Base Now Handles 19% of Stablecoin Card Spend as Visa Pilot Hits $7B

Coinbase's Base network now processes roughly 19% of all tracked crypto card spending, putting it in a dead heat with Solana as Visa's stablecoin settlement pilot reaches a $7 billion annualized run rate.

Monthly on-chain volumes for crypto card programs hit about $759 million in July 2026, with nearly 9 million individual purchases recorded. Annualized, that puts the stablecoin card market in the neighborhood of $18 billion.

Visa has been the main accelerator. On April 29, 2026, the payments giant expanded its stablecoin settlement pilot to include Base, bringing the total number of supported blockchains to nine. After that expansion, the pilot reached the $7 billion run rate.

Visa's stablecoin-linked card programs now exceed 130 across more than 50 countries. USDC and USDT, the two largest dollar-backed stablecoins by market cap, dominate the flows.

Optimism leads the pack at 29% of tracked card spend, with Base and Solana each at 19%.

Base's appeal to card issuers comes down to low fees, fast finality, and native USDC support. Transaction fees on Base typically run a fraction of a cent, which matters when processing millions of small-ticket purchases per month. The network's optimistic rollup architecture delivers confirmations quickly enough to meet traditional payment rail expectations.

Circle, which issues USDC, has deep integration with Base. That isn't surprising given Coinbase is both a Circle investor and the operator of Base. The relationship means USDC minting, redemption, and settlement on Base are first-class operations, and issuers don't face liquidity gaps when users spend at checkout.

Visa's decision to support nine blockchains rather than picking a single winner suggests the company is hedging its bets. The multi-chain approach gives issuers flexibility but means no single network holds a monopoly on Visa's stablecoin volume.

Mastercard has been making its own stablecoin moves, most recently testing a single-audit compliance tool with Borderless.xyz. The competitive picture keeps shifting as both networks race to capture the settlement layer for card payments.

Base's Alpha Score sits at 64/100, labeled Moderate, reflecting the network's solid but not dominant position in the broader crypto infrastructure race.
