Modern Treasury Integrates on Polygon to Support Stablecoin Payments

tl;dr: 

• Modern Treasury now supports USDC on the Polygon network, letting businesses move between Polygon and the U.S. financial system without managing separate systems for fiat and stablecoins
• Teams can convert USD to USDC and back, move funds with built-in compliance, and reconcile fiat and onchain activity in a single ledger
• Stablecoin payments sit alongside ACH, wires, RTP, FedNow, and push-to-card, no separate stack required
• Teams can launch stablecoin products in days, with compliance, accounts, and ledgering already in place

Modern Treasury today announced an integration with the Polygon network to support USDC. The integration helps more businesses move between Polygon and the U.S. financial system without managing separate systems for fiat and stablecoins.

Customers can now send, receive, and reconcile stablecoin payments alongside ACH, wires, RTP, and every other rail Modern Treasury supports, all through a single integration.

This is exactly what the Open Money Stack is built for. The Open Money Stack is our open and integrated set of services and technologies to move money instantly and reliably anywhere, and the Polygon network is its settlement layer. $2.4 trillion in stablecoin volume has already settled on it. But settlement alone doesn't move enterprise dollars. Enterprises move when the orchestration layer, the compliance tooling, the ledgering, and the on/off-ramps are already solved

That's what the Open Money Stack provides, and Modern Treasury, with over $400 billion in payments having moved through their infrastructure, is now part of it.

Stablecoin rails should fit where teams already work

Through this integration, Modern Treasury customers can convert USD to USDC and back through programmatic on- and off-ramps. 

This integration allows them to move funds on Polygon with built-in compliance and near-instant settlement, orchestrate payments across ACH, wires, RTP, FedNow, push-to-card, and stablecoin rails in a single system, and reconcile fiat and onchain activity through a unified ledger.

Those capabilities support real use cases: cross-border payouts, marketplace disbursements, treasury management, and real-time global fund movement.

Built in days, not months

We know one of the biggest barriers to stablecoin adoption is the integration tax. 

Teams that want to offer stablecoin-based products typically face weeks of work connecting wallets, compliance tools, ledgers, and on/off-ramps. 

By offering Polygon as a native rail within payments, Modern Treasury collapses that timeline. Teams can launch stablecoin products in days, with compliance, accounts, and ledgering already in place.

Polygon has processed trillions in value, making it one of the most proven networks for stablecoin payments. 

By integrating it into the Modern Treasury platform, teams can send, receive, and reconcile stablecoin payments as easily as any other payment method.

How Polygon’s Open Money Stack enables this integration

This integration is a concrete example of how we're building the Open Money Stack.

OMS is an open and integrated stack of services and technologies to instantly and reliably move money anywhere, and put it to work. 

Modern Treasury exemplifies why the OMS matters for real-world use cases: the orchestration, compliance, and ledgering layer that enterprises need before they'll move a dollar through any new rail. Polygon Chain handles settlement. Modern Treasury handles operations. 

Businesses building on top don't have to think about either.

Already running at enterprise scale

$2.4 trillion in stablecoin volume has settled on Polygon Chain to date, on a network that has maintained 99.999% uptime over five years, processes an average of 6 million transactions per day, and settles in roughly two seconds at an average cost of $0.0008 per USDC transfer. 

In March 2026 alone, Polygon processed 178 million USD stablecoin transactions, capturing over 22% of global market share.

Revolut has moved more than $1.2 billion in stablecoin transfers through Polygon Chain, with fees that are 426x cheaper than Ethereum and 4x cheaper than Solana. Mastercard integrated Polygon for username-based transfers across self-custody wallets. Tazapay, a B2B cross-border payments platform operating in 173 countries, processed $687 million on Polygon in a single month. Paxos crossed $1.3 billion in volume, representing 50x growth in twelve months.

When institutions at this scale put live payment volume on a network, they've done the work. Modern Treasury's customers are joining infrastructure that's already proven.
