Styx Protocol, formerly Protocol 01, is assembled out of other people's work. This page names that work, states the licence it arrives under, and links to the project itself. Rows that named a package this repository does not use were deleted rather than reworded. Upstream repositories still get renamed, transferred and deleted, so a link here can go stale between edits; where a project's own repository has disappeared, the row points at the registry the dependency is installed from.
Our license
This repository is source-available.
Styx Protocol: core protocol and applications
The wallet application, browser extension, Solana programs, proof circuits and SDK sources in this repository are source-available under the PolyForm Strict License 1.0.0, with Volta Team as licensor. Anyone may read, build, run and verify them for noncommercial purposes: research, audit, replaying the benchmark. Commercial use (including production deployment by a business), changes or new works based on the code, and redistribution need a separate written license from Volta Team. Every commit before the one that replaced the MIT License with PolyForm Strict, and every npm version published before 2026-09-22, are available under the MIT License. The full texts live in LICENSE and LICENSE-MIT-BEFORE-POLYFORM at the repository root and are reproduced below, unedited.
Commercial licenses
Noncommercial use needs no permission beyond the license below: read the code, build it, run it, verify a proof, replay the benchmark. Commercial use (including production deployment by a business), changes or new works based on the code, and redistribution need a separate written license from Volta Team, the licensor. This page is where those requests start: write to the address in the notice below.
What was already published stays published under MIT. Every commit of this repository before the one that replaced the MIT License with PolyForm Strict, and every @protocol-01 npm version published before 2026-09-22, are available under the MIT License: a license already granted is not withdrawn. The relicensing commit and later ones, and npm versions published from 2026-09-22 on, ship under PolyForm Strict 1.0.0.

Required Notice: Every commit of the Protocol 01 repository before the commit that replaced its MIT License with this license, and every @protocol-01 npm package version published before 2026-09-22, are available under the MIT License (LICENSE-MIT-BEFORE-POLYFORM in that repository); that grant is not withdrawn.

Third party
29 packages we did not write.
These are the direct dependencies of the wallet, the extension, the web app, the Solana programs and the prover service. Each row repeats the licence that project declares in its own package metadata, and links to the project's repository, or to its registry page where that repository no longer exists.
The proof stack is hash-based: winterfell, SHA-256 and Poseidon, with no elliptic curve anywhere in the proof. The older Groth16 tooling (circom, snarkjs) is no longer a dependency: the last root test scripts that installed it were removed on 2026-09-23.

This list is not exhaustive.
Only direct dependencies are named. A build resolves far more than this, and the count changes with every lockfile. Read the tables as an honest map of what the project chose, not as a complete bill of materials.
The authoritative licence for any package is the text in that package's own repository, not the identifier in our table. If an attribution here is missing or wrong, write to legal@protocol-01.com.
Read this before you rely on it
Two things a reader must not miss. Every package above carries transitive dependencies under their own terms, which this page does not enumerate, so a legal review cannot stop here. And the warranty disclaimer in the licence above is meant literally: this is unaudited devnet software, with no mainnet deployment.
