A member-owned liquidity network — not a company, and not a token.
ƒxyz maps currencies, institutions, and settlement corridors as one graph and routes value along the cheapest open path across them. The network is the product. Underneath it, a small set of purpose-built tokens work as accounting mechanisms — they make the graph's economics legible; they are not what we're building, and nothing here is an offer or solicitation of any kind.
This organization hosts what we've made public: infrastructure and visualization code extracted from the ƒxyz codebase as standalone, general-purpose packages, the research foundations behind that work, and — preserved as history — the project ƒxyz grew out of. The ƒxyz application itself stays closed source; this is what we've chosen to open.

Each package below is independently licensed and usable on its own — a plain dataset in, typed data out, no ƒxyz backend required. Start with whichever matches what you're building.
| Repository | What it is | Language | License |
|---|---|---|---|
fxyz-graph |
A headless, backend-agnostic graph-rendering stack: a shared identity/payload contract, a typed algorithm registry (FX routing & arbitrage as siblings to classic centrality/community/pathfinding), force-directed layout with community detection, and a headless controller that drives a swappable rendering backend. Every package takes an in-memory dataset and returns typed data — nothing talks to a database. | TypeScript | Apache-2.0 |
fxyz-e8 |
A zero-dependency implementation of the E8 exceptional Lie group's 240-root system, its H4 folding, and Petrie / stereographic 600-cell projections. 100+ tests assert exact mathematical invariants against the literature; ships a deterministic SVG gallery generated from its own exports. | TypeScript | Apache-2.0 |
fxyz-money-flow |
A gravity-model (Tinbergen) bilateral trade-flow globe, transaction-particle system, and member-point cloud on three.js / React Three Fiber. Visualization only, no personal data by design. Includes a runnable Vite demo. | TypeScript | Apache-2.0 |
fxyz-web-kit |
Standalone Next.js infrastructure — structured logging, telemetry with PII scrubbing on by default, locale middleware, and SEO metadata helpers — extracted from a production, compliance-regulated app. | TypeScript | Apache-2.0 |
fxyz-research |
A curated public bibliography of the research foundations behind ƒxyz — FX routing, settlement, liquidity networks, graph algorithms. Titles, authors, and arXiv/DOI links only; no PDFs, no full text. Browse it → | HTML | CC BY 4.0 (compilation) |
Most repositories carry their own CONTRIBUTING.md and SECURITY.md; the

fxyz-research is the index of
the published work — FX routing, liquidity and settlement networks, graph
algorithms — that ƒxyz's engineering decisions are grounded in. It's a compiled
bibliography, not a paper archive: every entry links out to its own arXiv or
DOI page rather than hosting the source. If you're trying to understand why
something in fxyz-graph or fxyz-money-flow is built the way it is, that's
the place to look.
ƒxyz grew out of Lagrange, a Solana forex/DeFi project. Its repositories are forked here, unmodified, to keep that lineage as public history — they are not actively developed under this organization, and each carries whatever license its original authors gave it:

Triangular-Arbitrage-Data |
GPL-3.0 |
autonomous-arbitrage-analysis |
GPL-3.0 |
FIX-Protocol-Docs |
