Polygon Labs has integrated Solana into Open Money Stack, a payments platform linking bank accounts, cryptocurrency transfers and payouts. Polygon said one integration lets businesses receive money from bank accounts, transfer funds across blockchains and pay recipients. The addition follows Solana's activation of the Alpenglow consensus upgrade a week earlier. Alpenglow reduced transaction finality to 150 milliseconds from about 12.8 seconds.
Polygon's statement identified Kira as one of the first customers using the Solana integration. Kira helps clients convert between dollars and stablecoins, make payments through banking systems and pay overseas suppliers. Kira CEO Edrizio De La Cruz said Kira already uses Solana for stablecoin transfers. De La Cruz said working with Polygon helps convert those transfers into dollars in clients' bank accounts when supplier payments are due.
Open Money Stack also links Solana to networks including Ethereum, Polygon and TRON. TRON joined the platform earlier this month. Polygon said businesses can use the platform to offer customer accounts and wallets and convert funds. Polygon said the platform also routes payments to supported bank accounts, cards, cash services and cryptocurrency wallets.
Dollar-pegged stablecoins continue to grow in transaction volume and usage. The Block's data dashboard puts total supply near $290 billion. The dashboard shows Tether's USDT leading with more than $182 billion, followed by Circle's USDC with nearly $76 billion.
Solana Foundation Chief Product Officer Vibhu Norby said Solana processed over $5.5 trillion in stablecoin volume during 2026. Norby said connections to bank accounts, wallets and global payout networks allow businesses to bring stablecoin payments to additional customers and markets as activity grows. Norby described Open Money Stack as an additional way for businesses to access those capabilities, complementing existing Solana infrastructure and payment services.
Polygon completed the Coinme acquisition earlier this month. The acquisition gave Polygon money transmission licenses and exemptions spanning 48 U.S. states.
