OrangeCat

Your AI economic agent — and the platform where it operates.

The Problem

Economic participation still requires gatekeepers. To sell, fund, lend, invest, or govern collectively, you need banks, payment processors, platforms that take cuts and dictate terms. Pseudonymous participation is impossible. AI agents can't transact on your behalf.

The Solution

OrangeCat is an AI-native platform for universal economic participation. The wedge today is a Bitcoin Lightning pay link. "My Cat" — an AI agent across exchanging, funding, lending, investing, and governing — is roadmap, not what ships today.

• Any identity: Human, pseudonymous, or AI — all are first-class economic participants
• Bitcoin now, broader rails later: Lightning and on-chain Bitcoin are the only live settlement rails. Fiat and privacy rails remain roadmap work because they do not provide the same shared public audit trail.
• Full economic spectrum (roadmap beyond the pay link): From gifts (no strings) to loans (some strings) to investments (more strings)
• Private where needed, transparent where chosen: on-chain transparency when appropriate; E2E-encrypted messaging is roadmap — direct messages are stored as plaintext today (realtime, but server-readable)

What Works Today

• Pay link (the wedge): every user gets orangecat.ch/pay/<username> for Bitcoin Lightning payments.
• Site (beta): orangecat.ch
• Shipped surfaces: product/service listings, groups, events, documents, and related entity types exist on the site. Funding, lending, and investing sit on the roadmap.
• Loki dogfood: Loki, the execution layer (deployed at loki.orangecat.ch), uses OrangeCat as a sibling product — typed stakeholder edges, shared BTC wallet, profiles as projects.

Roadmap

• Funding: account-free Bitcoin support for public projects
• Lending: peer-to-peer loans with repayment tracking
• Investing: investment flows beyond the pay-link wedge
• The Cat: AI agent that manages economic activity across the full spectrum

Architecture

15 entity types, one registry. One ownership model (actors), one permission layer (database RLS). Adding a new entity type requires 2-3 files.

Entity Registry Pattern

src/config/entity-registry.ts — single source of truth for all 15 entity types. Drives CRUD, navigation, forms, and validation. No entity-specific switch statements.

Actor System

Users and groups both have actors. All entities reference actor_id. One ownership model, one permission check — works for individuals, organizations, and (future) AI agents.

Middleware Composition

export const POST = compose(withRequestId(), withRateLimit('write'), withZodBody(schema))(handler);

Functional composition replaces inheritance. Each middleware does one thing.

Security

• Row Level Security (RLS) at the database level — bugs in app code can't bypass authorization
• Zod schemas as SSOT — TypeScript types derived from schemas, never separate
• Structured API responses (src/lib/api/standardResponse.ts) across the API routes

Tech Stack

Layer	Technology
Framework	Next.js 16, React 19, TypeScript 6
Styling	Tailwind CSS 4, shadcn/ui
Database	Self-hosted Supabase (PostgreSQL + Auth + RLS) on Hetzner
Bitcoin	Lightning Network, LNURL, bitcoinjs-lib
Auth	Supabase Auth, JWT, Row Level Security
Deployment	Self-hosted on Hetzner (bitbaum, behind Caddy); GitHub Actions CI, then cd.yml deploys

Prerequisites

• Node.js 24 (see .nvmrc)
• A Supabase project (remote — no local Docker needed)

Setup

git clone https://github.com/bitbaum/orangecat.git
cd orangecat
pnpm install
cp .env.example .env.local
# Fill in Supabase credentials
pnpm run dev

Dev server starts at http://localhost:3000.

Environment Variables

See .env.example for the full list. Key variables:

• NEXT_PUBLIC_SUPABASE_URL — Supabase project URL
• NEXT_PUBLIC_SUPABASE_ANON_KEY — Supabase anonymous key
• SUPABASE_SERVICE_ROLE_KEY — Server-side Supabase key

Run your own copy

OrangeCat is MIT. Everything a copy needs is in this repository; nothing points at bitbaum's infrastructure that an environment variable cannot repoint.

• Database and auth: a Supabase project — the free tier works — or the self-hosted Supabase stack (supabase/docker). Point NEXT_PUBLIC_SUPABASE_URL and the keys at it; the schema is supabase/migrations/*.sql, applied in filename order (scripts/apply-migrations.sh).
• Your hostname: set NEXT_PUBLIC_APP_URL. Sitemap, robots, SEO metadata, structured data, emails and the OpenAPI document all build on it (src/config/site-origin.ts); https://orangecat.ch is only the fallback.
• Sibling products are optional: Loki, Solon and the feedback widget are reached through NEXT_PUBLIC_LOKI_URL / NEXT_PUBLIC_SOLON_URL and are simply absent when their keys are unset.
• The contract is .env.example: every variable src/ reads is named there with the file that reads it, and __tests__/unit/ci/env-example-covers-src.test.ts fails CI when one is not. A feature whose key is empty is off, not broken.
• Deploy anywhere Node 24 runs: pnpm run build && pnpm start. The Hetzner scripts under scripts/ are how bitbaum deploys, not a requirement.

The OrangeCat name and visual identity are not part of the licence; a copy should carry its own.

Project Structure

src/
  config/entity-registry.ts  -- SSOT: all 15 entity types
  lib/api/                    -- Middleware composition, generic CRUD
  domain/                     -- Business logic (no HTTP, no UI)
  services/                   -- Currency, search, notifications, groups
  features/                   -- Messaging
  app/api/                    -- API routes (thin, composed from middleware)
  components/                 -- UI components (shadcn/ui based)

Testing

2648 unit tests across 282 files (CI as of 2026-09-02). The pre-push hook runs type-check, file-size and route checks, and the unit tests before code reaches the remote; CI (pnpm run verify) is the gate.

Security

Take it

Bitbaum is a platform for the new economy and for creation: building, engineering and researching. It's a community of builders, creators and researchers, and of the people who support them. We work as engineers in the loop: agents do much of the typing, and people own the judgement.

This code is MIT-licensed so that you can take it. Use it, fork it, rebrand it, sell it, or lift a single file. Make it yours and keep improving it the way you like. You don't need to ask, book a call or sign a CLA. Just keep the LICENSE with your copy.

pnpm dlx degit bitbaum/orangecat my-orangecat   # a clean copy without our git history
cd my-orangecat && pnpm install

• Needs: Node 24, pnpm and a Supabase project (.env.example).
• Make it yours: the name, colours and contact details start in src/config/brand.ts.
• Shared pieces: the @bitbaum/* kits install from public npm or public GitHub, so you need no tokens or private registry.

The OrangeCat name and logo are not covered by the licence, so ship your copy under a name of your own.

More to take: orangecat.ch/steal and github.com/bitbaum.

Want to build it with us? Show us how you think

Copying code is free. What stays scarce once agents and robots write most of it is seeing the whole system. Pick one of these, in this repo, and open an issue or a pull request:

1. Find the second source of truth. Find a fact this code defines in two places. Show how the copies will drift, and say where the one copy should live.
2. Find the silent failure. Pick a promise this system makes. Find where it fails while every check stays green, and propose the check that would catch it.
3. Find where the human belongs. Point to a step where an agent acts alone but a person should decide, or the reverse, and say why.

A real one from this repo: the list of entity types once lived in three docs and drifted in both directions until src/config/entity-registry.ts became the only copy and a test enforced it. Find the next one.

A short, correct answer beats a long one, and so does an answer that admits what it doesn't know.
