Mastercard has partnered with Chainlink to enable its three billion cardholders to buy Bitcoin and other digital assets directly on-chain via a non-custodial solution. The integration involves partners such as Shift4 Payments, Swapper Finance, and ZeroHash to ensure secure, compliant fiat-to-digital assets conversion. This move forms part of Mastercard’s growing commitment to digital assets — including digital asset debit cards and tokenising around 30% of its global transactions. Meanwhile, rival Visa is also expanding its Bitcoin and digital assets offerings.
