Base Dominates Stablecoin-Linked Payment Cards with 19% Market Share

The stablecoin-linked payment card market has reached new heights, with monthly on-chain transaction volumes reaching $759 million in July 2026. This puts the annualized figure at around $18 billion. Base is emerging as a dominant force in this space, accounting for approximately 19% of all tracked crypto card spending volume.

This makes it one of the largest blockchain networks powering stablecoin-linked payment cards, putting it in a dead heat with Solana also at 19%. Optimism leads the pack at 29%. Visa's expansion of its stablecoin settlement pilot to include Base on April 29, 2026, was a key accelerator for this trend.

Visa now supports nine blockchains, and its stablecoin-linked card programs exceed 130 across more than 50 countries. The dominant assets flowing through these programs are USDC and USDT, the two largest dollar-backed stablecoins by market cap.
