USDT Leads Stablecoin Payments While USDC Dominates DeFi, Dune Data Shows

Dune data shows a widening split in stablecoin usage, with Tether’s USDT emerging as crypto’s dominant payments stablecoin while Circle’s USDC continues to power decentralized finance. The divergence points to a market where the largest stablecoins are not simply competing on size, but increasingly serving different roles.

The development matters because stablecoins are a core part of crypto market infrastructure, used for transferring value, trading, and interacting with onchain applications. If USDT is winning payments while USDC is gaining strength in DeFi, it suggests users and companies may be choosing stablecoins based on the blockchain environments and use cases that best fit their needs.

USDT’s role in payments reflects its broad use as a dollar-linked digital asset for moving value across crypto networks. USDC’s position in DeFi, meanwhile, underscores its importance in protocols and applications where stable liquidity is central to onchain activity.

The Dune data also highlights the importance of blockchain choice. Different networks can influence transaction costs, speed, accessibility, and the kinds of applications users rely on, helping explain why stablecoin activity can fragment by use case rather than converge around a single asset.

For the crypto ecosystem, the split reinforces that stablecoins are becoming more specialized. Rather than one token dominating every category, USDT and USDC appear to be carving out distinct roles across payments and DeFi, shaping how users interact with digital dollars onchain.
