Tempo — Payment-Focused L1 Blockchain by Stripe × Paradigm

Tempo is a payment-focused Layer 1 blockchain co-incubated by Stripe and Paradigm. It launched its mainnet in March 2026, simultaneously releasing the Machine Payments Protocol (MPP) for autonomous payments between AI agents, attracting significant attention. This article provides a detailed look at Tempo's features, ecosystem, and roadmap.

Tempo is a blockchain specialized in high-throughput, low-cost payments using stablecoins. It achieves sub-second finality (approximately 0.5 seconds) and fees under $0.001, delivering performance comparable to traditional payment networks. Stripe and Paradigm, two industry leaders, spearheaded development as incubators, with over 100 partners including Visa, Mastercard, OpenAI, and Anthropic participating in the ecosystem.

Its unique design eliminates the need for a native token, allowing users to pay gas fees with stablecoins like USDC and USDT — an approach that sets it apart from existing L1 chains. The testnet recorded throughput of 20,000 TPS, demonstrating the scalability needed for large-scale payment processing.

• Sub-Second Finality: Block confirmation in approximately 0.5 seconds. Deterministic settlement with no reorgs enables real-time payments
• Stablecoin-Native Gas: Pay gas fees with stablecoins like USDC/USDT. No native token required by design
• Machine Payments Protocol (MPP): An open standard for AI agent-to-agent payments, co-developed with Stripe. Over 100 services supported from day one
• Dedicated Payment Lanes: Protocol-level guaranteed blockspace ensures priority processing for payment transactions even during congestion
• EVM-Compatible & TIP-20 Standard: An Ethereum-compatible smart contract environment plus the proprietary TIP-20 token standard with built-in compliance controls and reward distribution

Additionally, Tempo offers a modern wallet with passkey authentication, along with unique transaction types such as batch processing, scheduled payments, and fee sponsorship — making migration from traditional payment systems seamless.

Tempo raised $500M in its Series A round in October 2025, achieving a $5B valuation. This represents one of the largest funding rounds ever for an L1 blockchain.

Beyond its incubators Stripe and Paradigm, Tempo has actively invested in strengthening its technical foundation through a $25M strategic investment in Commonware and the acquisition of Ithaca. Thrive Capital and Greenoaks served as lead investors, with participation from top-tier Silicon Valley VCs including Sequoia Capital, Ribbit Capital, and SV Angel.
