Stablecoin Cards Still Rely on Visa and Mastercard
Stablecoin cards are emerging as a funding and settlement layer beneath traditional card networks rather than replacing Visa or Mastercard. Stablecoins such as USDC can move value 24/7, while card networks provide merchant acceptance, transaction authorization, fraud controls, refunds, chargebacks and bank connections.
A typical payment converts or reserves a user’s stablecoins before routing the transaction through Visa or Mastercard. Merchants can therefore accept payments without adding blockchain infrastructure. Visa said stablecoin-linked cards processed about $5.2 billion in 2025, up 319% year on year. Monthly crypto-card spending also reached roughly $600 million.
Visa and Mastercard are increasingly adopting stablecoin settlement themselves. Mastercard supports settlement involving USDC, PYUSD and RLUSD, while Visa has enabled USDC settlement for financial institutions, including through Solana. Rain has used USDC to support seven-day settlement for Visa card programmes.
The development strengthens the case for stablecoins in payments but does not remove the role of established card networks. Stablecoin issuers may gain reserve income, while Visa and Mastercard can continue earning from transaction routing and merchant acceptance. For crypto traders, the trend is a long-term adoption signal, although it is not an immediate price catalyst.
Neutral
The market impact is neutral because the article describes infrastructure development rather than a new token launch, regulatory decision or immediate change in supply and demand. The reported 319% annual growth in Visa stablecoin-card volume and approximately $5.2 billion processed in 2025 are positive adoption signals. They could support long-term demand for USDC and other payment-focused stablecoins, while improving confidence in blockchain-based settlement.
However, stablecoin cards still depend on Visa and Mastercard for merchant acceptance. This limits the direct disruption and reduces the likelihood of an immediate repricing across major cryptocurrencies. Stablecoins are generally designed to maintain a fixed value, so increased usage does not automatically create a speculative price catalyst. SOL could receive indirect attention because Visa’s settlement initiatives include Solana, but the article provides no evidence of a direct impact on SOL demand.
In the short term, traders may treat the data as modestly positive for payment and infrastructure narratives, particularly if card volumes continue rising or major issuers announce wider rollouts. Broader market direction, interest rates, regulation and stablecoin flows will likely remain more important price indicators. In the long term, stablecoin adoption could benefit payment networks, issuers and blockchain settlement providers. Similar adoption announcements in the past have typically produced narrative-driven gains, but sustained price effects required measurable transaction growth, new users and regulatory clarity.
