System Architecture

Introduction

Privacy Pump is built as a collection of specialized systems working together.

Rather than relying on a single smart contract, Privacy Pump separates treasury management, privacy infrastructure, communication, governance, and authorization into dedicated layers.

This modular design improves security, maintainability, and future extensibility.

High-Level Architecture

Privacy Pump consists of five primary layers:

User Interface Layer
Vault Governance Layer
Privacy Layer
Communication Layer
Solana Infrastructure Layer

Each layer performs a specific role within the system.

Layer 1 — User Interface Layer

The User Interface Layer is the application that users interact with.

Responsibilities include:

Vault creation
Treasury management
Proposal creation
Member management
Private routing controls
Private communication

This layer provides access to all platform functionality while abstracting underlying protocol complexity.

Layer 2 — Vault Governance Layer

The Vault Governance Layer manages treasury operations.

Responsibilities include:

Vault ownership
Member management
Approval collection
Rejection collection
Proposal execution
Threshold enforcement

This layer ensures treasury actions follow vault governance rules.

Layer 3 — Privacy Layer

The Privacy Layer reduces unnecessary information exposure.

Primary components include:

Privacy Pump ZK Pool
Private routing system
Privacy set expansion mechanisms
Controlled release queues
Batch routing

This layer helps separate treasury activity from direct blockchain visibility.

Layer 4 — Communication Layer

The Communication Layer enables private coordination between vault members.

Primary component:

Logos-based private vault chat

This layer allows discussions to occur within the vault environment rather than relying entirely on external communication tools.

Layer 5 — Solana Infrastructure Layer

The Solana Infrastructure Layer provides the blockchain foundation.

Responsibilities include:

Transaction execution
Account storage
Program execution
Consensus
Network security

All Privacy Pump operations ultimately settle on Solana.

Core Components

The primary components currently used throughout the system are:

Component	Purpose
Privacy Pump Private Multisig	Treasury governance
Privacy Pump ZK Pool	Privacy infrastructure
Arcium Layer	Private authorization and privacy expansion
Logos Layer	Private communication
Solana Network	Settlement layer

Design Philosophy

Privacy Pump follows three core principles:

Security First

Treasury operations must require explicit authorization and threshold approval.

Privacy By Default

The platform minimizes unnecessary exposure of treasury activity whenever possible.

Simplicity For Users

Advanced privacy systems should not require advanced operational knowledge.

Users interact with vaults, proposals, and treasury operations through familiar workflows while underlying infrastructure handles complexity.

System Flow

A simplified view of the platform is:

Private communication operates alongside these systems through the Logos communication layer.

Key Takeaway

Privacy Pump is not a single application component.

It is a collection of governance, privacy, communication, and authorization systems working together to provide private treasury management on Solana.
