LUKSO development: Universal Profiles, LSPs, and production infrastructure
LUKSO is an open Layer 1 EVM blockchain for social, culture, and creators, running an unmodified Ethereum protocol stack. Its power sits in the standards layer — Universal Profiles and the LUKSO Standard Proposals (LSPs) — and that is exactly where Sigmatic builds.
Sigmatic operates products live on LUKSO today, from liquid staking to archive-node RPC, and its founder works with the LUKSO Foundation. This is production LUKSO development, not a pitch deck.

What Sigmatic builds on LUKSO
LUKSO runs standard Ethereum tooling (chain ID 42, currency LYX), so viem, ethers, wagmi, Foundry, and Hardhat all apply. The difference is the application layer. Universal Profiles are smart-contract accounts built on ERC725 and LSP0, controlled through LSP6 Key Manager permissions rather than a single private key. Sigmatic develops against that model directly, from permission design to the assets and receivers profiles interact with.
- 01Universal Profile integrationsSmart-contract accounts on ERC725 and LSP0, connected through the UP browser extension and @lukso/up-provider.
- 02Key Manager permission designLSP6 controllers that hold specific permissions, so an account delegates scoped rights instead of exposing one all-powerful key.
- 03LSP7 and LSP8 digital assetsFungible LSP7 tokens and identifiable, NFT-like LSP8 assets, described with LSP4 Digital Asset Metadata.
- 04LSP1 Universal Receiver logicReceiver hooks that let profiles and contracts react to incoming assets, value, and notifications.
- 05Relay and gasless UXSponsored transactions through LSP25 Execute Relay Call, so apps can subsidise gas for smoother onboarding.
- 06LSP26 follower and social primitivesOn-chain follow and unfollow for profile-native social features across LUKSO apps.
Tooling runs on the official packages — @lukso/lsp-smart-contracts, @erc725/erc725.js, and @lukso/up-provider — with deployments verifiable on the LUKSO explorer.
02 · Why Sigmatic
Inside the ecosystem, shipping in production.
Jordy has worked with the LUKSO Foundation since August 2024 — first as tech community manager for developers and validators, then across partnerships and growth, now all-round including developer work. That means the standards, the tooling, and the people building on them are the day job, not a research project.
The products are live. Stakingverse leads LYX staking on LUKSO with sLYX as the liquid staking token. Sigmacore provides paid archive-node RPC access and partner LSP indexing. And Universal Trust, an on-chain reputation protocol for AI agents built on Universal Profiles, placed 2nd at the Synthesis AI Agent Hackathon, alongside multiple LUKSO hackathon prizes.
“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.”
