Introduction​

Stripe's Tempo is a newly launched Layer-1 (L1) blockchain network with a core focus on processing high-speed, low-cost stablecoin payments. The project was co-incubated by payments giant Stripe and prominent crypto venture capital firm Paradigm. From its inception, it has been positioned as a "payments-first" blockchain, designed to meet the demanding scale and performance requirements of real-world financial scenarios. In 2025, Tempo entered a private testnet phase, co-designing and validating its features with several heavyweight partners, including Visa, Deutsche Bank, Shopify, and OpenAI. For the developer community, the emergence of Tempo presents a new opportunity—to build the next generation of payment applications on an underlying infrastructure optimized for stablecoins and commerce use cases. This guide will detail how developers can technically integrate with Tempo, what resources and communities are available, and how to participate in this growing ecosystem.

1. Technical Integration: Building on L1 Tempo​

A core design philosophy of Tempo is to lower the barrier to entry for developers by choosing a path of full Ethereum compatibility. This means developers can build on it using existing mature tools and knowledge bases. Tempo's architecture is based on Reth (a Rust implementation of an Ethereum client led by Paradigm), making it naturally compatible with Ethereum smart contracts and its developer toolchain.

Here are its key technical features and integration points:

• EVM and Smart Contracts: Tempo fully supports Solidity smart contracts and the Ethereum Virtual Machine (EVM). Developers can use standard frameworks like Hardhat, Truffle, and Foundry, as well as libraries like ethers.js and web3.js, to write, test, and deploy smart contracts. For Web3 developers, this seamless compatibility means there is almost no learning curve. Existing dApps, wallets (like MetaMask), and development tools work "out-of-the-box" on Tempo, paving the way for the easy migration of mature applications from Ethereum.

• High Throughput & Finality: Tempo has been deeply optimized for the speed requirements of payment scenarios. Its design target is to achieve a processing capacity of over 100,000 transactions per second (TPS) and to reach sub-second deterministic finality. This means that once a transaction is confirmed, it is irreversible, eliminating the risk of transaction reordering (reorgs) that can occur with traditional probabilistic confirmations (like Proof-of-Work). This high performance and certainty are crucial for applications with stringent instant settlement requirements, such as point-of-sale (POS) systems, exchanges, and micropayments.

• Stablecoin-Native Design: Unlike most general-purpose public chains, the Tempo network does not rely on a volatile native token to pay for transaction fees (Gas). Transaction fees on its network can be paid directly using major stablecoins (like USDC, USDT, etc.). To achieve this, the protocol integrates an automated market maker (AMM) that can automatically handle swaps between different stablecoins in the background, ensuring "issuer neutrality" for fee payments. For developers and users, this greatly improves the experience, as transaction costs can be stably pegged to fiat value (e.g., always around $0.001), avoiding the uncertainty caused by native token price volatility.

• Payment-Oriented Features: Tempo adds several features at the protocol level tailored for financial and payment applications. These include:

  • "Payment Lanes": By isolating payment-type transactions from other types of on-chain activity (like complex DeFi operations), these lanes ensure low latency and high priority for payments.
  • Native Batch Transfers: Leveraging technologies like Account Abstraction, it supports efficiently sending payments to multiple addresses in a single transaction, which is highly practical for scenarios like payroll and supplier payments.
  • Transaction Memo Fields: This field is compatible with the ISO 20022 financial messaging standard, allowing metadata such as invoice reference numbers or compliance data to be attached to on-chain transactions, greatly simplifying corporate financial reconciliation processes.
  • Optional Privacy: The protocol supports optional transaction privacy features to meet enterprise compliance needs for protecting commercially sensitive information.

• Integration via Stripe API: Stripe plans to deeply integrate Tempo into its existing product suite, offering developers two integration paths. The first is direct on-chain development, where Web3 developers use familiar toolchains to deploy smart contracts directly on Tempo. The second is integration via Stripe's high-level APIs, which completely abstracts away the complexity of the blockchain. For example, Stripe's Bridge platform (a tool for cross-chain stablecoin flows) will use Tempo as one of its core settlement rails in the future. Developers will only need to call Stripe's familiar REST API to initiate a payment or transfer, and the Stripe system will automatically execute it on the Tempo network in the background. This allows them to enjoy the speed and cost advantages of the blockchain without needing to worry about underlying details like node management or private key signing.

2. Developer Documentation, Tutorials, and Onboarding Resources​

As of late 2025, Tempo is still in a private testnet phase, and its official developer documentation is actively being written. However, Tempo's official website has confirmed that "comprehensive technical documentation for developers is coming soon."

In the meantime, interested developers can obtain preliminary information through the following channels:

• Official Website & FAQ: Visiting Tempo's official website and its Frequently Asked Questions (FAQ) page provides a high-level overview of its design philosophy, core features, and how it differs from general-purpose blockchains.
• Apply for Testnet Access: Interested developers or companies can submit an application through the channel provided on the Tempo website (partners@tempo.xyz) to gain access to its private testnet for early exploration and prototyping.

