USDC rises as on-chain payment rail amid stablecoin rules

On-chain activity tied to USDC increased in late 2025 and early 2026, with active ERC20 stablecoin addresses reaching about 600,000 before stabilizing near 425,000 across crypto networks.

On-chain data shows the rise reflected a growth in transactions for payments, settlements and liquidity movement rather than a simple increase in token supply.

The CLARITY draft separates payment-focused stablecoins from yield-bearing products offered through centralized intermediaries. Under the draft, payment stablecoins are treated as payment rails subject to rules aimed at preserving convertibility and stability. Tokens packaged with interest or yield would fall under investment-style oversight and additional controls for platforms that offer those returns.

Regulators and officials are refining digital-dollar infrastructure and related rules to bring stablecoins into existing financial frameworks, enabling banks, payment services and clearing networks to consider integrating stablecoin rails for cross-border transfers, corporate settlements and liquidity management.

Market participants point to USDC, the dollar-pegged token issued by Circle, as a primary beneficiary. Its ERC20 implementation and wide availability on exchanges and custodial services have led to frequent use for on-chain settlements and short-term liquidity placement.

The pattern of a sharp rise followed by stabilization around the mid-400,000s coincided with increased transactions tied to operational flows rather than speculative trading.

Under the separation in the CLARITY draft, payment stablecoins would face rules focused on preserving convertibility and stability, while yield-bearing products that promise returns would be subject to investment-style regulation and supervision.
