Rain is now a Mastercard Principal Member

Stablecoins are no longer on the fringe of global payments. The next wave is consumer spending and everyday business payments, and the infrastructure supporting that wave needs to be trusted, scalable, and global.

Today, Rain is announcing our Mastercard Principal Membership. This means that Rain can now offer credit and prepaid cards on the Mastercard network, giving our partners greater flexibility, control, and choice as they scale their stablecoin-powered payment programs.

What this means for our partners‍

Partners building global card programs need infrastructure that can meet them where their users are, and where their business is going. 

Rain's infrastructure stack was purpose-built for stablecoin card programs, not retrofitted from a fiat model, and allows programs to expand across geographies through a single integration rather than rebuilding market by market. Partners get to market faster, and scaling after launch is simpler. 

Mastercard is accepted by hundreds of millions of merchants across more than 210 countries and territories. That reach will now be available to Rain partners.

Settlement modernized behind the scenes‍

Beyond card issuance, Rain and Mastercard will explore settling select program flows onchain using regulated stablecoins. This matters because settlement can be capital-intensive and create operational constraints.

Traditional fiat models rely on fixed banking cut-off times and require partners to pre-fund several days of spending volume in reserve at all times, tying up liquidity and reducing flexibility. Rain’s infrastructure already supports daily settlement with card networks including weekends and holidays, cutting that collateral requirement significantly. Onchain settlement, once implemented, would take that further, supporting more frequent, always-on settlement while improving capital flow and keeping the cardholder experience exactly as it should be. 

From the cardholder’s perspective, nothing changes. Cards continue to deliver the familiar, secure, and globally accepted experience they’re expected to. Stablecoins do the work in the background – strengthening settlement and liquidity flows rather than altering the moment of payment itself.

Part of something bigger‍

This announcement builds on Rain's recent selection as a launch partner in the Mastercard Crypto Partner Program, which brings together innovators across the digital assets ecosystem to advance onchain payments. Through the program, and now as a Principal Member, Rain and Mastercard will collaborate to explore new integrations, co-develop payment capabilities, and expand real-world stablecoin use cases.

It also follows Rain's $250M Series C, which we raised to accelerate exactly this kind of work: network integrations, international expansion, and new products that make stablecoin payments work everywhere.

The bigger picture

Tokenized money is the next era of money. Stablecoins are moving from niche instrument to core infrastructure, and the world's largest payment networks are moving with them.

From day one, Rain has believed that tokenized money must be usable in everyday life. Becoming a Mastercard Principal Member is another step toward making that real.
