Polygon has integrated Solana into its Open Money Stack, enabling USD and stablecoin transfers through a single API. The platform supports deposits, cross-chain transfers, and payments, with Kira among the first clients using the Solana integration for USD-to-stablecoin conversions. The update follows Solana’s Alpenglow upgrade, which reduced finality time to 150 milliseconds. Polygon has also acquired Coinme, securing money transmission licenses in 48 U.S. states. This move aligns with ongoing global crypto policy shifts and introduces new on-chain advancements for cross-chain payment innovation.

ChainCatcher reports that Polygon Labs has integrated Solana into its Open Money Stack payment platform, enabling enterprise customers on the network to connect directly to U.S. bank accounts and global payment networks through a single API framework. The platform supports enterprises in depositing funds from bank accounts, transferring assets across chains, and making payments to recipients, while also offering customer accounts and wallets, currency conversion, and routing payments to supported bank accounts, debit cards, cash services, and crypto wallets. Kira is among the first customers to utilize the Solana integration, helping clients convert between USD and stablecoins, send payments via banking channels, and pay overseas vendors. Kira’s CEO, Edrizio De La Cruz, stated that the company has already used Solana to transfer stablecoins, and its partnership with Polygon enables these transfers to be converted into USD within its customers’ bank accounts when payments to vendors are required. Open Money Stack also connects Polygon, Ethereum, and TRON, which was integrated earlier this month. This integration follows Solana’s activation of the Alpenglow consensus upgrade a week ago, which reduced transaction finality time from approximately 12.8 seconds to 150 milliseconds. According to data from The Block, the total supply of USD-pegged stablecoins has approached $290 billion, with USDT exceeding $182 billion and USDC nearing $76 billion. Solana Foundation’s Chief Product Officer, Vibhu Norby, noted that Solana processed over $5.5 trillion in stablecoin transactions in 2026. Earlier this month, Polygon also completed its acquisition of Coinme, gaining money transmission licenses and exemptions covering 48 U.S. states.
