Stripe partners with Paradigm to launch Tempo, targeting global payments
Does Tempo represent a new opportunity, or does it conceal the recurrence of old challenges?
Navigating Web3 tides with focused insightsOn September 4, payments giant Stripe announced it is teaming up with top crypto venture capital firm Paradigm to launch a new public blockchain called Tempo. Positioned as a payment-focused, EVM-compatible Layer1, Tempo aims to achieve over 100,000 transactions per second and sub-second finality, targeting real-world use cases such as cross-border payments. The announcement quickly attracted market attention—supporters believe Stripe's entry could drive mass adoption of on-chain payments and usher in a new phase for stablecoins within global financial infrastructure, while skeptics argue that Tempo is essentially a consortium chain built by a payments giant for commercial interests. Does Tempo represent a new opportunity, or does it risk repeating old pitfalls? This article from CoinW Research explores the question.
1. Tempo’s Positioning and Vision
1.1 Tempo is a Payment-Focused Layer1
Tempo argues that although existing blockchains have made breakthroughs in smart contracts and application ecosystems, they still face three major bottlenecks in payments: volatile transaction fees, unpredictable settlement delays, and lack of scalable modules. For applications like cross-border clearing, these issues directly limit widespread adoption. Tempo's approach is to concentrate resources on this vertical domain—payments—prioritizing stability and efficiency as a dedicated Layer1. At the same time, leveraging Stripe’s merchant network and payment interface advantages, Tempo seeks to fill the current gap in public blockchains’ payment infrastructure.
This positioning also challenges the existing structure of the payments industry. In traditional systems, clearing networks like Visa have long controlled transaction pathways and fee structures, leaving merchants and users to passively accept established rules. Tempo attempts to move this model on-chain but operate it through protocols. Through designs such as “stablecoin-as-Gas” and built-in payment routing, on-chain payments become closer to real-world scenarios, ensuring predictability and certainty. Tempo does not aim to recreate a general-purpose public chain ecosystem; instead, its core goal is stability and efficiency, serving as an intermediary layer between real-world payment systems and the blockchain world. If this vision materializes, Stripe could evolve beyond being just a traditional payment gateway into a rule-setter for settlements, securing a strategic position in on-chain financial infrastructure.

1.2 Core Technical Features of Tempo
Tempo emphasizes payment-first design, with technical features centered around stability, compliance, and efficiency. It allows users to pay transaction fees using any stablecoin; dedicated payment channels ensure transactions are unaffected by other on-chain activities, maintaining low cost and high reliability; additionally, Tempo natively supports low-fee swaps between different stablecoins—including enterprise-issued custom stablecoins—further enhancing network compatibility. Furthermore, batch transfers enabled by account abstraction allow multiple transactions to be processed at once, significantly improving capital operation efficiency; a whitelist/blacklist mechanism meets regulatory requirements for user permission management at the base layer, providing necessary compliance safeguards for institutional participation. Finally, the transaction memo field is compatible with the ISO 20022 standard (developed by the International Organization for Standardization to unify financial messaging across payments, clearing, and securities), enabling smoother reconciliation between on-chain and off-chain processes.
These characteristics define Tempo’s application scope around payments and fund settlement. In global payments, Tempo can directly handle high-frequency operations like cross-border collections; embedded financial accounts enable enterprises and developers to manage funds efficiently on-chain; fast, low-cost remittance functions could reduce intermediary costs in cross-border transfers, increasing inclusivity. Looking further ahead, Tempo may support real-time clearing of tokenized deposits, enabling 24/7 financial services; in micro-payments and agent-based automated payments, its low cost and automation advantages could help expand emerging applications.
Thus, one key distinction between Tempo and other mainstream stablecoin chains like Plasma becomes apparent—its "openness." Tempo allows anyone to issue stablecoins and supports any stablecoin as gas for transaction fees; Plasma offers zero-fee USDT transfers, customizable Gas tokens, and privacy features, prioritizing payment performance and user experience; Circle Arc sets USDC as native on-chain Gas, making USDC and USYC core assets of the ecosystem, deeply integrated with Circle’s payment network and wallets. Overall, Plasma emphasizes payment performance, Arc focuses on compliant vertical integration, while Tempo builds a more diverse stablecoin foundation.
1.3 Tempo is Still in Testnet Phase
It should be noted that Tempo remains in testnet phase. According to public information, current operations are limited to small-scale validation environments focused on testing basic use cases like cross-border payments. Officially claimed performance metrics—such as 100,000 TPS, sub-second confirmation, and stablecoin-as-Gas—are currently only verified under controlled conditions.
Tempo has already onboarded several partners from the payments, banking, and tech industries, including Visa, Deutsche Bank, Shopify, Nubank, Revolut, OpenAI, and Anthropic. Tempo states it will first pilot with a select group of enterprise users and developers, ensuring benchmarks in security, compliance, and user experience are met before opening broader public testing and mainnet deployment.
