Crate datasynth_banking 

synth-banking

KYC/AML banking transaction generator for synthetic data.

This crate provides comprehensive banking transaction simulation for:

• Compliance testing and model training
• AML/fraud detection system evaluation
• KYC process simulation
• Regulatory reporting testing

Features

• Customer Generation: Retail, business, and trust customers with realistic KYC profiles
• Account Generation: Multiple account types with proper feature sets
• Transaction Engine: Persona-based transaction generation with causal drivers
• AML Typologies: Structuring, funnel accounts, layering, mule networks, and more
• Ground Truth Labels: Multi-level labels for ML training
• Spoofing Mode: Adversarial transaction generation for robustness testing

Architecture

The crate follows a layered architecture:

BankingOrchestrator (orchestration)
        ↓
Generators (customer, account, transaction, counterparty)
        ↓
Typologies (AML pattern injection)
        ↓
Labels (ground truth generation)
        ↓
Models (customer, account, transaction, KYC)

Usage

use datasynth_banking::{BankingOrchestrator, BankingConfig};

let config = BankingConfig::default();
let mut orchestrator = BankingOrchestrator::new(config, 12345);

// Generate customers and accounts
let customers = orchestrator.generate_customers();
let accounts = orchestrator.generate_accounts(&customers);

// Generate transaction stream
let transactions = orchestrator.generate_transactions(&accounts);
