Rain
Rain enables platforms to embed stablecoin payments through Visa-compatible infrastructure.
Rain is a full-stack fintech infrastructure platform that enables developers, fintechs, and financial services firms to embed stablecoin payments into their products through a unified API. The platform handles money-in, storage, spending, and money-out across multiple blockchains while managing complex back-end operations like tokenization, compliance, and settlement. Rain's proprietary settlement stack allows Visa card transactions to interoperate with stablecoins, making them practical for everyday purchases. The company pioneered the ability to settle Visa transactions using stablecoins seven days a week, reducing working capital requirements and enabling near-instant liquidity.
Problem solved
Stablecoins remain impractical for everyday spending because most merchants don't accept them directly and consumers lack the card convenience, fraud protections, and rewards they expect from traditional payment methods.
Target customer
Fintech platforms, payment processors, financial services firms, and developers building consumer and B2B payment solutions seeking to integrate stablecoin functionality at scale.

Competitors
Bridge (Stripe)
Broader payments infrastructure platform acquired by Stripe in February 2025; expanded Visa partnership to 100+ countries but less focused on stablecoin-specific settlement capabilities.
Why this matters: Rain is the first company to enable Visa transactions to settle using stablecoins seven days a week, solving a critical liquidity and settlement problem for fintech platforms. With $338M raised and a $1.95B valuation as of January 2026, Rain is positioned as the infrastructure layer for the stablecoin payment era—comparable to Stripe's role in online payments.
Best for: Fintech platforms, payment processors, and developers who need to offer stablecoin-based payment cards that function on the Visa network while managing multi-chain complexity.
Use cases
Merchant Payouts with Stablecoins
Payment processors like Nuvei use Rain to issue stablecoin-backed payout cards, enabling merchants to receive payments in stablecoins and spend them immediately at any Visa-accepting merchant. This eliminates conversion delays and reduces working capital needs.
Cross-Border Payroll
Companies use Rain's infrastructure to pay remote international employees in stablecoins via Visa cards, avoiding traditional wire delays and international payment friction. Employees can spend the stablecoins anywhere Visa is accepted or convert locally.
Corporate Expense Management
B2B platforms like Ramp competitors can embed Rain's technology to issue stablecoin-funded corporate cards that tap into liquidity pools, track spending, and settle instantly rather than waiting for traditional card settlement cycles.
State-Issued Stablecoin Real-World Spending
Rain partnered with Wyoming and Avalanche to launch Frontier Stable Token (FRNT), enabling citizens and businesses to spend Wyoming's state-issued stablecoin through Rain-issued Visa cards at everyday merchants.
Alternatives
Bridge
Broader Stripe-backed payments infrastructure; better if you need multi-currency and traditional payment rails alongside stablecoins.
Stripe
General payment infrastructure for online and in-person; lacks stablecoin settlement and blockchain interoperability.
Brex
Corporate card and expense management platform; doesn't offer stablecoin-native settlement or multi-chain capabilities.
FAQ
What does Rain do? +
Rain provides full-stack fintech infrastructure that enables developers and platforms to embed stablecoin payments into their products through a single API. The platform handles money movement (in, out, storage, spending) across multiple blockchains while managing settlement, compliance, and authorization. Rain's key breakthrough is enabling Visa card transactions to settle using stablecoins seven days a week, eliminating traditional settlement delays and working capital requirements.
How much does Rain cost? +
Pricing is not publicly available. Rain likely uses a fintech infrastructure model combining interchange fees on card transactions and subscription fees for expense management features, similar to competitors Brex and Ramp. Contact Rain directly for pricing details.
What are alternatives to Rain? +
Bridge (Stripe's acquisition) offers broader payments infrastructure but less stablecoin focus. Stripe provides general payment processing without blockchain settlement. Brex specializes in corporate cards and expense management without stablecoin capabilities. For traditional card programs without crypto, look at Marqeta or Galileo.
Who uses Rain? +
Rain serves fintech platforms, payment processors, financial services firms, and developers building consumer and B2B payment solutions. Notable customers include Western Union, Nuvei, KAST, Avalanche, and state governments like Wyoming. The platform facilitates over $3B in annualized transactions for more than 200 partners.
How does Rain compare to Bridge? +
Rain is stablecoin-native with proprietary multi-chain settlement technology and Visa Principal Member status, enabling instant settlement 24/7. Bridge is a broader payments platform acquired by Stripe with wider traditional payment rail coverage. Rain is best if stablecoin payments and working capital reduction are priorities; Bridge if you need comprehensive payment infrastructure across multiple channels.
