Stripe and Paradigm-backed blockchain startup Tempo launch the Machine Payments Protocol, which uses Tempo's new blockchain to handle AI agents' transactions

Context & Ripple Effects
Tempo’s machine-payment launch extends a project that had already moved into a public trial for real-world stablecoin payments with named partners. Stripe’s and Paradigm’s involvement gives the effort a direct connection to payment infrastructure rather than positioning it solely as a standalone blockchain project.
Stripe and Tempo now offer a named protocol and Tempo blockchain rail for AI-agent transactions, creating a concrete product surface for agent-payment integrations.
Tempo gains an additional use case for its new blockchain beyond the stablecoin-payment trial, while Stripe is attached to an agent-commerce infrastructure layer.
Second-order effects
Payment providers and blockchain networks targeting stablecoin settlement face a clearer adjacent requirement: support for agent-initiated transactions, not just human checkout or business transfers.
Businesses evaluating Tempo’s stablecoin services can assess one infrastructure stack for both conventional payouts and emerging agent-driven payment flows, potentially tightening the link between those product efforts.
Third-order effects
If agent-mediated buying becomes a durable workload, payment infrastructure may differentiate around the rules, authorization, and settlement rails built for software agents rather than conventional merchant checkout.
This is one step toward permissioned agentic commerce, where control of the transaction layer becomes a strategic position for payment companies and their infrastructure partners.
The trend: Payment and blockchain providers are extending stablecoin-oriented rails into infrastructure for AI agents to transact autonomously.
Tempo Mainnet is live! Starting today, anyone can build on Tempo through our public RPC endpoints. Alongside mainnet, we're introducing the Machine Payments Protocol, an open standard for machine payments. [video]
A few things I like about MPP (machine payments protocol) Payment-method agnostic (supports stablecoins on Tempo, Stripe, cards, Bitcoin lightning, etc) Open and extensible (without our permission) Streaming payments (via state channels) Minimal and efficient
The infrastructure for agentic commerce is being built right now. The decisions we make about credentials, reach and standards will define how agents transact for years to come. 🧵
Enter @Visa's new card spec for Machine Payments Protocol (MPP)—an open standard from @tempo and @stripe—bringing card-based payments into autonomous, machine-to-machine flows. Combined with enablers like @BasisTheory and @getVGS, developers can securely tokenize and orchestrate
MPP differs from other machine payment protocols in that it is payment-rail agnostic and extensible from day one. Tempo developed the initial stablecoin payment method. Stripe added support for its range of payment methods. Visa extended the protocol to enable broader card [image…
Tempo Mainnet is live today! All developers can now use Tempo across Bridge's full suite of products including onramps, offramps, wallets, virtual accounts, issuance, and cards. Tempo is built from the ground up for payments. Instant settlement, predictable low fees, and high
Tempo mainnet is live! We're also launching MPP — a new open standard for machine payments co-authored with Stripe. It's payment rail agnostic — works with stablecoins on any chain but also cards, Lightning network, etc.
Tempo Mainnet is live. Alongside it, we're introducing the Machine Payments Protocol (@mpp) alongside Stripe (with extensions by Visa for cards and Lightspark for Bitcoin). Proud of the team for getting mainnet live so quickly, and excited to see what you build!
@mpp @stripe Beyond agent payments, Tempo can be used for global payouts, remittances, embedded finance, tokenized deposits, and more use cases. We'll be adding more features for enterprises in the coming months. We can't wait to see what you build! More in our blog: https://x.co…
Agent payments will soon overtake human payments on the internet. The Machine Payments Protocol (@mpp) is a new open standard co-authored by @stripe and @tempo. It's designed to be extensible and payment-method agnostic, already supporting stablecoins, cards, and more. [video]
Agents will outnumber human users on the web by orders of magnitude. Just like people, they will need a way to pay for services they use. They may run into propriety health or finance data they need to pay for when doing a deep research task, or make a tool call to a bespoke
