+A production-grade, large-scale dataset containing 50 million transactions designed to serve both the beginner data scientist and the enterprise data engineer.
+
+What is inside:
+- 50 million rows of high-fidelity synthetic transaction data
+- 19 carefully engineered fields covering core transaction data, velocity signals, geospatial context, device fingerprinting, and diagnostic fraud labels
