Yes, it implements Session Keys to limit exposure; agents only have access to a pre-authorized budget. The protocol is built on the Tempo blockchain, which underwent security audits by Paradigm-affiliated researchers.

Q: What is the Purpose of MPP?

The primary goal is to provide a standardized economic interface for AI agents, allowing them to pay for digital services autonomously and efficiently.

Q: How Can I Participate in MPP's Ecosystem?

Developers can participate by integrating the mppx SDK into their AI applications, while users can interact with the ecosystem by using MPP-enabled wallets and agents.

Q: What Sets MPP Apart from Competitors?

Unlike 'crypto-only' solutions, MPP is a full-stack protocol that integrates with traditional banking (fiat) and uses 'Session Keys' to handle high-frequency transactions without constant on-chain congestion.

Q: What are the Risks Associated with MPP?

Risks include potential 'hallucination-led' spending by AI agents and the regulatory uncertainty surrounding autonomous financial actors. These are managed through programmable spending limits and strict KYC/AML layers provided by Stripe.

The mppx TypeScript library provides a typed interface over the Machine Payments Protocol, from high-level abstractions to low-level primitives and building blocks.

What is MPP?

The Machine Payments Protocol (MPP) is an open-source standard co-developed by Stripe and Tempo (in collaboration with Paradigm) to enable native, machine-to-machine payments. It is designed to allow AI agents and autonomous systems to programmatically discover, authorize, and execute payments for resources like compute power, APIs, and data feeds without human intervention.

How Does MPP Work?

MPP revives the long-dormant HTTP 402 'Payment Required' status code. When an AI agent encounters a resource requiring payment, the protocol initiates a challenge-response loop. It utilizes 'Session Keys'—cryptographic primitives that allow an agent to authorize a spending limit for a set duration—enabling thousands of micro-transactions to occur efficiently off-chain or via high-frequency rails like the Tempo blockchain before final settlement.

What Makes MPP Unique?

Unlike traditional payment gateways designed for humans, MPP is optimized for high-frequency, low-latency 'agentic commerce.' It bridges the gap between Web3 and traditional finance by supporting both stablecoins and fiat payment rails (via Stripe). Key features include automated retry logic for payment requests and a developer-friendly SDK that replaces standard fetch APIs with payment-aware capabilities.

Who Are the Founders of MPP?

The protocol was co-authored by engineers and researchers at Stripe and Tempo, with significant backing from the venture firm Paradigm. Notable leadership involves Jesus Rodriguez (CEO of Tempo) and product leads from Stripe's 'Agentic Commerce' suite, leveraging their combined expertise in global payment infrastructure and blockchain scaling.

Latest News

What Key Events Have There Been for MPP?

Significant milestones include the official launch of the Tempo Mainnet in March 2026, which serves as the primary execution layer for MPP. Major industry integrations have been announced with Visa, Mastercard, OpenAI, and Shopify to adopt the protocol for AI-driven transactions. Additionally, Stripe released its 'Agentic Commerce Suite' to allow merchants to accept MPP-based payments.

Project Announcements

Recent updates include the release of the mppx SDK for Node.js and JavaScript, enabling developers to integrate 'mppx.fetch()' into AI agents. Partnerships with Lightspark have also been finalized to enable Lightning Network compatibility within the MPP framework.

Upcoming Events

Latest Airdrop

Tempo has hinted at governance token distributions for early developers and node operators following the mainnet launch; however, specific dates and eligibility criteria for a public 'MPPX' airdrop are currently pending official documentation.

ICO Time

No public ICO has been announced as the project is heavily backed by private venture capital (Paradigm).

IDO Time

There is currently no scheduled Initial DEX Offering (IDO) for an MPPX token.

TGE Time

The Token Generation Event (TGE) for the native Tempo/MPP ecosystem utility token is expected in mid-2026 following the mainnet stabilization phase.

Projects Announcements

Where to Buy MPX?

As of March 2026, the MPX utility token associated with the ecosystem (distinct from legacy tokens of the same name) is primarily traded on decentralized exchanges like Uniswap (Base/Tempo pairs) and has been listed on LBank for initial price discovery.

MPX Price

Daily Trading Volume

The 24-hour trading volume is approximately $215,000, showing a downward trend of 19% as the market stabilizes post-launch.

Market Cap and Valuation

Market Cap

The self-reported market capitalization is approximately $30.6 million, ranking it around #5,400 among active crypto assets.

Fully Diluted Valuation

The FDV is estimated at $32.5 million based on a total supply of 125 million tokens, suggesting most tokens are currently in circulation or allocated.

MPX Price Prediction

There are currently no available forecasts from reliable financial experts or institutional publications. Analysts suggest that the token's value will be highly dependent on the adoption rate of AI agents using the protocol and the continued partnership support from major payment processors like Stripe and Visa.

How to buy MPX?
