Rain, a stablecoin payments infrastructure company, is shifting the competitive focus for U Cards from simple issuance to user retention and repeated usage. On June 15, Rain launched "Rain Rewards," an embedded loyalty program capability within its card-issuing infrastructure. This allows partner businesses—like fintech platforms and neobanks—to configure branded loyalty points, earning rules, redemptions, and merchant promotions directly within their card products. The system, built from the 2025 acquisition of Uptop, ensures points are only issued upon final transaction settlement, preventing liabilities from refunds. Trials, such as with Avalanche Card, reportedly boosted spending by 25% among enrolled users.
Founded by Farooq Malik and Charles Yoo-Naut, Rain evolved from a tool for managing Web3 company expenses into a full-stack enterprise platform. It is a Principal Member of Visa and Mastercard, enabling partners to issue stablecoin-backed cards and wallets while leveraging traditional payment networks. Notably, the popular U Card Plasma One is issued by Rain under Visa's authority. Rain also integrates with Visa's stablecoin settlement pilot, using USDC for network settlement.
Rain's rapid funding reflects growing institutional interest in stablecoin payment infrastructure. It raised a $245 million Series A in March 2025, a $58 million Series B in August 2025, and a $250 million Series C in January of this year, reaching a $19.5 billion valuation. Annualized transaction volume exceeds $3 billion, serving over 200 partners including Western Union and Nuvei.
Beyond cards, Rain is expanding into programmable payments. Its June 2026 "Agent Control Layer" allows businesses to set spending rules—like merchant categories, amounts, and frequency—for AI agents before transactions occur. This positions Rain not as a single product but as an operating system for stablecoin payments, handling everything from card issuance and wallet management to rewards, on/off-ramps, and automated compliance. The goal is to enable seamless, often invisible, real-world spending of on-chain assets.
