Stablecoin payments platform Rain just crossed a major milestone—the company's latest funding round valued it at nearly $2 billion. The Series C raise brought in $250 million, signaling strong investor confidence in the stablecoin payment infrastructure space. This valuation jump reflects growing market recognition that blockchain-based payment solutions are becoming essential infrastructure. The move comes as stablecoin adoption accelerates across businesses seeking faster, cheaper settlement options compared to traditional banking rails. Rain's momentum highlights how payment innovation is increasingly pivoting toward on-chain rails, particularly for enterprises looking to streamline cross-border transactions and reduce friction in their financial operations.