Based on Stripe's consistent focus on developer experience, we can expect the official documentation, once released, to include the following resources:

• Getting Started Guides: Detailed tutorials guiding developers on how to set up their development environment, connect to the Tempo testnet, and deploy their first smart contract.
• API References and SDK Documentation: Complete technical references for the Stripe API integration path, as well as documentation for the JSON-RPC endpoints for interacting with the Tempo protocol.
• Tutorials & Sample Applications: Open-source sample code and projects demonstrating how to build common payment applications on Tempo.
• Best Practices: Professional advice on security, compliance, performance optimization, and other areas.

Stripe is renowned for its clear, high-quality API documentation, and there is good reason to believe that Tempo's documentation will maintain the same standard.

3. Stripe’s Developer Engagement Channels and Community​

Stripe has a mature and active developer community ecosystem. For developers who want to stay updated on Tempo and receive technical support, the following official channels are available:

• Stripe Developer Discord: This is a large community with over 120,000 members, where Stripe engineers directly participate in answering questions. The latest announcements, technical discussions, and community support for Tempo can all be found here.
• Online Forums and Q&A Platforms: Stripe's team actively monitors and responds to questions posted on Stack Overflow (using the stripe tag) and Twitter/X (@StripeDev).
• Stripe Blog and Newsletters: This is the primary channel for official information, in-depth technical articles, and product updates. Major milestones and case studies for Tempo will be published here.
• Developer Events & Webinars: Stripe regularly hosts online and offline events. In particular, its annual developer conference, Stripe Sessions, is often the platform for major product announcements and will likely feature dedicated technical sessions and workshops for Tempo in the future.

By tapping into these established channels, developers can easily obtain information, solve problems, and connect with other developers interested in Tempo.

4. Opportunities to Contribute to the Tempo Ecosystem​

As Tempo transitions from an internal incubation project to an open public network, developers have various ways to participate and contribute to its ecosystem beyond just building applications:

• Open Source Contributions: Tempo is based on the open-source Reth client, and its own core components are expected to be gradually open-sourced. Developers will be able to review the code, submit issues, propose improvements, and even contribute code directly to jointly enhance the protocol's performance and security.
• Validator Participation and Network Governance: Tempo's validator nodes are currently operated by founding partners in a permissioned model, but the long-term plan is to transition to a permissionless model. At that point, any technically capable developer or organization can run a validator node, participate in network consensus, and earn transaction fees in the form of stablecoins while securing the network. As the network decentralizes, a community governance mechanism may also be established, allowing developers to participate in protocol upgrade decisions.
• Protocol Improvement Proposals (TIPs): Developers can draw inspiration from the Ethereum EIPs model by writing and discussing Tempo Improvement Proposals (TIPs) to suggest new features or optimizations to existing mechanisms, thereby directly influencing the protocol's evolution.
• Participating in Hackathons and Developer Challenges: Stripe and Paradigm both have a tradition of supporting developer events. It is foreseeable that once Tempo's developer toolchain matures, there will be dedicated hackathon tracks or prize challenges to encourage developers to innovate on it.
• Community Education & Knowledge Sharing: As early participants, developers can share their experiences and insights by writing technical blogs, creating video tutorials, answering questions in the community, or speaking at technical conferences, helping to grow the entire developer community.

The Tempo ecosystem is in its early stages of construction, providing a valuable opportunity for developers to get deeply involved in various ways and shape its future.

5. Incentives and Grant Programs for Developers​

Currently, Stripe has not formally announced any grant programs or incentives for Tempo developers. At the same time, Tempo's design explicitly rules out issuing a new, speculative native token. However, this does not mean the ecosystem lacks support for developers. It is foreseeable that future incentives will focus more on utility and ecosystem building, and may include:

• Ecosystem Fund: Established by Stripe, Paradigm, or an independent foundation to provide direct grants to teams building critical infrastructure (such as wallets, explorers, analytics tools) or promising applications for the Tempo ecosystem.
• Hackathon Prizes & Bounties: Incentivizing developers through competitions and by posting bounties for specific development tasks, such as developing an open-source library for a particular feature.
• Partner Incentives: For enterprise partners who choose to integrate Tempo into their business, Stripe may offer commercial incentives such as fee reductions, priority technical support, or joint marketing promotions.
• Validator Rewards: Once the network transitions to a permissionless model, running a validator node and processing transactions will provide a continuous stream of income from transaction fees denominated in stablecoins.
• Strategic Investment: For startups that build outstanding products or services on Tempo, strategic investment or potential acquisition from Stripe or Paradigm is also an important incentive.

In summary, Tempo's incentive model will revolve around building real-world value rather than token speculation.
