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

Author: CoinW Research Institute

On September 4th, payment giant Stripe announced a partnership with top crypto venture capital firm Paradigm to launch a new public blockchain called Tempo. Tempo is positioned as a payment-centric, EVM-compatible Layer 1, aiming to achieve a throughput of over 100,000 transactions per second and sub-second confirmations, targeting real-world applications such as cross-border payments.

The launch of Tempo quickly attracted market attention, with supporters believing that Stripe’s entry could drive large-scale on-chain payments and open a new phase for stablecoins in global financial infrastructure; skeptics argue that Tempo is essentially an alliance chain created by the payment giant for commercial interests. Does Tempo represent new opportunities, or does it hide the potential for a repeat of old dilemmas? In this article, CoinW Research Institute will explore this.

1. Positioning and Vision of Tempo

1.1 Tempo is a Layer 1 focused on payments

Tempo believes that while existing blockchains have made breakthroughs in smart contracts and application ecosystems, there are still three major bottlenecks in the payment process: high volatility in transaction fees, unpredictable settlement delays, and a lack of scalable modules. For cross-border clearing and other scenarios, these issues directly limit widespread adoption. Tempo’s entry point is to concentrate resources in the vertical field of payments, emphasizing stability and efficiency, and focusing on being a payment-centric Layer 1. At the same time, leveraging Stripe’s merchant network and payment interface advantages, Tempo aims to fill the current gap in public blockchain payment infrastructure.

This positioning also challenges the existing landscape of the payment industry. In the traditional system, clearing networks like Visa have long controlled transaction paths and fee structures, leaving merchants and users to passively accept existing rules. Tempo tries to migrate this model on-chain, but operates in a protocolized manner. Through designs like “stablecoin as Gas” and built-in payment routing, it makes on-chain payments closer to real-world scenarios while ensuring the predictability and certainty of transactions. Tempo’s goal is not to recreate a general-purpose public blockchain ecosystem, but to become an intermediary 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 from a traditional payment gateway into a rule-maker for settlement, occupying a strategic position in on-chain financial infrastructure.

1.2 Core technology characteristics of Tempo

Tempo emphasizes payment prioritization in its design, with technical features centered around stability, compliance, and efficiency. It allows users to pay transaction fees with any stablecoin; dedicated payment channels ensure that transactions are unaffected by other on-chain activities, maintaining low costs and high reliability; at the same time, Tempo natively supports low-fee swaps of different stablecoins, including enterprise-custom-issued stablecoins, further enhancing network compatibility. Additionally, the batch transfer feature, implemented through account abstraction, allows for one-time processing of multiple transactions, significantly improving capital operation efficiency; while the whitelist and blacklist mechanism satisfies regulatory requirements for user permission management at the foundational level, providing necessary compliance assurance for institutional participation. Finally, the design of the transaction memo field is compatible with the ISO 20022 standard (developed by the International Organization for Standardization for standardizing cross-border financial communications such as payments, clearing, and securities), making on-chain transactions and off-chain reconciliation processes smoother.

These characteristics determine that Tempo’s application scenarios revolve around payments and fund settlements. In global payments, Tempo can directly support high-frequency businesses like cross-border receipts; embedded financial accounts enable businesses and developers to achieve efficient fund management on-chain; the rapid low-cost remittance feature is expected to reduce intermediary costs for cross-border transfers, enhancing inclusivity. Furthermore, Tempo can also support real-time settlement of tokenized deposits, bringing around-the-clock financial services; in scenarios involving micropayments and smart agent payments, the advantages of low cost and automation can help expand emerging applications.

As a result, a major distinction between Tempo and other mainstream stablecoin public blockchains like Plasma is its “openness.” Tempo allows anyone to issue stablecoins and supports any stablecoin to be used directly as transaction fees; Plasma, on the other hand, provides zero-fee USDT transfers, customizable Gas token mechanisms, confidentiality support, and prioritizes payment efficiency and experience; Circle Arc sets USDC as the native Gas on-chain and integrates it deeply with USYC and other stablecoins as core ecosystem assets alongside Circle’s payment network and wallet. Overall, Plasma emphasizes payment performance, Arc focuses on compliant vertical integration, while Tempo creates a more diversified stablecoin foundation.

1.3 Tempo is still in the testnet phase

It is important to note that Tempo is still in the testnet phase. According to public information, this phase primarily focuses on a small-scale verification environment, testing foundational scenarios such as cross-border payments. The performance data released by the official, such as supporting 100,000 transactions per second, sub-second confirmations, and the stablecoin-as-Gas payment model, is currently only verified in a controlled environment.

Currently, Tempo has introduced a group of partners from the payment, banking, and technology sectors, including Visa, Deutsche Bank, Shopify, Nubank, Revolut, OpenAI, and Anthropic. Tempo states that it will first pilot among a small number of enterprise users and developers, ensuring that safety, compliance, and user experience standards are met before opening up larger-scale public testing and mainnet deployment.

2. Main controversies regarding Tempo in the market

2.1 Why did Tempo choose not to build on Ethereum Layer 2

Tempo did not rely on Ethereum to build a Layer 2, but instead chose to create an entirely new Layer 1, which has sparked heated discussions in the community. Given that Paradigm has long been seen as a staunch supporter of the Ethereum ecosystem, this move surprised many core members and raised questions in the community. Paradigm co-founder and Tempo leader Matt attributed this to two considerations: first, the existing Layer 2s are too centralized. Even leading Layer 2s like Base still adopt a single-node ordering architecture; if the node encounters issues, the entire network could halt. Tempo’s goal is to become a global payment network involving thousands of partner institutions, and if the underlying system relies on single-point control, it’s difficult to establish sufficient trust among institutions. Tempo believes that only a truly multi-node, decentralized validator network can provide the neutrality and security required for cross-border payments.

