If you couldn't attend @CardanoSummit and want to watch my talk about why and how we at Serviceplan went all in on #Cardano building @MasumiNetwork together with @nmkr_io - here is the talk:

Good idea!
This is an actual problem for L1s. And it's the main reason why Cardano no matter what needs to start acquiring stake in its protocols & companies.
IMO Cardano should immediately start buying WMTX, SNEK, NIGHT, MIN, STRIKE, LQ, STUFF, IAG, FLDT and others.
It doesn't have to be much. It can be Dollar-Cost-Averaging a little bit every month. But the Treasury needs to hold its top Tokens.
This is in addition to the Treasury owning actual shares of companies through Draper Dragon.
Adding to Patrick: the majority of SMBs in Germany and probably Europe are still at the very beginning of their Journey to embrace AI Agents in their every day work.
For them our Coworkers are simply a great way to embrace the technology - and without them knowing they are starting to leverage Cardano as the underlying trust layer.

NEWS: 🔥 Cardano $ADA is now officially integrated with the x402 standard.
The x402 protocol (originally by Coinbase) enables native, automated, and verifiable on-chain pay-to-access payments between AI agents and services.
The Cardano spec was built by @MasumiNetwork, it's now merged into the x402 repository.

MCP is how an agent calls an API.
Agent Messenger is how agents talk to each other.

The Masumi and CF teams have been working to adopt the latest payments framework x402 on Cardano, which is particularly applicable to agent-to-agent payments challenges. Anyone can use Web3 and pay in a simple and seamless way! Congratulations to everyone involved.
We have big news to share:
Today the x402 foundation has officially merged the Pull Request to add a Cardano Specification of x402 into the repository.
This means Cardano is now officially an x402 chain.
And even better: They have also accepted the Masumi Smart Contract and potentially other Smart Contracts as an optional addition to the standard.
This now makes x402 on Cardano more powerful than x402 on most other chains because it supports:
1) Identity
2) Refunds & Disputes
3) Decision Logging
4) Registry
and more.
We want to give a big shoutout to Fabian from the Cardano Foundation who has spearheaded this 6+ month effort the whole way, improving the Pull Request & talking to Coinbase and the x402 Foundation.
Additionally we want to shoutout Karsten Siebert who has built the first x402 integration on Cardano and was vital in the discussions around the standard.

This is a great achievement for Agent to Agent payments and interoperability for Cardano. Well done to everyone involved
This is epic! Super proud of the team who pulled this of and again a fantastic collaboration with the CF 🙌🚀

Time for an office hour and I will be there today myself finally for the first time. Looking forward to see you there.
When @AnthropicAI introduced the Agent Teams feature in Opus4.6, they allowed an orchestrator to broadcast messages to the team and send messages to single team members.
With our new Agent Messenger you can build the exact same setup, completely Claude agnostic. We at Plan.Studios are actually running a fleet of agents and I just migrated our communication system to our new A2A messenger.
Our Nexus Orchestrator runs a private channel, with all workers listening. And of course each worker + Nexus has his own inbox on our messenger.
The Claude Code based agents check in each /loop the channel and their inbox. The OpenClaw based agents used heartbeat to check his inbox.
Tadaaa: You have a great messaging system for your multi-agent system. No matter what your stack is.
Our messenger for easy Agent-2-Agent comes already with a bigger set of useful features. Check it out: agentmessenger.io/
We are also just launching on product hunt today: producthunt.com/products/mas…
You need to keep it simple. Can't get any simpler than that. Even if you only run Claude Code. You need to try it.
Sebastian Küpers retweeted
Well that launch is not doing very well.
It's a really cool product guys.
Today we are launching the Masumi Agent Messenger. Imagine you have an agent running with OpenClaw - how can your personal agent find and connect with agents from your friends, coworkers or companies?
Just drop the CLI and Skill into your agent and he will now figure it out. Your agent then can:
1️⃣ Register itself with a single command on Masumi
2️⃣ Search for other Agents via email or name
3️⃣ Contact other Agents and start talking directly
If you signup the agent with your email-address, everybody can find agents attached to your email within seconds to unlock simple A2A Use-Cases:
⭐ let your personal agent coordinate a meeting with a personal agent from somebody else within your contacts
⭐ just talk to your personal agent running locally with access to all your data and he hires and coordinate with other agents
Our objective has been to make it as simple and easy as possible and to still give agents lots of options on how they wanna interact with each other.
Let me highlight a few key features:
✅ Everything is Encrypted E2E and Private
✅ The Protocol supports different Headers
✅ You can decide the Authorization it needs
✅ Configure how discoverable your agent is
✅ Group Chats and Public Channels are possible
If you run an OpenClaw, any other agent harness or simply work with Claude Code, Codex or any other coding agent: you can get started within 2 minutes.
Launching on Product Hunt today:

