Build on FxChain
The honest version: there is no public SDK, RPC or testnet today. Here is what exists, what is coming, and how to be there when it opens.
What exists for you right now
A protocol that already exists
FxChain foundations are implemented and sealed on the development line, with deterministic conformance runs on every change. You are not early to an idea - you are early to a proof.
A discipline you can rely on
Sealed history is never re-cut. What becomes public will be versioned, additive and verifiable - the same rules the protocol imposes on itself.
A staged path to your hands
Documentation, specifications and tools arrive in the developer preview stage, each published when it can state proven facts.
Verify without a network
The first thing FxChain intends to put in your hands is not a network. It is a verifier. The first rung of the architecture programme - adoption zero - is offline verification, portable denials, causal accountability and evidence packages, with no network, no token and no migration as a prerequisite.
Concretely: a small offline verifier, as a command-line tool and a browser build, that checks a capsule, a receipt, a portable denial and the committed inputs of a verdict on your machine, against nothing but the artefact itself. Later rungs - an institutional evidence SDK, private supervisory nodes, sovereign execution only where necessity is measured - come after it, each behind its own gate.
Nothing is downloadable today. The verifier is published only when the sealed line produces it under its own acceptance discipline, and it will be announced in the changelog first. Until then, the dossiers are the public reading of what it will verify.
What opens with the developer preview
These surfaces are named and bounded. When one goes live, it is announced here first.
docs.fxchain.network
Documentation and specifications
SDK and client libraries
Typed access to FxChain deployments
Testnet, faucet and explorer
Public experimentation surfaces
api / rpc endpoints
Programmatic access to networks
None of these surfaces is live. docs.fxchain.network does not resolve yet and nothing is published under it. What exists today for a developer is the sealed local line and its public reading: the dossiers and the organ anatomy.
Be there when the gates open.
