Rain has joined the ranks of Mastercard Principal Members, empowering the firm to issue credit and prepaid cards on the Mastercard network for stablecoin-based payment programs.
This move grants Rain’s partners access to Mastercard’s extensive merchant acceptance footprint across over 210 countries and territories via a unified integration process.
The partnership aligns with Rain being chosen as an initial collaborator in the Mastercard Crypto Partner Programme, aimed at enhancing on-chain payment functionalities within the broader digital assets landscape.
Enhancing stablecoin card infrastructure
Rain’s card system was purpose-built for stablecoin programs rather than repurposing existing fiat models. The company claims this design allows partners to swiftly expand their offerings across different regions with minimal technical complexity, compared to market-by-market deployment.
As a Principal Member, Rain now offers both credit and prepaid card options through the Mastercard network, providing increased flexibility for partner programs.
The firm also secured USD 250 million in Series C funding, earmarked for network integrations, international expansion particularly into Asia-Pacific regions, and innovation within the stablecoin payments domain.
Exploring on-chain settlement
Beyond card issuance, Rain and Mastercard are considering implementing on-chain settlement using regulated stablecoins for certain payment flows. This approach is driven by the desire to mitigate capital and operational challenges inherent in traditional fiat-based settlement methods.
Under current practices, partners must preload substantial reserves well ahead of their actual spending needs, leading to significant liquidity constraints. Rain’s infrastructure already supports daily settlements with card networks, including weekends and public holidays, which substantially reduces collateral demands relative to conventional models.
An on-chain settlement system would further enhance this by enabling more frequent and continuous payment cycles. For customers, the transaction process remains seamless; however, stablecoin transactions handle backend operations without altering how payments are initiated or processed at the point of sale.
Rain’s role in the stablecoin ecosystem
The announcement underscores a broader trend where established financial networks like Mastercard are increasingly integrating digital assets into their core offerings. Stablecoins are evolving from crypto-specific tools to more mainstream settlement and liquidity solutions within traditional financial infrastructures.
With dual memberships as both a Mastercard Crypto Partner Programme participant and now a Principal Member, Rain is positioned at the heart of this collaborative ecosystem. The partnership will facilitate new integrations and jointly developed payment capabilities under the broader programme framework.
The Principal Membership represents a pivotal milestone for stablecoin-centric infrastructure providers like Rain, offering direct entry into the Mastercard network without reliance on sponsored members. This status carries significant implications for program governance, speed to market, and scalability for Rain’s partners.
