🏗️ System Architecture

Core Components

1. Smart Contract Suite

contract EnterpriseMixer {
    struct Pool {
        uint256 denomination;
        address token;
        MerkleTree tree;
        mapping(bytes32 => bool) nullifiers;
        uint256 anonymitySet;
    }
}

2. Zero-Knowledge Circuit Ecosystem

pragma circom 2.1.0;

template AdvancedMixerCircuit(levels, nAssets) {
    signal input root;
    signal input nullifierHash;
    signal input secret;
    signal input recipient;
    signal input assetSelector;
}

🚀 Quick Deployment

Prerequisites

node --version  # ≥ 18.0.0
python --version  # ≥ 3.10.0

Installation

💻 Developer Quick Start

Basic Usage

from privacy_mixer import EnterpriseMixerClient

client = EnterpriseMixerClient(
    network="mainnet",
    rpc_urls=["https://mainnet.infura.io/v3/YOUR-PROJECT-ID"],
    privacy_level="high"
)

deposit = client.generate_deposit(amount=1.0, asset="ETH")
tx_receipt = client.deposit(deposit)
