# Deployment

{% hint style="warning" %}
ZircoFi contract addresses are published only in `contracts/deployments/4663.json` in the open-source repository, on this page's linked registry, and at [zircofi.com](https://zircofi.com). Addresses circulating anywhere else should be treated as hostile. Verify before approving anything.
{% endhint %}

## Deployments

| Network                 | Chain ID                    | Status                                            |
| ----------------------- | --------------------------- | ------------------------------------------------- |
| Robinhood Chain mainnet | 4663                        | Production                                        |
| Robinhood Chain testnet | Published in the repository | Persistent staging; every release runs here first |

The testnet deployment tracks mainnet parameters and runs against Robinhood's testnet Stock Tokens and faucet assets, so integrators can exercise the full path (attestation, quote, swap, withdrawal) without value at risk.

## The deployment record

`contracts/deployments/4663.json` records, for every contract: address, source commit, compiler settings, constructor arguments, and the deployment transaction. All contracts are verified on Blockscout, and a CI job asserts that on-chain bytecode matches the tagged source on every release, so "the audited code is the deployed code" is a checkable claim rather than a promise.

## Release process

1. Tag, audit or review delta, and publish the source.
2. Deploy to testnet; run the invariant suite and a scripted end-to-end pass against the live testnet oracles.
3. Deploy to mainnet with `CREATE2` for address stability across environments.
4. Wire parameters through the timelock (never in constructors, so the governance log is complete from block one).
5. Update the deployment record and verification, then announce.

Because logic is immutable, a "release" after launch means either a new market from the factory (parameters only, no new code) or a new protocol version deployed alongside the old one, with LPs migrating by choice as described in [Smart contracts](/architecture/smart-contracts.md). Old versions are never switched off remotely; there is nothing to switch.

## Configuration authenticity

Everything a client needs (addresses, market list, tiers, oracle adapters) is readable from `ParamController` and the factory on-chain. The SDK ships with no baked-in market list; it reads the chain, so a stale or tampered client configuration cannot point users at wrong markets without failing signature and address checks.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zircofi.com/architecture/deployment.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
