RPP402 is an open technical standard for autonomous machine commerce. We aren’t selling a hypothetical future we are shipping production ready architecture.

Here is how we differentiate:

• 0 API Keys. 1 Well-Known File.

Publish a single /.well-known/rpp.json file to your endpoint, and your service is instantly discoverable and contractible by any agent on the network. No proprietary dashboard setups.

• Radical Constraint

While other protocols push bloated features, v1 deliberately leaves out 19 future RFCs including Subscriptions, Escrow, and Streaming. We have a clear roadmap and a technical white paper, but we refuse to over engineer ahead of real telemetry. We will build and expand the roadmap in the future based strictly on how the network evolves.

• A Shipped Standard

The complete, MIT licensed protocol is live on npm under the @rpp402 scope. You are one terminal command away from production-ready primitives:

npm install @rpp402/sdk @rpp402/cli

[Robinhood Payments Protocol @rpp402]

The RPP402 registry is entirely permissionless. No gatekeepers, no centralized approvals.

If you are hosting a service node via a /.well-known/rpp.json file, what capability schemas are you exposing to the network?

• Inference endpoints?
• Market data feeds?
• Computational verification layers?

Drop your schemas or link your discovery endpoints below. Let the machines find you.

Our DMs are open.

If you have feedback, technical suggestions, or ideas for a new collaboration within the ecosystem, let us know. We are completely open to discussing how builders want to leverage.

Whether you're looking to integrate or have a new concept to bring to the architecture, get in touch.

You don’t need an enterprise API key or a dashboard to join the machine economy. You need a single file.

Every RPP402 service provider publishes an on-chain path to:
/.well-known/rpp.json

Once that schema is live on your endpoint, any autonomous agent on the network can instantly discover you, request a quote, and execute a verifiable session.

No approval. No gatekeepers. Public discovery.

@RobinFlow_App 2% of the token supply has been locked via @RobinFlow_App .

Honestly, we struggled with how to configure the lock at first, but a huge shoutout to @RobinFlow_App they made the entire process incredibly simple.

Transparency remains our top priority as the standard expands.

@Jorlped_OG $RPP402 settles in stablecoins and tokenized RWAs - the coin isn't the payment rail.
It's the community/coordination layer around the protocol: aligning the people building and running services on it. We're not pretending it's required to move a payment.

[Robinhood Payments Protocol @rpp402]

Exactly. That’s the whole thesis behind $RPP402.

AI agents should not need custom integrations for every service they use. They should be able to discover, quote, pay, settle, and verify through one open protocol.

The machine economy needs a commerce standard, not another payment wrapper.

The $RPP402 Playground is now live.

Run the full machine commerce lifecycle from discovery to receipt using the real @rpp402/sdk against a live local mock service.

No canned demos. No fake responses.

Watch every primitive execute in sequence:

Discovery → Quote → Session → Intent → Settlement → Receipt

You can inspect the request body, response, headers, and state changes at every step.

This is the easiest way to understand how RPP402 works before integrating it into your own service.

[Robinhood Payments Protocol @rpp402]

The npm installation issues have been fully resolved.

You can now cleanly install the packages and run the standard without any friction:

npm install @rpp402/sdk @rpp402/cli

All fixes and updates have been permanently logged on the changelog. If you ran into errors earlier, clear your local cache and retry the install. Everything is live, stable, and ready to go.

[Robinhood Payments Protocol @rpp402]

We’ve run into an issue with the NPM package and are actively working on a fix.

We’ll share an update as soon as everything is stable and ready to use.

Crypto infrastructure treats AI agents like humans with wallets. The Robinhood Payments Protocol (RPP) treats them like autonomous business units.

Built natively on Robinhood Chain, RPP is a complete, machine-native marketplace that allows autonomous systems to transact without human friction.

The framework enables agents to:

Discover each other without central aggregators

Negotiate and sign commercial agreements programmatically

Stream value and settle micro transactions instantly

Cryptographically verify service delivery

Maintain an on-chain reputation score

No human bottlenecks. Just an autonomous economy operating 24/7.
