Stripe teams up with Paradigm to launch Tempo, targeting global payments

Author: CoinW Research Institute

On September 4, the payments giant Stripe announced that it was partnering with Paradigm, a top-tier venture capital firm in the crypto space, to launch a new public chain called Tempo. Tempo is positioned as a payment-focused, EVM-compatible Layer1, with the goal of achieving throughput of more than 100,000 transactions per second and sub-second finality, targeting real-world use cases such as cross-border payments.

Tempo’s launch quickly drew market attention. Supporters believe that Stripe’s entry could drive mass adoption of payments on-chain, ushering in a new stage for stablecoins’ use in global financial infrastructure. Critics, however, argue that Tempo is essentially an alliance chain built by a payments giant for commercial interests. Does Tempo represent a new opportunity, or is it merely replaying the familiar dilemmas of the past? In this article, the CoinW Research Institute will explore this question.

1. Tempo’s Positioning and Vision

1.1 Tempo is a Layer1 focused on payments

Tempo believes that although existing blockchains have made breakthroughs in smart contracts and application ecosystems, they still face three major bottlenecks in the payments layer: transaction fees fluctuate, settlement latency is unpredictable, and there is a lack of scalable block capacity. For use cases such as cross-border clearing, these problems directly limit widespread adoption. Tempo’s entry point is to concentrate resources on this vertical payment domain—focusing on stability and efficiency—while remaining a Layer1 dedicated to payments. At the same time, leveraging Stripe’s merchant network and payment interface advantages, Tempo aims to fill the current gap in public chain payment infrastructure.

This positioning also challenges the existing landscape of the payments industry. In the traditional system, clearing networks like Visa have long controlled the transaction path and fee structure, leaving merchants and users with little choice but to passively accept existing rules. Tempo seeks to migrate this model to the chain, but to operate it in a protocolized way. Through designs such as “stablecoins as Gas” and built-in payment routing, on-chain payments become closer to real-world scenarios, while also ensuring transaction predictability and determinism. Tempo’s goal is not to recreate a general-purpose public chain ecosystem, but to become a middle layer between real payment systems and the blockchain world, with stability and efficiency at its core. If this vision can be realized, Stripe could potentially evolve further—from a traditional payment gateway to a rule-maker for settlement—occupying a strategic position in on-chain financial infrastructure.

1.2 Tempo’s Core Technical Features

Tempo’s design emphasizes payments-first, with its technical characteristics centered on stability, compliance, and efficiency. It allows users to pay transaction fees using any stablecoin. Dedicated payment channels ensure that transactions are not disturbed by other on-chain activities, thereby maintaining low costs and high reliability. Meanwhile, Tempo natively supports low-fee swaps across different stablecoins, and even includes stablecoins issued by enterprises with custom issuance, further enhancing network compatibility. In addition, batch transfer functionality is enabled through account abstraction for one-time processing of multiple transactions, greatly improving capital operation efficiency. The blacklist/whitelist mechanism also meets regulators’ requirements for user permission management at the underlying layer, providing the compliance assurance needed for institutions to participate. Finally, the design of the transaction memo field is compatible with the ISO 20022 standard (devised by the International Organization for Standardization, used to standardize cross-border financial communications such as payments, clearing, and securities), making on-chain transactions and off-chain reconciliation workflows smoother.

These features determine that Tempo’s application scenarios revolve around payments and capital settlement. In global payments, Tempo can directly handle high-frequency businesses such as cross-border receiving. Embedded financial accounts allow enterprises and developers to achieve efficient on-chain capital management. Fast, low-cost remittance features are expected to reduce intermediary costs for cross-border transfers, improving accessibility. Further, Tempo can also support real-time clearing of tokenized deposits, enabling financial services 24/7. In micro-payments and intelligent agent payment scenarios, the low-cost and automation advantages can help expand emerging applications.

