Ethereum has reclaimed its position as the primary network for USDT supply, reaching $80 billion and surpassing Tron after falling behind earlier in March. This reversal represents a significant shift in stablecoin infrastructure preferences, with both networks maintaining relatively stable supply levels around $75-$80 billion throughout most of 2025. The close competition between these networks highlights the ongoing shifts in settlement dominance, with marginal advantages potentially driving substantial liquidity migrations.
The redistribution of USDT supply reflects evolving user preferences for blockchain infrastructure, particularly as traditional finance increasingly adopts stablecoin rails. Ethereum's resurgence suggests that users are prioritizing the network's established DeFi ecosystem and institutional-grade infrastructure over Tron's lower transaction costs. Daily stablecoin transfers on Ethereum have reached nearly 1 million transactions per day, indicating not just static holdings but active utilization of USDT for payments and settlements.
This shift occurs as traditional financial institutions increasingly integrate stablecoins into their payment infrastructure. Companies like PayPal with PYUSD and other traditional finance players are incorporating stablecoins into their existing rails, favoring Ethereum's more established institutional presence. The growing institutional adoption of stablecoins suggests that network effects and regulatory clarity will continue to be the main drivers of innovation and adoption.
The competitive dynamics between blockchains for stablecoin dominance carry broader implications for blockchain ecosystem development. The presence of large stablecoin volumes, such as USDT, influences cross-chain bridge activity, exchange integration strategies, and overall DeFi liquidity concentration. Ethereum's advantage in capturing institutional stablecoin flows could reinforce its position as the primary settlement layer for sophisticated financial applications, particularly as traditional finance continues to explore blockchain-based payment solutions.
