ViaBTC Founder Highlights CoinEx Hot Wallet Security Architecture

ViaBTC founder and CEO Yang Haibo stated that while CoinEx is shutting down, its hot wallet system remains a valuable industry reference. The system utilizes an MPC-based dual-signature scheme to eliminate single points of failure. The infrastructure separates business and wallet systems, managed by independent teams holding separate private keys. Every transaction requires real-time risk control approval from both sides, ensuring security even if one system is compromised. The team spent over a year refactoring the signing process for nearly 300 supported blockchains to avoid reliance on native node mechanisms.
