    When we started Rain four years ago, it wasn’t obvious how transformative stablecoins would be for global financial rails. By the time we raised our Series A a few months ago, it was clear that 2025 would be a breakout year but even we were surprised by the growth and demand

    Rain is about more than just making stablecoins spendable. It’s about rebuilding the existing financial infrastructure piece by piece, using modern rails that are more global, open, and efficient. That’s why I’m excited to share what we’ve been working on with @Visa .

    Startups building the future of finance need faster, more efficient payment rails. Rain is partnering with @Visa to settle fully onchain — unlocking 24/7 USDC settlement and tokenized credit receivables. This sets a new standard for payments in the digital asset economy.
