Polygon Labs Brings Open Money Stack to Solana After Tron Rollout

Polygon Labs has extended its Open Money Stack to Solana, giving businesses building on the network a single integration for bank-account funding, customer wallets and global payouts. The move follows the stack's rollout to Tron earlier in October and Polygon's completed acquisition of the US payments firm Coinme.

Open Money Stack is Polygon's suite of services connecting bank accounts, crypto wallets and payout networks. Until now it was available for eligible uses on Polygon, Ethereum and other Ethereum Virtual Machine (EVM) chains. The Solana expansion marks the product's first push beyond EVM territory, and Tron's earlier this month was the second.

Why Solana, and why now?

Customer demand and stablecoin volume drove the decision, Polygon Labs CEO Marc Boiron told Cointelegraph. The numbers back him up. Solana recorded roughly $5.76 trillion in stablecoin transfers between Jan. 1 and Oct. 27, according to Token Terminal data, while Tron handled $6.94 trillion over the same window.

"As that activity grows, connecting Solana to bank accounts, wallets and global payout networks allows businesses to deliver stablecoin payments to more customers and markets," said Vibhu Norby, chief product officer at the Solana Foundation.

What does the new integration actually cover?

Polygon's Trails service has handled transfers between Solana and Ethereum-compatible networks since August. The latest expansion layers the full payments stack on top of that bridge:

• Bank, card and cash funding
• Customer accounts
• Embedded wallets
• Payouts

All of it arrives through the same integration, Boiron said.

The pitch targets a real operational headache. "We hear from businesses that their customers and payment activity are already spread across networks and that they don't want to force a chain choice or stitch together a bank provider, wallet, routing service and payout partner for each one," Boiron said.

Who is using it?

Kira, which provides US dollar accounts and stablecoin-based cross-border payment services to businesses, is among the first customers on the Solana integration, Boiron said. The addressable market is sizable: ecosystem data provider The Grid cataloged 478 companies and 261 projects in the Solana ecosystem last year.

The regulatory footing underneath

The Solana rollout follows Polygon's completed acquisition of Coinme, which handed its US payments business 37 money transmitter licenses and 11 state exemptions — coverage spanning 48 states. That license stack gives Polygon a regulated on-ramp structure for dollar-linked payment flows inside the United States, a prerequisite for the bank-account connectivity the Open Money Stack depends on.

For Solana-native businesses, the practical consequence is simpler plumbing: one integration replaces a patchwork of banking providers, wallet infrastructure and payout partners. For Polygon, the multi-chain posture positions Open Money Stack as chain-agnostic payments infrastructure rather than a tool for its own network alone.

With Tron and Solana both live and a licensed US payments business in place, the next marker to watch is whether the stack adds further non-EVM networks — and whether stablecoin transfer volumes, now running near $13 trillion combined across the two new chains this year, keep justifying that expansion.
