01·Now- May 2026
Heads-down on staking, infrastructure, and AI automation that actually ships.
Sigmatic is building Stakingverse, operating Sigmacore RPC, supporting EVM teams, and turning practical AI into internal tools, agent workflows, dashboards, bots, and on-chain automation.
Jordy stays close to LUKSO through Foundation work, Universal Profiles, LSPs, builders, validators, growth context, and the infrastructure teams need when the brochure ends and production starts.
02·Flagship- LUKSO + Ethereum liquid staking
Stakingverse is the flagship product.
Stakingverse is Sigmatic's liquid staking product layer. It leads liquid staking on LUKSO with LYX to sLYX flows, and extends into Ethereum staking through integrations using StakeWise V3 infrastructure.
Sigmatic works across product direction, staking UX, infrastructure operations, validator and node maintenance, DeFi mechanics, and the technical translation layer between protocols and users.
- 01$14M peak TVL on Stakingverse.
- 02LUKSO staking through stakingverse.io and app.stakingverse.io.
- 03ETH staking integration using StakeWise V3 infrastructure.
- 04White-glove node, server, validator, and maintenance services for clients.
03·Services

04·Work
The supporting body of work.
Stakingverse is the flagship. The rest shows the operating surface: Foundation work, RPC infrastructure, AI systems, identity, DeFi protocol work, and hackathon proof.
01
Stakingverse
Flagship product
Liquid staking infrastructure across LUKSO and Ethereum, built around usable staking flows instead of validator complexity.
Role

Universal Trust
AI agent reputation
A live on-chain reputation and endorsement protocol for AI agents built on LUKSO Universal Profiles.
Role
Universal Profiles act as agent identities. Agents register, endorse each other, and endorsements accumulate into weighted trust scores through a UUPS-upgradeable registry.
- 2nd place Synthesis AI Agent Hackathon.
- Uses LSP0 and LSP6 identity patterns.
- Tracks endorsements, reputation scores, and activity status.

Universal Profiles & agent identity
Identity proof
Jordy and LUKSOAgent both use Universal Profiles as public identity proof for builder and agent-side work.
Role
Profile-linked identity, agent automation, social proof, and on-chain identity context for LUKSO-native systems.
- JordyDutch Universal Profile.
- LUKSOAgent Universal Profile.
- Separate founder and agent social identities.

05·Stack
Builder and operator, at the same time.
Sigmatic sits in the overlap: deep enough in protocol primitives to build with them, close enough to users to know where the story breaks, and operational enough to keep the infra alive after launch.
Universal Profiles, Key Manager permissions, LSP assets, liquid staking, RPC services, validator operations, DeFi infrastructure, bridge UX, and AI-agent workflows all point at the same problem. Crypto systems need clearer execution.
06·AI
AI automation for blockchain teams and internal operations.
The AI side is broader than OpenClaw. Sigmatic builds agent automation systems including OpenClaw, but also bots, data extraction, LLM tooling, dashboards, website chatbots, and on-chain agent workflows.
Universal Trust and LUKSOAgent show the direction: agent systems with identity, context, reputation, permissions, and visible operating boundaries.
07·Background
Foundation, founder, infra. In that order.
2017
Crypto-native before the institutional brochure era
Hands-on crypto work since 2017, including early Ethereum proof-of-stake and Ethereum 2.0 testnet testing and troubleshooting.
2022
ETHCC Paris hackathon work
Award-winning hackathon execution in Ethereum contexts, long before AI agents became a fashionable slide title.
Aug 2024
Working for the LUKSO Foundation
Started as tech community manager for devs and validators, moved into partnerships and growth, now all-round across ecosystem and developer work where needed.
Now

What people Jordy has worked with say.
From colleagues, managers, and founders who worked with Jordy directly. Originally published on LinkedIn and reproduced here verbatim.
I worked with Jordy through the Foundation for the New Creative Economies (FNCE) and the LUKSO Community.
He's one of the most dedicated, hard-working, and ambitious contributors that we had. He cares, looks at details, and pushes where he thinks things are missing. He is an absolute asset for the community and the project at large. People like him are what make projects move and hold people accountable within.
I can highly recommend Jordy for any project anywhere and I hope we keep him along in the LUKSO community
I had the pleasure of managing Jordy, and he is genuinely one of the most productive and dependable people I’ve worked with.
Jordy combines exceptional organisation and proactivity with a real passion for the work he does. Whatever task or project was put in front of him, he approached it with energy, ownership, and an extremely high standard of execution. Beyond being highly capable, he’s also a fantastic person to work with — collaborative, positive, and someone who builds strong relationships both internally and externally.
Over time, Jordy became one of our go-to people whenever we needed to move quickly and implement something effectively. He developed an impressive ability to use AI agents to rapidly build and improve dashboards, websites, internal tools, and business-critical applications. What stood out most was not just the speed, but the quality and reliability of the output. His productivity reached an exceptional level, even compared to an already incredibly strong baseline.
Any team would be lucky to have Jordy. He brings the rare combination of operational excellence, adaptability, technical fluency, and strong business instincts. I would confidently recommend him to any organisation looking for someone who can execute at a high level, drive growth initiatives, and consistently deliver results.
