CoinEx Founder Highlights Hot Wallet Dual-Signature Security Framework

Yang Haipo, the founder of the digital asset exchange CoinEx, has shared technical insights into the platform's hot wallet architecture, positioning it as a robust model for the broader cryptocurrency industry. Despite the platform's current operational status, the founder emphasized that their security infrastructure, built upon a Multi-Party Computation (MPC) dual-signature scheme, provides a resilient defense mechanism designed to eliminate single points of failure.

Dual-System Isolation and Risk Mitigation

The core of the CoinEx security model relies on the complete separation of its infrastructure into two distinct entities: the business system and the wallet system. According to the technical specifications provided, these units are managed by independent teams, each possessing a unique private key. This structure ensures that no single entity has total control over the movement of funds.

• All asset withdrawals or transfers undergo real-time risk reviews by both systems simultaneously.
• The dual-signature requirement prevents attackers from draining funds even if one system is compromised.
• The architecture utilizes MPC technology to distribute signing authority.

By decoupling the transaction initiation from the signing process, the protocol creates a redundant safety layer that protects liquid assets against unauthorized access or systemic breaches.

Technological Implementation Across 300 Blockchains

Yang Haipo noted that the primary challenge of this security implementation was the need to develop a custom wallet signature process rather than relying on the native mechanisms provided by individual blockchain nodes. The project reportedly spent over a year modifying nearly 300 supported chains to integrate them into this unified, high-security framework.

Even if one system is compromised, attackers cannot directly steal assets. The difficulty of this solution lies in independently implementing the wallet signature process rather than relying on the native mechanisms of each node.

This extensive engineering effort was necessary to ensure that the dual-signature protocol functioned consistently across diverse networks, ranging from major layers like Bitcoin (BTC) and Ethereum (ETH) to smaller altcoin chains.

As the cryptocurrency industry continues to face evolving cyber threats, the adoption of advanced cryptographic methods like MPC and multi-layered system isolation is becoming a standard for centralized exchanges. The technical blueprint shared by the CoinEx founder suggests that while the implementation of such systems is labor-intensive, the resulting security benefits are essential for protecting user funds in an environment where hot wallets remain primary targets for exploitation.
