Mastercard

The 60-year-old payments network has been experimenting with blockchain for much of the last decade and has recently put stablecoins at the core of its approach to crypto.

In March 2026, Mastercard agreed to acquire stablecoin infrastructure firm BVNK for up to $1.8 billion. Mastercard also helps a large number of customers in the crypto sector—including Binance, Gemini, and MetaMask—issue credit and debit cards. The service allows users to spend their digital assets like cash.
