01·Now- May 2026
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 Sigmatic's liquid staking product layer. It leads LYX staking on LUKSO, with sLYX as the liquid staking token, 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.
03·Services
Sigmatic is not an agency deck with random logos. It is a systems shop for blockchain teams that need working infrastructure.
Smart contracts, backend APIs, staking flows, protocol integrations, Uniswap V3-style infrastructure, cross-chain mechanics, and technical product execution for EVM teams.
EVM · Smart contracts · Backend APIs · DeFi · Cross-chain · Product strategy
DevOps, validator infrastructure, node maintenance, paid archive-node RPC access through Sigmacore, and LSP indexing infrastructure with partner support.

04·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
Flagship product
Liquid staking infrastructure across LUKSO and Ethereum, built around usable staking flows instead of validator complexity.
Role
Founder-led product, infrastructure, staking UX, validator operations, and DeFi positioning by Sigmatic.

04
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.

05
Universal Profiles
Jordy uses a Universal Profile for builder work; LUKSOAgent uses a separate project profile for agent-side work.
Role
Profile-linked context for LUKSO-native systems, agent automation, and social presence.

Confidential protocol work
Work on Uniswap V3 fork infrastructure and cross-chain DeFi protocol systems without naming confidential client or product surfaces.
Role
Protocol-facing DeFi work across routing, liquidity, EVM bridge UX, backend integrations, and operational edge cases.
Uniswap V3 · Routing · Liquidity · EVM bridge UX · Cross-chain · Backend
07
Proof under pressure
Award-winning hackathon work across AI agents, LUKSO, Ethereum, and ETHCC Paris contexts.
Role
Fast technical execution, prototypes, protocol integrations, and working product demos under hard deadlines.
AI · LUKSO · Ethereum · ETHCC · Prototyping
05·Stack
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, EVM bridge UX, and AI-agent workflows all point at the same problem. Blockchain systems need clearer execution.
06·AI
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
2017
Started exploring blockchain in 2017, learning the culture, wallets, and early on-chain products before the space became packaged for institutions.
2020
Started running nodes, testing early Ethereum proof-of-stake networks, and troubleshooting validator and dev infrastructure during the Ethereum 2.0 testnet era.
2022
Award-winning hackathon execution in Ethereum contexts, long before AI agents became a fashionable slide title.
Aug 2024
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
Building Stakingverse, operating Sigmacore RPC, supporting EVM teams, and shipping practical AI automation for blockchain teams.
Universal Profiles
The site links to both public profiles: one for Jordy as builder and founder, and one for LUKSOAgent as the agent project profile.
08·Recommendations
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 have known Jordy for a long time. Our relationship began with technical collaboration, which later evolved into a strong business partnership. Our company has never been let down by him; his involvement has directly driven our growth and significantly enhanced our technological capabilities.
Jordy excels in IT sectors such as Web3 and AI, demonstrating a unique ability to combine both technologies and maximise their potential. We constantly exchange knowledge. Jordy’s potential is virtually limitless – ranging from writing code and managing platforms to leading Web3 and AI project communities, and conducting international C-level business negotiations. We highly value our relationship and the opportunity to collaborate in such rapidly developing sectors.
Jordy is a rare individual who combines high conviction with real execution.
A lot of people can spot problems. Fewer can turn those problems into products, workflows, partnerships, and momentum. Jordy does that consistently. He has an unusually strong work ethic, teaches himself whatever the moment requires, and then applies it in a way that creates leverage for the people around him.
What stands out most is his ownership. If something important is missing, Jordy does not wait for perfect instructions or institutional permission. He figures it out, builds, tests, improves, and keeps going until there is something useful on the table. That showed up clearly in his work around our organization's AI transformation initiatives, where he was early to see the practical value, went deep independently, and then helped others inside and outside the team improve their own workflows.
He also brings a level of honesty that strong teams need. Jordy says what he believes is true, even when it is inconvenient, but he does it because he cares about the project and the community. Earlier on, that intensity could sometimes arrive faster than the room was ready for. What impressed me is that he worked on that. He turned directness into a sharper leadership tool: still candid, still demanding, but more effective at creating alignment across the team.
Jordy has earned respect from builders, community members, partners, and team members because he is not performative. He's been extremely helpful to the team, putting the work first, holds himself and others to a high standard, and has the technical and interpersonal range to move between product, ecosystem, partnerships, and execution.
I would bet on Jordy in any environment that values ownership, speed, integrity, and people who make things happen.
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.