That is a very professional and complete Strategy and totaly support it!
Thanks for the work !
Let's $ADA go to the moon 🚀
We just submitted our budget proposal: "The Marketing-Powered Demand Engine for Cardano."
Here's what it is, what it costs, and why it matters.
THE PROBLEM
Cardano stands on strong technical foundations. Yet for enterprise decision-makers, it's not an obvious "yes" — not because the technology can't deliver, but because they're missing use-case clarity, proof, and engagement paths. The business world sees Cardano as a respected ecosystem. Not yet as first choice for enterprise infrastructure.
THE SOLUTION
A complete enterprise demand generation system that repositions Cardano as "The Blockchain for Serious Business." The system operates through a three-stage funnel: Attention →Proof → Qualified Leads.
Two recommended blueprint verticals: Institutional DeFi and Supply Chain Traceability — final selection to be validated with the GMC. Three pilot markets: UK, Germany, Switzerland. A central Cardano Hub serves as the evidence and engagement environment.
Directly aligned with the Cardano 2030 Strategy Framework — Pillar 2 (Adoption & Utility) and Pillar 4 (Community & Ecosystem Growth), supporting core KPIs: TVL, monthly transactions, and monthly active users.
THE INVESTMENT
12-month pilot. Four milestone-gated work packages — each one only unlocked when the previous one delivers. WP4 (V2 Supply Chain) is only released after the Q3 KPI checkpoint passes. Total investment: €2,978,738 (53% media, 47% agency — within industry benchmark). ADA surplus gets returned to the Treasury.
WHO WE ARE
Serviceplan Group — the only globally ranked agency that has built live Cardano infrastructure, deployed it in production, and holds a formal Cardano Foundation partnership. Official Intersect member. Masumi Network has been on mainnet since November 2024 with 25,000+ on-chain transactions.
Independent Network of the Year at Cannes Lions 2025 (19 Lions). #1 globally on WARC Creative 100 and Media 100. 6,500 people, 40+ countries, €866M revenue.
Full proposal and brochure in the reply below.👇
I am a massive fan of Cardano for a long time now. The technology and engineering pulled me in - now we are building with Masumi on Cardano for almost 1,5 years ourselves. And we constantly deliver what we promise and build AI products used by hundreds of real-world companies already.
I talked over the years to many of our clients about „Why Cardano“ and explained why this blockchain is the only serious option for enterprise use-cases.
When I explain Cardano in my own words, people get excited, ask good questions, see the benefits and are genuinely surprised that they either have never heard of Cardano or had a completely different and mostly false idea of it.
And that needs to change. And you can change this through good communication and by breaking out of the crypto bubble on X.
You need to get Cardano positioned in front of business leaders and shape a perception and narrative about Cardano which not just resonates with them, but enforces our strengths as an ecosystem.
The timing is perfect for this. Never has there been more anxiety across business leaders about digital sovereignty, security, traceability of all things digital & AI. They are all ears to understand what blockchain has to offer.
I would like to encourage you to read the linked PDF below: it shows you our thinking - which is btw already the result of engaging with not just all three founding entities, but also with the GMC, the community and many well known individuals from the community.
I think you can tell we not just did our homework, but we have already put in an considerable upfront investment. We have skin in the game on many different levels. Not just by the pure time invested into this proposal, but even more so by being committed to build on Cardano, to recommend Cardano and bring our clients with us.
We are absolute amazed by the attention this proposal has been getting over the last 24+ hours and I can tell you we read and consider every feedback and comment.
So thanks for reviewing our proposal 🙏 I know it’s a lot to go through. But also absolutely worth it to take a deeper look.
