Polygon Labs announced on October 29, 2026, that it has expanded its Open Money Stack payment infrastructure to the Solana network. The move gives companies building on Solana a single technical integration and commercial relationship to connect traditional banking services with cryptocurrency rails, digital wallets, cross-network transfers and payout channels.

The expansion allows businesses to remain on Solana while accessing Polygon’s infrastructure for funding, conversion and settlement. Companies can adopt the full suite or select individual components to work alongside existing systems. Supported funding options include bank transfers, cards, cash services and cryptocurrency. Once funds enter the platform, they can be routed between Solana and other networks such as Polygon, Ethereum, TRON and several Ethereum Virtual Machine-compatible chains, with payouts delivered to banks, cards, cash outlets or wallets.

Single Integration for Bank-to-Crypto Flows

Open Money Stack is designed to simplify the multi-provider complexity that often accompanies crypto payments. Moving money from a bank account into a wallet, converting assets and returning funds to a recipient’s bank account has typically required separate integrations. The platform consolidates these steps, handling routing, asset conversions and transaction execution on the backend so users do not need to interact directly with bridges.

Practical applications include remittance firms collecting dollars from a customer’s bank account, transferring USDC over Solana and arranging a local bank payout abroad, or online marketplaces accepting stablecoin payments on Solana and distributing earnings to sellers via crypto wallets or local currency services.

Marc Boiron, CEO of Polygon Labs, said the decision responds to customer demand and the concentration of liquidity on preferred networks. Enterprises, he noted, place greater value on executing transactions where funds are already available than on the specific network used. The platform provides quoted all-in pricing before execution to lock in costs related to foreign exchange and cross-chain movement, reducing post-trade unpredictability.

Early Adoption by Kira and Regulatory Backdrop

Kira, a fintech firm that connects U.S. banking services with stablecoin payments, is among the first companies adopting the Solana integration. The company serves fintechs, over-the-counter desks and import brokers that need to convert stablecoin transfers into dollars for international supplier payments. Clients can open U.S. dollar accounts, manage balances and settle overseas obligations through supported bank rails.

Kira was previously listed among early Open Money Stack customers, alongside firms such as Tazapay, Mesh and Toku, following Polygon’s completion of its Coinme acquisition earlier in October. That deal brought 37 state money transmitter licenses and 11 applicable exemptions into Polygon’s U.S. payments business, providing coverage across 48 states. The acquisition strengthened the regulated banking connections that underpin the stack’s ability to link fiat funding with crypto settlement.

The Solana addition follows the October 8 expansion of Open Money Stack to TRON, which introduced support for USDT deposits, wallet management and transfers between TRON and compatible networks. Polygon Trails, a routing service within the infrastructure, has supported transfers of assets including SOL, wrapped SOL, USDC, USDT and PYUSD between Solana and more than 20 Ethereum-compatible networks since August.

Stablecoin Volumes Underscore Demand

The timing coincides with substantial stablecoin activity on Solana. Solana Foundation Chief Product Officer Vibhu Norby stated that the network processed more than $5 trillion in stablecoin transaction volume during 2026. Token Terminal data cited in reports put the figure at approximately $5.76 trillion from January 1 to October 27. By comparison, TRON recorded about $6.94 trillion in stablecoin transfers over the same period.

Polygon Chain, which serves as a settlement network within Open Money Stack, has processed more than $3 trillion in cumulative stablecoin transfer volume, according to Polygon Labs. Transactions on the chain finalize in under two seconds with average fees around $0.002.

Solana has also advanced its own institutional payments efforts. In September the Solana Foundation appointed Jamal Raees, a former Polygon Labs executive, as general manager of payments to engage payment companies and enterprises interested in using the network for financial transactions. The network has introduced an institutional settlement standard developed with input from major financial institutions and completed a significant protocol upgrade.

Polygon Labs continues to position Open Money Stack as a multi-network payments layer that combines regulated banking access with digital wallets, conversions and cross-chain settlement. The Solana integration expands the addressable set of businesses that can use the infrastructure without relocating their existing products or customers.
