Open Money Stack Now Live on Solana
Polygon announced October 29 that Solana wallets are now live on its Open Money Stack, a payment infrastructure that links bank accounts directly to stablecoin transactions. The integration enables Solana users to fund wallets from bank transfers and withdraw stablecoins back to bank accounts without navigating a separate exchange. Solana Foundation President Lily Liu responded to the announcement with a post stating the network was "unblocked and unmuted" on the platform.
Expansion Following Acquisitions and Prior Chain Integrations
The Solana rollout represents Polygon's third major chain integration for the Open Money Stack. Tron received support earlier in the year, and Polygon itself was the first chain connected to the infrastructure. Polygon's October acquisition of Coinme, a cryptocurrency platform with established banking relationships, provided the on- and off-ramp infrastructure necessary to enable the bank-to-wallet and wallet-to-bank flows now available on Solana.
How It Works
Users on Solana can now deposit USD or other fiat currencies directly into compatible wallets, receiving stablecoins without touching a centralized exchange. Withdrawals follow the same path in reverse. The stack is built on Polygon's existing infrastructure but routes transactions through Coinme's banking partnerships, which handle the actual fiat movement.
Why It Matters
For Traders
Direct fiat on- and off-ramps reduce friction for Solana entry and exit, potentially lowering bid-ask spreads on DEX trading pairs and making spot purchases more competitive.
For Investors
Multi-chain payment infrastructure reduces Polygon's own chain dependency while establishing Coinme as a critical banking bridge; this signals Polygon's strategy to become infrastructure rather than just a scaling solution.
For Builders
Developers on Solana can now build payment and payroll products that settle directly to bank accounts without custom banking integrations, lowering the cost to ship fintech-grade DApps.
