Stablecoins have been promising faster, cheaper and more efficient payments for years.
The challenge has never been the concept. It was the infrastructure.
While blockchain networks can handle impressive transaction volumes under normal circumstances, many still suffer from unpredictable fees and performance bottlenecks when demand increases. For companies that process payroll, remittances, cross-border transfers or B2B payments, that uncertainty creates a problem that finance teams simply cannot accept.
Polygon believes it has solved it.
The company announced that Polygon Chain, the settlement layer powering the Open Money Stack, can now process up to 5,000 payment transactions per second following a network upgrade that significantly increases throughput while keeping costs low and predictable.
The milestone puts Polygon in the same performance conversation as the major global payment networks, while retaining the benefits that made stablecoins attractive in the first place: near-instant settlement, programmable transactions, and significantly lower fees.
The opportunity for Stablecoin continues 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 in the areas of payments, remittances, treasury management and international trade. Companies ranging from fintech startups to multinational corporations have begun experimenting with blockchain-based settlement as an alternative to traditional bank rails.
That momentum has attracted some of the world’s largest financial and technology companies.
Last December, Stripe expanded globally $USDC payments on Polygon, allowing merchants in more than 150 countries to settle transactions using stablecoins. Earlier this year, Polygon also delved deeper into payments infrastructure through acquisitions designed to strengthen fiat-on-ramps, wallet services and enterprise payments capabilities.
Polygon processed approximately $79 billion in stablecoin volumes in May alone and ended the month with a record $3.7 billion in stablecoin volume circulating across the network.
The growth of the network reflects that trend.
Why transit is important
The headline number – 5,000 transactions per second – is only part of the story.
For companies evaluating blockchain payments, the biggest concern is often predictability.
Traditional payment networks can be expensive, but finance departments generally know what transactions will cost. In contrast, many blockchain networks can experience sudden rate spikes during periods of heavy activity.
That unpredictability makes budgeting difficult for companies that process large payment volumes.
Polygon says the latest upgrade directly addresses these challenges by enabling significantly higher throughput without introducing cost volatility as transaction demand increases.
The upgrade increases the network’s block gas limit to 160 million while maintaining 1.5 second block times, creating additional capacity for heavy workloads.
That capability could become increasingly important as AI agents enter the payments ecosystem.
Autonomous systems are expected to generate large volumes of microtransactions, purchase data, access APIs, and make machine-to-machine payments at a scale that traditional financial infrastructure was never designed for.
The Open Money Stack Vision
The throughput upgrade is part of Polygon’s broader efforts to position the Open Money Stack as a complete stablecoin infrastructure platform.
Rather than just offering blockchain settlement, the stack combines multiple components that businesses typically have to put together separately, including:
The goal is to reduce the complexity of deploying stablecoin payment systems at scale.
Instead of coordinating multiple vendors and integrations, businesses can access payment infrastructure through a single framework.
For Polygon, the long-term opportunities extend beyond just crypto users.
The company is increasingly focused on fintech companies, payment providers, enterprises and ultimately AI-powered financial applications that require programmable money movements across global markets.
A race to become the payment layer of the internet
Competition in blockchain-based payments is becoming increasingly fierce.
Circle continues to expand $USDC adoption in multiple chains. Stripe integrates stablecoin payments into its global trading platform. Traditional financial institutions are exploring tokenized deposits and blockchain settlement systems.
Meanwhile, networks such as Solana, Ethereum, Base, Avalanche and others are competing to become the infrastructure layer behind the next generation of internet-native payments.
Polygon’s bet is that scalability, predictable fees and integrated financial infrastructure will be more important than just the number of transactions.
As stablecoins increasingly transition from crypto trading to real-world trading, the networks that can support enterprise-level payment flows could become one of the most important financial infrastructure providers of the coming decade.
For Polygon, the latest upgrade is designed to show that stablecoin payments are no longer an experiment.
They become a production system.
