# Deployment Overview

> Overview of Privacy Cash deployment process and environments

Privacy Cash can be deployed to different Solana networks depending on your needs. This section covers the complete deployment workflow from building to verification.

## Prerequisites

Before deploying Privacy Cash, ensure you have the following installed:

* **Solana CLI** 2.1.18 or later
* **Rust** 1.79.0 or compatible version
* **Anchor** 0.31.1
* **Node.js** 16 or later
* **npm** or **yarn**
* **Circom** v2.2.2 - [Installation guide](https://docs.circom.io/getting-started/installation/#installing-dependencies)

## Deployment Environments

Privacy Cash supports deployment to multiple Solana networks:

### Devnet

Development and testing environment. Use this for:

* Testing new features
* Integration testing
* Development workflows

**Program ID**: `ATZj4jZ4FFzkvAcvk27DW9GRkgSbFnHo49fKKPQXU7VS`

### Mainnet

Production environment for live applications.

**Program ID**: `9fhQBbumKEFuXtMBDw8AaQyAjCorLGJQiS3skWZdQyQD`

<Note>
  The mainnet program is fully audited by Accretion, HashCloak, Zigtur and Kriko, and verified onchain with hash `c6f1e5336f2068dc1c1e1c64e92e3d8495b8df79f78011e2620af60aa43090c5`.
</Note>

## Deployment Workflow

The typical deployment process follows these steps:

<Steps>
  <Step title="Build the Program">
    Compile the Solana program using Anchor with appropriate feature flags for your target environment.
  </Step>

  <Step title="Deploy to Network">
    Deploy the compiled program to devnet or mainnet using Anchor or Solana CLI.
  </Step>

  <Step title="Initialize Program State">
    Run initialization scripts to set up Merkle trees and configuration accounts.
  </Step>

  <Step title="Verify Deployment">
    Verify the program build matches the deployed bytecode for transparency.
  </Step>
</Steps>

## Program Configuration

The program configuration is managed in `anchor/Anchor.toml`:

```toml theme={null}
[programs.devnet]
zkcash = "ATZj4jZ4FFzkvAcvk27DW9GRkgSbFnHo49fKKPQXU7VS"

[programs.mainnet]
zkcash = "9fhQBbumKEFuXtMBDw8AaQyAjCorLGJQiS3skWZdQyQD"
```

## Keypair Management

<Warning>
  Keep your deployment keypairs secure. Never commit `deploy-keypair.json` or `zkcash-keypair.json` to version control.
</Warning>

Deployment requires two keypairs:

* **deploy-keypair.json**: Pays for deployment transactions and initializes the program
* **zkcash-keypair.json**: The program's keypair that determines its address