2. Key Market Controversies Around Tempo
2.1 Why Didn’t Tempo Choose an Ethereum Layer2?
Instead of building as an Ethereum Layer2, Tempo chose to create a new Layer1—a decision sparking community debate. Given that Paradigm has long been seen as a staunch supporter of the Ethereum ecosystem, this move surprised many core members and raised skepticism. Matt, co-founder of Paradigm and leader of Tempo, cited two main reasons. First, existing Layer2 solutions are too centralized. Even leading Layer2s like Base rely on single-node sequencer architectures, meaning if the node fails, the entire network could halt. Since Tempo aims to serve as a global payment network involving thousands of partner institutions, relying on a single point of control would make it difficult to establish sufficient trust among participants. Tempo believes 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 finality of Layer2 depends on Ethereum’s mainnet, requiring periodic bundling and confirmation of transactions back on-chain. For regular users, this means deposit and withdrawal actions on Layer2 often involve longer wait times. While acceptable for small transactions, such delays extend settlement cycles in global payment systems, undermining the advantage of stablecoins as instant clearing tools. By contrast, Tempo’s architecture targets sub-second finality and meets the efficiency demands of payment systems. Therefore, building a standalone Layer1 is essential for creating a foundational network capable of handling large-scale payment settlements.

2.2 Questions About Tempo’s Neutrality
Tempo claims it will remain neutral, allowing anyone to issue and use stablecoins on-chain. However, some argue this claim contains logical flaws. First, Tempo is not fully open during its launch phase—it operates via a set of permissioned validators. This contradicts its stated principle of “anyone can freely participate.” Meanwhile, although Tempo allows users to pay or transfer using various stablecoins, operational control remains in the hands of a few major institutions. If a high-risk entity attempts to issue a stablecoin on Tempo in the future, validators like Visa—a licensed financial institution—is unlikely to process such transactions, rendering true neutrality impossible.
Another concern is that historically, almost no network starting as permissioned has successfully transitioned to a fully decentralized, open system. When companies hold operational power at launch, they also control revenue distribution. From a business standpoint, there is little incentive for institutions like Visa to voluntarily relinquish this power—especially not to potential future competitors. For this reason, Tempo’s “neutrality” appears more as a market narrative than a realistic possibility. Looking at past large financial infrastructures—from Visa to clearinghouses—nearly all have trended toward greater centralization. For Tempo to break this historical pattern, it must overcome significant resistance.
2.3 Tempo Resembles a Consortium Chain
Structurally, Tempo is criticized for resembling a consortium chain. Currently, validator access is not open to all but dominated by partner organizations. While this ensures stability, it also concentrates governance power among a small group of institutions, failing to reflect the decentralization and permissionless nature emphasized in the crypto space. In essence, Tempo embeds a consortium logic from the start—one aligned with inter-enterprise clearing networks rather than open, public blockchains in the traditional sense.
Tempo’s value lies more in offering these institutions a compliant and controllable testing ground rather than technically surpassing existing public chains. However, this comes at the cost of limited openness and neutrality. Even though it maintains EVM compatibility and technical links to the Ethereum ecosystem, overall, it functions more like an institution-led consortium chain than a genuine public infrastructure.
3. Strategic Significance of Tempo
3.1 Stripe’s Crypto Strategy
Tempo’s emergence is not isolated but a natural extension of Stripe’s long-term strategy in crypto. From early cautious exploration, to betting on stablecoins, and now building a payment-first public chain, Stripe’s strategic trajectory has become increasingly clear. Key milestones in its crypto journey include:
- January 2018: Announced discontinuation of Bitcoin payment support due to slow transaction speeds and low user interest, ending a four-year crypto experiment.
- October 2024: Restarted crypto payments in the U.S., enabling merchants to receive USDC and USDP stablecoins with instant settlement into USD at rates below credit card fees.
- February 2025: Acquired Bridge, a stablecoin infrastructure company, for approximately $1.1 billion, emphasizing stablecoins as a key driver for cross-border commerce.
- May 2025: Launched stablecoin financial accounts available in 101 countries, supporting stablecoin deposits, withdrawals, and cross-chain payments, and partnered with Visa to launch a stablecoin spending card.
- June 2025: Announced acquisition of Privy, a Web3 wallet infrastructure company, further strengthening its crypto wallet and user account systems.
- September 2025: Officially launched Tempo as a payment-first Layer1.
3.2 Outlook for Tempo
Tempo’s launch represents not only a continuation of Stripe’s crypto initiatives but also a strategic leap. Unlike previous functional experiments, Tempo enters at the infrastructure level, aiming to reshape the underlying logic of cross-border payments and clearing. It embodies Stripe’s ambition to bring hundreds of millions of merchants and users into on-chain payments, leveraging enterprise-grade resources to push blockchain into the mainstream. From a macro perspective, Tempo launches at a relatively favorable moment. On one hand, stablecoin adoption in cross-border payments, savings, and clearing continues to grow; on the other, regulatory frameworks for stablecoins are gradually taking shape. In this context, Stripe’s global merchant network provides Tempo with ready-made transaction scenarios. Combined with participation from partners like Visa, Shopify, Deutsche Bank, and OpenAI, Tempo can build a “closed-loop testbed” covering acquiring, clearing, and application layers.
However, Tempo’s long-term prospects remain uncertain. Meta’s Libra project demonstrated that enterprise-led chains often struggle to balance decentralization and market consensus under regulatory pressure. In comparison, Tempo’s design aligns better with current regulatory expectations, but its consortium-style governance implies highly concentrated power and persistent path dependency. If it fails to gradually introduce more open participation mechanisms, Tempo may be perceived merely as an extension of Stripe’s commercial empire rather than a true public infrastructure. Overall, Tempo’s future hinges not only on balancing efficiency and openness but also on earning institutional trust within compliance frameworks and gradually building cross-network consensus. Only if these conditions are progressively met can Tempo transcend its role as a commercial trial and evolve toward becoming a genuinely public infrastructure, with its long-term value unfolding accordingly.
