Stablecoins have been promising faster, cheaper, and more efficient payments for years.
The concept of challenge has never existed before. It was infrastructure.
While blockchain networks can handle huge amounts of transactions under normal circumstances, many networks still suffer from unpredictable fees and performance bottlenecks when demand spikes. For businesses that process payroll, remittances, cross-border remittances, or B2B payments, that uncertainty creates problems that finance teams simply cannot accept.
Polygon believes they have solved it.
The company announced that Polygon Chain, the payments layer that powers the Open Money Stack, can now process up to 5,000 payment transactions per second with a network upgrade that significantly increases throughput while maintaining low and predictable fees.
This milestone puts Polygon in the same performance conversation as major global payment networks, while maintaining the benefits that made stablecoins attractive in the first place: near-instant payments, programmable transactions, and significantly lower costs.
Stablecoin opportunities continue to grow
The announcement comes as stablecoins continue their rapid transition from crypto-native tools to mainstream financial infrastructure.
Over the past year, stablecoin adoption has accelerated across payments, remittances, financial management, and international commerce. Companies ranging from fintech startups to multinational corporations have begun experimenting with blockchain-based payments as an alternative to traditional banking rails.
That momentum is attracting some of the world’s biggest financial and technology companies.
Last December, Stripe expanded globally $USDC Pay with Polygon enables merchants in over 150 countries to settle transactions using stablecoins. Earlier this year, Polygon also moved deeper into payments infrastructure through acquisitions aimed at enhancing fiat currency adoption, wallet services, and enterprise payments capabilities.
Polygon processed approximately $79 billion in stablecoin volume in May alone, ending the month with a record $3.7 billion in stablecoin supply circulating across its network.
The growth of the network reflects that trend.
Why throughput matters
The headline number of 5,000 transactions per second is only part of the story.
For companies evaluating blockchain payments, a bigger concern is often predictability.
Traditional payment networks can be expensive, but treasury departments usually know how much a transaction costs. In contrast, many blockchain networks can experience sudden spikes in fees during periods of high activity.
This unpredictability makes budgeting difficult for businesses that process large volumes of payments.
Polygon says its latest upgrades directly address this challenge by significantly increasing throughput without causing fluctuations in fees due to increased transaction demand.
This upgrade increases the network’s block gas limit to 160 million while maintaining a block time of 1.5 seconds, creating additional capacity for paying workloads.
As AI agents enter the payments ecosystem, their capabilities are likely to become increasingly important.
Autonomous systems are expected to generate large volumes of microtransactions, data purchases, access to APIs, and machine-to-machine payments execution at a scale that traditional financial infrastructure was not designed to handle.
Open Money Stack Vision
The throughput upgrade is part of Polygon’s broader effort to position Open Money Stack as a complete stablecoin infrastructure platform.
Rather than offering blockchain payments alone, this stack combines multiple components that businesses would typically have to assemble separately, including:
The goal is to reduce the complexity of deploying stablecoin payment systems at scale.
Businesses can access payments infrastructure through a single framework instead of having to coordinate or integrate multiple vendors.
For Polygon, the long-term opportunity extends beyond cryptocurrency users.
The company is increasingly targeting fintech companies, payment providers, enterprises, and ultimately AI-powered financial applications that require programmable movement of funds across global markets.
Race to become the payment layer of the Internet
Competition in blockchain-based payments is intensifying.
The circle continues to expand $USDC Recruitment across multiple chains. Stripe is integrating stablecoin payments into its global commerce platform. Traditional financial institutions are considering tokenized deposits and blockchain payment systems.
Meanwhile, networks like Solana, Ethereum, Base, and Avalanche are vying to become the infrastructure layer behind the next generation of internet-native payments.
Polygon believes that scalability, predictable fees, and integrated financial infrastructure will become more important than raw transaction counts alone.
As stablecoins increasingly move from crypto transactions to real-world commerce, networks that can support enterprise-grade payment flows are likely to become some of the most important financial infrastructure providers over the next decade.
For Polygon, the latest upgrade is designed to show that stablecoin payments are no longer an experiment.
They are becoming production systems.