The second reason relates to settlement efficiency; the final certainty of Layer 2 actually depends on the Ethereum main chain, requiring periodic packaging of transactions back to the main chain for confirmation. For ordinary users, this means that deposit and withdrawal operations on Layer 2 often require longer waiting times. In low-value transaction scenarios, this delay may be acceptable, but for a global payment system, it extends the settlement cycle and undermines the advantage of stablecoins as instant settlement tools. In contrast, Tempo pursues sub-second finality in its architecture and meets the efficiency required for payments. Thus, building its own Layer 1 is aimed at creating a foundational network that truly meets the needs of large-scale payment settlements.

2.2 Doubts about Tempo’s neutrality

Tempo officially claims to maintain neutrality, allowing anyone to issue and use stablecoins on-chain. However, some believe this statement has logical flaws. First, at its launch stage, Tempo is not a completely open public chain, but rather run by a group of permissioned validators. This contradicts its promotion of “anyone can freely participate.” Meanwhile, while Tempo allows users to pay or transfer using different stablecoins, the underlying operational power still rests with a few large institutions. If high-risk entities attempt to issue stablecoins on Tempo in the future, it would be nearly impossible for validators like Visa to handle these transactions, making neutrality a moot point.

Another point of contention is that skeptics argue that historically, there has been almost no “permissioned, then decentralized” network that has successfully transitioned to an open system. When enterprises hold operational power at the initiation stage, it means they also control the power of profit distribution. From a business logic perspective, institutions like Visa have no reason to voluntarily relinquish this power and interest, especially to potential future competitors. Therefore, Tempo’s “neutrality” appears more as a market narrative rather than a realistic possibility. In contrast, all major financial infrastructures, from Visa to clearinghouses, have almost always moved toward more centralized control. For Tempo to break this historical pattern, it must face significant resistance.

2.3 Tempo leans more towards being an alliance chain

At the same time, from the structural design perspective, Tempo is criticized for being closer to an alliance chain. Currently, its validator access is not open to everyone, but led by partners. This architecture ensures stability but also means governance power is concentrated in the hands of a few institutions, making it difficult to reflect the decentralization and permissionless attributes emphasized in the crypto industry. It can also be understood that Tempo inherently integrates an alliance-like logic from the outset, aligning more with the model of establishing clearing networks among enterprises rather than a traditional open blockchain.

Tempo’s value lies more in providing these institutions with a compliant and controllable testing ground rather than surpassing existing public chains on a technical level, but this also limits Tempo’s openness and neutrality. Even though it maintains EVM compatibility and has technical ties to the Ethereum ecosystem, from an overall logic standpoint, it resembles an alliance chain led by institutional coalitions rather than a truly public infrastructure.

3. Strategic significance of Tempo

3.1 Stripe’s crypto layout

The birth of Tempo is not an isolated event but a natural extension of Stripe’s years of planning in the crypto field. From early cautious exploration to betting on stablecoins, and now creating a payment-focused public chain, Stripe’s strategic trajectory is becoming clearer, with key nodes in its crypto layout as follows:

· January 2018: Announced the cessation of Bitcoin payment support, citing slow transaction speeds and insufficient user interest, ending a four-year attempt in crypto.

· October 2024: Restarted crypto payments in the U.S., allowing merchants to accept USDC and USDP stablecoins, and converting them to USD instantly at lower rates than credit cards.

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

· May 2025: Launched stablecoin financial accounts covering 101 countries, supporting stablecoin deposits and cross-chain payments, and partnered with Visa to launch stablecoin debit cards.

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

· September 2025: Tempo officially launched, positioned as a payment-focused Layer 1.

3.2 Prospects of Tempo

The launch of Tempo is not only a continuation of Stripe’s crypto layout but also a leap in its strategic focus. Unlike previous functional attempts, Tempo directly addresses the infrastructure layer, aiming to reshape the underlying logic of cross-border payments and settlements. It not only embodies Stripe’s ambition to bring hundreds of millions of merchants and users into on-chain payments but also leverages enterprise-level resources to propel blockchain into the mainstream. From a macro perspective, the launch of Tempo occurs at a relatively favorable time. On one hand, the penetration of stablecoins in cross-border payments, storage, and settlements is continually increasing; on the other hand, the regulatory framework for stablecoins is gradually clarifying. Against this backdrop, Stripe’s global merchant network provides Tempo with natural transaction scenarios, coupled with participation from partners like Visa, Shopify, Deutsche Bank, and OpenAI, allowing Tempo to build a “closed-loop testing ground” covering acquiring, clearing, and applications.

However, Tempo’s long-term prospects still face significant uncertainties. Meta’s Libra has already shown that enterprise-led chains often struggle to balance decentralization and market consensus under regulatory pressure. In contrast, Tempo’s design is more aligned with the current regulatory environment, but its alliance governance structure also means power is highly centralized, making it difficult to completely escape path dependence. If it cannot gradually introduce more open participation mechanisms in the future, Tempo may be viewed as an extension of Stripe’s commercial landscape rather than a truly public infrastructure. Overall, Tempo’s future depends not only on balancing efficiency and openness but also on whether it can gain institutional trust within a compliance framework and gradually accumulate cross-network consensus effects. If these conditions can be gradually met, Tempo may have the opportunity to break through the limitations of commercial experimentation and develop towards a public infrastructure, and its long-term value will gradually manifest in this process.
