One stack, three pillars
Fund what is being built, build what people choose to fund, and govern both in the open. Three products, deliberately kept apart — and bound where it counts.
OrangeCatyou are here
Economy
The public economic layer: where a person, project, group, product, or service is explained, shared, supported, offered, or joined — and paid in Bitcoin.
Public by design. Everything here is a page someone can read, share, and settle against without an account.
Loki
Execution
The execution layer: an operator's own workspace for getting work done — agent fleets and the projects they build, alongside the people, commitments and spending that the work runs on.
Private by default, and execution stays behind an approval boundary. Funding never dispatches an agent — the owner approves each plan and each real-world action, and nothing here is published without them saying so.

Governance
The governance layer: where platform-level rules are proposed, voted on with Bitcoin-signed messages, and published as decision documents anyone can re-verify.
Shared with members, and it decides rather than executes. OrangeCat re-verifies every vote signature against its own pinned keys before a decision changes anything.
Visit SolonWhat binds them
They stay separate products because public economic coordination, agent execution, and rule-making have different security boundaries. They are one stack because two of those boundaries are crossed by code you can inspect.
OrangeCat → Loki
Signed build handoff
An owner can send a public OrangeCat entity to Loki as a short-lived, signed build intent. The signature binds the handoff to the owner who approved it. Funding never dispatches an agent on its own — settlement, planning, and execution stay separate events.
Solon → OrangeCat
Verified, not trusted
The ceiling on what the Cat may spend changes only through a Bitcoin-signed Solon vote. OrangeCat re-verifies every signature against its own pinned keys, re-derives each signed message, and recomputes the tally before a policy activates. A Solon decision is evidence, not authority.
Everything built on it
Every project in the studio, as Loki's fleet map records it — what it is, whether it is live, and when it last moved. Each one is a door.

Causius
LiveProduct
The legal layer of the fleet: an agent that does legal work on a sealed case file, a person who decides what leaves it, and licensed lawyers where the law reserves the work for them. Read a letter without an account, or open a matter and let the agent research, keep the deadlines and draft.

Diplodoctor
LiveProduct
The health layer of the fleet: an agent that reads a medical report with you, a person who decides what leaves it, and the people they choose to help: assistants anyone can be, and licensed professionals where the law reserves the work for them. Paste or photograph a lab report and see every value, which ones are outside their printed range, what they measure and what to ask your doctor. Read it without an account, in five languages. An account is there for what comes next (people you choose, matters), not for the reading.
Evig
LiveProduct
evig makes genuinely good computing affordable to everyone — curated, decent hardware people actually want to use, not junk refurb. Founded 2026. This repository is the platform that runs it: a storefront, a community marketplace, repair & IT-help, workshops, an AI-assisted intake pipeline, and an in-house AI assistant.

Open Accounting
not liveNext
Finance is part of building in public, the same way engineering is. A Bitcoin wallet on OrangeCat is non-custodial — the platform watches an address or an extended public key and never holds a key. This project makes such a wallet able to account for itself in public, for owners who choose it: what it holds, what moved, and the owner's own explanation of each transaction. Open accounting is opt-in per wallet, because a wallet is labelled by need and publishing that is the owner's decision, not a side effect of a feature. On top of it goes a transparency score computed from what the platform can observe — whether a wallet publishes its ledger, how much of it is explained — never from claims. An earlier score existed and was deleted in May 2026 because it scored booleans the caller passed in; that is the mistake being corrected.
Osteosynthesis systems

Website design & development — your site live in days, hosted free
not liveNext
A working website — designed, built, deployed, and live on the internet, usually within days. Pricing: CHF 100/hour. A simple site (up to ~5 pages, your text and images, one round of revisions) typically takes 1-3 hours — CHF 100-300 all in. That is not a discount: AI agents do the typing and an automated pipeline does the shipping, so you pay for judgement and taste, not keystrokes. Larger work — web apps, integrations, payments, ongoing changes — runs at the same rate, quoted before I start. Included: design, responsive build tested on real viewports, accessibility basics, SEO metadata, TLS, and deployment. Hosting is free at yourname.orangecat.ch; move to your own domain whenever you like. Live work: orangecat.ch · loki.orangecat.ch · sinktattoo.com · vitareba.orangecat.ch · petvity.orangecat.ch · evig.orangecat.ch Remote, based in Zurich. Settled in Bitcoin over Lightning.

Check it yourself
Don't take this page's word for any of it. The governed state of the stack is published, versioned, and hashed.
- Platform governance — every version of the Cat's spending policy, its content hash, and the Solon decision that legitimated it.
- Solon decisions — every proposal and how its vote went, published by Solon.
- Live governed state — the whole stack as Solon currently sees it.
