Polygon Labs expands Open Money Stack payment infrastructure to Solana

Polygon Labs announced on October 29, 2026, the expansion of its Open Money Stack infrastructure to the Solana blockchain network. The integration allows businesses to link bank funding, digital wallets, cross-chain transfers across EVM, TRON, and Solana networks, and US bank payouts through a single connection. The move leverages Solana's more than $5 trillion in 2026 stablecoin volume and follows Polygon's acquisition of Coinme, which provided regulatory coverage across 48 US states. Cross-border firm Kira is among the first to adopt the system for supplier payouts.
