Solid Partners with Rain to Power the Next Era of Global Crypto Cards
Stablecoin adoption is accelerating but the infrastructure connecting it to real-world spending is only now catching up.
At Solid, we've always believed the future of finance should be simple: earn yield seamlessly, spend it just as seamlessly, and never give up control of your funds.
Today, we're taking a major step toward that future.
We're partnering with Rain, one of the fastest-growing stablecoin card infrastructure providers in the world, to power the next generation of the Solid card.
Why Rain
Bringing crypto into everyday spending isn't just about issuing a card. It requires global compliance coverage, reliable payment rails, seamless user onboarding, and infrastructure that can scale across regions.
That's exactly where Rain stands out.
Founded in 2021, Rain has rapidly emerged as the backbone for stablecoin-native payment experiences. As a Visa Principal Member, Rain today powers over 200 partners globally facilitating more than $3B in annualized transactions. In the last year alone, their active card base grew 30x and annualized payment volume grew 38x. In January 2026, they closed a $250M Series C at a $1.95B valuation, backed by ICONIQ, Sapphire Ventures, Dragonfly, Bessemer, Galaxy Ventures, and Lightspeed.
The numbers reflect a simple reality: Rain isn't experimenting with crypto cards. They're building the category.
What Makes Rain Different
Most card infrastructure was built for fiat, with stablecoins bolted on after the fact. Rain was built natively for stablecoins from day one, and that distinction matters.
Rain's proprietary settlement stack settles directly with Visa in USDC, 7 days a week, 365 days a year. Their platform supports multi-chain settlement and it's all wrapped in enterprise-grade compliance, SOC 2 certified, regularly audited, and built to meet global regulatory standards across every market they operate in.
A Shared Vision
This partnership isn't just about expanding availability. It's about aligning with an infrastructure partner that shares the same conviction:
- Crypto should work globally
- Payments should feel instant
- Users should stay in control of their funds
Together with Rain, we're building toward a system where your stablecoins don't need to be off-ramped, converted, or manually moved just to be useful. They should simply work.
What This Unlocks for Solid
By integrating Rain's infrastructure, Solid is entering a new phase:
- A significantly more global card program
- Improved onboarding and reliability
- A stronger foundation for future features
With Rain, Solid can reach over 2.5 billion people across Latin America, Africa, Asia, the Middle East, and beyond, moving closer to what we've always been building toward: truly borderless finance.
What Comes Next
This is just the beginning. In a follow-up post, we'll go deep on what this partnership unlocks for Solid card users: the full country list, card perks, fee structure, and how to get yours.
For now, this marks a key milestone: Solid is powered by infrastructure built for global scale.
The next wave of crypto adoption won't come from better wallets. It will come from better products that integrate earning and spending into one seamless experience. That's what we're building at Solid. With Rain, we now have the infrastructure partner to make it truly global.
