Trade — Zero-Tolerance Cryptocurrency Trading Platform

Challenge

Build a cryptocurrency trading platform where the primary design goal is preventing catastrophic loss — not maximizing returns. The platform must survive compromised credentials, rogue orders, and operator error with multiple independent safety layers.

Solution Architecture

Defense-in-Depth Design

Five independent components, each with separate credentials and failure domains:
