USDC Leads Crypto Card Spending as Top-Ups Reach $13.8 Billion

Stablecoins are moving from exchange‑centric uses toward everyday consumer payments. By August 2026, cumulative top‑ups to crypto‑linked cards using USDC and USDT hit $13.8 billion, an increase of nearly $10 billion over the previous year, according to Cryptorank data.

Stablecoins as Daily Payment Balances

USDC currently leads tracked card spending, while USDT is rapidly gaining share. This contrasts with the broader stablecoin market where USDT dominates total supply. The shift reflects USDC’s integration with fintech and payment infrastructure, and USDT’s strong presence on exchanges and in remittance corridors.

Multi‑Chain Settlement Landscape

Spending activity is spread across several blockchains. Base accounts for about $1.2 billion of tracked stablecoin card spending, followed by Solana ($635 million), Polygon ($544 million), and Optimism ($509 million). Other networks such as Arbitrum, Scroll, Ethereum, and Stellar also handle notable volumes.

Reliance on Traditional Payment Networks

Despite the blockchain funding layer, most crypto cards still depend on Visa or Mastercard, regulated issuers, and identity verification to complete merchant transactions. Competition now focuses on custody solutions, foreign‑exchange costs, rewards structures, and capital efficiency.

Future Outlook

The next challenge will be sustaining growth as cashback subsidies diminish. Continued expansion without aggressive incentives would demonstrate that stablecoins can serve as practical consumer money while leveraging existing payment rails.
