Polygon Labs expands Open Money Stack to Solana, adding bank and cross-chain payment tools

Polygon Labs has extended its Open Money Stack stablecoin payments infrastructure to the Solana network, offering businesses a single integration for bank account connections, cross-chain fund routing, and global payouts. The platform collapses the multi-provider complexity of crypto payments into one technical connection, supporting funding routes from banks, cards, and cash, as well as conversion and payouts across Polygon, Ethereum, and Tron. Cross-border payments firm Kira is among the first adopters, using the stack to convert stablecoin transfers into dollars for bank payouts. The move leverages Solana's growing payments volume, which exceeded $5 trillion in stablecoin transfers this year.