From this, we can observe a key difference between Tempo and other mainstream stablecoin public chains such as Plasma: its “openness.” Tempo allows anyone to issue stablecoins and supports any stablecoin being used directly as payment fees. Plasma, by contrast, provides USDT transfers with zero fees, a customizable Gas token mechanism, privacy support, and more. It prioritizes payment performance and user experience. Circle Arc sets USDC as on-chain native Gas, and along with stablecoins such as USYC, it becomes a core ecosystem asset. It is also deeply integrated with Circle’s payment network and wallets. Overall, Plasma emphasizes payment performance, Arc locks in compliance-focused vertical integration, while Tempo builds a more diversified stablecoin underlying layer.

1.3 Tempo is still in the testnet stage

It is worth noting that Tempo is still in the testnet stage. According to public information, during this phase, operations mainly focus on small-scale validation environments to test foundational scenarios such as cross-border payments. Officially disclosed performance data—such as supporting 100,000 transactions per second, sub-second finality, and a stablecoin-as-Gas payment model—has, for now, only been verified in controlled environments.

So far, Tempo has introduced a set of partners from the payments, banking, and technology industries, including Visa, Deutsche Bank, Shopify, Nubank, Revolut, OpenAI, Anthropic, and others. Tempo says it will first pilot with a small number of enterprise users and developers. Only after meeting standards across safety, compliance, and user experience will it open up larger-scale public testing and mainnet deployment.

2. The Main Controversies Around Tempo in the Market

2.1 Why Tempo didn’t choose Ethereum Layer2

Tempo did not rely on Ethereum to build a Layer2, but instead chose to build an entirely new Layer1 from scratch, which has sparked heated discussion in the community. Because Paradigm has long been regarded as a steadfast supporter of the Ethereum ecosystem, this move surprised many core members and also led to community skepticism. Paradigm co-founder and Tempo leader Matt attributes this to two considerations. First, the existing Layer2s have an excessively high degree of centralization. Even leading Layer2s like Base still use a single-node sorter architecture; if a node goes down, the entire network could effectively stall. Tempo aims to become a global payments network involving thousands of partner institutions. If the underlying layer depends on single-point control, it will be difficult for institutions to build sufficient trust. Tempo believes that only a truly multi-node, decentralized validator network can support the neutrality and security required for cross-border payments.

Second, the reason is related to settlement efficiency. The finality of Layer2, in practice, depends on the Ethereum main chain. Transactions need to be periodically batched back to the main chain for confirmation. For ordinary users, this means deposits and withdrawals on Layer2 often require longer waiting times. In small-transaction scenarios, this latency may be tolerable, but for a global payments system, it extends the settlement cycle and weakens stablecoins’ advantage as an immediate-clearing tool. By contrast, Tempo pursues sub-second finality at the architectural level and meets the efficiency required for payments. Therefore, building a Layer1 from scratch is intended to create a truly foundational network capable of large-scale payment settlement.

2.2 Tempo’s neutrality is in question

Tempo officially claims it will remain neutral, and that anyone can issue and use stablecoins on-chain. But some people believe this claim has logical problems. First, in its launch phase, Tempo is not a fully open public chain; it is run by a set of permissioned validators. This contradicts its promoted “anyone can freely participate” stance. At the same time, although Tempo allows users to make payments or transfers using different stablecoins, the underlying operating power is still held by a small number of major institutions. If, in the future, a high-risk entity attempts to issue a stablecoin on Tempo, validators operated by licensed institutions such as Visa would be almost impossible to process such transactions—making neutrality effectively impossible to substantiate.

Another point of criticism is that skeptics believe that historically, almost no network with a “permission first, then decentralize later” model has truly transitioned into an open system. When enterprises control operating power during the launch phase, it also means they control the authority over revenue distribution. From a commercial logic standpoint, there is no reason for institutions like Visa to voluntarily hand over that power and interest—especially to future competitors. For this reason, Tempo’s “neutrality” is more of a market narrative than a realistic possibility. Looking at the history of major financial infrastructure—from Visa to clearing houses—nearly all of them continue to move toward more centralized control. If Tempo wants to break this historical pattern, it must face significant resistance.

