC. As both assets remain multi-chain, their respective strengths—payments for USDT and DeFi for USDC—highlight how fees, speed, and application ecosystems guide stablecoin utility across blockchains.
