Polygon Open Money Stack brings bank payments to Solana businesses

Polygon Labs has brought its Open Money Stack to Solana, giving businesses a single connection for bank funding, digital wallets, cross-chain transfers and global payouts. The expansion, announced on October 29, 2026, links Solana stablecoin payments with banking services that can turn those transfers into money recipients can use.

Key takeaways

• Solana businesses can access banking and crypto payment channels through one integration.
• Kira is adopting the service for dollar-denominated supplier payments.
• Polygon’s Coinme acquisition provides U.S. payments coverage across 48 states.

How Polygon’s Open Money Stack connects Solana payments

Businesses can use the integration to accept supported bank and cryptocurrency payments, move funds across networks and pay customers or suppliers in their preferred currencies. Transfers can connect Solana with Polygon, Ethereum and TRON, following the platform’s earlier addition of TRON support.

Polygon Labs said the expansion reduces the need to manage separate payment providers and technical integrations. Businesses can link bank, card, cash and crypto funding channels, set up customer accounts and wallets, and send payouts through supported channels, all via a single API.

The infrastructure includes fiat conversion, custodial wallets, compliance tools and cross-chain routing. Developers can reach Solana without operating their own bridges or pre-funding liquidity on the destination network.

Kira connects stablecoin transfers with supplier payments

Kira is among the first customers adopting the Solana integration, using it to help fintechs, OTC desks and import brokers convert stablecoins into dollars for overseas supplier payments.

This fintech firm links U.S. banking infrastructure with stablecoin-based payments, enabling clients to hold dollar accounts, receive funds, manage stablecoin balances and settle payments with international suppliers.

Kira’s co-founder and CEO, Edrizio De La Cruz, noted that the company already relies on Solana for stablecoin transfers but requires banking integrations to move those funds to customers.

“Working with Polygon helps us turn those transfers into dollars in our clients’ bank accounts when they need to pay suppliers,” he said.

Alongside Tazapay, Mesh and Toku, Kira had earlier been named as one of the first customers of the Open Money Stack, following Polygon’s completion of its Coinme acquisition earlier in October. Initial applications include cross-border transfers and payroll, and Polygon anticipates that the expansion will also enable merchant payouts.

Banking coverage and blockchain settlement

With the Coinme deal, Polygon added 37 state money transmitter licenses and 11 applicable exemptions to its U.S. payments operation, extending its reach to 48 states.

The Polygon Open Money Stack merges regulated banking links with wallet services, crypto conversion and settlement across its supported networks, offering both public settlement on Polygon Chain and dedicated Polygon CDK rollups for firms needing tailored compliance or private infrastructure.

According to Polygon Labs, Polygon Chain has processed more than $3 trillion in total stablecoin transfers, with transactions finalizing in under two seconds and average fees around $0.002.

Polygon Trails further extends this cross-chain infrastructure; since August 3, 2026, this routing tool has enabled transfers of SOL, wrapped SOL, USDC, USDT and PYUSD between Solana and over 20 Ethereum-compatible networks.

Solana Foundation sees a wider payments reach

Connecting Solana to bank accounts and global payout networks would help businesses bring stablecoin payment services to more customers and markets, said Solana Foundation Chief Product Officer Vibhu Norby.

Norby stated that Solana’s stablecoin transaction volume exceeded $5 trillion throughout 2026. That figure covers activity during the year, while Polygon’s reported volume is cumulative.

“Polygon Open Money Stack provides another path for businesses to access these capabilities, complementing the infrastructure and payment solutions already available across the Solana ecosystem,” Norby said.

The Solana Foundation appointed Jamal Raees, a former Polygon Labs executive, as general manager of payments in September. He is responsible for engaging with payment firms and businesses looking to adopt Solana for their financial operations.