2.3 Tempo is more like an alliance chain

Meanwhile, from a structural design perspective, Tempo has been criticized as being closer to an alliance chain. At present, validator access is not open to everyone; it is led by partners. This architecture ensures stability, but it also means governance power is concentrated in the hands of a small number of institutions, making it hard to reflect the decentralization and permissionless attributes emphasized by the crypto industry. It can also be understood as Tempo embedding alliance-style logic from the beginning, which fits more with a clearing network formed among enterprises than with a traditionally “open” blockchain.

Tempo’s value is more about providing these institutions with a compliance-friendly, controllable testing ground rather than surpassing existing public chains at the technical level. As a result, Tempo’s openness and neutrality are also constrained. Even if it remains EVM-compatible and has technical ties to the Ethereum ecosystem, overall it is still more like an alliance chain led by institutional coalitions than a truly public infrastructure.

3. The Strategic Significance of Tempo

3.1 Stripe’s Crypto Strategy

The launch of Tempo is not an isolated event, but rather a natural extension of Stripe’s long-term planning in the crypto space. From early cautious experiments, to betting on stablecoins, to directly building a payments-first public chain, Stripe’s strategic trajectory has gradually become clear. Key milestones in Stripe’s crypto roadmap are as follows:

· January 2018: Announced it would stop supporting Bitcoin payments due to slow transaction speeds and insufficient user interest, ending a 4-year foray into crypto.

· October 2024: Restarted crypto payments in the United States, supporting merchants to receive USDC and USDP stablecoins, with instant settlement into USD and fees lower than credit cards.

· February 2025: Acquired stablecoin infrastructure company Bridge for about $1.1 billion, emphasizing that stablecoins will become a core driving force for cross-border commerce.

· May 2025: Launched stablecoin financial accounts covering 101 countries, supporting stablecoin deposits/withdrawals and cross-chain payments, and partnered with Visa to launch a stablecoin spending card.

· June 2025: Announced the acquisition of Web3 wallet infrastructure company Privy, further improving crypto wallet and user account systems.

· September 2025: Tempo formally launched, positioned as a payments-first Layer1.

3.2 Tempo’s outlook

Tempo’s release is not only a continuation of Stripe’s crypto strategy, but also a major shift in its strategic focus. Different from earlier functional experiments, Tempo directly moves into the infrastructure layer, aiming to reshape the underlying logic of cross-border payments and clearing. It is not only meant to carry Stripe’s ambition to bring hundreds of millions of merchants and users into on-chain payments, but also to drive blockchain adoption into the mainstream through enterprise-level resources. From a macro perspective, Tempo’s launch is happening at a relatively favorable time. On one hand, stablecoins’ penetration in cross-border payments, value storage, and clearing continues to rise. On the other hand, stablecoin compliance frameworks are also gradually becoming clearer. Against this backdrop, Stripe’s global merchant network provides Tempo with natural transaction scenarios. Combined with partner involvement from Visa, Shopify, Deutsche Bank, OpenAI, and others, Tempo can build a “closed-loop” experimental environment covering acquiring, clearing, and applications.

However, Tempo’s long-term outlook remains highly uncertain. Meta’s Libra has already shown that enterprise-led chains often struggle to balance decentralization and market consensus under compliance pressure. By contrast, Tempo’s design is more aligned with the current regulatory environment in terms of compliance adaptation. But its alliance-based governance architecture also means power is highly concentrated, making it difficult to fully escape path dependency. If the future cannot gradually introduce more open participation mechanisms, Tempo may end up being seen as an extension of Stripe’s business map rather than a truly public infrastructure. Overall, Tempo’s future depends not only on balancing efficiency and openness, but also on whether—under a compliance framework—it can earn institutional trust and gradually accumulate consensus effects across networks. Only if these conditions can be realized step by step will Tempo have a chance to break beyond the limitations of a commercialized testing phase and evolve toward the direction of infrastructure with public attributes. Its long-term value will also become increasingly apparent in this process.
