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

​
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
The mainnet program is fully audited by Accretion, HashCloak, Zigtur and Kriko, and verified onchain with hash c6f1e5336f2068dc1c1e1c64e92e3d8495b8df79f78011e2620af60aa43090c5.

​
Deployment Workflow

The typical deployment process follows these steps:
1

Build the Program

Compile the Solana program using Anchor with appropriate feature flags for your target environment.
2

Deploy to Network

Deploy the compiled program to devnet or mainnet using Anchor or Solana CLI.
3

Initialize Program State

Run initialization scripts to set up Merkle trees and configuration accounts.
4

Verify Deployment

Verify the program build matches the deployed bytecode for transparency.

​
Program Configuration

The program configuration is managed in anchor/Anchor.toml: 
[programs.devnet]
zkcash = "ATZj4jZ4FFzkvAcvk27DW9GRkgSbFnHo49fKKPQXU7VS"

[programs.mainnet]
zkcash = "9fhQBbumKEFuXtMBDw8AaQyAjCorLGJQiS3skWZdQyQD"

​
Keypair Management

Keep your deployment keypairs secure. Never commit deploy-keypair.json or zkcash-keypair.json to version control.
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
