Stablecoin Card Spend Remains Under 1% of Global Total Despite Reported 105% Growth

Rain and Mastercard are exploring on-chain settlement for some card program flows using regulated stablecoins. Stablecoin settlement enables weekend and holiday settlement, reducing trapped capital by more than 40 percent in some cases. Traditional card programs often need to pre-fund network obligations or borrow from networks when banking rails are closed.

Stablecoins can move outside bank cut-off times. Rain is trying to make stablecoin balances usable through existing networks that already reach merchants globally. “The card networks over decades have rolled up hundreds of millions of merchants,” Timoney said.

Mastercard has been moving deeper into stablecoin payments. Earlier this year Binance, PayPal and Ripple joined Mastercard’s broader blockchain payments push. 8 billion.

Christian Rau, Mastercard’s senior vice president of digital assets and blockchain, said mainstream adoption will depend on making the technology invisible to consumers. “The normal benchmark these days is you have a card sitting on your iPhone or on an Android. You tap it, the money is gone,” Rau said.

The MetaMask Card was developed with Mastercard and Baanx. The MetaMask Card lets users spend from a self-custodial wallet while assets are converted into fiat at the time of purchase. Hernandez said the next stage depends on easier on-ramps, abstracted network fees and more local payment infrastructure.

Today’s crypto card users are still mostly crypto-native consumers who already hold assets on-chain. That view drew a challenge from Mark Zalan, CEO of GoMining, who argued that stablecoins and card infrastructure add unnecessary intermediaries to crypto payments. Zalan said users want to hold bitcoin in self-custody and spend it without converting into stablecoins or relying on off-ramps.

Timoney pushed back, saying payments are not only money movement. Card networks also handle chargebacks, merchant risk and other protections consumers and merchants expect. Rau made a similar point. Most consumers were “socialized with deposit insurance” and chargeback protection, he said.

“Payment is more than moving money from A to B,” Rau said.
