Why Every Major Payments Network is Building Its Own Chain

Stripe built Tempo. Circle built Arc. Tether is backing Plasma. PayPal issued PYUSD. JPMorgan's Kinexys is settling $2 billion a day and expanding to Base. Visa has VTAP. Mastercard has its Multi-Token Network.

The largest players in the global payment stack have made the same move in rapid succession. That is not a trend. That is a structural shift in how financial infrastructure gets built.

The orthodoxy that broke

For the first ten years of crypto, the dominant view was that payments would eventually settle on general-purpose public blockchains. Ethereum, Avalanche, Solana, or whoever won the throughput race would become the settlement layer for global commerce. Payment companies would build on top, the same way software companies build on top of cloud infrastructure. The chain was the commodity. The application was where the value accrued.

That assumption has broken down, and the companies closest to actual enterprise money flows figured it out first.

The problem is not that public blockchains are bad. It is that they were not designed for payments. Running enterprise payment flows on a general-purpose public chain means inheriting a set of properties that are fundamentally incompatible with how institutions move money.

Transaction data is visible to everyone. Every settlement, every counterparty, every flow is readable by any competitor with a block explorer. For consumer applications, that is a minor nuisance. For an enterprise treasury team managing billions in interbank flows, it is a disqualifying condition.

Fees are unpredictable. Gas mechanics on public chains mean your cost structure fluctuates with network demand. What you model in a quarterly projection is not what you pay at settlement. At enterprise volume and margin, that unpredictability compounds quickly.

Finality is probabilistic. Most public chains offer transactions that are likely final and growing more certain over time. Enterprise treasury operations require deterministic finality. "Likely" is not a settlement guarantee a bank can build a product on.

Compliance is an afterthought. Public chains were architected for permissionless participation. Audit trails, KYC integration, and regulatory reporting were never native to the protocol. They get bolted on at the application layer, which means they are fragile and inconsistent across deployments.

The response: build your own

The industry's largest players have responded in a consistent way. Stop adapting to infrastructure that was not built for you. Build infrastructure that was.

In September 2025, Stripe launched Tempo, a purpose-built payment blockchain developed in partnership with Paradigm, the crypto-native investment firm that put in $500 million at a $5 billion valuation. Tempo is engineered for the use case Stripe knows better than anyone: high-volume, low-cost transaction settlement at scale. The chain is reported to target 100,000+ transactions per second, sub-second finality, and fees around $0.001 per transaction, economics built from the ground up for payments, not adapted from a general-purpose chain. Reported design partners include OpenAI, Shopify, Visa, and Deutsche Bank.

Circle moved earlier. The company announced Arc in August 2025 and opened its public testnet in October. Arc is Circle's own payment-native Layer 1, with USDC as the native gas token and a novel consensus mechanism called Malachite designed around a simple guarantee: transactions are either 100% final or unconfirmed. No probabilistic window. Arc includes opt-in privacy by default and is EVM-compatible, meaning it inherits the developer ecosystem without inheriting the settlement tradeoffs of Ethereum mainnet.

Tether launched Plasma on September 25, 2025. The chain is EVM-compatible, Tether-backed, and built on PlasmaBFT consensus. It launched with a reported $5.6 billion in TVL and $373 million raised, with Founders Fund among the disclosed backers. The pitch is direct: USDT-native settlement at near-zero cost, with zero-fee transfers for the stablecoin that holds roughly 60% of total market supply.

These are not experiments or side projects. They are strategic infrastructure investments from organizations that collectively move hundreds of billions in stablecoin volume. According to industry data, the stablecoin market reached approximately $306 billion in late 2025, up roughly 49% year over year, and crossed $1 trillion in monthly onchain volume for the first time in September 2025. These companies are building chains because every alternative was a compromise.

What all three are optimizing for

Look across Tempo, Arc, and Plasma and the shared design priorities become clear. Each is building toward the same four properties.

Privacy. Transaction data should not be visible to counterparties, competitors, or the public. For enterprise payments, confidentiality is not a feature request, it is a baseline requirement that no general-purpose public chain can reliably provide.

Deterministic finality. Sub-second settlement that is final, not probable. Enterprise treasury operations and institutional payment flows cannot be built on probabilistic guarantees. The settlement either happened or it did not.

Predictable fees. The ability to model payment economics at scale without variable gas mechanics creating cost uncertainty. For a company processing millions of transactions, even minor fee volatility compounds into a significant modeling problem.

Compliance by design. Audit trails, permissioning, and regulatory reporting built into the protocol layer, not patched in afterward. When compliance is native, it is consistent. When it is bolted on, it is a liability.

These are precisely the four properties that general-purpose public chains cannot deliver on enterprise terms. And they are the four properties that every major payment network is now building toward in its own infrastructure.

The regulatory floor arrives

This is not happening in a vacuum. On December 12, 2025, the OCC issued conditional national trust bank charters to BitGo, Fidelity Digital Assets, Paxos, Ripple, and First National Digital Currency Bank. The regulatory framework that enterprise payments requires is arriving at the same time as the infrastructure layer is being built.

JPMorgan has stated that Kinexys has processed over $1.5 trillion in notional value since 2020 and is now settling approximately $2 billion in daily transactions. It is expanding to Base, the public chain built by Coinbase. Traditional financial institutions are not watching this from the outside. They are making the same infrastructure bet from the other direction.

The window is open. The question is who builds through it.

What this means - and what it means for you

The pattern here is not subtle. Every institution at the center of the global payment stack has reached the same conclusion: shared infrastructure cannot support payment flows that require confidentiality, deterministic settlement, predictable economics, and compliance by design. The only way to get all four is to build the layer you operate on.

That conclusion raises an obvious question. Stripe had Paradigm and $500 million. Circle has been building blockchain infrastructure since 2013. Tether had Founders Fund and $373 million. What path does everyone else take?

That path exists. AvaCloud's managed Avalanche L1s give enterprises dedicated payment chains with the same four properties those companies spent hundreds of millions to engineer from scratch. Privacy at the protocol level, not applied after the fact. Sub-second finality that is deterministic, not probabilistic (in internal load testing, AvaCloud L1s have sustained over 1,700 TPS with average block finality of 0.5 seconds). Fee structures your organization sets rather than gas mechanics inherited from a network designed for something else. Compliance tooling that is native to the chain, not patched in at the application layer.

The window is still open. The stablecoin market hit $306 billion in November 2025. The OCC issued its first conditional digital asset bank charters in December. Monthly onchain volume crossed $1 trillion for the first time in September. The regulatory clarity and the infrastructure tooling are arriving at the same moment, which means the institutions that move now are the ones that define what the next decade of payment infrastructure looks like.

Most enterprises that need dedicated payment chain infrastructure are not Stripe. They should not have to spend 18 months and nine figures to get there.
